Authors: Ustun Karatop Eslin , Eren Cimenci Cagla , Melisa Aksu Ayla
Published: October 2022

Cytotoxicity experiments are carried out to evaluate whether a chemical has cytotoxic potential. Because of its ease of use and compatibility with data collected from in vivo investigations, cell-based cytotoxicity studies have emerged as a viable alternative to animal trials in research. Cell-damaging events such as apoptosis, autophagy, and necrosis may occur after exposure to cytotoxic substances. Thanks to the cell-based cytotoxicity studies, basic information is obtained about the cytotoxic effects of the tested substance. To measure cell viability, a variety of techniques are used. Regardless of the sort of cytotoxicity investigation that was carried out, the crucial thing is to figure out how much metabolic activity there is in the cells at the end of the experiment. Cytotoxicity detection methods are generally colorimetric, luminescent, and enzymatic methods. In colorimetric methods, measurement is based on color change using tetrazolium salts, such as MTT, MTS, XTT, WST. Three main steps are followed in tetrazolium compound toxicity tests. Toxic compounds are introduced to cells in the initial stage. The poisonous chemical is eliminated in the second phase and followed by the addition of the tetrazolium compound. The metabolically active cells are determined in the last stage by using a spectrophotometric approach to measure color change.

Mycotoxins are secondary metabolites present in foods which can cause adverse effects on humans and animals. Therefore, developing a simple, effective, sensitive and validated analytical method to monitor mycotoxins is essential. Sample preparation is an important step in the analysis of mycotoxins and other contaminants from complex food matrices. Food industries in developed and developing countries have faced serious challenges with contamination of mycotoxins especially aflatoxin in food and feed products. Thus, corn and cereal-based foods are mostly affected right from pre and postharvest periods. Owing to the complexity and structural nature of mycotoxins in foods and feeds there is an urgent need for simple, effective and environmentally friendly methods of sample preparation for the detection and quantification of aflatoxins in food samples. The paper reviews the application of the Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) method for the analysis of aflatoxins in foods.
A Federated Learning-Based Civil Aviation Passenger Value Analysis Method and MaaS Construction Considerations in the Epidemic Background
Authors: Chen Sien
Published: October 2022

Airline customer demand has plummeted since the COVID-19 pandemic, with about two-thirds of the world’s fleet grounded. Under such circumstances, the airline needs to adjust its market strategy. Mining the value of passengers and providing differentiated services for passengers with different values are key to the differentiated competition of airlines. In the case of ensuring data privacy, this study introduces a privacy-preserving federated learning method, which combines airline internal data with external operator data, comprehensively considers multiple dimensional characteristics of passengers. This study compares a unilateral model using airline data with a joint model combining airline internal data and operators through federated learning. The result shows that the joint model based on federated learning is more accurate than the unilateral model. Based on this result, this study puts forward the thinking about passenger mining and insight in the construction of MaaS under the epidemic situation, constructs a customer journey map according to the characteristics of the segmented population, and proposes the idea of providing different transportation services for the segmented population. This research provides important theoretical and practical implications for the airline digital transformation and MaaS construction under the epidemic.

A hybrid network, which consists of the sections of communication lines with the transmission of signals of different physical nature on different transmission media, has been considered. Communication lines respond differently to threats, which allows to choose the line with the best performance for the transmission of information. The causal diagram of events that determine the state of the information transmission network, such as changes in emergency/accident-free time intervals, has been presented. The application scheme of the protection measures against dangerous events has been shown. To verify the measures, a matrix of their compliance with typical natural disasters has been developed and relevant examples have been given. It is suggested to evaluate the flexibility of the telecommunication network by its connectivity, characterized by the numbers of vertex and edge connectivity, the probability of connectivity. The presented scheme of the device for multi-channel information transmission in a hybrid network allows the choice for the transmission of information to the channel with the best performance. Using this device is the essence of the suggestion about increasing the flexibility of the network.

