Vitis shizishanensis, a new species of the grape genus from Hubei province, China
Authors: Ma Zhi-Yao , Wen Jun , Fu Qiang , Liu Xiu-Qun
Published: November 2021

Vitis shizishanensis (Vitaceae), a new species from Hubei, China, is described and illustrated. It is morphologically similar to V. flexuosa and V. bryoniifolia, but differs in leaf lobing and pubescence. It can be easily distinguished from the two species based on its glabrous or with very sparse arachnoid tomentum on the abaxial mature leaf surface, and its unlobed to 3–7 lobed leaves. A detailed description, along with photographs for the new species, and a table for morphological comparisons with similar Vitis species, are also provided.
La politique française d’innovation
Authors: Delaunay Arnaud , Catoire Paul
Published: November 2021

Légitimée par la théorie économique contemporaine, la politique d’innovation est un axe central des politiques économiques actuelles pour augmenter les gains de productivité et la compétitivité hors-coûts, développer de nouveaux services et secteurs et accélérer le renouvellement du tissu économique. Si elle s’appuie en France sur un certain nombre d’outils fiscaux, financiers et normatifs bien établis, elle fait l’objet d’ajustements réguliers pour conforter son efficacité, dans un contexte marqué par le dynamisme d’autres pays en la matière. Depuis 2018, l’accent est à cet égard particulièrement porté sur l’innovation de rupture, le soutien réaffirmé et modernisé aux marchés et technologies de demain et l’importance donnée aux jeunes entreprises innovantes ( start-ups et scale-ups ).
Ordre et désordre dans l’Église catholique
Authors: Bazantay Christian
Published: November 2021

Coup de tonnerre, scandale infiltré », les abus sexuels vont obliger l’Eglise catholique à sortir de son immobilisme séculaire. La coexistence de deux droits, celui du Vatican, institution religieuse mais aussi État indépendant et celui de la Cité est-elle possible ? N’y a-t-il pas un risque de confusion dans la compréhension et la mise en œuvre des deux droits ? Cette dualité permet-elle aux membres de l’Eglise d’être des citoyens comme les autres ? Quelles conséquences ces scandales peuvent-ils avoir sur l’organisation de l’Eglise, le recrutement et la formation de son clergé ? Ce désordre va-t-il conduire à une évolution du dogme ?
Au nom de qui parlent-ils ?
Authors: Noël Jean-François
Published: November 2021

L’abuseur a-t-il repéré dans sa victime une défaillance ? L’emprise est plutôt à entendre comme un conflit d’idéal qui pousse le disciple à faire du maître l’interprète de la volonté de Dieu à son égard. En captant pour lui cette force, il prive le disciple d’entendre sa propre conscience, et ainsi entravé, le disciple ne peut plus faire jouer les différentes instances qui remanient la relation aux idéaux. Je propose d’ajouter aux deux premières moi-idéal, idéal du moi, l’instance de l’idéal du je, auquel la victime n’a plus accès. L’idéal du je est cette instance interne qui permet au sujet de remanier les idéaux, et non d’y renoncer, non plus de l’intérieur à partir du moi, mais de l’extérieur par une altérité qui vient interroger le je du sujet. Ceux qui se réclament de parler au nom de Dieu ne parlent qu’au nom de leur moi-idéal. D’où leur imposture meurtrière.
La solitude d’Isaac : séduction et vulnérabilité
Authors: Razon Laure
Published: November 2021

Nous assistons actuellement à une levée du silence concernant les abus sexuels par personne ayant autorité. Dans ce cadre-là nous avons mené des entretiens de recherche auprès de victimes. Nous présentons dans cet article l’analyse du témoignage d’Antonin abusé durant son adolescence par un « célibataire consacré » tel qu’il le nomme, dirigeant une communauté religieuse. Afin de mieux saisir les enjeux de l’abus, nous développons au préalable d’un point de vue théorique, la notion de séduction afin de mieux l’articuler avec celle de vulnérabilité.

Authors: Chang Xiaoyuan , Shi Junping
Published: November 2021

The bistable dynamics of a modified Nicholson's blowflies delay differential equation with Allee effect is analyzed. The stability and basins of attraction of multiple equilibria are studied by using Lyapunov-LaSalle invariance principle. The existence of multiple periodic solutions are shown using local and global Hopf bifurcations near positive equilibria, and these solutions generate long transient oscillatory patterns and asymptotic stable oscillatory patterns.

