“Conciudadanos que se fletan como bestias”. Experiencia y expectativa en las descripciones e imágenes de los cargueros de hombres en la Nueva Granada, 1851 y 1853
Authors: Urueña Calderón Juan Felipe
Published: December 2021

Objetivo: se analizan las metáforas y las imágenes con las que actores históricos como Santiago Pérez, José Caicedo Rojas, Ramón Torres Méndez y el pintor anónimo de la Comisión Corográfica comparan a los cargueros de hombres con animales de carga a mediados del siglo xix en la Nueva Granada. Se postula que estos actos visuales y lingüísticos, y los soportes que permiten su circulación, cristalizan y a la vez movilizan un conglomerado de estratos temporales con los cuales los actores, desde un presente incierto, interpretan el pasado y proyectan el futuro. Metodología: se analizan las imágenes, las metáforas y los soportes en los que estas circulan, con el fin de ver de qué manera son usados por los actores para expresar su experiencia histórica; se consideran en el contexto de sus trayectorias temporales y espaciales para dar cuenta de la especificidad de su uso en la Nueva Granada en la mitad del siglo xix. Originalidad: se usan imágenes y metáforas de la literatura de viajes y el costumbrismo, y los soportes que les permiten circular, para indagar por la experiencia temporal en el contexto de los debates sobre la semántica histórica. Conclusiones: se muestra que los actores no son meros receptores pasivos que repiten tópicos europeos, sino que son instancias de una red de circulación que capturan momentáneamente unos recursos visuales y lingüísticos para dar cuenta del modo como experimentaban su presente histórico.

Government policies by legitimizing the presence of the omnibus law on copyright work, socially and legally have an impact on labor and workers. The reason is that this controversial law is considered to be very detrimental to labor and workers. The purpose of this study was to analyze the extent to which social impacts were generated after the government legal sociological perspective of the work copyright omnibus law was passed. This study uses a qualitative approach and descriptive methods and is equipped with literature study data collection. The results of the study conclude that the sociology of law responds to the rejection of the omnibus law on work copyright done by workers and labor because it will have an effect on social impacts that have implications for demonstrations of labor and workers nationally.

Published: December 2021

The existence of local political parties in Indonesia is a tangible form of the existence of special autonomy in a certain area. The specificity of a certain area is regulated in the 1945 Constitution Article 18B paragraph (1). In addition, the formation of local political parties is one of the human rights in the political field, as stated in Article 28E paragraph (3) of the 1945 Constitution. The research method uses a normative juridical approach with secondary data and analyzed descriptively qualitatively. Based on research, Papua Province has the right to form political parties (see Article 28 paragraph (1) of the Papua Province Special Autonomy Law). However, the phrase "political party" is considered to have multiple interpretations, thus creating legal uncertainty. Through the decision of the Constitutional Court Number 41/PUU-XVII/2019, the legal uncertainty can be guaranteed by the Constitutional Court Decision. In the future, by looking at the background and real needs of the Papua Province, it is possible to form a Local Political Party in the Papua Province, considering the condition of the Papua Province as a special autonomous region.Partai politik lokal di Indonesia merupakan wujud nyata adanya otonomi khusus di suatu daerah. Kekhususan suatu daerah diatur dalam UUD 1945 Pasal 18B ayat (1). Selain itu, pembentukan partai politik lokal merupakan salah satu hak asasi manusia di bidang politik, sebagaimana tercantum dalam Pasal 28E ayat (3) UUD 1945. Metode penelitian menggunakan pendekatan yuridis normatif dengan data sekunder dan dianalisis secara deskriptif kualitatif. Berdasarkan penelitian, Provinsi Papua berhak membentuk partai politik (lihat Pasal 28 ayat (1) UU Otsus Provinsi Papua). Namun, ungkapan “partai politik” dianggap memiliki multitafsir sehingga menimbulkan ketidakpastian hukum. Melalui putusan MK Nomor 41/PUU-XVII/2019, ketidakpastian hukum dapat dijamin oleh Putusan MK tersebut. Ke depan, dengan melihat latar belakang dan kebutuhan riil Provinsi Papua, dimung­kinkan dibentuknya Partai Politik Lokal di Provinsi Papua, mengingat kondisi Provinsi Papua sebagai daerah otonomi khusus.