Published: October 2022

Authenticating the content of the digital image has profound influence in legal matters and in court rooms. Image forensics plays an important role towards it. Proposed approach helps to authenticate the original image by generating a content based image signature that is a unique fingerprint for the image. Our novel approach establishes spatio triad relationship among features and finds the centre of gravity or centroid of the same after indexing. Topology of the triad relationship for the content based low level feature descriptors is preserved through aggregation until single key feature is deduced which is a 128 bit signature hash value and represented in decimal form. Density of feature keypoints influences the centre of gravity which acts as a unique signature for the given image. Manipulated image cannot contribute to restore / regenerate the same signature. We have verified our authentication approach for standard benchmark image dataset like MICC-F220, Columbia Image Splicing Evaluation dataset and Image manipulation dataset from Friedrich Alexander University and have found satisfactory results for the same. Content based image signature obtained is used to verify authenticity of image and for retrieval of video from database. Content based image fingerprint generated can also be considered for embedding as a watermark.
A Secure LEACH Protocol for Efficient CH Selection and Secure Data Communication in WSNs
Authors:   Department of Electronics and Communication Engineering, Jawaharlal Nehru Technological University, Hyderabad, Telangana, India, Sanapala Ravi Kumar , Duggirala Srineevasa Rao
Published: October 2022

Due to the applications of wireless sensor networks (WSNs) in distinct fields, like civilian and military, environmental monitoring, and target tracking, etc., it became the important research area for researchers. Therefore, an efficient organization of network topology is needed for multi-hop data aggregation based on the energy constrained WSNs with large scale deployment for making the routing task simpler, balancing the load efficiently, and enhancing the network lifetime. The low-energy adaptive clustering hierarchy (LEACH) is an architecture of application-specific protocol, which is used for WSNs. However, this LEACH protocol suffered from more energy consumption in network without considering the cluster heads (CHs) distribution on a rotation basis. In addition, the complex security mechanisms are not sufficient due to limited bandwidth and other restrictions that the sensor nodes have. Thus, it is essential to improve the energy efficiency, CH stability and secure data transmission in WSN’s, which is the main objective of this work. Motivated from these three challenges, this article proposes a stable and secure LEACH (SS-LEACH), in which a new and improved protocol of LEACH is proposed for enhancing the stability of CH and energy efficiency as it considers the nodes’ consumed energy ratio (CER) for CH selection and random number generation, here after the proposed LEACH is named as CER-LEACH. In addition, it aims to prevent the previously elected CH node and it will get another chance in the current round. This method correlates the threshold used in traditional LEACH with the energy consumption ratio of each node. Further, it also introduces a hybrid reputation-based data transmission (HRDT) scheme for secure data transmission. With the proposed CER-LEACH protocol, WSNs achieves better performance in terms of secured communication, network lifetime, and energy consumption based on the analysis of simulation results as compared to state-of-art approaches.

The consumption of wine these days is becoming more common in social gatherings and to monitor the health of individuals it's very important to maintain the quality of the wine. For the assessment of wine quality many methods have been proposed. We have described a technique to pre-process the “Vinho Verde” wine dataset. The dataset consists of red and white wine samples. The wine dataset size has been reduced from a total of 13 attributes to 9 attributes without any loss of performance. This has been validated through various classification techniques like Random Forest Classifier, Decision tree Classifiers, K-Nearest Neighbor Classifier and Artificial Neural Network Classifier. These classifiers have been compared based on two performance metrics of accuracy and RMSE values. Among the three classifiers Random Forest tends to outperform the other two classifiers in various measures for predicting the quality of the wine.
Artificial Neural Networks for Earth-Space Link Applications: A Prediction Approach and Intercomparison of Rain-influenced Attenuation Models