This study aimed to formulate sodium lauryl sulfate cross-linked chitosan beads and sodium alginate-chitosan films for designing a dressing that would shorten the healing time of skin wounds. Teucrium polium extract-loaded chitosan-sodium lauryl sulfate beads (CH-SLS) and chitosan-alginate (CH-ALG) films were prepared and characterized by using Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) analysis, and scanning electron microscopy (SEM). The swelling properties of the CH-SLS beads were also analyzed in a water solution. The obtained Teucrium polium extract-loaded CH-SLS beads and CH-ALG films (TBF) were further incorporated into the commercial adhesive dressing. This TBF wound dressing was then investigated for evaluation of its wound healing potential in the mice using the excision wound model. Healing was assessed by the macroscopic appearance and the rate of wound contraction during 8 days. On day 4, the TBF-treated wounds exhibited 98% reduction in the wound area when they were compared with healing ointment, elastic adhesive dressing, and untreated wounds which were exhibited 63%, 43%, and 32%, respectively. Furthermore, the application of TBF dressing reduced skin wound rank scores and increased the percentage of wounds contraction. These results demonstrate that TBF dressing improves considerably the healing rate and the macroscopic wound appearance at a short delay and this application may have therapeutic benefits in wound healing.
Protection Granted by Women: Between Law and Literature
Authors: Webb Peter
Published: November 2021

Grants of protection in pre‑Islamic Arabia were often connected to expressions of status and power. This paper evaluates the gendered aspects of protection to explore how Arabic literature viewed grants of protection by women. The issue was recorded in various guises: jurists debated the issue on a theoretical level, historians included relevant stories in the Prophet’s biography, and literature preserves other episodes from pre‑ and early‑Islamic‑era Arabia. While jurists generally permitted women to grant protection, literary works took an opposite track, and employed the trope of women’s acts of protecting to denigrate male characters. A cross‑genre analysis of women protectors reveals intriguing aspects about the status of women and the nature of fact and fiction in Arabic literature about the Arabian past.
Commendation in the Umayyad and Early Abbasid Period as Described in the Futūḥ al‑Buldān of al‑Balāḏurī
Authors: Kennedy Hugh N.
Published: November 2021

This paper examines ties of dependency in the Umayyad and early Abbasid period though the evidence from al-Balāḏurī’s Futūḥ al-Buldān. It argues (contra Cahen) that ilǧāʾ arrangements were often based on mutual self-interest rather than the needs of an oppressive elite. The variety of the arrangements explored in this paper gives an interesting insight into the different sorts of triangular relationships between the state (sulṭān), the powerful and the farmers.
Ressusciter l’archive. Reconstruction et histoire d’une lettre mamelouke pour le sultan du Takrūr (1440)
Authors: Dewière Rémi
Published: November 2021

Cet article vise à étudier la matérialité des relations diplomatiques entre l’Égypte mamelouke et les sultanats du Mali et du Borno, en reconstituant une lettre diplomatique mamelouke de 1440 aujourd’hui disparue. À l’aide du dessin assisté par ordinateur et des manuels de chancellerie mamelouke du xve siècle, il est possible de reconstituer une pseudo-lettre mamelouke à partir de la copie d’une lettre autorisant la venue au Caire du sultan du « Takrūr » pour le pèlerinage à La Mecque. La reproduction d’un artefact de pouvoir mamelouk à destination des souverains islamiques du Sahel permet de mettre à l’épreuve les normes de chancellerie énoncées par les secrétaires mamelouks sur un texte privé de ses marques de validation. Surtout, l’analyse du résultat permet de requestionner le rôle matériel des lettres dans les échanges diplomatiques transsahariens, dans le contexte de la diplomatie du ḥaǧǧ des sultans sahéliens et des circulations matérielles autour de l’écrit de part et d’autre du Sahara.
Living Together in Changing Iran. Pahlavi Documents on Arabs and Christians in Early Islamic Times
Authors: Weber Dieter
Published: November 2021

