First record of Phasmarhabditis sp. from eggs of Eobania vermiculata (Müller) snails in Egypt and their response to host size
Authors: Azzam Karima Mahmoud , El-Abd Nema
Published: March 2021

Background

Gastropods are very prevalent animals. In Egypt, terrestrial snails represent important economic pests, infesting and causing severe damages to ornamental plants, orchard trees, vegetables, and field crops. The overuse of molluscicides against these destructive pests leads to more environmental pollution. Therefore, searching for biological control agents became necessary to avoid the hazard of chemical molluscicides. Phasmarhabditis hermaphrodita, isolated from slugs was used as a bio-control agent against snails and slugs. Few investigations available on gastropod egg parasites. Therefore, the present study interested in the isolation of parasitic nematodes from the snail eggs to study their possible role as biological control agents for gastropod pests.

Results

This is the first record to isolate the snail parasitic nematode, Phasmarhabditis sp., from eggs of the Egyptian terrestrial snail, Eobania vermiculata (Müller). Infectivity of this nematode was investigated for eggs, juvenile and mature snails, E. vermiculata and Limax flavus L. slugs, and also eggs of the non-local species, Achatina fulica Bowdich and one adult of it was only available. The investigation revealed a capability of the isolated nematode to infect and kill E. vermiculata snail, L. flavus slugs, and their eggs. Also, it could infect and kill the eggs of non-local snail species, A. fulica, and its only individual adult available which was obtained from an agricultural quarantine sample. The results indicated also that released individuals of the nematodes, recovered from snails, were significantly larger in size than those recovered from eggs and vice versa.

Conclusion

It could be concluded that the isolated parasitic nematode may be able to play a role in controlling different stages of the gastropods including eggs. This make the control more effective in protecting host plants before the pest causing damage. The nematode was more effective on local pest species than non-local species. Moreover, the size of the parasite was proportional with the size of the host pest.
Potent antioxidant peptides derived from honey major protein enhance tolerance of eukaryotic cells toward oxidative stress
Authors: Ibrahim Hisham R. , Nanbu Fukiko , Miyata Takeshi
Published: March 2021

Honey is known for its medicinal benefits and receiving renewed attention as natural medicine. Studies on health benefits of honey attributed its antioxidant activity to phenolic compounds, but the contribution of proteins and peptides to the antioxidant activity of honey is lacking. The aim of this study was to explore the contribution of proteins and peptides to the antioxidant activity of honey, which remained obscure for decades.

Total honey proteins (THP) were isolated by dialysis method and hydrolyzed through simulated gastrointestinal digestion. The hydrolysates were fractionated using size-exclusion chromatography. The antioxidant activity was determined by using superoxide radical-scavenging, DPPH reduction and intracellular ROS assays.

THP was shown to exhibit superoxide-scavenging activity but its pepsin-hydrolysate (HP-p) showed superior scavenging activity. The HP-p produced five peptide fractions (P1~P5) when fractionated on Sephacryl S-100 size-exclusion column. The five fractions showed superoxide-scavenging activities and DPPH reducing activities, whereas the slow-eluting peptide fractions (P3 and P4) were the most potent. MALDI-TOF/MS analysis identified a pentapeptide (TSNTF) as the dominant peptide in the active fractions P3 and P4. Human colonic epithelial cells treated with P3 and P4 peptides exhibited lower intracellular ROS, when oxidative stress was induced by H2O2or diethyl maleate (DEM), indicating strong tolerance to oxidative stress. The viabilities of human cells or yeast cells were largely decreases under oxidative stress, but treated cells with P3 and P4 showed higher viability compared with the untreated cells. The results are the first to describe a novel antioxidant peptide from honey that confer ex vivo anti-oxidative function within a complicated milieu of eukaryotic cells and pave the way for its potential as nutraceutical or therapeutic peptide for risk-reduction of oxidative-stress and related diseases.

