Comparative Study of Mechanical Properties of Concrete Using Marble Dust as Partial Cement Replacement and Addition of Polypropylene Fiber
Authors: Ajaz Mubashir , Chalotra Shakshi
Published: July 2022

Ordinary Portland cement (OPC) is used as the primary binder to produce concrete. The amount of the CO₂ released during the manufacture of OPC is in the order of one ton for every ton of OPC produced. Attempts made to reduce the use of OPC in concrete are receiving much attention due to environment related issues. In the present study marble dust is used as a partial replacement for cement. It has been estimated that several million tons of Marble Dust are produced worldwide from extracting to finishing process. Hence its utilization has become an important alternative material because of its cement like properties. Marble dust is also easily available at very less cost. Concrete is characterized by quasi-brittle failure i.e; once failure is initiated; nearly complete loss of loading capacity takes place. By addition of randomly distributed fibers in the concrete matrix concrete can be modified to perform in a more ductile manner which prevent and control initiation, propagation and coalescence of cracks. The fibers prevent surface cracking through bridging action leading to an increased resistance of the concrete. This paper presents results of an experimental program to determine mechanical properties of concrete as cement is replaced with marble dust with known percentages (0%, 5%, 10%, 15%) [5] [6] for the grade of M30 and addition of polypropylene fibers of different percentage (0%, 0.5%, 1%, and 1.5%). The concrete test samples were submitted to compressive strength tests after 7 and 28 days of moist curing, as well as flexure and splitting tensile strength tests. Overall Strength of Concrete (Compressive, Tensile & Flexure) showed a reasonable increase upto a limit of 10% for Marble Dust and 0.5% for PP Fibers [1].

Authors: Hugar Praveen , Pershad Mayur , Sathvika T. , Bhukya Ganesh
Published: July 2022

Malware is any programme that gains access to or instals itself on a computer without the permission of the system's administrators. For cyber-criminals to achieve their nefarious objectives and purposes, a variety of viruses has been widely deployed. To tackle the growing number of malicious programmes and lessen their hazard, a novel deep learning framework is developed that employs NLP approaches as a starting point and combines CNN and LSTM neurones to record locally spatial correlations and learn from sequential longterm dependencies. As a result, for the malware classification job, high-level abstractions and representations are automatically derived. The accuracy of categorization rises from 0.81 (best by Random Forest) to about 1.0.
Fuzzy Logic Based Load Frequency Control of Hybrid Power System Integrated with SMES
Authors: ahmad Sameen ul haq , Saini Satish , Safiullah Sheikh , Farooq Zahid
Published: July 2022

The use of a Fuzzy logic-based controller for automatic generation control (AGC) and load frequency control (LFC) of two area power plants in an interconnected power system is proposed in this paper. In addition, a superconducting magnetic Energy Storage (SMES) unit is being considered in two areas. After a sudden load disturbance, the implementation of SMES combination arrests the initial fall in frequency deviation and tie-line power deviation. The simulation results show that the proposed SMES unit improves system performance significantly. The system's sensitivity analysis is carried out by altering the parameters and operating load conditions from their nominal values. Even when the system is subjected to wide variations in loading conditions and system parameters, the optimised gains of the proposed fuzzy logic- based controller and fuzzy controller along with SMES controllers do not need to be reset. Finally, different types of load patterns are used to test the effectiveness of the proposed controller design. The simulation results show that the Fuzzy PID controller combined with SMES outperforms the Fuzzy PID controller alone. The simulations were run using the MATLAB software.
System Dynamics and Frequency Regulation of a Multi-Area Power System Using an Optimal Controller
Authors: Rashid Anab , Saini Satish , Safiullah Sheikh , Farooq Zahid
Published: July 2022

For system frequency control, the current work proposes a multi-area power system integrating various renewable sources. An effective controller with intrinsic superior capabilities of restricting peak deviation, steady state errors, and oscillatory behavior of a dynamic system is an apparent alternative for autonomous generation control of interconnected power systems. The most difficult part of using a controller is figuring out how to get the most out of it. Because of its space complexity, the trial and error method of determining the benefit by indirect optimization with an acceptable performance index appears to be insufficient. As a result, it appears that using an effective algorithm technique to find the maximum gains for the controllers is the best option. The gains of the controllers are addressed in this work and thus are optimized using a meta-heuristic technique in this study.

