Το σχολείο είναι η πρώτη επαφή των παιδιών με το κοινωνικό σύνολο και η Φυσική Αγωγή είναι επί το πλείστο το μάθημα εκείνο που δημιουργεί στους μαθητές/τριες θετικά συναισθήματα. Ερευνητικά δεδομένα υποστηρίζουν ότι η άθληση δεν βελτιώνει μόνο τις φυσικές ικανότητες, αλλά καταφέρνει και ενισχύει τις ψυχολογικές και κοινωνικές δεξιότητες των παιδιών. Σκοπός της παρούσας έρευνας ήταν να μελετήσει την επίδραση ενός παρεμβατικού προγράμματος χορού στο μάθημα της Φυσικής Αγωγής, σε ψυχοκοινωνικές μεταβλητές μαθητών/τριών της Α/θμιας Εκπαίδευσης. Στην έρευνα συμμετείχαν 369 μαθητές και μαθήτριες από Α ́ έως και ΣΤ ́ τάξη Δημοτικών σχολείων (Μ.Ο= 8.57, Τ.Α= 1.7). Χωρίστηκαν σε τρεις ομάδες, την ομάδα παρέμβασης Α, η οποία κατά τη διάρκεια του μαθήματος της Φυσικής Αγωγής έκανε διάφορα είδη χορού, την ομάδα παρέμβασης Β, η οποία κατά τη διάρκεια του μαθήματος της Φυσικής Αγωγής, έκανε ελληνικό παραδοσιακό χορό και την ομάδα ελέγχου Γ, η οποία ακολούθησε το αναλυτικό πρόγραμμα κάνοντας αθλοπαιδιές. Το παρεμβατικό πρόγραμμα είχε διάρκεια συνολικά 4 μήνες. Οι μαθητές/τριες συμπλήρωσαν ερωτηματολόγιο πριν την εφαρμογή του προγράμματος όπου μετρήθηκε η υποκειμενική αίσθηση της ευχαρίστησης και τη ζωτικότητας που εισπράττουν από το μάθημα της Φυσικής Αγωγής, η ικανοποίηση των μαθητών/τριών από τον εαυτό τους, το σχολείο και τους φίλους τους, η διαχείριση των συναισθημάτων τους, η ενσυναίσθηση και οι διαπροσωπικές τους σχέσεις, η κοινωνική τους συμπεριφορά και το άγχος. Από τις τιμές στις μετρήσεις των αναλύσεων φάνηκε ότι οι μαθητές/τριες των ομάδων παρέμβασης επηρεάστηκαν θετικά από το συγκεκριμένο πρόγραμμα. Τα αποτελέσματα της έρευνας έδειξαν ότι ιδιαίτερα οι μαθητές/τριες της ομάδας παρέμβασης Α, η οποία έκανε διάφορα είδη χορού, παρουσίασαν αύξηση της ευχαρίστησης και της ζωτικότητάς τους, βελτίωση των κοινωνικών σχέσεων και της ικανοποίησης γενικότερα από τη ζωή τους, ενώ αντίθετα παρουσίασαν μείωση του άγχους και των κοινωνικών τους δυσκολιών. Συμπερασματικά, φάνηκε ότι ένα πρόγραμμα παρέμβασης στο μάθημα της σχολικής Φυσικής Αγωγής που εστιάζεται στο χορό, επηρεάζει θετικά διάφορες ψυχοκοινωνικές μεταβλητές μαθητών/τριών της Α/θμιας Εκπαίδευσης.

Environmental perceptions of global business travel by Swiss companies in the Zurich airport region
Authors: Echeverria Arrondo Ignacio , Wolfs Bert
Published: September 2021

Background: This article presents findings from research conducted before the coronavirus disease 2019 (COVID-19) pandemic on companies located in the Zurich airport region of Switzerland, regarding the needs for global business travel and its impacts.

Methods: The study involved a mixed methods approach. Five hypotheses were tested using inferential statistics on data obtained from pre-tested closed questions in a web-based survey. Deeper context was explored through an interview-based case-study conducted at a Swiss pharma company.

Results: Supporting alternative hypothesis 3 (Ha(3)), a significant positive relationship was found between travel frequency and business growth, F(1, 100) = 11.31, p = 0.0011. Supporting Ha(4), corporate culture had a significant positive relationship with business travel frequency (F(1, 100) = 15.50, p = 0.0002) and average trip length (F(1, 100) = 6.39, p = 0.01). And thirdly supporting Ha(5), corporate social responsibility had a significant relationship with global business travel (91%). Ho(2) and Ho(3) were accepted. The case study found that smart corporate travel policies and regulations should be instantiated to enhance our environment, which would also benefit employee wellbeing. Travel can be reduced significantly despite being demonstrated that physical co-presence is important for building trust. The case study suggests tools to support the monitoring and management of global business travel by organizations.