George Herbert’s “The Flower” and the Problem of Praise
Authors: Kuzner James
Published: March 2021

This essay dwells on George Herbert’s “The Flower” and on how its speaker can love and praise God. Writing of praise and doubt, Stanley Cavell remarks that the problem of skepticism is partly a problem of finding an object that one can praise, a search that certainly occurs in “The Flower.” While Herbert’s speaker seeks God as that object, his own memory impedes him, making him question God’s goodness and forcing him not only to abandon forms of remembering that Herbert’s sources—from psalmists to theologians—employ so as to rise to praise, but also to use form in order to forget. The essay’s conclusion compares Herbert’s poem with another strange praise poem, Paul Celan’s “Psalm.” The essay claims that if Cavell sees praise as signaling a triumph over doubt, “The Flower” shows, as only verse can, how praise and doubt accompany each other, using doubt to keep praise at a distance from both psalmic theology and skeptical philosophy.
Reinventing Modernism: Randall Jarrell’s Unwritten Essay on T. S. Eliot
Authors: Cuda Anthony
Published: March 2021

Despite a wealth of new primary-source publications and archival discoveries, many scholars persist in the belief that midcentury poets like Randall Jarrell rejected their modernist predecessors in a quest for originality and novelty. This article demonstrates, on the contrary, Jarrell’s underestimated and enduring creative debt to T. S. Eliot by reconstructing, for the first time, a book-length essay that he planned to write about Eliot but abandoned. The article shows that Jarrell regarded Eliot’s work as the result of a psychological struggle with “obsessional neurosis,” and it reveals the logic and evidence that Jarrell planned to use to argue this claim. It concludes by showing that Jarrell himself adapted aspects of Eliot’s obsessional style in his poetry and hoped to follow them to a different end.
A Caenorhabditis elegans behavioral assay distinguishes early stage prostate cancer patient urine from controls

Published: March 2021

Current methods for non-invasive prostate cancer (PrCa) detection have a high false-positive rate and often result in unnecessary biopsies. Previous work has suggested that urinary volatile organic compound (VOC) biomarkers may be able to distinguish PrCa cases from benign disease. The behavior of the nematode Caenorhabditis elegans has been proposed as a tool to take advantage of these potential VOC profiles. To test the ability of C. elegans Bristol N2 to distinguish PrCa cases from controls, we performed chemotaxis assays using human urine samples collected from men screened for PrCa. Behavioral response of nematodes towards diluted urine from PrCa cases was compared to response to samples from cancer-free controls. Overall, we observed a significant attraction of young adult-stage C. elegans nematodes to 1:100 diluted urine from confirmed PrCa cases and repulsion of C. elegans to urine from controls. When C. elegans chemotaxis index was considered alongside prostate-specific antigen levels for distinguishing cancer from cancer-free controls, the accuracy of patient classification was 81%. We also observed behavioral attraction of C. elegans to two previously reported VOCs to be increased in PrCa patient urine. We conclude nematode behavior distinguishes PrCa case urine from controls in a dilution-dependent manner.
Non-commercial pharmaceutical R&D: what do neglected diseases suggest about costs and efficiency?
Authors: Vieira Marcela , Kimmitt Ryan , Moon Suerie
Published: March 2021

Background: The past two decades have witnessed significant growth in non-commercial research and development (R&D) initiatives, particularly for neglected diseases, but there is limited understanding of the ways in which they compare with traditional commercial R&D. This study analyses costs, timeframes, and attrition rates of non-commercial R&D across multiple initiatives and how they compare to commercial R&D using the Portfolio-to-Impact (P2I) model as parameter of comparison.

Methods: This is a mixed-method, observational, descriptive and analytic study. We contacted 48 non-commercial R&D initiatives and received quantitative data from 8 organizations on 83 candidate products, and qualitative data through 14 interviews from 12 organizations.

Results: The quantitative data suggested that non-commercial R&D for new chemical entities is largely in line with P2I averages regarding total costs and timeframes, with variation by phase. The qualitative data identified more reasons why non-commercial R&D costs would be lower than commercial R&D, timeframes would be longer and attrition rates would be equivalent or higher, though the magnitude of effect is not known. The overall emerging hypothesis is that direct costs of non-commercial R&D are expected to be equivalent or somewhat lower than commercial, timeframes are expected to be equivalent or somewhat longer and attrition rates would be equivalent.