The impact of rain-influenced attenuation (RIA) has a more pronounced effect as frequency increases, especially in the tropical zones with heavier rainfall than the temperate zones. The International Telecommunication Union (ITU) has recommended a universal model which may not fit well in this tropical region due to the temperate data used to develop the model. It is therefore necessary to adopt locally measured data to develop a suitable model for each region, as also recommended by ITU recommendation 618-13. The experimental site for this study is at the Department of Physics, Federal University of Technology, Akure, Nigeria (7.299° N, 5.147° E) in the tropical rainforest region of Nigeria. In the present work, the backpropagation neural network (BPNN) of the artificial neural network (ANN) is trained based on time-series rain rates data collected between 2015 and 2019 to predict time-series RIA. Based on four inputs (rain rate, rain heights, elevation angle, and polarization angle), the generated data was subjected to training, validation, and testing. The ANN was further trained using the Levenberg-Marquardt algorithm to fit the inputs and the targets to create a dynamic model for RIA forecasting. Further validation was tested using actual data of rain attenuation from a Ku-band beacon at the site. Subsequently, the RIA model created by the ANN was compared to those generated using the synthetic storm technique, ITU, and the actual rain attenuation obtained from a beacon measurement. The highest rain rate observed was about 225.8 mm/hr with a corresponding rain attenuation of about 61 dB as estimated by the SST model and about 68 dB by the ITU model, while the predicted attenuation by the ANN is 55 dB. This implies that an extra power of 6 dB and 13 dB is added by the SST model and ITU model, respectively, for the downlink signal, to compensate for the rain attenuation link. The results also reveal that during 0.01 percent of an average year that signal may be attenuated, a relatively tiny margin of error between anticipated rain attenuation using ANN and the SST model is exceeded. In general, the new ANN-generated RIA model had the lowest root mean square error, average relative error, and standard deviation at the selected time percentages, according to the model validation. Hence, the new ANN model can predict more effective RIA in the region when compared with the global ITU-R model.
Data Protection has Entered the Chat: Analysis of GDPR Fines
Authors: Mike Nimród
Published: October 2022

Before the adoption of the EU-GDPR, researchers remarkably argued on law enforcement of personal data protection being „toothless” and a “paper tiger”. Almost three years after its enforcement date, the GDPR fines are increasing, and the world is beginning to witness the effect of sizeable fines awarded to organizations. This analysis aims to discover potential correlations between GDPR fines, and equally the lack of them. Such correlations might help to tap into trends that are followed by Data Protection Authorities (DPA) in their fining practices. This paper specifically describes the fines issued by the Romanian DPA, while also containing qualitative research findings extracted from discussions with interview subjects. The aim of this paper is to evaluate the possibility to construct a prediction model that is based on linear regression analysis and provide for future direction on the field of legal data analysis.
Augustine’s Treatment of the Great Psalm
Authors: O’Donovan Oliver ,   Philosophy Documentation Center
Published: October 2022

An ancient Hebrew poem of uncertain background and fastidiously subtle formal technique is made the subject of a commentary by a fifth-century Latin bishop with no Hebrew, working with a poor Latin translation, who, moreover, dismisses the formal complexities of the composition as irrelevant to interpretation. Claiming to detect hidden depths beneath the Great Psalm’s limpid surface, Augustine uses it as an opportunity to revisit some of the favorite themes of his own later writing. Has he read the text with sufficient sympathy to discover anything in it that might correspond to the poet’s intentions? Comparing his approach with Ambrose’s earlier and very different one, we notice some unexpected interpretative strengths in the earlier work. But Augustine’s attentiveness to connections between lines and stanzas and to the repetition of key vocabulary reveals a close attunement to the emotional movements of the poem. His contention that the Psalmist’s “law” is to be understood as Saint Paul’s “law of faith” is not imposed on the text, but allowed to emerge from its sequential development, and especially from its opening and closing lines.
Catholic Social Thought and the Capability Approach
Authors: DeCesare Tony ,   Villanova University
Published: October 2022

Despite a growing body of literature that engages both Catholic social thought and the Capability Approach, little has been done to explore what these two traditions of thought might offer to a reassessment of the project of global democracy promotion. This essay brings Catholic social thought and the Capability Approach into conversation for this purpose. What emerges is a framework for thinking about and engaging in what the author calls democratic democracy promotion (DDP). DDP is based on a broadened conception of democracy and avoids a dogmatic commitment to the promotion of Western liberal democracy; it takes a needs-based approach to the allocation of externally driven democracy assistance; and it prioritizes education initiatives as central components of democracy promotion. Refashioned as such, democracy promotion has the potential to bring about more participatory democratic processes, a more inclusive global democracy, and a critical and caring mass of global democrats.
A Critical Race Theology Analysis of Catholic Social Teaching as Justification for Reparations to African Americans for Jim Crow
Authors: Mitchell Nicholas Ensley ,   Villanova University
Published: October 2022

This article is a critical race theology analysis that asserts that Catholic social teaching established in documents such as the Catechism of the Catholic Church, Populorum progressio, Caritas in veritate, and the Pontifical Council for Justice and Peace’s Contribution to the World Conference against Racism, Racial Discrimination, Xenophobia and Related Intolerance justifies reparations for the state of oppression commonly called Jim Crow, or segregation society, from the US government because it denied African Americans “truly human conditions.”
The Magisterium and Social Doctrine
Authors: Bersnak P. Bracy ,   Villanova University
Published: October 2022

Debates about Catholic social doctrine often revolve around whether a given theory or practice is compatible with the magisterium or not. There is a body of scholarly literature on the nature and scope of the magisterium, but little has been written on the magisterium as it pertains to social doctrine. This essay explores what magisterial documents and scholarship say about the sources, levels, and scope of the magisterium in relation to social doctrine. It then considers how the levels of magisterium can help the faithful understand contemporary teaching on capital punishment. The better they understand the magisterium in relation to social doctrine, the more charitable and fruitful debate will be.

