PALIMPSESTS AND SYMBOLS

The purpose of this essay is to resolve an apparent contradiction in the critical reception of the epic poem Invenção de Orfeu, by the preeminent Brazilian poet Jorge de Lima (1893 – 1953). The poet, according to his own account, had two principal aims in writing the poem: firstly, to effect a radical regeneration of poetry and poetics in order to renew religious and specifically Catholic values, in modern society, and secondly to modernise the classical and Renaissance epic genre, in its original Aristotelian sense, within the contexts of the twentieth century and the modern era. However, the critical scholarship concerning Invenção de Orfeu expresses the opposite view, that the work comprises a compendium of apparently unconnected and disassociated ideas, genres, textual fragments and poetic figures of all kinds, with no discernible sequence, and no thematic core. My aim, therefore, is to demonstrate the status of Invenção de Orfeu as a unified entity, with reference to Jorge de Lima’s single motive, repeatedly stated for composing his epic: to expound the principal tenets of the Catholic faith and “restorepoetry in Christ”. I will use theory drawn from recent scholarship on theology and literature to illustrate the compositional structures underpinning the poem: firstly the one “root-metaphor” of the holy Trinity and Jesus Christ as the divine Logos, a concept on which all the verse in Invenção de Orfeu is based; secondly, the reintegration of “chains of memory” in order to re-establish a lineage of religious belief in a secularised world. Both of these principles, however, are realised through a poetics whose “invention” comprises a dynamic and multi-dimensional process of re-creation and re-composition of language by the poet. To illustrate, I will examine two particular features of Invenção de Orfeu, which, as I argue, transform Invenção de Orfeu into a thematic and stylistic unity. Firstly, the intertextuality inherent to the work: the appropriation and adaptation of classical and Renaissance epic texts interwoven in dense and intricate ways with Jorgede Lima’s own creation, to create a palimpsestic text. Secondly, the process of symbolisation, that is, the creation of symbols by the poet to generate a network of links, connections and relations within the language of the poem, which serve to render the text as one cohesive and integrated whole.Keywords: Brazil, religion, epic, poetry

One session of fMRI-Neurofeedback training on motor imagery modulates whole-brain effective connectivity and dynamical complexity

In the past decade, several studies have shown that Neurofeedback (NFB) by functional magnetic resonance imaging can alter the functional coupling of targeted and non-targeted areas. However, the causal mechanisms underlying these changes remain uncertain. Here, we applied a whole-brain dynamical model to estimate Effective Connectivity (EC) profiles of resting-state data acquired before and immediately after a single-session NFB training for 17 participants who underwent motor imagery NFB training and 16 healthy controls who received sham feedback. Within-group and between-group classification analyses revealed that only for the NFB group it was possible to accurately discriminate between the 2 resting-state sessions. NFB training-related signatures were reflected in a support network of direct connections between areas involved in reward processing and implicit learning, together with regions belonging to the somatomotor, control, attention, and default mode networks, identified through a recursive-feature elimination procedure. By applying a data-driven approach to explore NFB-induced changes in spatiotemporal dynamics, we demonstrated that these regions also showed decreased switching between different brain states (i.e. metastability) only following real NFB training. Overall, our findings contribute to the understanding of NFB impact on the whole brain’s structure and function by shedding light on the direct connections between brain areas affected by NFB training.

Quality of transport services and customer satisfaction measurement

The development and functioning of the global economy market is not possible without a net-work of transport connections - communication infrastructure, as well as a service provider - consumer relationship. Transport is a technological process of the distance of people, objects or energy. Knowledge of the logistics system and its processes is essential for fully functioning and effective logistic activities in the field of goods turnover. The functioning of enterprises operating on modern world markets without effective logistics is almost impossible, hence the constant search for tools to improve its processes, which provide added value for the customer, while maintaining the cost-quality ratio of the services provided. Building an appropriate relationship with the customer, taking care of customer service standards and professional customer service is a long-term and developmental process, which is nothing else than a mutual benefit transaction. Customer satisfaction should be constantly tested in terms of satisfaction and loyalty as well as the perception of the standards introduced and services offered. The customer satisfaction survey is used to illustrate the perception of the conditions that guide the customer. This article describes the methods of measuring customer satisfaction in the point of view quality of transport services.