Authors: Wang Dan , Dong Xiaoqing
Published: December 2021

Gastrodin is one of the main active components of Gastrodia elata and has significant therapeutic value for various nervous system diseases. Its medicinal properties include smooth muscle relaxation, anti-necrosis, anti-aging, and anti-apoptosis effects. However, its possible effects on traumatic brain injury (TBI) are still unclear. In this study, the effects of gastroditin on TBI rats were investigated. The results proved that gastrodin had neuroprotective effect on TBI through alleviating brain deficits, decreasing brain water content, inhibiting neuronal apoptosis, and suppressing oxidative stress in brain tissues of TBI rats. Mechanically, gastrodin upregulated the expression of Nrf2 downstream proteins, suggesting the activation of Nrf2 pathway in brain tissues of TBI rats. In conclusion, gastrodin provided neuroprotection in TBI rats via Nrf2 pathway.
Comparing Bayesian Posterior Passing with Meta-analysis
Authors: Pritsker Joshua
Published: December 2021

Brand, von der Post, Ounsley, and Morgan (2019) introduced Bayesian posterior passing as an alternative to traditional meta-analyses.  In this commentary I relate their procedure to traditional meta-analysis, showing that posterior passing is equivalent to fixed effects meta-analysis.  To overcome the limitations of simple posterior passing, I introduce improved posterior passing methods to account for heterogeneity and publication bias.  Additionally, practical limitations of posterior passing and the role that it can play in future research are discussed.

Published: December 2021

In this work, we have synthesized copper oxide nanoparticles using Iranian violaceae flower extract and explored its biological activity. Green synthesis has emerged as a reliable, sustainable and ecofriendly protocol for synthesizing a wide range of nanomaterials and hybrid materials. In this paper, we report the synthesis of Copper oxide nanoparticles by a simple biological route using the extract of Iranian violaceae flower and CuSO4, 5 H2O was used to synthesis the copper oxide Nanoparticles. The synthesized copper oxide nanoparticles were characterized using UV–visible spectroscopy, FTIR spectroscopy, FESEM, EDAX, and XRD techniques. UV –Visible analysis shows a characteristic peak around 266 nm for copper oxide nanoparticles and which is characteristic copper oxide nanoparticles. FTIR spectroscopy was used to characterize various capping and reducing agents present in the plant extract responsible for nanoparticle formation. The surface morphology was characterized using FESEM. The EDAX and XRD pattern suggested that prepared copper oxide nanoparticles were highly pure. The average particle size was calculated as 78.5 nm and α-copper oxide for all diffraction peaks (JCPDS card No. 41-1449) using the XRD technique. Our finding also support the synthesis of CuO NPs from Iranian violaceae flower sources due to relative abundance of plants for the production of reducing and stabilizing agents required for CuO NPs synthesis, potential efficiency of plant biomolecules in enhancing the toxicity effect of CuO NPs against microbes, prevention of environmental pollution due of nontoxic chemicals and degradation effectiveness of CuO NPs synthesized from plant sources. Furthermore, this study provides useful information on the rapid synthesis of CuO NPs with desired properties from plant extracts. Copper oxide NPs can have a good candidate for different applications.

The article deals with the problem of weak integration of Russian universities into the real economy. This is one of the most pressing problems of the Russian university system. The purpose of the article is to develop a specialized pilot checklist "Towards business: a model for integrating higher education and the real sector of the economy" and to demonstrate the prospects for its use in regional universities. The general hypothesis of the research is to test the feasibility of creating and using such checklists to help Russian universities in restructuring their organizational models in the direction of strengthening practice orientation. It is shown that at present the market for a new information and analytical product – checklists – is in its infancy and is evolving in several directions. Firstly, it becomes more complicated: the number of constituent documents increases, the number of questions increases, etc. Secondly, the forms of their implementation are being improved: chargeable, bonus, free, by subscription, with an additional package, etc. Thirdly, different algorithms for their application appear: straightforward replication of a standard document, provision of a checklist with subsequent in-depth research and recommendations in relation to a specific customer, the possibility of choosing an additional service for expert assessment, creation and implementation of mobile applications for prompt updating of checklists, and etc. All of this allows the new methodological tool to find application in the higher education system. The article examines some typical examples of the new trend emerging in Spain, Croatia, Great Britain, the USA and Russia, as well as pan-European and Latin American initiatives. The methodology of the author's checklist "Towards business" is based on taking into account the world experience of integrating universities and enterprises in a compact form: an instruction document and a cover note. There have not yet been effective prototypes of the developed checklist in Russia. Cases of using the pilot checklist for reorganizing the model of work of universities in the Kamchatka Territory, the Republic of Dagestan and the Lipetsk Region confirm the general hypothesis of the article.