Conclusions: COVID-19 has impacted travel for business significantly, and future research will be necessary to assess its impact. The article explores the ongoing research in this area, and several relevant implications are proposed for future leaders. The case study found willingness to pay both corporate and individual green taxes, and a deficiency in corporate communication around the environment. Business travel is needed to build trust; however, it can be reduced.
Environmental screening for SARS-CoV-2 in long term care facilities: lessons from a pilot study
Authors: Kwiatkowska Rachel , Yaxley Nicola , Moore Ginny , Bennett Allan , Donati Matthew , Love Nicola , Vivancos Roberto , Hickman Matthew , Ready Derren R
Published: September 2021

Background: The SARS-CoV-2 pandemic has highlighted the risk of infection transmission in long-term care facilities (LTCF) and the vulnerability of resident populations. It is essential to understand the environmental spread of the virus and risk of indirect transmission to inform Infection Prevention and Control (IPC) measures in these settings.

Methods: Upon notification of SARS-CoV-2 outbreaks, LTCF within a local authority in the South West of England were approached to take part in this pilot study. Investigators visited to swab common touch-points and elevated ‘non-touch’ surfaces and samples were analysed for presence of SARS-CoV-2 genetic material (RNA). Data were collected regarding LTCF infrastructure, staff behaviours, clinical and epidemiological risk factors for infection (staff and residents), and IPC measures.

Criteria for success were: recruitment of three LTCF; detection of SARS-COV-2 RNA; variation in proportion of SARS-CoV-2 positive surfaces by sampling zone; potential to assess infection risk from SARS-CoV-2 positive surfaces.

Results: Three LTCFs were recruited, ranging in size and resident demographics. Outbreaks lasted 63, 50 and 30 days with resident attack rates of 53%, 40% and 8%, respectively. The proportion of sample sites on which SARS-CoV-2 was detected was highest in rooms occupied by infected residents and varied elsewhere in the LTCF, with low levels in a facility implementing enhanced IPC measures. The heterogeneity of settings and difficulty obtaining data made it difficult to assess association between environmental contamination and infection. Elevated surfaces were more likely to test positive for SARS-CoV-2 RNA than common touch-points.

Conclusions: SARS-CoV-2 RNA can be detected in a variety of LTCF outbreak settings. We identified variation in environmental spread which could be associated with implementation of IPC measures, though we were unable to assess the impact on infection risk. Sampling elevated surfaces could add to ongoing public health surveillance for SARS-CoV-2 and other airborne pathogens in LTCF.

DONNE CHE SI SACRIFICANO NELLA GRECIA ANTICA: ALCESTI.
Authors: Cerrato Daniele
Published: September 2021

Nella Grecia del V secolo a.C. era molto frequente che le donne venissero sacrificate in onore della patria. Polissena nell’Ecuba di Euripide, Ifigenia nell’Ifigenia in Aulide e Macaria negli Eraclidi sono tre esempi di vergini costrette al sacrificio. Un caso a parte è quello di Alcesti: il suo sacrificio non consiste solo nella distruzione della donna, ma della relazione che ha con suo marito: avviene lo sconvolgimento di un ordine coniugale.
Adaptando o teatro para a televisão: A Megera Domada em Malhação Sonhos
Authors: Luiz Tiago Marques
Published: September 2021

As obras de Shakespeare têm sido veiculadas nos mais variados suportes, começando pelo próprio palco até as mídias digitais, conquistando e cativando um vasto número de leitores. A relação entre televisão e teatro tem sido baseada na correspondência e apropriação da segunda mídia pela primeira. Alex Giostri (2018) define a dramaturgia como “a técnica dramática que estabelece os princípios de construção de uma obra literária com finalidades teatrais, cinematográficas ou televisivas”. Ampliando a conceituação, Giostri atesta que a dramaturgia tem como propósito despertar o interesse no espectador, por meio de uma narrativa bem articulada, seja ela no tempo presente, passado ou futuro, sem uma interferência na ação (GIOSTRI, 2018, p. 14).  Inserido no campo dos Estudos da Adaptação e dialogando com os Estudos de Televisão, este artigo pretende refletir sobre a transposição da dramaturgia cênica para a televisiva, dada a diferença e semelhança desses meios semióticos. Para melhor exposição de nossa reflexão, analisaremos brevemente a comédia shakespeariana A Megera Domada na versão televisiva no folhetim da Rede Globo Malhação: Sonhos, cujos personagens Pedro e Karina, representam as atitudes de seus precursores Petrúquio e Katarina, mas com uma nova roupagem – o universo adolescente.
A AVE, de Wlademir Dias-Pino, e “Homenaje a Wlademir Dias-Pino”, de Clemente Padín: relações ciberpoéticas
Authors: Pereira Vinicius Carvalho
Published: September 2021