Conclusions: The study found that non-commercial R&D differs in many significant ways from commercial R&D. However, it is possible that the sum of these differences cancelled each other out such that total costs, timeframes and attrition rates were largely in line with P2I averages. Given the nascent area, with almost no prior literature focusing on costs, timeframes or attrition rates of non-commercial R&D initiatives, we see the merits of this study as generating hypotheses for further testing against a larger sample of quantitative data, and for understanding reasons underlying any significant differences between non-commercial and commercial initiatives.

Published: March 2021

Background: Convalescent plasma (CCP) has been used for treating some infectious diseases; however, the efficacy of CCP in coronavirus disease 2019 (COVID-19) remains controversial. The aim of this research was to assess the efficacy of CCP as an adjunctive treatment in COVID-19 patients.

Methods: Embase, PubMed, Web of Science, Cochrane and MedRix were searched for potentially relevant articles. All included papers were assessed for the quality using modified jadad scale and Newcaste-ottawa scale for randomized controlled trial (RCT) and non – RCT, respectively. We used a Q test and Egger test to assess the heterogeneity and publication bias among studies, respectively. Mortality rates between patients treated with standard treatment and standard treatment with CCP were compared using a Z test.

Results: A total of 12 papers consisting of three cross-sectional studies, one prospective study, five retrospective studies, and two RCT studies were included in our analysis. Of them, a total of 1,937 patients treated with CCP and 3,405 patients without CCP were involved.. The risk of mortality was 1.92-fold higher in patients without CCP compared to patients treated with CCP (OR: 1.92; 95%CI: 1.33, 2.77; p=0.0005). In severe COVID-19 sub-group analysis, we found that patients without the CCP had a 1.32 times higher risk of mortality than those treated with the CCP (OR: 1.32; 95%CI: 1.09, 1.60; p=0.0040).

Conclusions: CCP, as adjunctive therapy, reduces the mortality rate among COVID-19 patients.

Centralized or Decentralized Transfer Prices: A Behavioral Approach for Improving Supply Chain Coordination
Authors: Katok Elena , Villa Sebastián
Published: March 2021

Problem definition: We study supply chain coordination in a setting with transshipment. We use centralized and decentralized transfer prices as a way to increase supply chain coordination. Academic/practical relevance: The ability to transship can improve channel efficiency by improving the match between supply and demand. We study how human decision makers behave in this setting and provide clear insights to improve coordination. Methodology: We use controlled laboratory experiments with financially incentivized human subjects. We study a broad set of critical ratios under both decentralized and centralized transfer-price settings. In the decentralized transfer-price setting, retailers negotiate a transfer price. In the centralized transfer-price setting, we use two different approaches: theoretical and behavioral transfer price. Both approaches suggest opposite recommendations. Results: Analytically, the optimal transfer price should depend on the critical ratio; but results from the decentralized setting show that participants set prices as if they ignore the critical ratio and instead focus on splitting potential profit from transshipped units in half. However, there is a positive relationship between transfer prices and ordering decisions. Moreover, generalizing the pull-to-center effect, we find that subjects do not place orders that coordinate the supply chain. For the centralized setting, we find that using the theoretical approach does not coordinate ordering decisions and does not improve decisions compared with the decentralized setting. The behavioral approach suggests a transfer price close to product selling price for a high critical ratio and a transfer price below product cost for a low critical ratio. These recommendations lead to coordinating ordering decisions. Managerial implications: We draw two practical conclusions from our research. First, transshipments are unambiguously beneficial, resulting in higher profitability, and, when feasible, should be encouraged. Second, when possible, transfer prices should be set centrally but taking into account subjects’ behavior. Otherwise, price negotiation might lead to better performance.
Relational Work and the Knowledge Transfer Process: Rituals in Rural Ghana
Authors: Slavova Mira , Metiu Anca
Published: March 2021