In this contribution original Pahlavi documents of clearly Zoroastrian provenance from the 7th and early 8th centuries are presented showing direct or indirect connections with increasing Arabic dominance in Iran. There are two groups of documents: 1. documents of the so‑called “Pahlavi Archive”, coming from the region west and south of Qom; 2. the documents from Tabarestān in Northern Iran, i.e. the region of modern Rūdbār on the river Sefīd, dealing mostly with juridical matters. The so-called “Pahlavi Archive” comprises economic documents as well as letters mostly from the second half of the 7th century and are housed in Berlin and Berkeley (about 300 items); there are also some scattered documents in Los Angeles and in private hands, probably in Iran. Though most of the documents in question are of economic content (they refer to daily life) they sometimes give hints at religious facts, taxes and measurements (Iranian and Arabic). Religion is explicitly referred to in a letter on wine growing where we learn of a regular payment for “prosperity” ~ “protection” of the religion (i.e. the Zoroastrian religion). The documents from Tabarestān, again clearly Zoroastrian, show no connections to Arabic matters but mention a Nestorian community.
Food Safety Audits
Authors: Siwach Ruby
Published: November 2021

Food safety has gained global attention due to rising issues of food-borne illnesses, adulteration, and increased consumer awareness about food safety worldwide. It is a challenge for the governments and the food industry itself to maintain food safety throughout the food and supply chain. There are several systems and processes adopted by various countries to ensure food safety, and the food safety audits are one of the indispensable tools to achieve the goals of food quality and safety. Rising trends of consuming processed foods, eating out in restaurants and cafes, home deliveries of food from outside worldwide have made the auditing process very essential to ensure that the food products are being manufactured, stored, and sold in compliance with national and international standards. This chapter aims at providing an overview of the food audit processes, scope, importance, challenges, and future trends.

Authors: Abdul Mutalib Noor Azira , Abdul Rahim Noor Aniza , Ungku Zainal Abidin Ungku Fatimah
Published: November 2021

Food poisoning cases in Malaysia showed an increasing trend every year where 496 episodes were reported in 2018 as compared to 401 episodes in the same week of the year 2017. Bacillus cereus is one of the foodborne pathogens related to food poisoning cases in Malaysia. The main cause for the outbreak of B. cereus is the unregulated temperature during holding time. This study was conducted to detect the presence of aerobic bacteria and B. cereus present in ready-to-eat food in Northern Perak. A total of 83 food samples were collected and analyzed for the microbial count. The result shows that aerobic bacteria and B. cereus were detected in 28% of the samples. B. cereus count in food samples tested ranged from 100 cfu/g to 42000 cfu/g, whereas the aerobic bacteria recorded a range of 500 cfu/g to 2100000 cfu/g. The highest percentage of B. cereus was found in rice-based food, followed by meat, poultry, and gravy dishes. Positive colonies of B. cereus were further tested for anti-microbial resistance profile. Most B. cereus isolates showed resistance to tetracycline and clindamycin.
Influence of the ECAP Tool Channel Geometry on the Structure and Properties of Al-3%Mg Aluminium Alloy
Authors: Snopiński Przemysław
Published: November 2021

In this study, commercial Al-3%Mg aluminium alloy was subjected to ECAP processing using two different ECAP die configurations. The first one – conventional and the second one modified in which a part of the exit channel in the ECAP die, causes twist deformation, to impose extra shear strains to the sample. The local changes in microstructure were characterized by Light Microscopy, SEM equipped with an EBSD facility and TEM. Mechanical properties of the ECAP processed samples were compared based on hardness measurement. The results showed that when ECAP with modified die, the greater grain and crystalline refinement is possible. The microstructures exhibit high dislocation density within subgrains with non-equilibrium and Moiré boundaries. Moreover, the mechanical examinations display a significant improvement in hardness and calculated yield strength when the ECAP process is conducted using a modified die.