POLITICAL CAMPAIGN STRATEGY OF YOUNG PKS POLITICIANS IN SEEKING CONSTITUENT SUPPORT

After the reforms that were launched in 1998, now politics in Indonesia is increasingly dynamic. Indonesian politics is now not only dominated by senior politicians, but also young politicians have emerged. These young politicians are also very aggressive in campaigning to win people's votes. What they highlight is that young politicians are relatively clean and have not been exposed to past political sins. This study aims to analyze the Political Campaign Strategy of Young Politicians of Prosperous Justice Party (PKS) in Seizing Constituent Support in 2019 political contestant. The method used in this research was descriptive qualitative method. The results show that the political campaign strategy of young politicians of Prosperous Justice Party (PKS) in seizing constituent support included seven stages. First, analyzing the political map, which was analyzing the social conditions of the region that would be used as a campaign site. Second, determining the target of votes. Third, forming a campaign team by forming a successful team to help the campaign process. Fourth, formulating a campaign strategy. Fifth, analysis of social connections (networks). Sixth, organizing campaigns by setting campaign schedules. Seventh, escorting the vote result by selecting and determining witnesses and volunteers in the electoral process in escorting the election process and vote result.

A Paper World

This essay examines early modern alba amicorum as collections of social and intellectual networks, personal memories, and other textual and visual materials. In what way are these ‘paper worlds’ related to collections of objects, and to networks of connections? How do they interact with other book and manuscript genres, such as the emblem and the costume book? Taking the album of the Dutch collector Bernardus Paludanus (1550-1633) as a case study, an argument will be made regarding the conceptual and material kinship of alba with other forms of manuscript and print collections. The intermediality and materiality of friendship books will be shown to be crucial aspects for understanding how this medium functioned within early modern cultures of collecting and the communal production of memory and knowledge.

Networking as a new type of partnership in education and science

The transition from an industrial to a post-industrial society is determined, first of all, by building an open society, which puts the ideas of rationalism, freedom of innovation, and the promotion of ideas at the forefront. An open society gives rise to open structures, including in higher education. Universities, as platforms for collective creativity, learning, innovation, are opening to meet social needs, work to transform the economy in particular and society as a whole. These are no longer just universities with an established network of connections and strong international relations; they are already hubs that implement networking, which allows different participants to create new educational and scientific products through cooperation, exchange of resources and experience. This article analyzes the world experience in building educational hubs, highlights the main elements of their architecture. Based on the experience of the D.Serikbayev East Kazakhstan Technical University, the assumption proved that the transformation of a university into a hub is a natural step for organizations that have public recognition, strong science, and innovative educational projects. The methodology for creating a network format for the life of the university is described in detail, the process of developing common universal approaches to the implementation of the network interaction of the university in the educational and scientific fields is characterized, and the concept and model of the hub chosen by the university is substantiated. The format of network interaction of EKTU allows successfully implementing projects in the educational, research, and production areas.

Gyral peaks: Novel gyral landmarks in developing macaque brains.

Cerebral cortex development undergoes a variety of processes, which provide valuable information for the study of the developmental mechanism of cortical folding as well as its relationship to brain structural architectures and brain functions. Despite the variability in the anatomy–function relationship on the higher‐order cortex, recent studies have succeeded in identifying typical cortical landmarks, such as sulcal pits, that bestow specific functional and cognitive patterns and remain invariant across subjects and ages with their invariance being related to a gene‐mediated proto‐map. Inspired by the success of these studies, we aim in this study at defining and identifying novel cortical landmarks, termed gyral peaks, which are the local highest foci on gyri. By analyzing data from 156 MRI scans of 32 macaque monkeys with the age spanned from 0 to 36 months, we identified 39 and 37 gyral peaks on the left and right hemispheres, respectively. Our investigation suggests that these gyral peaks are spatially consistent across individuals and relatively stable within the age range of this dataset. Moreover, compared with other gyri, gyral peaks have a thicker cortex, higher mean curvature, more pronounced hub‐like features in structural connective networks, and are closer to the borders of structural connectivity‐based cortical parcellations. The spatial distribution of gyral peaks was shown to correlate with that of other cortical landmarks, including sulcal pits. These results provide insights into the spatial arrangement and temporal development of gyral peaks as well as their relation to brain structure and function.

