Research aimed at the development and implementation of new digital methods and intelligent systems that allow improving the diagnostic process, increasing the reliability of determining the functional characteristics of agricultural tractors in an online mode is an important and relevant component of technologies and tools for servicing agricultural machinery. The paper presents the results on the justifi cation and development of an intelligent system for diagnosing machines based on the interaction of a neural network. The advantage of this diagnostic system is the ability to maintain the working condition of agricultural machinery, in case the processes of diagnosis and analysis of the obtained data are automated. The use of an intelligent tractor diagnostic system provides for the determination of not only the cause of failure by the controlled parameters, but also the effi ciency evaluation of the machine as a whole. It is established that one of the ways to increase the effi ciency of using agricultural machinery is the non-contact determination of the parameters of the technical condition of equipment through the modernization of the technology for monitoring the technical condition of machines and the quality of work on the basis of the introduction of modern intelligent and telemetric systems.

Published: May 2021

Applicability of coconut husk char in heavy metal removal was examined in the study. The surface morphology and elemental compositions of the char was investigated with SEM-EDX machine. Heavy metals sorption on 100 g of the char dosage was studied under five different contact times in the column experiment. Isotherm and kinetic models were the probing tools for biosorption mechanism prediction. Results indicated removal efficiency for chromium, cobalt, cadmium, aluminum and arsenic at 60 mins contact time were 72, 80, 86, 89 and 100 % respectively. Contaminate removal depends on metal involved and sorption contact time. Adsorption data are fitted well into Freundlich isotherm model (R2 > 0.92). Pseudo kinetic second order well described the adsorption process, with most R2 values ≥ 0.94. Coconut husk char is an effective biosorbent in sequestration of arsenic, cadmium, aluminum and cobalt in contaminated surface water.

Published: May 2021

This paper is aimed at designing a locally fabricated fiberglass parabolic antenna as a replacement for a metallic fabricated parabolic antenna. They are coated with a thin film of aluminum dust to enhance reflectivity since electromagnetic radiations do not travel deep in a conductor. This reduces the thick mass of metal usually used for constructing metallic parabolic antenna leading to a reduced cost of production. It incorporates a Low Noise Block (LNB) Converter comprising of amplifiers and frequency down converter. Metallic parabolic antenna contributes more to signal loss by reflecting radio waves. The Parabolic antenna is designed to receive microwave signals in the K-band with the down converter converting it to very high frequency (VHF) and ultra-high frequency (UHF) employing the super-heterodyning principle. The study shows the design and installation of a low-cost parabolic antenna in the rural community in Nigeria. The designed parabolic antenna is used to receive a signal with the center frequency of 11.3GHz and signal strength of 60%. The economic viability is that fiber-glass Parabolic antenna can replace the metallic fabricated ones.

Published: May 2021

The paper presents the results of experimental study of the adsorption properties of the combined sulfhydril collecting reagent –a mixed solution of sodium diethyl-dithiocarbamate (DEDTC) and oxypropyl diethyl-dithiocarbamate ester (OPDTC) towardschalcopyrite and arsenopyrite with a view to its application as a selective collector of Au-containing sulfide minerals in flotationof complex refractory ores. Combined diethyl-dithiocarbamate solution (DEDTCc) incorporated a fixed content of anionic andnon-ionic components (DEDTC:OPDTC = 1:1) and occurred variable hydrophobic effect on the surface of the basic gold-bearingsulfide minerals – chalcopyrite and arsenopyrite.The mechanism of adsorption of the components of combined collector on the surface of chalcopyrite and arsenopyrite was identifiedto form characteristic molecular shape of adsorbed collector convex neoplasms and sinter chemically adsorbed film of thereactant, which is firmly anchored on the surface. The newly formed phase of the adsorbed reagent did not dissolve in water at asubsequent washing. In this case, the phase of nonionic ester OPDTC was partially removed by water and the residual adsorbeddroplets changed their shape and became flatter. By X-ray microanalysis C and O bands relating to the structure of the combinedDEDTCc were identified on the surface of arsenopyrite and chalcopyrite. The original technic for analyzing the liner dimension ofsurface images with an application of scanning laser microscopy and the software of the Analyzer was developed and the authorssucceeded to provide a quantitative evaluation of the adsorption of DEDTCc on the surface of chalcopyrite and arsenopyrite.