We advance understandings of knowledge transfer by showing the central role of symbolic action, taking the form of ritual, in contexts characterized by worldview differences. Using qualitative data from interactions between farming communities in rural Ghana and agriculture development specialists, we examine how rituals do relational work that enables informational work. We find that rituals (i.e., visits, value affirmations, gift-giving, prayer, performing, storytelling) do so by means of their functions–bracketing worldview differences, modeling collaboration between farmers and agriculture development specialists, and packaging new knowledge in displays of compatibility. Our work also expands scholarship on the role of rituals in organizations and on management practices in Africa. Overall, our paper offers a complex, comprehensive view of knowledge transfer as involving both relational and informational work and relying on both symbolic action and tangible elements.
An infarcted wandering spleen leading to a sigmoid volvulus presenting with acute large bowel obstruction: a case report
Authors: Hamdy O , Yousry M , Saleh GA
Published: March 2021

A wandering spleen is a very rare event characterised by the absence of the spleen in its anatomical position due to the hyperlaxity of its ligaments. We present a case of wandering spleen complicated by splenic vascular pedicle torsion, thrombosis and subsequent splenic infarction. Compression of the infarcted spleen on the rectosigmoid junction led to the development of a sigmoid volvulus, which presented as an acute large bowel obstruction. The patient underwent emergency laparotomy, splenectomy, sigmoid decompression and sigmoidopexy. After a follow-up period of two years, the volvulus had not recurred.
MOSTWAS: Multi-Omic Strategies for Transcriptome-Wide Association Studies
Authors: Bhattacharya Arjun , Li Yun , Love Michael I.
Published: March 2021

Traditional predictive models for transcriptome-wide association studies (TWAS) consider only single nucleotide polymorphisms (SNPs) local to genes of interest and perform parameter shrinkage with a regularization process. These approaches ignore the effect of distal-SNPs or other molecular effects underlying the SNP-gene association. Here, we outline multi-omics strategies for transcriptome imputation from germline genetics to allow more powerful testing of gene-trait associations by prioritizing distal-SNPs to the gene of interest. In one extension, we identify mediating biomarkers (CpG sites, microRNAs, and transcription factors) highly associated with gene expression and train predictive models for these mediators using their local SNPs. Imputed values for mediators are then incorporated into the final predictive model of gene expression, along with local SNPs. In the second extension, we assess distal-eQTLs (SNPs associated with genes not in a local window around it) for their mediation effect through mediating biomarkers local to these distal-eSNPs. Distal-eSNPs with large indirect mediation effects are then included in the transcriptomic prediction model with the local SNPs around the gene of interest. Using simulations and real data from ROS/MAP brain tissue and TCGA breast tumors, we show considerable gains of percent variance explained (1–2% additive increase) of gene expression and TWAS power to detect gene-trait associations. This integrative approach to transcriptome-wide imputation and association studies aids in identifying the complex interactions underlying genetic regulation within a tissue and important risk genes for various traits and disorders.
Alfacalcidol improves the growth velocity in children with vitamin D deficiency/insufficiency: A single center retrospective cohort study
Authors: Miyagaki Satoshi , Yamaguchi Mihoko , Ota Takeshi , Kawabe Yasuhiro , Morimoto Hidechika , Oka Yoshinobu , Mori Jun
Published: March 2021

Objectives

To investigate the growth velocity-improving effects of vitamin D replacement therapy in pediatric patients diagnosed with vitamin D deficiency and insufficiency.

Study design

A retrospective cohort study was conducted in 34 pediatric patients diagnosed with vitamin D deficiency/insufficiency. Based on the clinical findings, the subjects were divided into two groups: a bowed leg (BL) group and a non-bowed leg (non-BL) group. After the initiation of alfacalcidol, the standard deviation score (SDS) of their heights, weights and growth velocities in each group were monitored.