Authors: Angelow Krassimir , Kolkovska Natalia
Published: July 2022

The aim of this paper is to evaluate stationary propagating wave solutions to the two dimensional Boussinesq equation. To solve the resulting nonlinear fourth order elliptic problem we use a combination of high order finite difference schemes, an iterative procedure and new asymptotic boundary conditions. A number of numerical results are obtained for the validation of the method and for the dependence of the wave's shape on the velocity c and dispersion parameters. We also give a comparison with the numerical results and best-fit formulae given in [4, 5].
Distribution of The Boolean Functions of n Variables According to Their Algebraic Degrees
Authors: Bakoev Valentin
Published: July 2022

Knowledge about the enumeration and distribution of Boolean functions according to their algebraic degrees is important for the theory as well as for its applications. As of now, this knowledge is not complete: for example, it is well-known that half of all Boolean functions have a maximal algebraic degree. In the present paper, a formula for the number of all Boolean functions of n variables and algebraic degree = k is derived. A direct consequence from it is the assertion (formulated already by Claude Carlet) that when n to infty, almost a half of all Boolean functions of n variables have an algebraic degree = n-1. The results obtained by this formula were used in creating the sequence A319511 in the OEIS. The discrete probability a random Boolean function to have a certain algebraic degree is defined and the corresponding distribution is computed, for 3

Published: July 2022

Fuzzy matching is a widely used technique in computer-assisted translation and some other fields (it is implemented in most database engines and is used in autocompleting of data, for example). In this paper, fuzzy matching in the aspects of approximate string matching is investigated. Basic algorithms like Soundex, Bitap, Boyer-Moore [1, 2] are covered. Using the results about those algorithms, several database engines are compared and a new way of handling fuzzy matching is offered.
Numerical Integration of Two-Dimensional Complex-Valued Functions for the needs of BIEM
Authors: Laskov Lasko M.
Published: July 2022

Numerical integration is a key problem with numerous applications, including the boundary integral equation method (BIEM). GSL [7] provides powerful implementations of a broad variety of well-known numerical methods and algorithms. However, its routines have certain limitations: the numerical integration based on QUADPACK library [2] is implemented only in the case of one-dimensional functions. In this paper we present an extension of the GSL numerical integration routines for the special case of two-dimensional complex-valued functions. The presented approach is part of our effort to build a BIEM software system for solving a 3D elastodynamics problem for wave propagation in a continuously inhomogeneous half-space.

Subsektor peternakan merupakan salah satu kontributor gas rumah kaca (GRK) nasional. Kontribusi GRK dari subsektor ini masih di bawah 2% dari total emisi GRK secara nasional. Kontribusi ini diasumsikan akan terus meningkat sejalan dengan upaya penambahan populasi ternak sebagai efek dari diterapkannya salah satu program pemerintah untuk pemenuhan protein hewani asal ternak. Penghitungan emisi GRK dari peternakan mengikuti panduan yang dikeluarkan oleh Intergovernmental Panel on Climate Changes (IPCC). Metode Tier 1 telah digunakan untuk menghitung emisi GRK dari peternakan yang dilaporkan oleh Kementerian Lingkungan Hidup dalam National Communication dan 1st Biennial update progress yang didaftarkan ke United Nations Development Programme (UNDP). Pada metode Tier 1, nilai faktor emisi yang digunakan adalah faktor acuan IPCC yang umum untuk wilayah Asia. Akurasi penghitungan perlu dilakukan dengan menggunakan informasi dan data lokal sehingga dapat menggambarkan emisi GRK yang sesuai dengan kondisi peternakan di Indonesia. Buku ini berisi tentang proses dan hasil penghitungan emisi GRK dengan menggunakan metode yang lebih akurat, yaitu Tier 2 pada semua jenis ternak di Indonesia. Kami berharap buku ini bermanfaat bagi pihak-pihak yang bergerak di bidang perubahan iklim.
Equivalised household income inequality in Łódzkie Voivodship
Authors: Jędrzejczak Alina , Pekasiewicz Dorota
Published: July 2022