Published: May 2021

The main area of coal application is energy production. During such stages as min-ing, transporting, treatment, storing and processingof coal, a large number of small products are formed, such as screenings, spills, sludges, etc. Such products are not usedand significantly pollute the environment. Meanwhile, after agglomeration, they can eas-ily be used for the production of thermalenergy. Of all the known agglomeration meth-ods, briquetting is most suitable. The technology of obtaining flammable briquettesbased on coal is developed. A technology has also been developed to produce fuel bri-quettes from coal slurries and paper waste.The use of coal slurries and paper waste as binder materials makes it possible to obtain a fuel pellet that is simple in production andcomposition and at the same time allows to utilize coal and paper wastes. The technolo-gy of obtaining fuel extrudates (briquettes)from wood and shale wastes, as well as wood, shale waste and sludge was developed. Thus, technologies have been developed toproduce fuel briquettes from various types of low-demand carbon-containing materi-als for domestic use.

Authors: Emilly Kamusiime  , Douglas Sheil
Published: May 2021

Relatively little is known about the diversity, distribution, and community ecology of parasitic plants in the forests of equatorial Africa. We examined mistletoes in the mountain forests of the Bwindi Impenetrable National Park in Southwestern Uganda. We recorded 1,496 individual mistletoes in 64 0.1-ha plots (6.4 ha total), evenly distributed between open (forest-edge) and closed (forest-interior) locations and spanning an elevation range of 1160 to 2607 m above sea level. These mistletoes included 21 species, seven genera and two families and were recorded on 542 host trees comprising 45 tree species. Overall, mistletoes were more common in open than in closed conditions (356 ha-1 versus 129 ha-1). The most abundant mistletoe species was Englerina woodfordioides (Schweinf. ex Engl.) Balle (328 records) followed by Viscum fischeri Engl. (316 records). Six mistletoe species were recorded just once. Harungana madagascariensis Lam. ex Poir. hosted the greatest diversity of mistletoes with nine species, while Maesa lanceolata Voigt hosted eight. Chao’s estimator indicates that mistletoe species richness across the whole forest likely exceeds 40 species which would be over ten percent of the mistletoe taxa known from the continent. The overall diversity and density of mistletoes appears high when compared to reported surveys from elsewhere. Mistletoes add significant botanical diversity in this forest and likely make a substantial contribution to its ecology.

Published: May 2021

Mastocytosis is a heterogeneous group of rare diseases related to the clonal, neoplastic proliferation of morphologically and immunophenotypically abnormal mast cells, that accumulate in one or more organ systems. Their pathophysiology is dominated by activating mutations in C-Kit (Stem Cell Factor receptor). Several pathological forms have been described ranging from isolated cutaneous mastocytosis affecting mainly children, to aggressive systemic mastocytosis described mainly in adults with bone marrow involvement. According to the WHO 2016 classification of hematological malignancies, systemic mastocytosis appear as a new entity of "myeloid neoplasms and acute leukemias" that combines cytology (abnormal mast cells) with other genetic and molecular criteria. We describe through this observation the practical side of hematological cytology in the diagnostic orientation of this serious, rare and underestimated pathology.