Results

The median age at the first visit was significantly lesser in the BL group (1.58 years old [interquartile range (IQR): 1.33, 2.17]) than that in the non-BL group (3.00 years old [IQR: 2.33, 3.67]). On the contrary, the SDS for height was significantly lower in the non-BL group (-2.27 [IQR: -2.63, -1.94]) than that in the BL group (-1.37 [IQR: -1.91, -1.07]). One-year treatment with alfacalcidol showed significant improvements in both height SDSs and growth velocity SDSs not only in the BL group but also in the non-BL group.

Conclusions

The current study revealed that vitamin D replacement therapy improved the growth rate in children with vitamin D deficiency/insufficiency, regardless of the presence of BL. This study emphasizes the importance of assessing the vitamin D status in children with poor growth rates and suggests that alfacalcidol could be a valid option for the treatment of short stature.
Stance markers in English medical research articles and newspaper opinion columns: A comparative corpus-based study
Authors: Shen Qian , Tao Yating
Published: March 2021

Stance markers are critical linguistic devices for writers to convey their personal attitudes, judgments or assessments about the proposition of certain messages. Following Hyland’s framework of stance, this study investigated the distribution of stance markers in two different genres: medical research articles (medical RA) and newspaper opinion columns (newspaper OC). The corpus constructed for the investigation includes 52 medical research articles and 175 newspaper opinion articles, which were both written in English and published from January to April in 2020 with the topic focusing on COVID-19. The findings of this study demonstrated that the occurrences of stance markers in newspaper OC were far more frequent than those in medical RA, indicating the different conventions of these two genres. Despite the significant difference in the occurrences of stance markers between the two sub-corpora, similarities of the most frequent stance markers in two genres were also highlighted. The study indicated that the topic content seems to play an important role in shaping the way of how writers construct their stance. The lack of information or evidence on the topic of COVID-19 could restrain writers from making high degree of commitment to their claims, which make them adopt a more tentative stance to qualify their statements.
A felzárkóztatás nehézségei és támogatásának lehetőségei a gyengén teljesítő iskolákban
Authors: Szabó Dóra Fanni , Tóth Edit , D. Molnár Éva
Published: March 2021

Számos hazai és nemzetközi vizsgálat hívta fel a figyelmet arra, hogy a tanulók szocikulturális környezete, a megfelelő oktatási szolgáltatásokhoz és motiváló iskolai környezethez való hozzáférés jelentősen befolyásolja az iskolai eredményességüket. A különböző szempontok mentén, rendszeresen összegyűjtött információk elemzése hozzájárulhat a gyengénteljesítő intézményekben létrejövő hatásmechanizmusok megértéséhez és ezáltal a probléma megoldásához kapcsolódó intézkedési tervek és komplex cselekvéssorok kialakításához. Vizsgálatunkkal arra a kérdésre kerestük a választ, hogy az Országos kompetenciamérésen alacsony teljesítményt elérő intézmények vezetői szerint (1) milyen tanulói és intézményi szintű okok vezetnek iskolájukban az alacsony eredményességhez, a felzárkóztatás sikertelenségéhez, s (2) milyen területeken azonosítják a beavatkozás szükségességét.Zárt és nyílt végű kérdésekkel gyűjtött eredményeink szerint a tanulói szintű tényezőket gyakrabban előforduló nehézségként ítélik meg az intézményvezetők (N=68), mint az intézményi szintűeket. A leggyakrabban előforduló nehézségek között jelent meg a tanulók tanulási módszereinek elégtelen volta, alacsony motivációja, valamint a szülők iskolához, tanuláshoz való viszonyulása. Az intézményi szintű hátráltató tényezők között meghatározó a pedagógusok leterheltsége, a felzárkóztatást, fejlesztést segítő szakemberek hiánya. A fejlesztés lehetőségeit a beavatkozás szükségességét a leginkább problémásnak ítélt területeken látják az intézményvezetők. A nyílt kérdésekre adott válaszok alapján ugyanakkor a legnagyobb erőforrást a pedagógusok továbbképzésében látják az intézményvezetők.