The analysis of income distribution in the regional perspective is an important issue in the context of the cohesion policy implemented in the EU countries, one of the postulates of which is smoothing differences in the standard of living and liquidation of poverty The aim of the study presented in the paper is to determine changes in the distribution of equivalent household incomes, and in particular the changes in the degree of inequality and the level of poverty and richness in Łódzkie Voivodship. This voivodship is an interesting object for research, as in the period of the political transformation it underwent many changes which influenced the economic situation of households. The main variable of interest was household equivalent income which was determined using three power equivalence scales. To estimate the inequalities, the study applied measures sensitive to income disparities in different parts of the distribution, namely the Gini coefficient in the central part of the distribution, the index of disparity in the extreme parts of the distribution, and the Zenga index, sensitive to inequalities at each point of the distribution. The levels of poverty and richness, i.e. phenomena related to income inequality, were analysed in the same way. Income distribution in Łódzkie Voivodship was next compared with the same indicator for the whole Poland. All the calculations were based on data for the years 2016–2020 drawn from the Household Budget Survey conducted annually by Statistics Poland.
The obtained results indicate increasing income inequality in the period under consideration, with the visible discrepancy between the extremal decile groups. In 2020, the inequlities became wider; moreover, the share of households experiencing poverty increased, while the share of relatively affluent households decreased. Overally, the poverty level was higher, and the richness level was lower in the studied period in Łódzkie Voivodship than in the whole country. The analysis of the sensitivity of the indices of inequality, poverty and richness to the change in the equivalence scale demonstrates that the choice of the scale flexibility parameter affects the level of the analysed measures, but does not significantly affect the assessment of the changes in these parameters over time.
Sustainability of agriculture in view of the agricultural censuses of 2010 and 2020
Authors: Zegar Józef S.
Published: July 2022

Data provided by official statistics, including those obtained through agricultural censuses, can serve to analyse and assess the progress made in the sustainable development of agriculture, which is consistent with the objectives set out in policy documents and development strategies. In 2021, Statistics Poland published the first results of the 2020 Agricultural Census (2020 AC), comparable with the 2010 AC data, along with the tendencies of the development of agriculture in Poland observed in certain areas. The aim of the paper is to make a preliminary and selective assessment of the changes occurring in sustainable agriculture on the basis of the available agricultural census data. Furthermore, the study is meant to emphasise the need for Statistics Poland to collect and publish additional data allowing for a fuller illustration of the progress made in the area of agricultural sustainable development. The data provided by Statistics Poland enable a general assessment of the changes taking place in the agrarian structure, labour input, agricultural land use, agricultural technologies, industrial resources input, and specialisations and sources of maintenance of households with a user of an individual agricultural holding in the context of agricultural sustainability. However, a more comprehensive and complete evaluation requires Statistics Poland to take into account information from sources other than agricultural censuses in its further, post-census publications. Moreover, the aforementioned evaluation necessitates the establishment of new farm groupings according to sustainability indicators, the type of gmina (municipality), the used agricultural technologies and practices, labour input, farms’ market orientation and sources of support, the areas of different agricultural valorisation (LFA), the Natura 2000 areas, and others.

Authors: Mattarozzi Victorio
Published: July 2022

Saúde e equidade social estão relacionadas à proteção do meio ambiente, como aponta a legislação ambiental brasileira. Neste artigo, objetivou-se demonstrar quão importante é para os bancos adotar robusta gestão de riscos socioambientais, evitando, assim, a corresponsabilização jurídica por danos socioambientais causados por atividades que financiam. Para tanto, realizou-se reconstituição histórica do financiamento concedido à Tractebel Energia pelo BID para construção de uma usina hidrelétrica e suas consequências socioambientais na comunidade local. Evidencia-se a responsabilidade solidária dos bancos por dano socioambiental, quando conhecem o destino final dos recursos emprestados e têm ingerência na gestão socioambiental do financiado. Quanto às questões socioambientais nos processos de decisão de negócios, verifica-se a vulnerabilidade dos bancos aos seus impactos, mas salienta-se a oportunidade de eles se tornarem agentes da sustentabilidade, canalizando os recursos para preservação do meio ambiente e promoção do desenvolvimento sustentável.

The purpose of this study was to find out the factors that are responsible for entrepreneurs to quit entrepreneurship and join the job industry. This qualitative study was designed to fulfill the objectives via interviewing ex-entrepreneurs and getting first-hand information from business owners themselves who had faced the problem in their business tenure. Interviewing the respondents brought out a number of factors that had ultimately forced them to wind up their businesses. These factors were then carved out broadly categorized as internal or external factors which led to either managerial or financial reasons. Conducting this research was a tedious task as people are not willing to share their previous or unpleasant memories furthermore. They were hesitant to share a part of their personal life experience. Due to limited resources and time the research was conducted in the city of Lahore which and therefore limited in its scope. Nevertheless, this study has produced credible information which can be useful for future entrepreneurs.