Cadmium (Cd) is a toxic heavy metal and one of the most important environmental pollutant that is derived from agricultural and industrial sources. Boron (B) is a metalloid that has beneficial physiological effects on the metabolism of animals and humans. This research is aimed at investigating the effect of calcium tetraborate (CaB4O7) on the ovalbumin levels of quail’s egg and some egg quality traits in laying quails exposed to Cd. For this purpose, one hundred twenty Japanese quail 6-week-old were randomly divided into 4 groups (5 replicates each). During the 8 weeks, quails were fed a basal diet (control) and basal diet supplemented with Cd (100 mg of CdCl2), CaB4O7 (300 mg of CaB4O7), and Cd + CaB4O7 (100 mg of CdCl2 and 300 mg of CaB4O7). A total of 160 eggs including 40 eggs from each group were collected for assessment of the quality of the egg and the ovalbumin level of the eggs. Compared with the Cd group, supplementation of Cd + CaB4O7 increased the egg weight (P < 0.01). Results of this study indicated that dietary supplementation with Cd or CaB4O7 was not affected significantly albumen pH, yolk ratio, and yolk color (P > 0.05). Regarding the egg quality, the significant effect of Cd or CaB4O7 (P < 0.01) was found in shape index, yolk weight, albumen weight, and yolk pH. The dietary combination of Cd and CaB4O7 led to the greatest increases in albumen ratio (P < 0.01). The Cd group had the highest ovalbumin level, while CaB4O7 and Cd + CaB4O7 groups had the same ovalbumin level. The findings of this study revealed that provided new insight into the toxicity of the Cd on ovalbumin level and some egg quality traits and CaB4O7 could be used as a potential strategy to ameliorate Cd toxicity.

Published: May 2021

Water quality is a worldwide concern especially water for human consumption. Regular monitoring and tools should be developed, to ensure continuous assessment of the level of concentration of chemical constituents prevalent in water. This will guide against health dangers and risks associated with water of low quality. The research focus on using semi-variogram models to measure the degree of spatial dependency of sampled boreholes for prediction of the concentration of water quality parameters at un-sampled locations because of the cumbersome nature of assessing the whole boreholes in Benin City. One hundred and ten (110) different domestic boreholes were systematically sampled and analyzed in laboratory for determination of the concentration of some chemical water quality parameters which include Electrical Conductivity (EC), Total Dissolve Solids (TDS), Bicarbonate (HCO3), Sodium (Na), Potassium (K), Calcium (Ca), Magnesium (Mg), etc. Laboratory examination of boreholes water quality parameters were carried out in wet and dry seasons. Geographical locations of sampled boreholes were also determined. The obtained experimental results were utilized in investigating the spatial structure of the boreholes using semi-variogram models which include spherical, exponential, Gaussian etc. Exponential model was the most fitted model. The borehole water quality parameters exhibited high degree of spatial dependency in EC, TDS, HCO3, Na, K, Ca. Mg, Cl, P, and NO3 in both seasons with ratio < 25% therefore, interpolation technique can be employed to produce spatial variation quality map of boreholes in Benin City as a monitoring technique to detect contamination or changes in water quality.

The article discusses the causes of problems of the educational system of Ukraine. It is noted that the main reason is the lack of interconnection between educational institutions of various levels of training and enterprises. This problem can be solved by combining the subjects of the educational system in clusters. The main tasks of the cluster are highlighted: providing high-quality school and university education, creating a system for training future specialists, attracting business partners to train personnel, and increasing the scientific and technical potential of the country's economy as a whole. Various definitions of the concept of “Educational cluster” are analyzed, two main approaches to the interpretation of the concept are identified. The main objectives of the formation of educational clusters are identified. It is noted that the clustering process in Ukraine is slow, despite the fact that the world experience of the last three decades indicates a rapid rise in leading sectors of economy through development of socially integrated systems.
Cossack pedagogy – characteristic features
Authors: Borisenko N. , Vorozhbit-Horbatiuk V.
Published: May 2021

The article is devoted to disclosure of the characteristic features of Cossack pedagogy. Attention is focused on the fact that education in the context of the chosen topic is understood as a specially organized by interactions among educators and pupils to understand the spiritual and material culture of the nation, the formation of national consciousness and the achievement of spiritual unity of generations.