Methodology for Measuring the Benefits of Participation in Business Clusters

Running a business in the complex and global world requires cooperation of entities with different complementary resources and competences. A socio-economic organization which wishes to be competitive in the modern market must possess proper human, financial, material and information resources and be able to use them in the most effective way. A significant element in creating a network of connections is the absorption of knowledge and its skillful use linked with shaping innovation. Stimulation of the flow of knowledge between cooperating entities increases the level of innovation of undertaken projects. Enterprises and institutions that join together in cluster initiatives bring their material potentials, skills and experience in order to survive in a competitive market (most often small and medium-sized enterprises, scientific and research institutions) and to multiply the possibilities of achieving benefits. The accepted thesis of the article which claims that new, cooperating, innovative inter-organizational networks supported by local institutions contribute to an increase of their competitiveness in the market does not require special justification. However, the research problem is to indicate the methods by which it is possible to assess if participation in a business cluster brings benefits in specific areas of activity.The starting point for considerations in the presented study is the assumption that participation in clusters provides economic, social and scientific entities with economic or marketing benefits as well as knowledge development and socio-economic revival of a region. The main scientific inquiry, not only for the purposes of this thesis but also knowledge necessary for managers, is the effectiveness level of the adopted project. The aim of the article is to present research methods that can be used to assess the benefits that individual organizational entities achieve due to participation in a business cluster or a cluster initiative.

Temporal Intertwining in a Slovenian Narrative

This article, based on the assumption that narrativity and temporality are closely related, explores the Chronotope of the Slovenian historical tale Martin Krpan z Vrha (1858) by Fran Levstik. It focuses on the narrative time as presented by the epic story, as well as on the time frame in which this narrative was published. According to the assertion that literary time and place are intrinsicallysss connected, the time-line of this epic text is viewed as a constituent part of the setting and therefore the geographical location is also highlighted. The analysis of the story-line reveals that the tale, presenting three time frames clearly separated by centuries, when viewed from a historical perspective, displays cohesion and credibility despite the intermingling of two temporal settings. It is significant that the story was published in the aftermath of the Spring of nations (1848) in which Slovenians demonstrated the increasing awareness of their ethnic identity. Since scrutiny of the author’s biography reveals that this text was heavily influenced by the time-related issues, my premise is that the narrative time, viewed in the network of connections, can best be elucidated by the concepts of Chronos and Kairos. They can foreground the relationship between the narrative period of this tale, the date of its publication and even highlight the specificity of the time when the protagonist of this tale became the best known Slovenian national hero.

Reduction of Power Consumption and CO2 Emissions as a Result of Putting into Service High-Speed Trains: Polish Case

This article presents the results of analyses of energy efficiency and environmental outcomes of putting into operation high-speed trains—first of that kind in Poland—in 2014 on upgraded 3 kV DC lines. Comparative analyses of these trains in Poland have not been carried out so far and provide a new approach to assessing the feasibility of their adoption and, in a broader context, the advisability of replacing conventional with high-speed rail transport. The analysis supports the advantages of high-speed railway (HSR) and the need to develop a network of high-speed connections using energy-efficient trains in Poland. Putting these trains into service reduced CO2 emissions, which is significant in Poland as a country relying heavily on power generated in coal power plants and complies with the assumptions of the sustainable development policies and EU Green Deal. The outcomes of our analysis can be used for transportation planning to mitigate climate change and the presented approach provides a method of quantification of environmental impacts of HS trains.

End-to-end performance assessment of a 3D network for 6G connectivity on Mars surface

Space Agencies from all over the world are planning human missions on the Red planet in the next 20–30 years. The landing of astronauts and their sojourn on the Martian surface will impose the presence in situ of some basic supporting infrastructures. Recent research by NASA highlighted the urgent necessity of providing efficient and readily-available wireless connection on the Martian surface, as well as long-haul connection to Earth. Thus, to fulfill the former, the objective of this paper is to study and assess a flexible 6G-based 3D network solution for mobile connectivity on Mars. 6G is going to provide guaranteed Quality-of-Service (QoS) for heterogeneous applications, while optimizing the use of the network resources. The Radio Access Network (RAN) of such an infrastructure will be fully softwarized together with the Next Generation Core (NGC). 6G 3D networks will employ drones, small satellites and orbiters due to the reduced distances between them, which can support low-latency wireless links. Moreover, rovers, landers and humans are regarded as end users of the system. An in-depth analysis regarding trade-offs to be accounted, when selecting a specific orbital altitude is detailed. Intensive end-to-end (E2E) emulation trials in OpenAirInterface (OAI) environment is carried out to test the feasibility of the whole network. The performance is evaluated by means of metrics such as E2E delay, packet loss and throughput. Finally, computational complexity and memory usage is estimated for each node of the proposed architecture.