No conjunto de experimentações da poesia visual com novas mídias, que grassa na América Latina desde meados do século XX, destacamos neste artigo dois marcos desse campo: A AVE, de Wlademir Dias-Pino, e “Homenaje a Wlademir Dias-Pino”, de Clemente Padín. Nas análises que ora apresentamos, discutimos como tais textos, de papel capital na história do Poema-processo como proposta artística, indagam, respectivamente, as materialidades analógica e digital que os constituem. Para tanto, tomamos os recursos poéticos de ambas as obras como dispositivos tecnológicos codificados tanto em linguagem verbal quanto em componentes procedimentais que devem ser executadas no ato da leitura. Nesse contexto, elegemos a metáfora de ciclos cibernéticos para discutir os modos como as máquinas poéticas de Dias-Pino e Padín operam trocando entre si imagens poéticas nos níveis dos códigos e dos metacódigos.
Cagliostro em l’affaire du collier de la reine: entre a história, a literatura e o cinema
Authors: Fonseca Maria Gabriella Flores Severo , Barbosa Sidney
Published: September 2021

Cagliostro (1743-1795) foi uma figura histórica envolvida na trama social conhecida como l’affaire du collier de la reine, ocorrida em 1785 na Corte de Luís XVI e de Maria Antonieta, retratada no romance histórico Le Collier de la reine (1850-1852) de Alexandre Dumas, Pai. Na narrativa, o autor francês dialoga com arquivos históricos a respeito do personagem e é bastante inventivo na sua caracterização, apresentando-o como um agente inoportuno de um episódio político considerado preparador da queda da Bastilha. O enigmático e influente Cagliostro, inventado por Dumas, tornou-se transficcional, sendo retomado no filme Black Magic/ Cagliostro (1949). Nessa obra, o personagem passou a transitar alterado e renovado, indo do texto ao filme parcial ou totalmente modificado, enriquecendo mais ainda o repertório adquirido.

Abstract. Heramza K, Barour C, Djabourabi A, Khati W, Bouallag C. 2021. Environmental parameters and diversity of diatoms in the Aïn Dalia dam, Northeast of Algeria. Biodiversitas 22: 3633-3644. Diatoms have long been used as biological indicators of the quality of aquatic environments due to their important capacity to respond to environmental change. As this flora has been very little studied in Algeria, the present study aimed to monitor the Spatio-temporal dynamics of diatoms at the Aïn Dalia dam (north-eastern of Algeria) and determine the main abiotic factors contributing to these variations from June 2017 to May 2018 in four selected stations. Our results showed that the waters of Aïn Dalia dam waters vary from moderately (St1 and St3) to significantly polluted (St2 and St4). They host the community of planktonic diatom flora composed of 72 species. The interspecific biodiversity was marked in summer and autumn (57 and 56 species respectively) and in the St4 station (52 species). In terms of abundance, more than 40% of the overall density was found in the St4 station and the fall period. Among the dominant genera, Cyclotella, Thalassiosira, Synedra and Navicula are found in moderately polluted waters, while Nitzschia, Melosira and Surirella in significantly polluted waters. Some environmental parameters, including nutrients (PO43-and NO2-), SM, temperature, dissolved oxygen, and pH played a key role in the functioning and evolution of this lake. Hence, these parameters demonstrated important fluctuations during our study and influenced directly the diatom distribution. These results showed that diatom assemblages are influenced by anthropogenic disturbances, and can be used as indicators of environmental quality.

Abstract. Biag RA, Alejandro GJD. Diversity, distribution, and conservation status of Rubiaceae species in Peñablanca Protected Landscape and Seascape, Luzon, Philippines. Biodiversitas 22: 3627-3636. Peñablanca Protected Landscape and Seascape (PPLS) is the largest protected area (PA) in the province of Cagayan, Luzon, Philippines. As part of the Sierra Madre Mountain Range and being contiguous with the Northern Sierra Madre Natural Park, there is no doubt that this PA would display species endemism and richness. Hence, botanical surveys through purposive sampling in seven barangays/districts were conducted in the PPLS to determine the species diversity and distribution of Rubiaceae. This study also aims to identify the endemic species and determine their conservation status. Forty-two species of Rubiaceae belonging to 19 genera and 13 tribes were documented in the current study. The most species-rich tribes are Spermacoceae (9 sp.), followed by Psychotrieae (7 sp.), Pavetteae (6 sp.), Naucleae (5 sp.), Ixoreae (4 sp.), Aleisantheae (2 sp.), Mussaendeae (2 sp.), and Vanguerieae (2 sp.). The rest of the tribes, i.e., Augusteae, Coffeeae, Gardenieae, Knoxieae, and Morindeae, are represented by a single species. Minanga, Nabbabalayan and Sisim harbor the most species. Results show that 19 Philippine endemic species are thriving in the PPLS. Of these, four are threatened species; one is near threatened, three being least concern, two as data deficient, and the rest were not evaluated.