Published: November 2021

Background: To evaluate retinal morphological and vascular parameters in patients recently diagnosed with obstructive sleep apnea syndrome (OSAS) and determine the correlation between retinal vascular density and the severity of OSAS.Methods: We performed a retrospective study on the retinal vasculature of patients with OSAS and age-match healthy controls. OSAS was confirmed by full-night cardiorespiratory polygraphy. Patients were divided into three groups according to disease severity given by apnea-hypopnea index (AHI) i.e., mild, moderate or severe. Retinal thicknesses and vascular density were compared between groups, for both the macula and optic disc. Correlation between vascular density and clinical features were also assessed.Results: The study included 30 eyes of patients with OSAS and 12 controls. No differences were found regarding retinal thickness in both the macula and the optic disc between OSAS patients and controls. In contrast significant differences were found in the peripapillary vessel density between groups versus control patients. The greatest difference being between severe OSAS and controls (49.4% ± 2.1 versus 40.4% ± 4.2 respectively, p=0.01). Peripapillary vessel density was found to significantly and negatively correlate with AHI (p=0.02; r= -0.74) and directly correlate with the lowest percutaneous oxygen saturation (p=0.02; r= 0.58).Conclusions: This study indicates that OSAS is associated with retinal microvasculature impairment, that seems to mainly affect the optic disc. This suggests that microvascular damage increases with the increasing severity of OSAS. As such prospective trials are needed to clarify if this vascular peripapillary damage precedes glaucomatous optic neuropathy in OSAS patients.

Published: November 2021

Background: Honey has been used in medicine since ancient times. Limited reports are available to indicate its antibacterial, antiviral, and antidiarrheal properties. This study aimed to determine the effect of honey on acute diarrhea in children.Methods: This randomized clinical trial included 80 children with acute diarrhea. Forty children received honey and zinc gluconate (trial group) and 40 received only zinc gluconate (control group). After treatment, vomiting/diarrhea duration, the recovery time, and the duration of hospitalization were compared between the groups.Results: Among the 40 children in the trial group, 19 were male and 21 were female. In the control group, 25 children were male and 15 female (P=0.26). After initiating treatment, the duration of diarrhea, recovery time, and the duration of hospitalization was significantly shorter in the trial group than in the control group (P<0.05).Conclusion: This study showed that honey with zinc gluconate reduces the duration of diarrhea, accelerates the recovery time, and shortens the duration of hospitalization.

A Case of Pacemaker Associated Aspergillus fumigatus Endocarditis
Authors: Ray Ujjwayini , Dutta Soma , Khan Aftab
Published: November 2021

The use of cardiovascular implantable electronic devices (CIED) is associated with improved quality of life and decreased fatal outcomes in patients with cardiac dysfunctions. As with all foreign devices that are inserted or implanted in the body, CIED also carries the risk of device-related infections. Infections account for <2% of the complications associated with CIED, and only about 2% of these are secondary to a fungal pathogen. The first case of Aspergillus endocarditis secondary to a transvenous pacing lead was reported in the 1980s, and a limited number of cases have been documented in the literature since then. Aspergillus endocarditis is a highly fatal disease and establishing the diagnosis sufficiently early is challenging. We here report a case of Aspergillus endocarditis secondary to permanent pacemaker insertion which was successfully treated following the establishment of the diagnosis using imaging studies and galactomannan assay.
Thrombocytopenia in Malaria
Authors: Karunaratna Sumudu , Ranaweera Dewanee , Vitharana Harshini , Ranaweera Prasad , Mendis Kamini , Fernando Deepika
Published: November 2021

Introduction:

Fever and thrombocytopenia, often presenting features of malaria, are also the hallmarks of dengue infections. This study examines the degree and duration of thrombocytopenia in imported malaria infections in Sri Lanka and the extent to which this could provide a false trail in favor of a dengue diagnosis.

Methods:

The data of all confirmed malaria cases reported in Sri Lanka from 2017 to 2019 were extracted from the national malaria database. These included detailed histories, the time to malaria diagnosis, platelet counts, and in 2019, the trail of diagnostic procedures.

Results:

Over the 3 years, 158 malaria cases (157 imported and one introduced) were reported. Platelet counts were available in 90.5% (n = 143) of patients among whom 86% (n = 123) showed a thrombocytopenia (<150,000 cells/μl) and in nearly a third (n = 52) a severe thrombocytopenia (<50,000 cells/μl). Only 30% of patients (n = 48) were diagnosed with malaria within 3 days of the onset of symptoms, while in 37% (n = 58) it took 7 or more days. Platelet counts where significantly higher in patients who had symptoms for 7 days or more compared to those who had symptoms for <7 days (χ2 = 6.888, P = 0.009). Dengue fever was suspected first in 30% (n = 16) of the total malaria patients reported in 2019.