Hosszú ideje a vita az ügyfélhűség fontosságáról szól, és számtalan forgatókönyvet találhatunk arra vonatkozóan, hogy hogyan tartsuk meg fogyasztóinkat, és annak milyen pozitív hatásai lehetnek a B2C piacokon a szervezetek teljesítményére. Sajnos ugyanez nem mondható el a vállalatok közötti (B2B) lojalitásvizsgálatokkal kapcsolatban. Sokkal kevesebb az elméleti fejtegetés, és sokkal kevesebb az empirikus kutatás ezen a területen. A lojalitás kérdésében kétségtelenül több a hasonlóság, mint a különbség a B2B és a B2C piacokon, de mégis nagyobb figyelmet érdemelne az olyan tényezők vizsgálata a B2B piacokon, mint az érték, a kapcsolatépítés, az elkötelezettség, a bizalom, a kölcsönösség. A tanulmány egy átfogó empirikus kutatás kvalitatív vizsgálati eredményeivel kíván rávilágítani arra, hogy miként is vélekednek az egymással kapcsolatban lévő szervezetek a B2B lojalitásról.

Published: March 2021

La violencia de género es un problema de salud pública que debe abordarse desde un ámbito preventivo, multidisciplinar e integral. Pese al gran número de medidas desarrolladas y de recursos existentes, aún hoy en día, son pocos los estudios que analizan la efectividad y el impacto de este tipo de recursos sobre las víctimas y la sociedad en general. El presente trabajo tiene un triple objetivo: (1) valorar el impacto de las medidas legislativas y las actuaciones preventivas a partir de la Ley Orgánica 1/2004 de medidas de Protección Integral contra la Violencia de género, (2) determinar el grado de utilización de dichos recursos y (3) detectar posibles necesidades de intervención. Para ello, se realiza un análisis detallado de los recursos disponibles tras la aprobación de la Ley en función del nivel de prevención al que van dirigidos. Se utiliza como fuente de información la base de datos del Portal Estadístico del Ministerio de Sanidad Servicios Sociales e Igualdad y, se analizan las diferencias existentes en denuncias por violencia de género y llamadas al 016 entre 2004 y 2015. Finalmente, se concluye sobre el impacto social de las medidas desarrolladas a partir de la aprobación de la Ley Orgánica 1/2004.

Virtual Instructional Packages and Pre-Service Language Teachers' Communicative Skills: Empirical evidence from Nigerian Colleges of Education.
Authors: FALOYE Bankole Olagunju , Obateru Oluwatoyin Tolu
Published: March 2021

The study investigated the effect of virtual instructional tools on the learning outcomes of pre-service English language teachers in Nigerian Colleges of Education. The rationale of the study was hinged on the premise of virtual instructional adaptation in a post-OVID-19 era. The design for the study was a two- group pre-test post-test quasi-experimental design. The research design comprised pretest and post-test observations, treatment with virtual instruction and normal instruction in a non-virtual space. Using multistage sampling strategy, 100 samples were randomly selected from two Colleges of Education in Southwest Nigeria. The experimental and controls groups consisted of 50 samples each comprising 25 females and 25 males. The instruments for the study were validated achievement tests and marking guides including a test-retest reliability study with a reliability coefficient of 0.87 which was considered as moderately high for the reliability of the instruments. Two null hypotheses were raised and tested at 0.05 levels of significance using Two- Way ANOVA as statistical tools. The findings revealed that there was significant effect of virtual instructional tools on pre-service English language teachers’ learning outcomes using the  pre-test mean scores and post-test mean scores. Also, the findings showed that there was significant gender effect of virtual instructional tools on the virtual learning outcomes of pre-service English language teachers’ communicative skills in English. Pedagogical implications of the findings in respect to virtual instructional tools in a post-COVID-19 era were highlighted and suggestions preferred towards enhancing pedagogical and communicative competencies of pre-service English teachers in Nigerian Colleges of Education.