The taxonomic status of the nominal taxon Dryophis prasinus flavescens Wall, 1910 is reevaluated herein. Based on molecular data generated from fresh collections of Ahaetulla prasina (H. Boie in F. Boie, 1827) auctorum from Northeast India and, additionally, morphological data from museum specimens originating from the same areas, we resurrect this taxon as Ahaetulla flavescens (Wall, 1910) comb. nov. We clarify the status, identity and locations of its type specimens, rediscover, redescribe and illustrate those specimens and also designate a lectotype in order to effect a proper taxonomic redefinition of this nominal taxon. We provide further details on the morphology and diagnosis of this species and elucidate its phylogenetic position. We also provide a summary of the natural history and distribution of this species. Adding to the known cryptic diversity and genetic divergence within Southeast Asian populations, this work also hints at the need for a taxonomic revision of the A. prasina complex. This work complements a previous study on the A. prasina complex focusing on populations in Indonesia. Taken together, these two studies represent phylogenetic reconstructions from different populations of the A. prasina complex across its distribution range, on the Asian mainland and the surrounding islands.
Prevalence and risk factors of acne among adolescents in Kosovska Mitrovica: A cross-sectional study
Authors: Milić Stefan , Janković Janko
Published: October 2022

Background/Aim: Acne can occur in people of all ages, but mostly affects the population at puberty. Given the high prevalence and large impact that acne has on young people, the aim of this study was to assess adolescents' knowledge about factors that improve or worsen the clinical picture of acne, as well as to evaluate the sources used to obtain information on acne. Methods: This cross-sectional study was conducted on a sample of 460 high school pupils from the Medical School and Gymnasium in Kosovska Mitrovica. A self-administrated questionnaire was used. Univariate and multivariate logistic regressions were used to model the association between gender (males/females) or presence of acne (no/yes) and potential exacerbating and ameliorating factors, as well as sources of information. Results: 36.7 % of the respondents were male and 63.3 % were female. 48.9 % of high school pupils confirmed that they had acne. The main factors that worsen the condition of acne, were irregular face washing (88.7 %), hormones (87.0 %), fatty foods (80.9 %) and sweets (79.3 %). The majority of respondents believed that the intake of more water (83.9 %), cosmetic treatment (77.8 %), dietary changes (75.9 %), holiday (54.1 %) and sunbathing (39.3 %) affect improving acne. Taking more water (OR = 1.77; 95 % CI = 1.01-3.11) as a factor in improving acne was significantly more common in girls, while boys more often believed that sunbathing (OR = 0.62; 95 % CI = 0.41-0.94) and weight loss (OR = 0.53; 95 % CI = 0.32-0.88) affect the improvement of acne. The most important sources of information about acne were the Internet (73.0 %) followed by parents (62.6 %), friends (54.1 %), and a doctor (42.8 %). Conclusion: Acne was more common in women and those with a positive family history. The presence of misconceptions among young people regarding the factors that improve or worsen the condition of acne indicates the need for additional education.
Food intolerance
Authors: Jandrić-Kočić Marijana
Published: October 2022

Food intolerance is a non-immunological response induced by a food or food component in a dose that is normally tolerated. It includes pseudo allergic and pharmacological effects caused by: salicylates, biogenic amines, sulphites, sodium glutamate, colours and preservatives, sweeteners, or enzymopathies. The pathophysiology, clinical manifestations, diagnosis and treatment of the most common food intolerances have been presented in this review article. The literature search was done with the help of the following keywords: intolerance, food, additives, carbohydrates and gluten within PubMed, Embase, Scopus, SCIndeks and Hrčak databases. According to the literature, it may be argued that the lack of standardized tests accounts for the discrepancy between the perceived prevalence of food-related adverse effects, which are extremely common, and the actual prevalence of non-immunological reactions to food within these events. Food intolerance is manifested primarily by gastrointestinal and then extraintestinal (neurological, cardiovascular, respiratory and dermatological) signs and symptoms. Diagnosis requires a detailed medical history, physical examination, as well as keeping a diet and symptom diary, implementing an elimination diet and double-blind placebo-controlled oral food exposure tests. Treatment includes dietary modification, supplementation and treatment of the underlying condition in persons with secondary intolerance.