Conclusions:

Low platelet counts could delay suspecting and testing for malaria. Eliciting a history of travel to a malaria-endemic country could provide an important and discerning clue to suspect and test for malaria in such patients.

Published: November 2021

La inclusión es un elemento fundamental de la práctica escolar. Sin embargo, los efectos de la pandemia COVID-19 en docentes y directivos que implementan prácticas inclusivas, como los miembros del Programa de Integración Escolar (PIE) en Chile, no han sido sondeados en profundidad. Este estudio utilizó el Análisis de Redes Sociales (ARS) para examinar patrones de interacción colaborativa de profesionales de la educación en una escuela chilena y determinar los papeles de integrantes del PIE durante la pandemia. Los resultados muestran que los profesionales de la educación del PIE tienen un rol preponderante, aunque ambivalente, dentro de las redes. Si bien la pandemia no afectó su trabajo tradicional, sí resaltó sus papeles por sobre las jefaturas tradicionales, donde la inclusión es clave para contrarrestar la inequidad exacerbada por el contexto. Esta evidencia puede contribuir al desarrollo de prácticas colaborativas atingentes a desafíos educativos durante y posteriores a la emergencia sanitaria.

A theorem on the multiplicity of the singular spectrum of a general Anderson-type Hamiltonian
Authors: Dolai Dhriti Ranjan , Mallick Anish
Published: November 2021

In this work, we study the multiplicity of the singular spectrum for operators of the form

A^\omega=A+\sum_{n}\omega_n C_n

on a separable Hilbert space

\mathcal{H}

, where

A

is a self-adjoint operator and

\{C_n\}_{n}

is a countable collection of non-negative finite-rank operators. When

\{\omega_n\}_n

are independent real random variables with absolutely continuous distributions, we show that the multiplicity of the singular spectrum is almost surely bounded above by the maximum algebraic multiplicity of the eigenvalues of the operator

\sqrt{C_n}(A^\omega-z)^{-1}\sqrt{C_n}

for all

n

and almost all

(z,\omega)

. The result is optimal in the sense that there are operators for which the bound is achieved. We also provide an effective bound on the multiplicity of the singular spectrum for some special cases.
China: capital flight or renminbi internationalization?
Authors: van Noije Paulo , De Conti Bruno , Zucker-Marques Marina
Published: November 2021

During 2014–2016, many analysts have claimed the occurrence of a capital flight in China due to the reduction of the country's foreign reserves by over US$800 billion. This paper aims therefore to answer the question: did China really undergo a capital flight in this period? Its methodology includes a detailed analysis of the Chinese external stocks and flows between 2014 and 2016, and an examination of the currency hierarchy and the international usage of the renminbi (RMB). The authors conclude: the fall in the foreign reserves that occurred in China in 2015–2016 was partially due to (i) a strategy of the Chinese government to diversify its international assets; and (ii) Chinese residents (private entities) increasing their foreign-asset holdings. Besides that, there did indeed occur a capital flight in China in 2015–2016, mostly due to a reduction of the non-resident deposits and loans, but these outflows were partially in RMB. Due to that core difference, the effects on the domestic economy are much lower. Furthermore, the RMB outflows may contribute to the internationalization of the RMB.

Authors: Shai Malome Prince , Kleynhans Carina , Roberson Joseph Robert
Published: November 2021

Corporate Social Responsibility (CSR) initiatives play an important starring role in changing the livelihoods of community members close to casinos around Gauteng. In addition, a contested industry such as gaming needs to ensure CSR initiatives are in place and communicated. The specific objective was to develop a CSR conceptual framework with guidelines for implementation in the casino industry using an Exploratory Factor Analysis (EFA). The study used quantitative research approach which involved eight casinos in Gauteng province, South Africa. Accidental sampling was used with a sample size of 385 with adjacent community members. Structured questionnaires were used as data collection instrument. The results indicated that social aspects and involvement, business and socio-environment, financial contribution, community basic services and food and nutrition are the basic initiatives to be incorporated in casino’s strategies and communicated to different stakeholders in order to improve community satisfaction, ideal public relations and gaining competitive advantage. Findings offer valuable cognizance in helping community members, Gauteng Gambling Board, CSR managers in casinos, employees and other interested stakeholders to review and evaluate the casinos’ CSR policies and implementation strategies.
Relationship between Air Passenger Transport, Tourism and Real Gross Domestic Product in Africa: A Longitudinal mediation analysis
Authors: Chakamera Chengete , Pisa Noleen M
Published: November 2021