Leading trends over the last couple of years tend to be the increasing value of big data and analyzing the information through analytics. The information has tremendous value; fast moving consumer goods (FMCG) businesses must capitalize on the assortment of information by proper and in-depth evaluation with the usage of big data analytics (BDA). Objective: This article seeks to spotlight the changing dynamics of the SC managing atmosphere, to recognize the way the two leading trends will influence supply chain management (SCM) in future, to demonstrate the advantages which may be derived, and to generate suggestions to provide SC managers if BDA is adopted. Method: A survey was done amongst workers of multinational FMCG businesses across the world: the Americas, Asia etc. Systemic situation modeling is used in the quantitative evaluation to analyze the information gathered from surveys. The process of deriving value from the large quantities of information within the SCM is defined. Results: The adoption of BDA technologies can develop extensive value-added as well as a financial gain for companies and can quickly be a regular during the entire market. It is demonstrated, through examples, the way SCM location might be influenced by these brand-new developments and trends. Within the examples, BDA have been adopted, utilized, and applied effectively. Big data and analytics to draw out value coming from the information can create a big influence. Conclusion: It is clearly suggested chain administrators pay attention to these 2 trends, since better usage of BDA can ensure they hold abreast with innovations modifications, which could help improve company competitiveness.

XIII Premio de Estudios Iberoamericanos La Rábida 2020. Esta investigación es una aproximación interpretativa a las formas estéticas de las imágenes producidas por el pintor Gregorio Vásquez y por la poetisa Josefa del Castillo, inscritas en el arte colonial neogranadino. Específicamente, del pintor Gregorio Vásquez se considera el Símbolo de la Trinidad y El Juicio Final; mientras que de la poetisa Josefa del Castillo, aborda sus escritos Mi Vida y Afectos Espirituales. Aunque atiende las imágenes conceptuales que componen su retórica visual a través de las metáforas, para el caso de Josefa del Castillo, y de los temas iconográficos, para el caso de Gregorio Vásquez; por ejemplo, se centra en la apropiación y el sentido de las formas estéticas que emplearon para la producción de sus obras artísticas, sin obviar referencias a tipos iconográficos o literarios empleados, cuando sea necesario. Ya que no contamos con estudios específicos que consideren su estudio de manera conjunta sobre este tema, vale la pena abordarlo hermenéuticamente, atendiendo a sus contrastes y de manera comparativa, con el fin de establecer un punto de partida de cara a nuevas investigaciones.

Authors: Martínez-Moreno F.J.
Published: July 2022

IV Premio de Estudios Onubenses "La Rábida". En esta obra se describen de forma detallada las investigaciones científicas de ámbito geológico y geofísico realizadas en el Cerro del Castillo, donde se emplaza la Gruta de las Maravillas. Estas investigaciones han derivado en el descubrimiento de nuevas cavidades pertenecientes al sistema cárstico de la cueva. La Gruta de las Maravillas, desarrollada a través de mármoles que componen parcialmente el cerro, se extiende desde el lateral occidental hasta la parte central de dicha colina. Numerosos estudios realizados a lo largo de años sugerían la alta probabilidad de la continuidad de la Gruta de las Maravillas al otro lado del caos de bloques que colmata la sala del Gran Lago y constituye el final de la gruta localizada en la parte central del cerro. Debido a que la exploración de nuevas cavidades desde el interior se tornó imposible, esta se llevó a cabo desde la superficie del cerro mediante métodos geológicos y geofísicos no invasivos. Este estudio pone al descubierto la existencia de nuevas cavidades similares a la conocida Gruta de las Maravillas que se extienden desde la parte central hasta el lado oriental del Cerro del Castillo. Finalmente, se ha realizado una perforación mecánica que ha detectado una de las nuevas cavidades, cuyas imágenes e incluyen en este libro.