Along with the growing demands on the tourism and hospitality market, soft skills have been increasingly stated as the main prerequisites for employability. Therefore, this study set out to investigate the health tourism students' perceptions of the soft skills they possess with an emphasis on the contribution of English language courses to their development. The data were collected employing the tailor-made questionnaire which addressed 12 soft skills deemed the most necessary for the inclusion in the (health) tourism labour market. Students perceived their soft skills to be at an average to a moderately high level of development. Likewise, an average to a moderately high level of the contribution of English language instruction was noted. These findings indicate that there is much room for improvement and can be informative for various stakeholders in the education process. On the one hand, the study has revealed that the language courses have a favourable impact on soft skills development, and on the other, it has produced a relatively good representation of the enhancements to be made in this regard.
Polysemy-related problems in ESP students: A case study
Authors: Mićović Dragoslava , Beko Lidija
Published: October 2022

Detected as a problem in foreign language learning, polysemy has been a subject of many various studies and from many various aspects. The problem of polysemy is particularly important in English for Specific Purposes, or in our case English for Police Purposes, since it very often gets unnoticed by learners. Having learnt one meaning in a General English course, learners are usually unaware that the same word can have a new meaning in technical texts. The aim of the case study is to examine to what extent the students can recognize the senses of polysemous words in different contexts and if the level the particular meaning is associated with (according to the CEFR) influences the percentage of correct/incorrect answers. We used a questionnaire and a self-designed vocabulary test to collect the data both about the participants and their practical knowledge of polysemy. The study was conducted with a group of I-year students of Forensic Engineering at the University of Criminal Investigation and Police Studies. The results obtained should help improve the course of English for Police Purposes.
Functional abilities of children as factors of school achievement
Authors: Đoković Sanja , Kovačević Tamara , Ostojić-Zeljković Sanja
Published: October 2022

Understanding the factors which affect students' school achievement is an important knowledge source for strategic planning and encouraging changes in education. In this paper, we focused on examining the factors related to personal characteristics. The aim of this research was to determine the relation between school failure and achievements in certain functional abilities, such as: academic skills (reading, writing), attention, communication (receptive and expressive speech), class participation, and behavior. The sample included 195 younger school-age children of both genders. Students' functional abilities were assessed by the S.I.F.T.E.R. scale (Screening Instrument for Targeting Educational Risk). The results showed that school achievement correlated with all assessed functional abilities. The coefficient of multiple determination showed that 48% of individual differences in children's school achievement can be explained by individual differences in the given model of functional abilities. It should also be emphasized that only two functional abilities, attention and communication, were singled out as statistically significant particular predictors.
Opportunities and challenges in mastering polysemous words and idioms in foreign language learning based on analogous procedures in the native language
Authors: Stakić Mirjana , Arsić Zvezdan
Published: October 2022

The paper points out some of the potential problems in foreign language learning that may arise during the enrichment of one's vocabulary with polysemous words and idioms (phrasemes). The aim is to analyse when exactly their acquisition should start in second language learning, as well as to indicate some of the methodological possibilities that allow for its realisation. Their acquisition requires consistency and continuity in the presentation of these lexical layers, and understanding-interpretation of contextual meaning. It is necessary to start enriching student vocabulary with such lexical layers in a timely manner. This timeliness means that the acquisition of such vocabulary and lexical layers should begin at an early age, in the very first stages of second language learning, and some methodological procedures, such as didactically guided play, allow for its realisation. Different types of games (imagination and drama games: pantomime, role-play, and dramatization), which can also be used to for modelling games in foreign language learning, and enriching student vocabulary with polysemous words and idioms, as well as creating an authentic context that allows students to understand the concept of figurative meaning in real-life language use, are presented on the examples of the Serbian language as the native language.