This paper analysed the relationships between air passenger transport, tourism and real gross domestic product per capita (rGDPpc) in Africa. Mediation models were analysed using the structural equation modelling approach. This analysis determined the role of a mediator variable in the relationship between dependent and independent variables. Bi-directional positive relationships were found between air passenger transport and rGDPpc, tourism and rGDPpc, followed by air passenger transport and tourism. A certain proportion of air passenger transport’s total effect on rGDPpc was from increased tourism, and some of the rGDPpc’s total effect on air passenger transport were from increased tourism. A sizable effect of tourism on rGDPpc was derived from increased air passenger transport, and a larger portion of rGDPpc’s total effect on tourism was from increased air passenger transport. These percentages show the strength of the mediation (or indirect) paths. The findings imply that it is vital to consider harmonised or integrated policies that facilitate the linkages between air passenger transport, tourism and rGDPpc. Novel in this study, is the scrutiny of the interrelationships between air passenger transport, tourism and rGDPpc in Africa, using longitudinal mediation analysis.
Niche Tourism Research and Policy: International and South African Debates
Authors: Rogerson Christain , Rogerson Jayne
Published: November 2021

The COVID-19 pandemic is a ‘trigger event’ which is remoulding new patterns of demand and supply for the tourism sector. For policy makers and destination managers it highlights the potential significance of niche tourism products. South Africa is viewed as fertile terrain for the promotion of different forms of niche tourism. The aim is to investigate international and South African research debates concerning niche tourism. The paper analyses the conceptual development of niche tourism, international debates, the (re-) emergence of niche tourism on the policy agenda of tourism stakeholders in South Africa and the state of existing literature and debates surrounding niche tourism in the country. The article represents a contribution to the growing and vibrant scholarship around niche tourism and change in the global South.
Virtual Photovoice: Methodological Lessons and Cautions
Authors: Call-Cummings Meagan , Hauber-Özer Melissa
Published: November 2021

Photovoice is a type of participatory inquiry, which is a methodological and onto-epistemological stance that seeks to emancipate marginalized individuals, confront inequity, and work for social transformation. Photovoice incorporates Paulo Freire’s problem-posing education, documentary photography techniques, and feminist thought as an approach for community members to identify shared concerns and construct collective knowledge. It also seeks to challenge unequal power relations by disrupting hegemonic structures in the production of knowledge and policy, as photographs and accompanying descriptions can communicate powerfully about community needs and demands for change. University-based researchers or practitioners facilitate this communication by bringing community perspectives to the attention of government officials and others in positions of power. In this paper, we describe how we adapted this approach for virtual use during the early months of the COVID-19 pandemic. We offer examples of two projects that engaged photovoice in virtual spaces: Courageous Conversations, a youth participatory action research project which Meagan conducts with youth in the United States, and Melissa’s dissertation, conducted with Syrian students who are refugees enrolled in higher education in Turkey. Through these examples we draw out methodological lessons learned as well as challenges of conducting photovoice in virtual spaces. We conclude that whether researchers and practitioners use photovoice as a method in virtual or face-to-face settings, we must remember the emancipatory goals of participatory inquiry, always relying upon and anchoring our methodological decisions in the ontologies and epistemologies of genuine participation that undergird photovoice.

Published: November 2021

The subject of the paper are the possibilities and challenges of teaching drama in a changed social context. In the social context changed by the application of the agenda of globalism in Serbian education, the teaching of drama for preschool teachers begins to lose quality at university. Due to the specific nature of drama as art, online teaching of this subject is not possible. Research of teaching the subject Drama and Movement at the Teacher Education Faculty in Belgrade was shown that teaching was limited to lectures and theoretical exercises during the state of emergency, and that practical exercises were necessary after its abolition. An insurmountable challenge was the protection measures against the corona virus, as a result of which it was impossible to hold exercises of puppet animation and puppet directing, ie to prepare puppet shows (except monodramas). High engagement of professor was necessary for the quality of teaching.