The identity of Ukrainian national psychology in the article is determined by the basis of Cossack pedagogy. Among the factors, a large number of male children were identified, who constantly replenished the ranks of Sich’s pupils, abandoned, or abducted in campaigns against рeople of other faiths, as well as the high cultural level of the Cossack state. The authors noted that education dynamically developed through the formation of Cossack schools of various types. The goal of these schools was to educate and form a diversified personality through the development of martial arts, combat training through dance, teaching singing, reading and writing, the God's law. Graduates of Sich schools could continue their studies at the Kiev-Mohyla Academy.

It is stated that Cossack pedagogy synthesized humanism and deep democratism of the Ukrainian worldview, relied on national traditions, rich experience of self-government and the level of formation of justice in conventual and fraternal schools.

The article focuses on the global significance of Cossack pedagogy. As the most famous example of Cossack martial arts, the authors highlighted the Cossack Hopak dance.

It is indicated, that individual Cossacks by special exercises achieved an incredible effect when the body seemed to play (in this case, the enemy’s painful hits were not felt). Cossacks were able to instantly concentrate internal energy in that part of their body where the enemy’s blow was directed. Such phenomena are inherent in martial arts, for example, the art of Tibetan monks of the cathode and the "school of the iron shirt" in kung fu and karate.
On correction and improvement of professional Ukrainian language of the teachers
Authors: Telpukhovska Y.
Published: May 2021

The article addresses the need for special efforts to resolve the issue of  correction  of teachers' professional Ukrainian language in the  bilingual and Russian-speaking regions of Ukraine. The article also provides the materials to prevent and overcome the widespread language mistakes of the teachers.

The most widespread phonetic and orthoepic mistakes in the professional speech of a teacher are considered, namely: incorrect pronunciation of words, incorrect pronunciation of certain Ukrainian sounds and sound combinations, stunning of the consonants in the absolute end of the word and in the middle of the word before the deaf, etc. in Ukrainian words.

The causes and types of lexical mistakes in teacher's speech are illustrated. There is a large number of dangerous phrases from the point of view of teachers and students observing the correct language.

The most common grammatical mistakes are emphasized, namely: absence of an exclamation mark for the students' names when addressing them, incorrect spelling of Ukrainian masculine surnames, inattention to differences in management of word combinations etc.

The teacher must have a good command of the scientific terms of those subjects, which he teaches the basics, as well as the peculiarities of Ukrainian scientific style constructions. The article describes the numerous Ukrainian designs of the scientific style, which are used daily by the teacher in his professional speech and in which mistakes are often made.

The article concludes the importance of optimizing the teaching of professional speech to students-future teachers, as well as the need to organize work on the correction of speech in special training courses and advanced training of current teachers. The materials offered in the article can be used (with some correction) in the system of speech training of teachers-teachers of different specialties at all faculties of pedagogical colleges.

Authors: Dementieva T.
Published: May 2021

This article examines the process of forming the skills of dialogic speech of foreign listeners at the stage of pre-university training with the help of educational and speech situations. It is emphasized that the starting point when teaching spoken language should be a situation that is a standard form of communication. The case is in necessity to simulate educational and speech situations that would take into account the future frame of reference of students in the first year of higher education, in other words, within the educational and professional frame. The types of learning and speaking situations (duplicating, responding, prompting, pre-speaking, colloquial) highlighted on the basis of the stages of formation of speech skills are presented. All the names of educational and learning situations are conditionally submitted, according to the operations that foreign listeners need master in the process of solving them. The purpose of each type of learning and speech situation, that is, the skills that are formed in foreign listeners in the process of using this or that type of situation, as well as the conditions of their objectification: the degree of participation of the teacher and the task for foreign listeners. Examples of different types of learning and speaking situations are given, using the most common dialogic unities in speech, at different stages of the formation of speech skills. The conclusions about the expediency and effectiveness of the use of educational and speech situations, which help to overcome the juxtaposition of theoretical and practical stages of training, to provide a high degree of mastering of speech material, as well as to effectively use lessons during the teaching of dialogic speech of foreign listeners during the pre-university tutorial stage.