Abstract. Ihsan M, Puspitarini RD, Afandhi A, Fernando I. 2021. Abundance and diversity of edaphic mites (Arachnida, Acari) under different forest management systems in Indonesia. Biodiversitas 22: 3685-3692. Edaphic mites play crucial roles in maintaining ecosystem services that are essential to human needs. However, the conversion of natural habitats followed by agricultural intensification may adversely affect edaphic mites. The objective of this study was to investigate the influence of different management systems on edaphic mite abundance, richness, and diversity in tropical rain forests in Indonesia. There were five forest management systems, which were as follows: secondary forest, production forest (pine monoculture), and three agroforestry systems (pine + coffee, mahogany + coffee, and mahogany + new cocoyam). We established a transect containing five research plots for each forest management system. Litter and soil from each plot were collected from December to March 2021. Temperature, relative humidity, and pH of litter and soil, as well as litter thickness, were measured. We found that edaphic mite abundance, richness, and diversity in the secondary forest were similar to managed forests. However, the aforementioned variables were significantly higher in “pine” systems than in “mahogany” systems. Our analysis evidenced positive correlations between litter thickness and edaphic mite abundance, richness, and diversity. Our findings may assist in selecting the appropriate forest management systems to rationalize the conversion of secondary forests to production forests and agroforestry.

Abstract. Choirunnisa JP, Widiyastuti Y, Sakya AT, Yunus A. 2021. Morphological characteristics and flavonoid accumulation of Echinacea purpurea cultivated at various salinity. Biodiversitas 22: 3716-3721. Purple coneflower (Echinacea purpurea (L.) Moench) is an introduced medicinal plant from North America. E. purpurea has high morphological characteristics on stems, leaves and flowers. This plant has not much cultivated as a raw material for traditional medicine in Indonesia due to not much information about flavonoid accumulation of E. purpurea in this country. The purpose of this research was to study morphological characteristics from three accessions of E. purpurea cultivated with various salinity and to select E. purpurea accessions that have high flavonoid accumulation. This study design using a factorial Completely Randomized Design (CRD). The first factor is 3 accessions of E. purpurea (E1; E2; E3). The second factor is 4 levels of CaCl2 (0 ppm; 2500 ppm; 5000 ppm; 10000 ppm). The study was conducted by observing the morphological characteristics of stems, leaves flowers, and herb extract and flavonoid accumulation were analyzed using SPSS. The results demonstrated that morphological characteristics are easy to observed on leaf shape and flower color. The highest herb extract with 10.043% and flavonoid accumulation with 0.510% were in accession 2 with the addition of  CaCl2 concentration of 10000 ppm. This study concludes that there are morphological characteristics of E. purpurea cultivated at various salinity and the highest CaCl2 concentration can increase with significance to herb extract and flavonoid accumulation.

Abstract. Husna, Tuheteru FD, Arif A. 2021. Arbuscular mycorrhizal fungi to enhance the growth of tropical endangered species Pterocarpus indicus and Pericopsis mooniana in post gold mine field in Southeast Sulawesi, Indonesia. Biodiversitas 22: 3844-3853. Gold mining activities contribute to the national economy, but have a serious impact on forest and environmental degradation and pose a threat to tree species in the tropics. Reforestation of post-gold mining with tropical legume tree species is threatened with extinction. Arbuscular mycorrhizal fungi are effective in conservation of endangered plants and restoration of degraded land. The objective of the study was to evaluate the effect of native AM Fungi inoculation on the growth of Pterocarpus indicus and Pericopsis mooniana in nurseries and post-gold mining fields. P. indicus and P. mooniana seedlings were inoculated with Glomus claroideum Schenk & Smith, Glomus coronatum Giovann., and mixed AMF (G. claroideum, G. coronatum). Uninoculated seedlings were used as control treatment, and they were maintained for 4 months under greenhouse conditions. After 4 months in greenhouse, seedlings were transferred to post-gold mine and planted for 4 months. The percentage of AMF colonization, plant growth, nutrient content and uptake of N, P, K, Fe, Mn were measured after 4 months both in the greenhouse and the field. The percentage of AMF colonization under greenhouse conditions in P. indicus and P. mooniana ranged 5.67-75.3% and 2.2-41.2%. All AMF colonization tended to have higher shoot height, leaf numbers and nodules, plant dry weight and N, P, K content under greenhouse conditions. Shoot height, stem diameter, leaf dry weight, N, P, K, Mn and Fe under field conditions had higher inoculated seedlings than control four months after planting. AMF could be used to conserve endangered tree species in post-gold mining reforestation in the tropics.