Published: March 2021

The purpose of this study was to examine the moderating effect of the status of using the product on the relationship between brand experience, satisfaction, loyalty and brand recommendation. Structural equation modeling (SEM) with multi groups was used for data analysis. The results of this study indicate that there is a strong relationship between brand experience, satisfaction, loyalty and brand recommendation. The effect of brand experience and brand satisfaction on WOM recommendations was higher in the new user group than in the established user group. While the effect of brand loyalty on WOM recommendations was higher for established users than for new users. The effect of brand experience on brand satisfaction was greater for established users than for new users.

National Regulations and Local Rules - A Hybrid Regulatory Model of Intelligent Connected Vehicles in China
Authors: Liu Huichun
Published: March 2021

This paper investigates the laws and regulations of China on the intelligent connected vehicles (ICV). After analyzing the current Chinese laws that are related to the ICVs, this paper makes a list of challenges that the current legal framework needs to face if (1) the ICV-related laws are not revised or new laws are not passed, and (2) there are no regulations or rules made to govern the legal issues of the ICVs. Then this paper starts to focus on the research into the national regulations and local government rules. In this part, literature review of the regulations of the central government and the rules of the local government is completed to investigate how this hybrid model works for the development of ICV industry in China. Detailed analysis of text of provisions is provided. The results indicate that the interaction and interconnection of the regulations at the national level and local government level form an underlying framework for the Chinese ICV industry by providing guidance, policies, and implementation rules.
Exile and homesickness in the poetry of Ahmad Shawqi
Authors: Al-Rifai Nada Yousuf
Published: March 2021

Ahmad Shawqi was raised in the royal palace, where his maternal grandmother – who sponsored him after the death of his mother – was a favoured maid at Khedive Ismail. Shawqi studied law in Egypt and Paris, and when he returned to Egypt, he became poet Laurette for Khedive Abbas Helmy II. Although Shawqi was brought up in the royal palace, as a poet, he felt the pulse of the Egyptian people and felt their pain and dreams. After the First World War broke out, in 1915, Shawqi was exiled to Spain where he was swept away by longing for his homeland. During his exile, the 1919 revolution erupted in Egypt, and his longing for his homeland intensified, and obsessed his heart and soul. Exile was the greatest ordeal that Shawqi went through in his life. In exile, he did not find relief except when resorting to his poetry, to which he revealed the pains of his heart. He also visited the memorials of the Muslims and their reign and civilization in Seville, Cordoba, and Granada. This resulted in Shawqi composing his lengthy poem “Arab countries and the greats of Islam”. Shawqi’s poems are considered masterpieces for their sincerity of emotion and beauty of description. Perhaps the most famous of these is The Seeniya; rhyming with the letter S, entitled “The Journey to Andalusia”, and his other longing poem, “The Nouniya; rhyming with the letter N”, in which he opposed the famous medieval Arab Andalusian poet, Ibn Zaidoun.
The Nexus Between Organisational Justice, Job Satisfaction, and Organisational Citizenship Behaviour: The Case of Barclays Bank
Authors: Ocra Ben T.
Published: March 2021

This study examined the nexus between organisational justice, OCB, and job satisfaction. It also attempted to control for relevant covariates to contribute to the literature. The study was a correlational design, and its population was employees at the head office of Barclays Bank Ghana Limited (BBGL). All two hundred and seven (207) employees who met some selection criteria participated in the study. A self-administered questionnaire was used to collect data. Data was analysed using SPSS (Statistical Package for the Social Sciences). Descriptive statistics, Pearson’s correlation test, and Structural Equation Modelling (SEM) were used to present findings of the study. Organisational justice made a positive effect on job satisfaction and organisational citizenship behaviour. Job satisfaction also made a significant positive effect on organisational citizenship behaviour. It is concluded that increasing the level of justice delivered can improve the level of job satisfaction and organisational citizenship behaviour.
Problematising the Dominant Child Rights Discourses: Why We Need a Nuanced Approach to Combat Child Labour
Authors: Mohammed Abdul-Rahim , Achanso Adams Sulemana
Published: March 2021