Tax collection system in the mining sector: Legal framework for an efficient and transparent system
Authors: Sumaili Adolphe Kilomba , Massawe Hanifa
Published: July 2022

DRC and Tanzania are two neighboring countries with mineral rich deposits that could be the driving force of their economies. Yet, they remain among under developed countries in the world in general and in Africa in particular. Their populations are still languishing under the poverty threshold while their youths are desperate. After increasing a fiscal burden of corporates exploiting its mineral in 2018, the DRC intended to make the mining sector more fruitful than ever before. 3 years following such ambitious reforms, outcomes are yet to be seen. In fact, the mining sector has not increased the public revenue todate. Lack of transparency in the management of the sector should be fingered. Meanwhile, the Congolese government seems willfully negligent to vehemently address this abnormal situation. On the other hand, Tanzania has reportedly performed well in the mining sector thanks to the strong leadership of its late President Dr Joseph John Pombe Magufuli. Despite such efforts some questions still evolve with regard to the importance of the sector towards socio-economic development. In the same line specific question has been asked on how does one enhance contribution of the mining sector to significant increase of GDP for the two countries? To respond to the question, this paper outlines the state of play of legal reforms underwent by the two countries in the mining sector in the last ten years. Thereafter it suggests ways of increasing transparency in the sector and shows what DRC should learn from Tanzania.
Improving Land Access by the Youth for Agriculture: Whither legal Incentives?
Authors: Wamuyu Hannah
Published: July 2022

The paper analyses challenges that contribute to poor youth participation in agriculture. Access to land by the youth is identified as one of the challenges that contribute to minimal participation. Land is identified as a scarce resource which access by all the old and the young is a challenge. The author posits that improving access of land by the youth can enhance youth involvement in agriculture therefore which can make a positive contribution to food security and economic development of the country. This can go hand in hand with promotion of off farm activities which can be run by the youth who make up the population of the country. The paper discusses laws and policies on access to land and youth participation in agriculture as part of development activities. The author notes that the legal framework provides for interventions which if implemented can strengthen youth participation in agriculture. Comparatively, Kenya can adopt practices from other countries which have helped improve access of land for the youth. Such practices include creation of zones for planned agriculture development that can be set apart for the youth; inter sales of community land can be encouraged to favor the youth; inver vivos transfer of land can be encouraged from the old to young generations; and land can be leased from the community to be given to the youth for development.
Furcht ist nicht in der Liebe
Authors: Henrich Dieter
Published: July 2022

Henrich's reflection takes its cue from a sentence of John, which emphasizes a characteristic of the partnership of man and woman in the spirit of Christianity: namely, that at its core it is the absence of fear for itself. John's theology of love is connected to this understanding of life. In his analysis of self-consciousness as an indubitable grounding, however, Henrich shows how a purely human understanding of love can be gained. Admittedly, real life bonds are most often formed and experienced in fluctuation between many modes of understanding. The procedural mode of this reasoning itself then becomes the theme of the investigation.

Catastrofe e meraviglia. Storia, filosofia e etica animale in una novella di Anna Maria Ortese
Authors: Marsulli Claudia
Published: July 2022

Questa analisi nasce con la volontà di indagare alcuni nuclei filosofici espressi dalla poetica di Anna Maria Ortese. Nel caso della scrittura ortesiana, infatti, si dovrà parlare di un ragionamento di carattere etico, politico e teologico che in nessun caso prescinde dalla produzione letteraria, ma al contrario nasce e si sviluppa proprio in seno alla fiction. Dunque si è scelto di leggere Le Piccole Persone, raccolta di lettere, articoli e piccoli saggi, in stretta connessione con esempi di narrativa. A tale proposito, si è individuato ne L’Infanta Sepolta, opera meno conosciuta rispetto ai romanzi, un interessante case study capace di offrire un punto di vista privilegiato sulla poetica dell’autrice, di cui la novella rende manifesti alcuni tratti salienti; fra tutti, un ricorso al meraviglioso, che si fa portatore di contenuti simbolici e semantici poiché luogo di espressione di un’alterità che conserva la propria intraducibilità. Il lavoro vuole quindi dimostrare che la cifra irriducibile del meraviglioso ortesiano incarna un pensiero critico profondamente complesso, il quale mostra affinità con la riflessione delle filosofe e teologhe novecentesche (Simone Weil, Edith Stein), ma anche con la tradizione mistica (soprattutto Teresa d’Avila). Attraverso una poetica così organizzata, l’autrice riesce a sondare con potenza e originalità le principali questioni del Novecento: il male, la storia, la cosificazione, lo sfruttamento, i rapporti fra umano e non umano, la distruzione dell’altro.