Abstract. Sadimantara GR, Yusuf DN, Febrianti E, Leomo S, Muhidin. 2021. The performance of agronomic traits, genetic variability, and correlation studies for yield and its components in some red rice (Oryza sativa) promising lines. Biodiversitas 22: 3994-4001. Improving a new variety commonly depends on the nature and magnitude of genetic variability and its utilization, followed by selection and evaluation before being released into new superior types. The present study aims to estimate the genetic variability and relation between yield and its related traits of the red rice promising lines. The experiment was arranged based on a randomized complete block design (RCBD) with three replications. Analysis of variance revealed significant differences among rice lines for 12 quantitative traits. The phenotypic coefficient of variation (PCV) value was higher than the genotypic coefficient of variation (GCV), indicating a negligible environmental influence in the phenotypic expression of traits. High heritability estimates coupled with high genetic advance were recorded for grain total per panicle and grain yield per hill. Grain yield observed a highly significant positive correlation with panicle length (0.63), percentage of filled grains (0.53), grain weight per panicle (0.54), and thousand-grain weight (0.52). It correlated negatively with days to 50% flowering (-0.61) and days to maturity (-0.48). The study indicated that panicle length, percentage of filled grains, grain weight per panicle, and thousand-grain weight are important yield-related traits and could be used for selection to improve the genetic potential of rice yield.

Abstract. Prabowo H, Rahardjo BT, Mudjiono G, Rizali A. 2021. Impact of habitat manipulation on the diversity and abundance of beneficial and pest arthropods in sugarcane ratoon. Biodiversitas 22: 4002-4010. Sugar production in Indonesia faces several challenges such as infestation of pests and diseases that lead to decline in sugarcane production and productivity. In order to overcome the loss of yields from the presence of pests, alternative new approaches are sought by solving of the problem that can have a sustainable impact by applying habitat manipulation. Habitat manipulation changes the diversity and density of arthropods populations in agro-ecosystem. In the concept of managing agroecosystems with habitat manipulation, it is hoped that the development of agro-ecosystem resilience against pest management will be expected to be suistainable. The results showed that there was an increase in the number of arthropods in the research area for 20 weeks after the management of agro-ecosystems through habitat manipulation. The arthropods in all the traps were dominated by Collembola, Diptera, Coleoptera, Aranea, and Hymenoptera. There were 44 genera that belong to predators and 8 species are belonging to parasitoids. The diversity index of Shannon-Wiener (H '), Simpson Dominance (C) and Species Evenness (E) was not significantly different between treatment and control, but habitat manipulation treatment was able to increase the number of detritivores, predators, parasitoids, and pollinators by 38.81; 43.88; 58.4; and 75.35%. The full role of arthropods in the food chain of the sugarcane ecosystem has been identified and efforts are needed to optimize the role of natural enemies in the agroecosystem to maintain ecosystem stability. Habitat manipulation can increase the number of beneficial insect populations in short run, but it might take time to increase their diversity in agroecosystem.

Abstract. Padjung R, Farid M, Musa Y, Anshori MF, Nur A, Masnenong A. 2021. Drought-adapted maize line based on morphophysiological selection index. Biodiversitas 22: 4028-4035. Synthetic line formation is an effort to increase maize productivity in drought-stressed areas. This process requires systematic selection in determining adaptability levels involving important secondary characters formulated in the selection index. Furthermore, the principal component index had been widely reported, both in normal and stressed conditions. The selection index development on morpho-physiological characters based on multivariate analysis was expected to increase drought stress tolerance and maize lines selection precision. Therefore, the purpose of this research was to form a selection index based on morpho-physiological characters and selecting synthetic lines adaptive under drought stress. This research was designed using a split-plot with 3 replications,  where the main plot consisted of normal and stressed irrigation, while the subplot was genotype consisting of 6 lines and 3 check varieties namely Bisma, Lamuru, and Sukamarga. Observations were performed on 18 morphological and 4 physiological characters, and the results showed that the selection index was formed based on multivariate analysis from 9 characters. Through index selection, Syn_2-2 (0.79), Syn_2-15 (0.85) and Syn_2-16 (0.97) were considered as drought stress adaptive lines. Therefore, the 3 lines can be recommended in the synthetic variety release process.

Abstract. Nasrika E, Retnonongsih A. 2021. Inter Simple Sequence Repeat molecular markers to reveal the genetic diversity of superior durian of Gunungpati, Semarang, Indonesia. Biodiversitas 22: 4054-4059. Kalimantan is the center of many tropical fruits, including durian. One of the edible durians and favorited by many is Durio zibethinus, which has many superior varieties. Almost all regions in Indonesia have superior durian varieties; for example, superior durian Gunungpati from Gunungpati Sub-district, the center for producing durian in Semarang City, Central Java, Indonesia. ISSR analysis was carried out to reveal the genetic diversity of the superior durian Gunungpati. DNA isolation of 16 superior durians used the modified CTAB method. The genomic DNA was amplified using 10 ISSR primers and then electrophoresed using 2% agarose gel. Data were analyzed using NTSYS PC version 2.02. The resulting allele has a relative size of 220 bp-1800 bp, with 87.9% are polymorphic. The similarity coefficient of 16 varieties was ranged between 0.54-0.88. All the superior durian varieties examined were different accessions so that each variety has the potential to be registered as a new variety of superior Indonesian durian. Specific alleles are found in G1, G3, G7, G8, and G13, which can be an identity of these varieties.