Three decades have now passed since the promulgation of the United Nations Convention on the Rights of the Child (CRC) in 1989. Despite the almost universal ratification of the CRC, as well as the heightened global awareness of the prevalence of child labour, the phenomenon persists. Following the ratification of the CRC, the rights-based approach to combating child labour became the dominant theoretical perspective. By problematising the dominant child-rights framework, this paper contributes to the discourse on child labour by arguing for a more nuanced approach to addressing the phenomenon. The paper achieves this objective by underscoring the importance of understanding and engaging with the reasons why children work, the socio-economic contexts within which they work, and why policies designed to address child labour should address the structural barriers that directly and indirectly promote child labour.
Correlation Modes Initial Setting Investigation-Based Group Inquiry Model Formulating Grant Hypotheses Against Student Ability in Science Skills

Published: March 2021

In the implementation of experimental activities, the competence that is expected to be mastered by a student is to appreciate the various concepts and principles of advanced physics by conducting various physics experiments and being able to develop creativity in designing experiments. Physics lessons are subjects related to numbers and some abstract concepts. The study aims to determine the correlation of the Initial Setting variable (X) of the Investigation-Based Group Inquiry Model to the science process skills variable (Y). Data analysis used a single linear regression correlation test using SPSS. The research sample was physics students. The data analysis technique used in this research is the statistical analysis technique of quantitative data calculations. The results of the analysis for the coefficient of determination R Square of 0.251 indicate that 25.1% of science process skills have a direct effect by the Initial Setting (X) variable of the Investigation-Based Group Inquiry Model.
The Relationship between Taxation, Accounting and Legal Forms
Authors: Kollruss Thomas
Published: March 2021

Legal frameworks have an enormous influence on the concrete choice of legal form, especially in (multinational) groups of companies. For example, tax regulations and accounting standards directly influence the legal enterprise’s structure, including the shareholding structures. However, the tax burden must not be understood as a static or a fixed quantity determined in advance. This is because the design or choice of companies’ legal form can also be used as a tool to gain competitive advantages and optimise the tax burden or after-tax profit. Accordingly, the tax-optimising choice of legal form can be used as an instrument for tax planning and internal financing (reduction of tax payments and optimisation of the group tax rate). Therefore, for groups of companies and multinationals, the question that arises is how and within what limits can they make effective use of the cross-border tax rate differential, particularly through structuring their legal form. However, using cross-border tax advantages may be prevented by the controlled foreign corporation (CFC) taxation, called the Anti Tax Avoidance Directive (ATAD), which was introduced in all EU member states from 1 January 2019 onwards due to European law: Art. 7, 8 of Directive 2016/1164 to combat tax avoidance practices. In multinational companies, there is a tension between the tax-optimising choice of legal form, including the structuring of shareholdings, and CFC taxation. It is important to identify the CFC taxation requirements according to ATAD or the respective member state of residence and to avoid these requirements when structuring individual circumstances or investments. An important finding here is that the factual prerequisites for CFC taxation under ATAD are not aligned with the accounting rules, especially controlling interest and control participation. Finally, from an overall perspective, tax-optimised corporate groups’ structure or the legal architecture is not a static variable but an evolving system composed of tax-optimised sub-systems or subgroup structures. This connection between the choice of legal form, shareholding structure and the legal system, tax planning, and tax optimisation in multinational companies is analysed and evaluated based on the Austrian CFC taxation (Sec. 10a CITA) and the German CFC taxation (Sec. 7 FTTA). Furthermore, the implications for companies and society, and the legislator, are highlighted. The article also deals with the relationship between law and tax planning.

The Geographical Distribution of the Demotic Translations of the Epithet “Neos Philopatôr”
Authors: Uggetti Lorenzo
Published: March 2021

The epithet “god Neos Philopatôr” was used for the prince Ptolemy “Memphitês”, killed in 130 BC by his father Ptolemy VIII Euergetês II during the conflict against his mother Cleopatra II, but then introduced in the Ptolemaic dynastic cult before the amnesty decrees of 118 BC, as a sign of reconciliation. This Greek title led to different translations in Demotic, which depended on the geographical origin of the scribes.