Objective: In this study, we explored the characteristics of moral disengagement in sport and its mediating role in athletes' goal orientations and their attitudes towards doping We enrolled 203 athletes in the study. Methods: The Task and Ego Orientation in Sports Questionnaire,
Moral Disengagement in Sport Scale and Performance Enhancement Attitude Scale were used to assess athletes' goal orientations and attitudes toward doping. Results: Our findings revealed that: (1) male athletes' scores for moral disengagement were significantly higher than those of female
athletes; and (2) moral disengagement completely mediated the relationship between ego orientation and attitude towards doping, and partially mediated the association between task orientation and attitude towards doping. Conclusions: Changing the moral cognition and lowering the level
of moral disengagement in athletes may be important issues to include in anti-doping education.

Objectives:Our objective was to analyze changes in lifestyle patterns of Chinese college students at home during the COVID-19 outbreak.Methods:According to a structured online questionnaire covering socio- demographic information, anthropometric data, and changes in food intake, physical activity, and sleep during the COVID-19 outbreak, the relationships between the above data before and during the outbreak were analyzed.Results:Among the 781 participants, 38.5% had significantly increased their total food intake and 29.1% had significantly decreased their physical activity. Overall, 44% of participants reported weight gain. The average weight gain was 0.7±2.5 kg. The main causes of weight gain were increased food intake (p < .001), decreased physical activity (p < .01), and an excessive increase or reduction in sleep duration (p < .024).Conclusion:During the COVID-19 outbreak, college students' food intake was found to be increased and physical activity decreased; sleep duration was irregular, and all these factors influenced weight gain.

Objectives:Past studies show that vibration can stimulate muscle activity and improve muscle performance. However, further verification is needed on the effects of different vibration frequencies combined with different muscle strength exercise intensities on EMG activity and skeletal muscle hemodynamics.Methods:We recruited 27 male college athletes for 40%, 60%, and 80% maximum voluntary contraction (MVC) tests at the vibration frequencies of 0 Hz, 10 Hz, 20 Hz, and 30 Hz. We collected EMG activity signals using wireless EMGs and skeletal muscle hemodynamic parameters using a near-infrared spectrometer.Results:At an 80% MVC intensity of the rectus femoris, the mean, peak, and area of EMG at 30 Hz were significantly increased, compared with those at 0 Hz. At a 40% MVC intensity with vibration frequencies of 10 Hz, 20 Hz, and 30 Hz, the HHb of skeletal muscles was significantly increased, while the O2Hb and TSI were significantly decreased, compared with those at 0 Hz.Conclusions:We conclude that high frequency and strongly vibrated muscle strength exercise can improve EMG activity, while vibration and low-intensity muscle strength exercise could increase the oxygen consumption of skeletal muscles.

Den tvungne digitalisering af undervisningen under corona-nedlukningerne har rejst spørgsmål om, hvorvidt, og i så fald hvordan, erfaringerne fra denne tid skal efterlade et aftryk på fremtidig undervisning. Både danske og internationale undersøgelser peger på, at organisatorisk understøttelse er vigtig, hvis en evt. udvikling skal være bæredygtig. Her fremhæves bl.a. en styrkelse af underviseres tekniske kunnen og selvtillid (erfaring) samt anerkendelse og belønning af digitale undervisningsinitiativer. Denne artikel undersøger, hvad undervisere selv finder vigtigt, og om der er en relation mellem, hvad underviserne fremhæver og deres erfaringsniveau, baseret på fritekstssvar fra universitetsundervisere indsamlet i forbindelse med evalueringer på Københavns Universitet i hhv. efteråret 2020 og foråret 2021. Via en epistemisk netværksanalyse undersøges forbindelser i svarene mellem organisatoriske behov fordelt på undervisernes selvopfattede erfaringsniveau. Artiklen finder, at behovene for organisatorisk understøttelse ændrer sig alt efter erfaringsniveau, men at barriererne samtidigt er tæt forbundet, ligegyldigt hvilken erfaring man har.
Expanding possibilities for student participation in online learning environments for practice-based teaching