Figurações nômades em manipulações digitais: experimentações de um Estágio de Docência em Artes Visuais
Authors: Barrionuevo Gustavo , Maio Eliane Rose , Stubs Roberta Parpinelli
Published: October 2022

Preocupadas com a formação da subjetividade, este artigo procura refletir sobre as práticas nômades nas experimentações feitas em um Estágio de Docência na disciplina de Arte Digital do curso de Artes Visuais da Universidade Estadual de Maringá (UEM). A partir de uma selfie, as estudantes foram instigadas a manipular as fotografias em softwares de edição (como o Photoshop) inspiradas pelos processos artísticos da drag. Essa proposta parte de uma abordagem rizomática com o currículo, permitindo que ele seja atravessado por questões agenciadas pelo seu fora. Assim, trazemos para esta discussão os conceitos de figurações nômades, uma espécie de mapa político que nos permite entender os processos de subjetivação contemporâneos, e de rostidade, uma máquina de controle que, pela formação de um rosto, insere-nos em territórios fechados de experiência. A manipulação de imagens digitais, para além dos processos coercitivos de controle dos corpos, é usada em nossa proposta como uma prática de si com capacidade de agenciar movimentações nômades para a formação de uma subjetividade mais libertária.

Published: October 2022

O texto apresenta os resultados parciais de uma pesquisa, ainda em realização, junto ao curso de Licenciatura em Artes Visuais da Universidade do Estado de Santa Catarina, Brasil. Durante o levantamento dos dados, optou-se por observar e descrever as palavras encontradas em trabalhos de conclusão de curso (TCCs) do ano de 2018, os quais pertencem a estudantes do referido curso, em dois aspectos: palavras-chave e títulos. Na pesquisa, a palavra funciona em um sistema de linguagem que não é apenas representação, no sentido de espelho ou como expressão concreta da formação docente dos estudantes, mas sim como interstício aberto em que a docência pode vir a se insurgir. Com esta proposição, surgem cartografias em que a palavra, como algo nômade, móvel e errante, propõe-se a indicar as pistas dos trabalhos desenvolvidos em arte e educação pelos graduandos.

O personagem conceitual Nômade, protagonista e causa ativa dos dramas de HF, é apontado como "figura emblemática do Homem como criador". Em permanente movimento, vai ao encontro do Módulo de Destruição, imóvel na Posição Alfa antes de iniciar mais um Ciclo de Destruição. Cabe ao Nômade confrontar-se com, penetrar e atravessar o Módulo, de modo a transferir-se de uma Cidade Mais-que-Perfeita prestes a ser destruída para outra cidade, prestes a experimentar um novo Ciclo de Vida. O Módulo de Destruição é representado graficamente por um imenso cubo. O Nômade é representado por uma pequena esfera (o Nômade e o Módulo de Destruição se relacionam por vias de suas diferenças). Se o Nômade mantiver essa trajetória e essa estratégia de confronto e atravessamento, ele (it) conquistará o que Platão descreve como "uma forma móvel de eternidade".
Recombinações artísticas e tecnológicas como possibilidade de resistência política
Authors: Bitelo Henrique de Souza , Caimi Claudia Luiza
Published: October 2022

Desde as vanguardas modernistas pode-se perceber a dissidência dos modos comuns de se fazer arte e da utilização da tecnologia. Aos poucos as criações vão abandonando a distinção tradicional entre produção e consumo, original e cópia; não se tratando mais de compor formas desde um material bruto, mas sim de utilizar objetos que já possuem uma forma configurada e que estão em circulação no mercado cultural para a criação artística. As artes se transformam em uma ilha de edição que subverte e faz interagir diversas formas sociais, linguagens de criação, afetos e efeitos. Através da reutilização e recontextualização podem ser compostas produções artísticas múltiplas, utilizando das formas preexistentes como caixa de ferramentas e que confrontam as estratégias de gerenciamento da vida, trazendo possibilidades de resistência política mediante às recombinações artísticas e tecnológicas.