A non-invasive diagnostic tool to assess remodeling of the lung airways caused by disease is currently missing in the clinic. Measuring key features such as airway smooth muscle (ASM) thickness would increase the ability to improve diagnosis and enable treatment evaluation. In this research, polarization-sensitive optical coherence tomography (PS-OCT) has been used to image a total of 24 airways from two healthy lungs and four end-stage diseased lungs ex vivo, including fibrotic sarcoidosis, chronic obstructive pulmonary disease (COPD), fibrotic hypersensitivity pneumonitis, and cystic fibrosis. In the diseased lungs, except COPD, the amount of measured airway smooth muscle was increased. In COPD, airway smooth muscle could not be distinguished from surrounding collagen. COPD lungs showed increased alveolar size. 3D pullbacks in the same lumen provided reproducible assessment of airway smooth muscle (ASM). Image features such as thickened ASM and size/presence of alveoli were recognized in histology. The results of this study are preliminary and must be confirmed with further ex vivo and in vivo studies. PS-OCT is applicable for in vivo assessment of peribronchial and peribronchiolar lung structures and may become a valuable tool for diagnosis in pulmonology.

Published: September 2021

Im Kontext der vorliegenden Forschungsarbeit wird der Beitrag externer Enterprise-Resource-Planning-Dienstleister (ERP) im deutschsprachigen Raum sowie eine Möglichkeit zur Service-Angebotsdifferenzierung untersucht. Hierbei steht der Schweizer Produktionsstandort der Maschinen‑, Elektro- und Metall-Industrie (MEM-Industrie) im Fokus. Gegenstand der Studie ist die Frage nach dem Beitrag externer Dienstleister während der Phasen der ERP-Implementierung und dem anschließenden Betrieb. Das Ergebnis ergänzt die bisherige Literatur zu kritischen Erfolgsfaktoren, welche bisher überwiegend im Zusammenhang mit dem Erfolg von ERP-Implementierungen im anwenderorientierten Kontext von Unternehmen untersucht wurde. Basierend auf einer Umfrage mit 59 Unternehmen, ermöglicht die vorliegende Arbeit die erbrachten Beiträge der ERP-Dienstleister in Verbindung mit den wichtigsten Erfolgsfaktoren einer ERP-Implementierung zu beurteilen. Unternehmen, die ein ERP-System etablierter Anbieter (z. B. SAP) einsetzen, sehen in der Implementierung einen höheren Nutzen in der Zusammenarbeit mit einem externen Dienstleister als Unternehmen, die spezifische und wenig umfassende Systeme im Einsatz haben. Den größten Mehrwert durch den Beitrag externer ERP-Dienstleister sehen die Unternehmen in der Qualitätsverbesserung bei der Implementierung sowie in der erhöhten Stabilität der IT-Infrastruktur. Der Beitrag zur gesteigerten Qualitätsverbesserung durch eine konsequente Datendurchgängigkeit kann als Ausgangspunkt zur Service-Angebotsdifferenzierung der ERP-Dienstleister gesehen werden. ERP-Systeme mit der Funktion eines Integrations-Hubs tragen somit zur nachhaltigen Qualitätsverbesserung bei und ermöglichen dadurch diverse Service-Differenzierungen.
Exploring barriers for trachomatous trichiasis surgery implementation in gamo zone, Southern Ethiopia
Authors: Churko Chuchu , Asfaw Mekuria Asnakew , Zerdo Zerihun
Published: September 2021

Background

Trachomatous trichiasis is the leading infectious cause of blindness worldwide. The World Health Organization recommends eyelid surgery to reduce the risk of visual impairment from trichiasis. Unfortunately, the number of cases operated has grown less than expected. An understanding of barriers is fundamental for instituting measures to increase surgical uptake. Therefore, the aim of this study was to explore barriers of TT surgery implementation.

Methods

A qualitative study design was employed in December 2019. Purposive sampling technique was used to select three districts from Gamo zone, Southern Ethiopia. We conducted 9 FGDs and 12 in-depth interviews. Data was collected by audio tape recorder in Amharic and Gamogna languages and then transcribed to English language. The recorded interviews and focus group discussions were transcribed to verbatim (written text) and thematic analysis was done manually and reported accordingly.