Developing primarily practice-oriented university courses for an online format challengespedagogical ideas about learning communities, participation, and involvement in learningsituations. Here, we report on a didactic design experiment, the aim of which was to design anonline learning environment that supported practice-based learning and in which possibilities forparticipation were strengthened and expanded. The experiment was conducted during a 14-weekuniversity course on co-design, in which the teachers designed different digital tools and learningactivities to strengthen the students’ feelings of belonging and community and student-to-studentinspiration. The topics discussed in this paper include how to rethink teaching practices in relationto online digital learning spaces and—a new practice that emerged from the design experiment—how to create “in-between spaces.” These spaces can be considered slow spaces that supportreflection and discussion, are less exposed, and can be created within and between lectures.
WORKING BY THE NUMBERS
Authors: Schmidt Cecilie Ullerup
Published: July 2022

The performance artists Florian Feigl and Fjóla Gautadóttir engage with production conditions of artistic work through their ways of managing time in performances. Informed by Marxist and feminist theories on affective and reproductive work, and with references to the history of performance art, I demonstrate how, contrary to myths of inspiration and virtuosity, production conditions co-create artistic authorship. Thereby, I reexamine what traditionally is termed as the aesthetics of production. An aesthetics of production is, I suggest, not about natural talent and originality of the soloist artist genius but is founded on the interdependency of life and work, and what enables the artist to do work. Feigl and Gautadóttir’s performances include what has been excluded as disturbances by idealist aesthetics of production: the sociality, temporality and economy of the artistic work. By proposing a feminist-materialist aesthetics of production, I claim that the artist’s work is not only working by the numbers of the present production conditions, but is also performing and intervening within the infrastructures of art.
WHY PRESERVE?

Published: July 2022

Our culture of appreciation of old buildings today is a product of the heritage culture of the (broadly speaking) eighteenth-century Central European (white, male, educated) upper class. While we find it pleasant and historically informative to have buildings well preserved, we find the absence of critical questioning of the practice surprisingly absent, although we observe an increasing number of academic discussions in the field of heritage studies, informed by decolonisation, climate change activism, and sustainability issues. Critical artistic practices have too been venturing into heritage and memory politics. The extensive costs of preserving old architecture raise eyebrows mainly only in the far- and alt-right circles, but as late reactions by parts of the global community, such as the attacks on statues as part of the Black Lives Matter movement, signal, there might be a change coming regarding our relationship to the built material past. We offer a reading of the history of the phenomenon, which will make it easier to, first, see it as an ethnic and class construct, and then sketch out a new perspective on its metaphysics, from memory to identity, to discourse. We include voices external to the world of heritage­­ – one that is still run by a privileged group that often claims to speak for others, and whose aims and practices are often, at least for now, accepted by others. We then proceed to discuss what kind of a role a curatorial approach could have in questioning and rethinking the idea of preserving.
MUSICAL COMPOSITIONS AND FRACTURES
Authors: Ahvenniemi Rebecka Sofia
Published: July 2022

“Each and every important work of art leaves traces behind in its material and technique,” Theodor W. Adorno postulates in Aesthetic Theory, as he describes the way a composition is both a result of its own time and reacts critically to the time it belongs to. This quote demonstrates a reversal: rather than merely an expression or an outcome of an artist’s idea, art itself is regarded as a source for change. The work may come to affect its own tools and materials and the social space around it. The primary question of this article is: what is it in musical composition that leaves the traces? This article attempts to move the focus away from discussion of finished works, and instead, depict how composition as a discipline engages in dialogue with its handcraft, historicity, and surrounding social world. I call this aspect of composition that possesses critical potential a lingering reflection. Slow and heteronomous in its nature, it presents a counterpoint to ideas that seem solid, are easily accessible and unquestioned.
MOVING ARCHITECTURE
Authors: Somhegyi Zoltán
Published: July 2022

One of the primary and most typical features of a piece of architecture is its stability, its fixed and anchored state. It is therefore surprising and, at the same time, aesthetically inspiring and intellectually exciting when buildings are moved. In the present study I examine the agency of transportation and the aesthetic consequences of such translocations in three art projects. First, I analyse the work of the Norwegian Marianne Heske, the Georgian Vajiko Chachkhiani, and the Finn Anssi Pulkkinen. I lay out the aesthetic implications of the transformative decontextualization caused by the relocation of the original structure. In the second part of the paper, I present the main aspects that connect these otherwise different projects and explain why the complex and costly transportation of these pieces of architecture is relevant and justified.