Para tratar do encontro e das relações entre elementos (tangíveis e intangíveis), uso a imagem de rede (em diferentes abordagens tecnológicas) e adoto os pensamentos de Ingold (2015) sobre peregrinação e modos de conhecer. Através de cinco relatos de experiências pessoais, simulo cenários de crise, exponho a processualidade e busco comunicar o contexto (a visão) em que surge e se desenvolve esta pesquisa. Por fim, este artigo reflete sobre o nomadismo em territórios, em campos do conhecimento e na interação humana com o digital.
Determining the genetic and agronomic variations in lines from Samsun tobacco growing areas
Authors: KURT Dursun , KINAY Ahmet , SAYGILI İbrahim , KANDEMİR Nejdet
Published: October 2022

Tobaccos grown in Samsun are known all over the world. Samsun tobaccos are grown using nonregistered populations traditionally maintained by local farmers. The present study was conducted to determine the genetic and agronomic variations in Samsun tobaccos. Fifty-eight lines were collected from Samsun in tobacco growing area. These lines were analyzed using eighteen SSR markers. Polymorphic information content (PIC) values of markers ranged between 0.0 and 0.702. Forty-two alleles were obtained from 18 SSR markers. Average number of alleles per SSR locus was 2.33. Forty-eight lines were different for at least one SSR locus, indicating a high level of variation. The forty-eight lines were evaluated in two field trials along with local varieties Nail and Canik for agronomic characteristics such as plant height, number of leaves, leaf width, leaf length, leaf yield, grade index, leaf sugar and nicotine contents. High level of variation was also evident for agronomic characters. Lines No: 2, 11, 13, 21, 28 and 41 were notable for their superior agronomic characteristics. Some of these lines could be directly registered as new cultivars, but they should be further evaluated in future field trials in multiple environments. These lines could also be used as parents for the development of new cultivars.

Pour les Mafa du Cameroun septentrional, le fait
d’être mordu par un chien constitue une indication que la
personne ainsi atteinte est sorcière. C’est à travers l’examen
des circonstances qui ont entouré la mort d’un homme
mordu par un chien que nous tenterons de retracer les liens

Shame and Secrecy of Do Not Resuscitate Orders: An Historical Review and Suggestions for the Future
Authors: O’Connor John A.
Published: October 2022

This paper clarifies some of the longstanding difficulties in negotiating Do Not Resuscitate Orders by reframing the source of the dilemmas as not residing with either the patient or the physician but with their relationship. The recommendations are low cost and low-tech ways of making major improvements to the care and quality of life of the most ill patients in hospital. With impending physician-assisted death legislation there is an urgency to find more efficient and beneficial ways for clinicians and patients to address resuscitation issues at the bedside. Paradigmatic shifts in the nature of the patient-physician relationship will need to be encouraged by the larger community. These encouraged shifts address the concepts of passive/inferior patient – active/superior physician, patient ownership of and access to all their health care information, and treating the patient as a major participant in the delivery of health care. These recommended changes will not in themselves make any patient, physician or other healthcare provider more humane and open in the patient’s final days. The goal, instead, is to have changes to the context of the discussion provide an encouraging environment for more open communication and a balanced relationship among participants with the patient being the most important.
Modernisation de la Loi sur les langues officielles : priorités
Authors: Bastarache Michel
Published: October 2022

Pour réussir à moderniser la Loi sur les langues officielles, il faut d’abord définir l’objet d’une telle entreprise. Cela exige que l’on ait une conception claire de l’objet de la Loi. Ensuite, il faut se demander si les défaillances du régime actuel se trouvent au sein de la Loi elle-même ou en ce qui a trait à sa mise en oeuvre sur le plan réglementaire et administratif. Or, à l’heure actuelle, les principales carences relèvent de la mise en oeuvre et non du cadre législatif comme tel. Des défis importants existent par rapport à l’accès aux services et à la langue de travail, mais ils peuvent être affrontés sans modifier de façon substantielle la Loi. Il y a néanmoins certains points sur lesquels la Loi devrait être modifiée, notamment en ce qui concerne l’obligation de l’offre active, la partie VII et des principes d’interprétation.
L’effectivité de la Loi sur les langues officielles, proposition d’une grille d’analyse
Authors: Forgues Éric
Published: October 2022