Modelling the laminar connectome of the human brain.

The human connectome is the complete structural description of the network of connections and elements that form the 'wiring diagram' of the brain. Due to the current scarcity of information regarding laminar end points of white matter tracts inside cortical grey matter, tractography remains focused on cortical partitioning into regions, while ignoring radial partitioning into laminar components. To overcome this biased representation of the cortex as a single homogenous unit, we use a recent data-derived model of cortical laminar connectivity, which has been further explored and corroborated in the macaque brain by comparison to published studies. The model integrates multimodal MRI imaging datasets of both white matter connectivity and grey matter laminar composition into a laminar-level connectome. In this study, we model the laminar connectome of healthy human brains (N = 30) and explore them via a set of complex network measures. Our analysis demonstrates a subdivision of network hubs that appear in the standard connectome into each individual component of the laminar connectome, giving a fresh look into the role of laminar components in cortical connectivity and offering new prospects in the fields of both structural and functional connectivity.

Multidisciplinary Approach in Diagnosing Patients with Mental Health and Intellectual Disability

It is possible to properly diagnose and treat a person with intellectual disability and mental health problems, but it requires a lot of work on the part of a doctor, nurse, professional medical care, proper rehabilitation and cooperation with a speech therapist, psychiatrist and many others. To improve the functional capacity of this person, it requires the help of a wide variety of professionals to meet their needs. One of the examples of interdisciplinary cooperation in this area is the “Circles of Support” program implemented by the Polish Association for People with Intellectual Disability in Poland. Support circles assume the creation of a group of supporters around a person with a disability, in accordance with their needs, combining formal (family doctor, psychiatrist, psychologist, personal assistant, social worker, therapist, lawyer) and informal support (family, friends, acquaintances, neighbors) , salesperson in your local store). The support is strictly focused on the needs of a person with a disability, and according to their individual preferences, it is fully inclusive. This goal can be achieved by preparing a person with a disability and the environment in a way that enables them to function safely in their local community based on the concept of supportive circles. The only way to build a system of care for of people with intellectual disabilities and their relatives is to rely on networks of connections - people and institutions, on their real commitment and on working out mechanisms supporting the empowerment of people with disabilities - in life, physical, financial matters.DisclosureNo significant relationships.

An Intelligent Perception Model and Parameters Adjust Method for Quality of Experience

With the coming of the 5G network era, Quality of Experience (QoE), which is used to describe experience quality of customers in the Direct Connect (DC) network, is critical to operators and hence has been widely studied. The existing evaluation method for QoE is unable to dynamically adjust QoE parameters so there will be deviations to reflect the real experience of customers when complaint events occur. In this paper, a novel progressive QoE evaluation model for network products is formulated. Subsequently, considering the customer complaints occurrences which represent that the real customer experience and previously calculated QoE may mismatch, the rules based on application types to judge whether QoE parameters needs to be adjusted are made. Then, a dynamic adjustment model of QoE parameters is further developed to reflect complaint customer experience. Finally, the obtained experimental result verified that the proposed dynamic perception method for QoE can accurately characterize the real customer experience. The evaluation result for QoE model based on customer satisfaction questionnaires proves the effectiveness of the QoE-aware model. The evaluation result for adjusted QoE model based on business complaints shows that the adjusted QoE calculation variance reduction rate exceeds more than 50%, which indicates that the proposed method has better ability to reflect the real customer experience.

How do consulting firms share knowledge with clients in the Arab world? A cultural embeddedness perspective

ABSTRACT This paper explores the challenges that consulting firms and client firms are facing in knowledge sharing in the context of the Arab management consulting industry, and how local culture works in solving these challenges. Taking knowledge sharing and the cultural embeddedness perspective as the theoretical lens, the study adopts a comparative case study design to explore how mechanisms of cultural contextualisation affect knowledge-sharing behaviours. The findings highlight the benefits of cultural embeddedness in knowledge sharing between consulting firms and client firms through identifying the importance of Wasta (a social network of interpersonal connections) in skill-set formation, follow-on consultancy, niche specialist cultivation, and the establishment of network consulting. Our study provides industry players with a holistic framework to leverage Wasta to achieve knowledge sharing, which sheds light on a neglected cultural aspect in the management consulting industry.