Published: May 2021

African Independence is a dynamic discussion of how African history shapes world events today. Africa has played a major role in human history, and it is impossible to understand the present condition of humanity, or our future without a consideration of Africa. Although Africa is often portrayed as a remote and impoverished area, remembered for the suffering of its people, it has played an important role in world history that is critical for understanding global events today. Tukufu Zuberi walks readers through the years of African independence through the present. The documentary discusses colonialism, the impact of the world wars, independence movements, the Cold War, ethnic conflict, terrorism, the health crisis, and more. The documentary weaves personal interview excerpts with people ranging from World War Two veterans, freedom fighters, to Heads of State into the arc of African and world history. Providing context for understanding events such as civil war, terrorism, and development aid, African Independence argues that it is impossible to understand our current world situation, or our future, without considering Africa. The award-winning documentary accompanies the book African Independence: how Africa shapes the world.

Os desafios impostos pela pandemia de Covid-19 no Brasil e em Portugal instigaram pesquisadores e alunos, para uma análise mais aprofundada sobre as condições de vida e as iniquidades da população. Trata-se de uma leitura crítica da realidade, a partir da conjuntura de crise sanitária, política e econômica, bem como seus rebatimentos para os grupos vulnerabilizados como mulheres, crianças e adolescentes, idosos, indígenas, Lgbts e classe trabalhadora. A pandemia escancarou as marcas sócio históricas das desigualdades e da pobreza, agravando as diversas vulnerabilidades sociais como a fome, o desemprego, a desigualdade de gênero, a negação de direitos, as diversas expressões das violências, que afetaram a saúde física e mental da população. Este período pandêmico tornou-se um tempo de reinvenções, pois além de acentuar as mazelas sociais e a precariedade do sistema de saúde pública e de assistência social; demonstrou a insuficiência das políticas públicas, agravadas pela calamidade pública, e pelo o desmonte neoliberal dos serviços públicos. A obra ressalta a importância de investimentos em estratégias articuladas de promoção da saúde, como via de acesso, as respostas mais saudáveis, no enfrentamento da problemática.

Široki pravni okvir propisanih kažnjivih ponašanja fizičkih i pravnih osoba tijekom pandemije bolesti COVID-19, prouzročene virusom SARS-CoV-2, omogućuje kažnjavanje sankcijama različite pravne prirode. U radu se razgraničavaju moguća kažnjiva ponašanja fizičkih i pravnih osoba u kontekstu pandemije između kaznenog, prekršajnog i upravnog prava. Autori najprije analiziraju odgovornost za kaznena djela širenja i prenošenja zarazne bolesti te krivotvorenja lijekova ili medicinskih proizvoda. Posebno se naglašava problem eventualne odgovornosti liječnika i drugih zdravstvenih djelatnika i zdravstvenih ustanova za nemogućnost pristupa zdravstvenim uslugama kao i njihovu odgovornost u vezi s prevencijom, dijagnosticiranjem i liječenjem građana. Zaključno, autori analiziraju široki spektar prekršajne odgovornosti i upravnopravnih mehanizama prisilnog izvršenja novčanih kazni.