The first concepts of distance learning date back to the 18th century. With the development of information and communication technology, the possibilities of this way of teaching and learning have become more accessible and increasingly popular, especially in the context of non-formal education and at the level of tertiary education. Due to the current epidemiological situation related to the spread of COVID-19, the education system has largely moved online and is at least partly on distance. The changed way of teaching and learning and the use of online tools bring a number of challenges, including legal ones. In this article, we first focus on the legal basis of distance learning during the epidemic and later on one of the area that has been particularly highlighted at this way of teaching, the protection of privacy and personal data. Based on the analysis of normative frameworks and examples from practice, we identify gaps in the regulation of exposed legal aspects of distance learning and during the discussion, we open up possibilities that can lead to new theoretical and practical solutions.

Background. The reconstruction of long bone defects that occur after resection of tumors is a problem that requires constant study. Bone allografts are often used in this scenario. Unfortunately, while they are prepared, allografts partially lose their strength and osteoinductive properties; their survivability in oncological patients is only 40% after 10 years. This is why the search for superior allograft treatment methods and the study of allograft remodeling and incorporation in oncological patients, whose state has been affected by radiation or chemotherapy, is an area of interest. Purpose – study the structure of bone tissue in the distal metaphysis of a rat’s femur after bone allograft implantation (sterilized using gamma radiation or antibiotic saturation) and post-operative intraperitoneal cisplatin injection. Materials and Methods. Experiments were performed on 20 male white rats aged 5–6 months at the beginning of the experiment and weighed 365.8 ± 6.4g. All rats underwent a surgery that created a defect in the distal metaphysis of the femur which was filled with a bone allograft treated with gamma radiation (Control-1 and Experimental-1 groups) or saturated with an antibiotic (Control-2 and Experimental-2 groups). 14 days after allograft implantation, animals from the control groups received an intraperitoneal injection of 2.0–2.4 ml of 0.9% NaCl, while animals from the experimental groups received 2.5mg/kg of cisplatin. Histological analysis and histomorphometry were completed 30 days after the surgery. Results. 30 days after the operation, the smallest relative area of bone tissue (11.79%) was observed in rats from the Experimental-1 group, with gamma radiation treated allografts and post-operative intraperitoneal cisplatin injections. A somewhat higher value was found in the Experimental-2 group (antibiotic saturation + cisplatin) – 31.64%. In the control groups, (intraperitoneal injection 0.9% NaCl), the relative area of bone tissue was 16.7% (Control-1, gamma radiation treatment) and 58.09% (Control-2, antibiotic saturation). The relative area of fibrous tissue was the largest in the Experimental-1 group – 31.55% and the smallest in the Control-2 group – 12.79%. Conclusions. Allograft remodeling occurs along with the formation of bone and fibrous tissue when allografts are used to fill defects in the distal femoral metaphysis of rats, However, the relative percentages of those tissues depend on the allograft sterilization method and the use of cytostatic agents. The largest relative percentage of bone tissue (58.09%) was obtained using an allograft saturated with antibiotics and without the administration of cisplatin. The smallest (11.79%), on the other hand, occurred in gamma radiation treated allografts with cisplatin injected intraperitoneally after the operation

Una de las preocupaciones de los docentes en la educación superior siempre ha sido el grado de formación académica que tienen los jóvenes que acaban la formación secundaria. Tras los acontecimientos sociales del octubre, noviembre de 2019 en Bolivia y la decisión mundial de suspender las clases presenciales y pasar a las clases virtuales, surge la preocupación por si los estudiantes están preparados para migrar de las clases presenciales a las clases virtuales. Por otro lado, los estudiantes también tienen la inquietud de si los docentes están preparados para poder administrar la educación virtual, así como de los padres de familia si existen las condiciones tecnológicas y económicas para poder migrar a la educación superior virtual. Con los resultados del proyecto se quiere develar y clasificar el perfil digital de los docentes y estudiantes en un periodo corto de tiempo. Los usuarios de las TIC’s tanto estudiantes como docentes han cambiado acentuando el uso de las herramientas, pero al mismo tiempo como se han adaptado y adecuado al ritmo y velocidad con que aparecieron nuevas herramientas para la formación sincrónica y asincrónica.

Las actuales circunstancias han permitido el incremento y variedad de estas herramientas que van mucho más aceleradas que la de docentes y estudiantes que pueden incorporar en la actividad académica, sin embargo el reto es justamente medir y cuantificar esta variación para establecer la brecha y clasificación entre los usuarios: docentes y estudiantes en las fases que implica nuestra investigación.