Published: December 2021

The relevance of the research topic is due to the need to strengthen and expand the technological transformation of the Russian economy, which should contribute to the growth of high-tech products production and increase the competitiveness of domestic manufacturers in the world market. The hypothesis of the study is that the component features of the intellectual capital of the industrial region determine the predisposition/absence of predisposition of its economy to make a transition to a new dominant technological structure. The purpose of the scientific research is to identify the types of intellectual capital and which of them form the predisposition of regions to the technological transformation of their economies. During the study, the following tasks were solved: structural elements of intellectual capital that affect the innovative and technological development of the region, namely: education, are justified; innovative competencies; innovative skills; altruism; cognitive and non-cognitive competencies; sensitivity to change and adaptation to technological changes. Extractive, mono-inclusive and multi-inclusive type of intellectual capital of industrial regions, corresponding to the fourth, fifth and sixth technological framework, respectively, is disclosed. A methodology for estimating intellectual capital, which determines the dominant technological structure of the economy of the industrial region, has been developed on the basis of the use of the matrix method and Frobenius norms, which make it possible to conduct research over a long-time interval taking into account the dynamic trends of the main capital elements. The testing of the author's methodology revealed that such territories as Kemerovo Region, Nizhny Novgorod Region, Perm Territory, Republic of Bashkortostan, Republic of Tatarstan, Sverdlovsk Region, Udmurt Republic, Chelyabinsk Region, Chuvash Republic and Yaroslavl Region have intellectual capital for further technological development of the region's economy. The novelty of the obtained results lies in the development of a typology of regions, which enables one to identify the territories most prone to further technological transformation of the economy in the context of types of intellectual capital. The practical significance of the results obtained lies in the possibility of their use by authorities as a tool for developing a strategy for industrial development and structural adjustment of the economy of industrial regions.

The higher education system makes it possible to accelerate the process of transition of the economy and society to a sustainable direction of its development by forming a new ecological worldview among the younger generation and minimizing future ecological and economic damage to the environment of the region in which the university is located. Nowadays, the pace of the implementation of sustainable development principles in the operational and educational activities of Russian universities remains low, which affects the level of environmental and economic security. The purpose of this study is to identify barriers and prospects for the implementation of sustainable development principles in Russian universities, as a factor of increasing the level of environmental and economic security, using the case of Ural Federal University. The authors analyzed the university's development program, its implemented activities in the field of ecology and sustainable development, its eco-oriented activities, and evaluated the university using the UI Green University Metrics methodology in order to determine its potential position in the green universities ranking. SWOT analysis was carried out to combine the results obtained and to identify the barriers to the implementation of the sustainable development principles and the barriers to increasing the level of environmental and economic security. Promising directions for the development of the university for the coming years were also identified within the framework of the new concept. The main barriers are the lack of an official program of sustainable development of the university, appropriate administrative and economic management tools and targeted state support. In order to stimulate the university's transition to a new concept, the development of a specialized information resource and improvement of the solid municipal waste management system are proposed. A list of economic, organizational and administrative tools for managing sustainable development is also formulated. The implementation of these measures could not only form the foundation for the successful implementation of the sustainable development principles at Ural Federal University but would also increase the university's potential position in the UI Green University Metrics rating and would have a positive impact on the level of environmental and economic security.
Uma agenda para reinvenção da biblioteca universitária
Authors: Strehl Leticia
Published: December 2021