Findings

we explored a number of barriers that hindered implementation of trichiasis surgery. The recurrence of trichiasis after surgery was the main challenges faced by operated individuals. The other barriers reported are negative perception towards trichiasis surgery, lack of logistic and supplies, transportation access problem for remote communities, inadequate trained health professional, less commitment from higher officials, lack of interest of integrated eye care workers due to incentive issues, believes of patients waiting supernatural power for healing service and carelessness of patients to undertake operation.

Conclusion and recommendation

Post-surgical trichiasis, lack of commitment from government officials and negative perception of patients towards the disease were considered as the reported barriers for implementation of trachomatous trichiasis. Closely supervising the integrated eye care workers would be the first task for district health offices to increase the uptake and improve the quality of service. Logistics and supplies should be made available and adequate to address all affected people in the community.
Brain water as a function of age and weight in normal rats
Authors: Gottschalk Allan , Scafidi Susanna , Toung Thomas J. K.
Published: September 2021

Rats are frequently used for studying water content of normal and injured brain, as well as changes in response to various osmotherapeutic regimens. Magnetic resonance imaging in humans has shown that brain water content declines with age as a result of progressive myelination and other processes. The purpose of this study was to quantify changes in brain water content during rat development and aging. Brain water content was measured by standard techniques in 129 normal male Sprague-Dawley rats that ranged in age (weight) from 13 to 149 days (18 to 759 g). Overall, the results demonstrated a decrease in water content from 85.59% to 76.56% with increasing age (weight). Nonlinear allometric functions relating brain water to age and weight were determined. These findings provide age-related context for prior rat studies of brain water, emphasize the importance of using similarly aged controls in studies of brain water, and indicate that age-related changes in brain water content are not specific to humans.
Refractive changes of a new asymmetric intracorneal ring segment with variable thickness and base width: A 2D finite-element model
Authors: García de Oteyza Gonzalo , Álvarez de Toledo Juan , Barraquer Rafael I. , Kling Sabine
Published: September 2021

Purpose

To evaluate the local geometric effects of a unilateral intrastromal ring segment with a combined variation of ring thickness and base width in a finite element simulation, and to compare it against the isolated effect of thickness or base width variation alone.

Methods

A two-dimensional finite-element model of a transversely isotropic cornea was created assuming either axisymmetric stress or plane strain condition. The model geometry was composed of a three-layered corneal tissue (epithelium, anterior and posterior stroma) fixed at the limbus. The implantation of a triangular-shape asymmetric ring segment with varying ring thickness (150 to 300 μm) and base width (600 to 800 μm) was simulated. Also, changes induced by thickness or base width alone were studied and compared their combined effect in the asymmetric ring segment. Geometrical deformation of the simulated cornea and sagittal curvature were the main parameters of study.

Results

Increasing ring thickness and base width along the arc of the asymmetric ring segment produced a more pronounced flattening in this part of the ring. The asymmetric design did find a good balance between maximizing corneal flattening at one end and minimizing it at the other end, compared to the isolated effect of ring thickness and width. Ring thickness was the most robust parameter in flattening both, the central and peripheral cornea.

Conclusion

The finite-element model permitted a theoretical study of corneal deformation undergoing implantation of realistic and hypothetical ring geometries. Intracorneal asymmetric ring segments with varying thickness and base width can be a good alternative in corneas with asymmetric keratoconus phenotypes.

Authors: Malik Asmara , Malik Jahanzeb , Ishaq Uzma
Published: September 2021

Objective

Acceptance of the COVID-19 vaccine will impart a pivotal role in eradicating the virus. In Pakistan, health care workers (HCWs) are the first group to receive vaccination. This survey aimed at the level of acceptance to the COVID-19 vaccine and predictors of non-acceptance in HCWs.

Method

This was a cross-sectional study design and data were collected through 3rd December 2020 and February 14th, 2021. An English questionnaire was distributed through social media platforms and administration of affiliate hospitals along with snowball sampling for private hospitals.

Results

Out of 5,237 responses, 3,679 (70.2%) accepted COVID-19 vaccination and 1,284 (24.5%) wanted to delay until more data was available. Only 5.2% of HCWs rejected being vaccinated. Vaccine acceptance was more in young (76%) and female gender (63.3%) who worked in a tertiary care hospital (51.2%) and were direct patient care providers (61.3%). The reason for rejection in females was doubtful vaccine effectiveness (31.48%) while males rejected due to prior COVID-19 exposure (42.19%) and side effect profile of the vaccine (33.17%). Logistic regression analysis demonstrated age between 51–60 years, female gender, Pashtuns, those working in the specialty of medicine and allied, taking direct care of COVID-19 patients, higher education, and prior COVID-19 infection as the predictors for acceptance or rejection of COVID-19 vaccine.