Since the onset of the COVID-19 pandemic in March 2020, California has had more than 3.7 million confirmed cases of COVID-19 and over 62,000 total deaths. According to Statista, California has been the state with the most COVID-19 cases and deaths in the U.S. and has maintained that status for the majority of the pandemic. Recently, however, the case and death rates for the state have decreased drastically. For the week of May 3, California’s COVID-19 case load is approximately 5 per 100,000 residents, ranking it at the bottom of the list for case rates compared to other states in the country, down 98% from its peak; and deaths from COVID are down to 0.15 per 100,000 residents, down 95%. The state’s 7 day rolling average of new cases in 2020 remained well below 10,000 from March to early July, but sharply increased and exceeded 10,000 by August. Then, it decreased to the 4,000 range in the fall. From late November to mid-January, there was another rise, with the average reaching its highest recorded level at approximately 44,000 on December 22. After reaching its peak in December, it fell dramatically, to below 1,900 by early May. Consequently, the probability of contracting COVID as a resident in California is far slimmer today than it was just three months ago.

Motionwatch8 Wrist Actimetry Data Analysis: from ambulatory recording to real life monitoring.
Authors: delucca gianluigi
Published: May 2021

On the National Sleep Research Resource (NSRR) platform, there's a year's worth in real-life wrist actigraphy data using a Motionwatch8. The data analysis suggested in this paper reveals a data structure that allows the design of parameters to be used in real life monitoring and may drive the developments of devices. The analysis is totally data driven and connects in a quantitative way the wrist movements (time base seconds) to the circadian rhythms (time base days). A simple example of parameters is described
Diversity and violence during conflict migration: The Troubles in Northern Ireland
Authors: Adida Claire , Brown Joseph , McCord Gordon C. , McLachlan Paul
Published: May 2021

The effect of diversity on violence is ambiguous. Some studies find that diverse areas experience more violence; others find the opposite. Yet violence displaces and intimidates people, creating measurement challenges. We propose a novel indicator of diversity that circumvents these problems: the location of physical structures at disaggregated geographical levels, and introduce this solution in the context of the Troubles in Northern Ireland. Our data reveals a curvilinear relationship between diversity and violence with the steepest increase at low diversity, driven by an increase in violence when our proxy for Catholic proportion of the population rises from 0 to 20%. These patterns are consistent with a theory of group threat through exposure.
Distributed Acoustic Sensing for Near Surface Imaging from Submarine Telecommunication Cable: Case Study in the Trondheim Fjord
Authors: Taweesintananon Kittinat , Landrø Martin , Brenne Jan Kristoffer , Haukanes Aksel
Published: May 2021

Distributed acoustic sensing (DAS) transforms submarine telecommunication cables into densely sampled seismic receivers. To demonstrate DAS applications for seismic imaging, we use an optical cable on the seafloor in the Trondheim Fjord, Norway, to record seismic data generated by a controlled seismic source. The data are simultaneously recorded by a towed hydrophone array and the fiber optic cable. Following our data processing methods, we can produce seismic images of the seafloor and underlying geological structures from both the hydrophone array data and the DAS data. We find that the DAS data and the hydrophone data have a comparable signal-to-noise ratio. Moreover, DAS images can be improved by using a seismic source that has sufficiently large energy within the frequency range matching the spatial resolution of DAS. The temporal resolution of the DAS images can be improved by minimizing the crossline offset between seismic sources and the DAS cable. The seismic images from DAS can be obtained to support geohazard analysis and various subsurface exploration activities.
Missing Pieces: Engaging Sociology of Disability in Medical Sociology
Authors: Mauldin Laura , Brown Robyn Lewis
Published: May 2021

Medical sociologists and sociologists of disability study similar topics but, because of competing or conflicting theoretical paradigms, tend to arrive at different conclusions, engage with different audiences, and pursue different directions for social change. Despite diverging trajectories over the past 20 years, however, there remains clear potential overlap between both subfields in the study of disability and untapped opportunities for cross-fertilization. Our purpose here is to place these literatures in conversation with each other. Toward this end, we identify major themes in the last 20 years of medical sociology scholarship, gaps with regard to disability in those themes, and possibilities (including methodologies) we see at the intersection of medical sociology and the sociology of disability that could address these gaps.
Statistical modeling of vignette data in psychology
Authors: Baguley Thom , Dunham Grace , Steer Oonagh
Published: May 2021