Energy Efficient UAV Flight Control Method in an Environment with Obstacles and Gusts of Wind

This article presents an energy-efficient method of controlling unmanned aircraft (fixed-wing UAVs), which consists of three groups of algorithms: aerial vehicle route planning, in-flight control, and algorithms to correct the preplanned flight trajectory. All algorithms shall take into account the existence of obstacles that the UAV must avoid and wind gusts in the UAV’s area of operation. Tests were carried out on the basis of the UAV mathematical model, stabilization and navigation algorithms, and Dryden turbulence model, considering the parameters of the UAV’s propulsion system. The work includes a detailed description of constructing a network of connection that is used to plan a UAV mission. It presents the algorithm for determining the actual distances between the different points in the field of action, which takes into account the existence of obstacles. The algorithm shall be based on methods for determining the flight trajectory on a hexagonal grid. It presents the developed proprietary UAV path planning algorithm based on a model from a group of algorithms of mixed integer linear problem (MILP) optimization. It presents the manner in which the pre-prepared flight path was used by UAV controllers that supervised the flight along the preset path. It details the architecture of contemporary unmanned aerial vehicles, which have embedded capability to realize autonomous missions, which require the integration of UAV systems into the route planning algorithms set out in the article. Particular attention has been paid to the planning and implementation methods of UAV missions under conditions where wind gusts are present, which support the determination of UAV flight routes to minimize the vehicle’s energy consumption. The models developed were tested within a computer architecture based on ARM processors using the hardware-in-the-loop (HIL) technique, which is commonly used to control unmanned vehicles. The presented solution makes use of two computers: FCC (flight control computer) based on a real-time operating system (RTOS) and MC (mission computer) based on Linux and integrated with the Robot Operating System (ROS). A new contribution of this work is the integration of planning and monitoring methods for the implementation of missions aimed at minimizing energy consumption of the vehicle, taking into account wind conditions.

“The Case of Comrade Dragiša Pavlović”

The article deals with the question of the homogeneity of the Yugoslav media landscape, which is already considered to be distinctly republican in modern literature and newspapers. From a variety of topics in the politically heated 1980s, the authors chose reports on events at the Eighth Plenum of the Central Committee of the League of Communists of Serbia as the basis for analysis. The rare Yugoslav political weeklies reported on this issue most extensively and in detail, and article deals with presenting and analyzing their discourse. The analysis suggests that the political weeklies focused on the republican environment but, because of the extensive network of connections between the media outlets and journalists in question, were significantly more Yugoslav-oriented than they were thought at the time of publication.

Aberrations in the Cross-Talks Among Redox, Nuclear Factor-κB, and Wnt/β-Catenin Pathway Signaling Underpin Myalgic Encephalomyelitis and Chronic Fatigue Syndrome.

There is evidence that chronic fatigue spectrum disorders (CFAS-Ds), including myalgic encephalomyelitis (ME), chronic fatigue syndrome (CFS), and chronic fatigue with physiosomatic symptoms including when due to comorbid medical disease, are characterized by neuroimmune and neuro-oxidative biomarkers. This study was performed to delineate the protein–protein interaction (PPI) network of CFAS-D and to discover the pathways, molecular patterns, and domains enriched in their PPI network. We performed network, enrichment, and annotation analyses using differentially expressed proteins and metabolics, which were established in patients with CFAS-D. The PPI network analysis revealed that the backbone of the highly connective CFAS-D network comprises NFKB1, CTNNB1, ALB, peroxides, NOS2, tumor necrosis factor (TNF), and interleukin-6 (IL-6) and that the network comprises interconnected immune-oxidative-nitrosative and Wnt/β-catenin subnetworks. Multiomics enrichment analysis shows that the CFAS-D network is highly significantly associated with cellular (antioxidant) detoxification, hydrogen peroxide metabolic process, peroxidase and oxidoreductase activity, interleukin-10 (IL-10) anti-inflammatory signaling and neurodegenerative canonical Wnt, the β-catenin complex, cadherin domains, cell–cell junctions and TLR2/4 pathways, and the transcription factors nuclear factor kappa B (NF-κB) and RELA. The top 10 DOID annotations of the CFAS-D network include four intestinal, three immune system disorders, cancer, and infectious disease. The custom Gene Ontology (GO) term annotation analysis revealed that the CFAS-D network is associated with a response to a toxic substance, lipopolysaccharides, bacterium, or virus. In conclusion, CFAS-D may be triggered by a variety of stimuli and their effects are mediated by aberrations in the cross-talks between redox, NF-κB, and Wnt/β-catenin signaling pathways leading to dysfunctions in multicellular organismal homeostatic processes.