Conclusion

In conclusion, this survey suggests that early on in a vaccination drive, majority of the HCWs in Pakistan are willing to be vaccinated and only a small number of participants would actually reject being vaccinated.
From COVID-19 to COVID-666: Quasi-religious mentality and ideologies in Nigerian coronavirus pandemic discourse
Authors: Chimuanya Lily , Igwebuike Ebuka Elias
Published: September 2021

In response to the global outbreak of the COVID-19 pandemic, different religious-immune conspiracy theories emerged to explain the increasing scary situation in Nigeria. Emerging multifarious narratives of the contagion, which are embedded in peculiar Nigerian socio-religiosity and religious economy, reconstructed the discourses into two complexities: corona disease is an invention of the devil and other dark evil forces, and corona disease is a sign of the end of times. The obvious fabrications escalated uncertainties surrounding the pandemic as well as generated anxiety and fears among potential believers who sermonize spiritual vigilance for the ‘final battle and journey’. Drawing insights from critical discourse analysis, moral panic and frame theory, this study explores discursive means through which the pandemic is represented and reconstructed as long-awaited ‘doomsday’ warning in Nigerian online communities. Findings reveal instances of varying descriptive names, lexical derivations and discursive frames that reflect counter belief and quasi-religious ideologies. The study argues that complex religious doctrines rooted in antichrist or mark of the beast view, socio-religious ideologies of dominionism and overcommernism, cultural and personal linguistic processes have all contributed in shaping and institutionalizing the viral ‘apocalyptic’ world-view of the outbreak.

In this paper, I discuss the social structure of modern capitalist society in a new conception based on the theory of institutional sociology. In the first part of the paper, I briefly outline the social structure of modern capitalist society. Taking social relations into account in terms of certain types of social capital and social relationships, I differentiate the following social classes in the modern capitalist society: (1) authority class, (2) strong tolerated class, (3) supported class, (4) medial tolerated class, (5) patronized class, (6) restricted class, (7) less weak tolerated class, (8) less exposed class, (9) very weak tolerated class and (10) very exposed class. In the second part of the paper, I analyse the social structure or the social classes composing the social structure in more detail. In the third part, I point out further aspects that ought to be considered in the empirical research of the social structure of capitalist society
The Effectiveness of Giving Plant PGPR Rhizosphere Bamboo on Cocoa Seeds Germination at The Nursery Level
Authors: Hardiansyah Muhammad Yusril , Musa Yunus , Jaya Abdul Mollah
Published: September 2021

The low productivity of cocoa plantations in Indonesia is partly due to the low quality of seeds, which refers to the impeded growth of cultivated cocoa nurseries. Seed is the initial growth of plants so the importance of giving special treatment to seeds will refer to better seed growth. Provision of Plant Growth Promoting Rhizobacteria (PGPR) microbes can produce indoleacetic acid (IAA) in plants to improve the quality of plant growth. This study aims to determine the effectiveness of the provision of Plant Growth Promoting Rhizobacteria bamboo rhizosphere against cocoa seed germination. The study was carried out in the farmer group garden, Gantarangkeke District, Bantaeng. This study was arranged in the form of a two-factor factorial design (F2F) in a randomized block design (RBD). The use of cocoa seed type as the first factor consisted of GTB (Gantarangkeke Bantaeng) local cocoa seed and MCC 01 cocoa seed and seed immersion treatment at PGPR rhizosphere bamboo concentration as the second factor consisting of 0% (control) concentration, 5%, 10 % and 15%. The results obtained indicate that administration of seeds with bamboo rhizosphere PGPR affects the germination (100.00%), the speed of seed growth (7.14%/etmal), as well as on abnormal seeds (10.00%). So that the provision of bamboo rhizosphere PGPR on cocoa seeds has an effective influence on seed germination and cocoa seedling development.

Medicinal plants usage in traditional medicine has risen over the years. Musa paradisiaca has been reported that it possesses various therapeutic efficacies. This study is aimed at evaluating the effect of parts of the ethanol fruit extracts of Musa paradisiaca on haematological indices and serum liver enzymes. Thirty Wistar rats were grouped into five groups of six animals each which were administered 200 mg/kg and 400 mg/kg of Musa paradisiac fruit (MPF) pulp extract or peel extract. Haematological indices and liver enzymes were assayed for at the end of the 14-days experimental period. MPF pulp and MPF peel at 400 mg/kg showed a significant (P<0.05) increase in red cell count and haematocrit level as compared to the control. There was a non-significant (P>0.05) increase in haemoglobin concentration in the treated rats as compared to the control. There was also a non-significant (P>0.05) change in AST, ALT, and ALP level of the treated rats as compared to the control. Fruit pulp and peel of Musa paradisiaca improve erythrocytes count and haematocrit level, and they may not be associated with liver toxicity.