One of the concerns of teachers in higher education has always been the degree of academic training of young people who finish secondary education. After the social events of October, November 2019 in Bolivia and the worldwide decision to suspend face-to-face classes and move on to virtual classes, there is concern about whether students are prepared to migrate from face-to-face classes to virtual classes. On the other hand, students are also concerned about whether teachers are prepared to manage virtual education, as well as parents whether the technological and economic conditions exist to be able to migrate to virtual higher education. The project wants to reveal and classify the digital profile of teachers and students, and how this change in a short period of time. It will be seen how the users of ICTs, both students and teachers, have changed, accentuating the use of the tools, but at the same time it will be seen that the speed with which new tools for synchronous and asynchronous training appeared have a much higher speed than the teachers and students can incorporate them into academic activity.
Substituting dietary fishmeal with soybean meal isolate influences hepatic lipid metabolism and gut microbiota in spotted seabass (Lateolabrax maculatus)

This study was conducted to investigate the effects of partial substitution of dietary fishmeal (FM) by soy protein isolate (SPI) on lipid metabolism and gut microbiota of spotted seabass. A diet containing 30% FM formed the basal diet (FM), and two SPI diets were formulated in which 25% (SPI25) and 50% (SPI50) of FM were replaced by SPI. Each diet was fed to triplicates of fish for 56 days. The results showed that replacing dietary FM with SPI reduced triglyceride and cholesterol contents in the liver and serum, and the hepatic lipid droplets area was also decreased by dietary SPI inclusion. Furthermore, replacement of dietary FM with SPI markedly down-regulated the mRNA expression of genes involved in lipogenesis (srebpc-1c, fas, acc1, hmgcr, pparγ and chrebp) and lipolysis (atgl, hsl, pparα, and cpt1). Moreover, high-throughput sequencing analyses of gut microbiota revealed that dietary SPI inclusion dramatically decreased the Firmicutes/Bacteroidetes ratio. Overall, this study indicated that replacing 25-50% of dietary FM with SPI could reduce lipid accumulation in serum and liver of spotted seabass, which was associated with the suppressed hepatic lipogenesis and the remodeled gut microbiota.
Diagnostic methods and protocols used in investigating Toxoplasma gondii in humans: A review
Authors: Ismael Shmeeran
Published: November 2021

Toxoplasmosis, a zoonotic disease, is a parasitic infection caused by a coccidian protozoan Toxoplasma gondii. In immunocompetent people, the infection is asymptomatic, while it can produce serious signs in immunocompromised people and in developing fetuses. Accurate diagnosis is dependent, mainly, on the clinical features. However, in immunocompromised patients, the diagnosis is very difficult and may lead to misdiagnosis and improper treatment. Today, molecular diagnosis and serotyping are widely used for the diagnosis of T. gondii in many countries. The aim of the present short review is to highlight the current diagnostic methods and protocols that are used for the diagnosis of T. gondii in humans.

Published: November 2021

Epdf and ePUB available Open Access under CC-BY-NC licence. Drawing on place-based field investigations and new empirical analysis, this original book investigates civil society at local level. The concept of civil society is contested and multifaceted, and this text offers assessment and clarification of debates concerning the intertwining of civil society, the state and local community relations. Analysing two Welsh villages, the authors examine the importance of identity, connection with place and the impact of social and spatial boundaries on the everyday production of civil society. Bringing into focus questions of biography and temporality, the book provides an innovative account of continuities and changes within local civil society during social and economic transformation.
ЗА УПОТРЕБАТА НА НЕОЛОГИЗМА КАНСЕЛИРАМ В БЪЛГАРСКИЯ ЕЗИК /
ON THE USE OF NEOLOGISM KANSELIRAM IN THE BULGARIAN LANGUAGE
Authors: TILEV ENCHO
Published: November 2021

The current paper discusses the use of the neologism kanseliram in the Bulgarian language. Examples from social networks show that this verb is increasingly found in the speech of modern Bulgarians, although there is no objective need for it. The reason can be explained by the intense influx of anglicisms – a phenomenon observed in many of the modern languages that have been influenced in one way or another by Western culture.