Plusieurs observateurs et intervenants soulignent que l’application et le respect des lois linguistiques au pays, notamment la Loi sur les langues officielles (LLO) du Canada, continuent de poser un problème. Dans le contexte où plusieurs consultations ont eu lieu pour réviser cette loi, plusieurs intervenants ont rappelé cette problématique et proposé de renforcer l’application de la LLO. La note de recherche qui suit présente une grille d’analyse qui tente de saisir les contextes juridique, social et organisationnel qui influencent l’effectivité d’une loi linguistique. Suivant une approche multidisciplinaire, nous avons élaboré cette grille dans le cadre d’un projet de recherche sur l’effectivité des lois linguistiques provinciales dans le secteur de la santé. Nous jugeons utile de la présenter, car elle peut servir dans d’autres secteurs et pour une meilleure application de la LLO. Plusieurs autres travaux de recherche permettront de tester, de préciser et de valider cette grille d’analyse.
Dynamics, Costs, and Survival of Minorities: Optimal Language Policies for Increasing the Vitality of Minority Languages
Authors: Wickström Bengt‐Arne
Published: October 2022

It is assumed that language policy can influence the language in which parents choose to raise their children. A basic model of language transmission in the family is outlined and the effect of different policies on the vitality of a minority language is analyzed. It is argued that the habitation patterns and numerical strength of the minority have a strong influence on the cost effectiveness of various policy measures. It is shown that by classifying language policies into four distinct categories we can assign different policies to different minorities in a cost-effective manner, based on the size of the jurisdiction where the minority lives and its numerical strength within it. We provide a general intuitive discussion and a specific example to support the general analysis.
Jean-Marc Piotte, définisseur de situation en quatre saisons
Authors: Couture Jean-Pierre
Published: October 2022

Le but de cet article est d’analyser l’ensemble du parcours de Jean-Marc Piotte dans les revues d’idées. Membre fondateur de la revue Parti pris en 1963, il participe aux premières années de cette revue qui catalyse un printemps de la vie intellectuelle du Québec. Puis, à l’heure des avant-gardes des années 1970, il cofonde la revue Chroniques. Alors que la canicule marxiste est rapidement supplantée par un automne politique aussi douloureux que polémique, Piotte révise ses positions et collabore ponctuellement aux Cahiers du socialisme, à Conjoncture politique au Québec, à Possibles et à Relations. Dans les années 2000, il replonge dans le projet d’une revue d’idées en publiant régulièrement des textes dans le collectif À bâbord!, et ce, jusqu’en 2016. Définisseur de situation, Piotte a analysé des tendances jugées délétères, allant du felquisme au marxisme-léninisme, puis du désengagement syndical au nationalisme conservateur. En tant que penseur rompu aux écrits de Gramsci sur le rôle de la culture, Piotte a aussi été un promoteur de l’éducation, de la pensée autonome et de l’insubordination démocratique à partir d’une conception du rôle critique que doivent jouer les intellectuels.
Demography and Polygyny in a Southern Sudanese
Agro-pastoralist Society
Authors: Roth Eric Abella , Kurup K. B.
Published: October 2022

Survey data from eight Toposa villages were used to
examine the demographic effects of polygyny upon this
Southern Sudanese agro-pastoralist population. Direct age standardization
of fertility rates revealed lower fertility for
women in polygynous unions, as measured by maternal
age and marital duration. Indirect techniques of mortality
estimation indicated higher childhood mortality for offspring
of polygynous marriages. The underlying rationale
for these demographic differentials is attributed to Toposa
social structure, including the economic value of women,
gerontocracy and residential patterns.
Les villages palissadés de la vallée laurentienne, un patrimoine archéologique unique
Authors: Santerre Simon
Published: October 2022

Les palissades suscitent la curiosité. Elles symbolisent le défi que les premiers colons durent surmonter, soit celui de créer une enclave de protection au coeur d’un milieu hostile, et ce, avec des moyens plutôt rudimentaires. Des forts, des postes de traite et des missions ont notamment été ceints d’une clôture de pieux. Plusieurs villages ont aussi été dotés de tels ouvrages défensifs, mais dans plusieurs cas, il s’agissait plutôt de petits fortins et de redoutes aménagés en marge des habitations et ne protégeant que quelques bâtiments importants, dont l’église, le moulin et le manoir. Toutefois, trois villages français établis à la fin duxviie siècle, soit La Prairie, Boucherville et Pointe-aux-Trembles se distinguent d’autres établissements ruraux. En effet, ces villages étaient entièrement ceints de clôtures de pieux dans lesquelles les maisons étaient regroupées et organisées autour d’une trame de rues. Ces trois villages ont laissé des témoins archéologiques uniques au Québec, ainsi qu’une empreinte toujours visible dans le paysage.