Vignette methods are widely used in psychology and the social sciences to obtain responses to multi-dimensional scenarios or situations. Where quantitative data are collected this presents challenges to the selection of an appropriate statistical model. This depends on subtle details of the design and allocation of vignettes to participants. A key distinction is between factorial survey experiments where each participant receives a different allocation of vignettes from the full universe of possible vignettes and experimental vignette studies where this restriction is relaxed. The former leads to nested designs with a single random factor and the latter to designs with two crossed random factors. In addition, the allocation of vignettes to participants may lead to fractional or unbalanced designs and a consequent loss of efficiency or aliasing of the effects of interest. Many vignette studies (including some factorial survey experiments) include unmodeled heterogeneity between vignettes leading to potentially serious problems if traditional regression approaches are adopted. These issues are reviewed and recommendations are made for the efficient design of vignette studies including the allocation of vignettes to participants. Multilevel models are proposed as a general approach to handling nested and crossed designs including unbalanced and fractional designs. This is illustrated with a small vignette data set looking at judgements of online and offline bullying and harassment.
Urban Analytics: History, Trajectory, and Critique
Authors: Boeing Geoff , Batty Michael , Jiang Shan , Schweitzer Lisa
Published: May 2021

Urban analytics combines spatial analysis, statistics, computer science, and urban planning to understand and shape city futures. While it promises better policymaking insights, concerns exist around its epistemological scope and impacts on privacy, ethics, and social control. This chapter reflects on the history and trajectory of urban analytics as a scholarly and professional discipline. In particular, it considers the direction in which this field is going and whether it improves our collective and individual welfare. It first introduces early theories, models, and deductive methods from which the field originated before shifting toward induction. It then explores urban network analytics that enrich traditional representations of spatial interaction and structure. Next it discusses urban applications of spatiotemporal big data and machine learning. Finally, it argues that privacy and ethical concerns are too often ignored as ubiquitous monitoring and analytics can empower social repression. It concludes with a call for a more critical urban analytics that recognizes its epistemological limits, emphasizes human dignity, and learns from and supports marginalized communities.
Class and Memory Activism
Authors: Hilmar Till
Published: May 2021

In this chapter, I call on memory scholars and activists to revisit the relationship between class and memory. Class, operating through the unequal distribution of both material and symbolic resources, has an inconspicuous, hidden, and tacit quality to it. Thinking through the contradictions posed by class, memory activists fighting for economic and racial justice can give voice to lived experiences of dispossession and bring structures of exploitation to light. The concept of moral economy, I suggest, provides a particularly rich theoretical and empirical repertoire to do so. The chapter identifies potential avenues for research on class and memory activism in four areas in which class is variously institutionalized in society: Generation, milieu, ethnicity and gender.
Wewnętrzna jawność postępowań rehabilitacyjnych z perspektywy oskarżonego i jego obrońcy
Authors: Sychta Katarzyna
Published: May 2021

The article touches upon the issue of internal transparency of rehabilitation proceedings and reinvestigations which take place following the annulment of the final judgment. Depending on the rehabilitation prerequisites, it is possible to obtain an acquittal or a judgment equal to an acquittal in three exceptional and appeal modes, i.e. cassation, revision and annulment with regard to persons who experienced repression on the grounds of their involvement in actions aimed at maintaining the independence of the Republic of Poland. The full inclusion of the defendant and their defender in the court proceedings guarantees that the efforts to expunge the defendant’s criminal record will be carried out in accordance with the rules of directness, contradictoriness, equality, orality, the right to defense and broadly understood rule of conscientiousness. This type of procedure upholds the possibility of voluntary participation of the defendant in proceedings aimed at establishing the probability or certainty of the emergence of grounds for employing exceptional appeal modes, while the restrictions, exclusion or expansion of the involvement of the defendant are regulated according to particular exceptions.