Se existe fato amplamente conhecido é o de que a tecnologia da informação transformou por completo nossas vidas nas últimas décadas. Esse ensaio apresenta uma agenda constituída de 8 ações para a reinvenção das bibliotecas universitárias considerando o impacto dessas mudanças não apenas na infraestrutura de produtos e serviços, mas também para considerar a revisão estratégica da missão de acesso às coleções da biblioteca tradicional em dois níveis: o acesso à informação para além de suas próprias coleções e a formação de competências informacionais. Essas missões serão identificadas no ensaio como uma reinvenção da biblioteca tradicional para passar a abrigar dentro de si, respectivamente, mais duas bibliotecas: uma tecnológica e outra educadora. As ações apresentadas na Agenda buscam mostrar como essa reinvenção é necessária para o efetivo cumprimento da função social das bibliotecas universitárias. A oitava e última ação faz um chamamento dos bibliotecários para a “Revolução”, em um processo da gestão participativa, que precisa ser iniciado de dentro para fora, tendo em vista a precarização de políticas públicas de investimento em bibliotecas. Conclui com um convite de compartilhamento de “Agendas para Reinvenção de Bibliotecas Universitárias” como um exercício de gestão estratégica e de ciência aberta pela disponibilização do ensaio em um repositório de pré-prints para revisão aberta dos pares.

Published: December 2021

Eski Halfeti merkezinde Osmanlı döneminden kalan başlıca vakıf eserlerden biri Birecik baraj gölü kıyısındaki Halfeti Ulu Camii’dir. Tanzimat döneminde Rumkale’nin harabe hale gelmesinden sonra Rumkale Kazası’nın merkezi Halfeti’ye taşındı. Aynı süreçte inşa edilen Ulu Cami, Halfeti kasabasının gelişiminde önemli bir yere sahip oldu. Merkez Camii de denilen yapı, Halfeti’de yapıldığı tespit edilen ilk camidir. Mevcut çalışmalarda caminin vakfiyesi ve camiye dair diğer arşiv kayıtları göz ardı edilmiştir. Yapının kitabesi kırık olduğundan inşa tarihi hakkında farklı değerlendirmeler yapılmıştır. Ancak Halfeti’nin tarihi ve mimarisi için önem arz eden bu vakıf eserin tam olarak ne zaman inşa edildiğini tespit etmeye ihtiyaç vardır. Bâni Latifzâde Mehmed Efendi’nin ve tamir kitabelerinde ismi geçen diğer kişilerin kim olduğu açığa çıkarılması gereken diğer hususlardır. Arşiv kayıtlarını esas alan bu çalışmanın amacı; Halfeti Ulu Camii’nin; bânisi, kitabeleri, onarımları, vakfiyeleri ve 19. yüzyıla ait fotoğrafları üzerinden Osmanlı dönemindeki tarihi sürecini etraflı şekilde ortaya koymaktır.

Published: December 2021

O Investimento na vida pessoal (IVP), remete-nos para a valorização e atribuição de objetivos de vida ao ser humano, em todos os seus atributos e fases de vida contribuindo positivamente para o envelhecimento ativo. Assim, o objetivo do estudo visa avaliar níveis e determinantes do Investimento na vida pessoal percecionado por um grupo de idosos institucionalizados. Trata-se de um estudo não experimental, transversal, descritivo-correlacional de caráter quantitativo, que foi realizado numa amostra de 270 pessoas idosas a residir em Instituições, na zona Centro e Norte de Portugal. Foi utilizada uma bateria de escalas que composta por: um protocolo de caraterização sócio demográfica, o índice de Barthel, a Escala de Apgar Familiar, e uma Escala de Avaliação de Investimento na Vida Pessoal (EAIVP). Os resultados mostraram que a perceção dos idosos sobre o investimento na sua vida pessoal se distribui de uma forma relativamente equitativa por três níveis. Assim 36,3% perceciona o seu investimento como elevado, 30,7% entende-o como moderado e 33,0% baixo. Os homens tendem a avaliar o IVP de uma forma mais positiva que as mulheres. A análise dos fatores determinantes revela que os idosos que sentem ter investido mais na vida pessoal são os que possuem maior escolaridade (p=0,047), que apresentam maior independência na realização das AVD (p=0,035) e que percecionam maior funcionalidade familiar (p=0,022). As evidências encontradas no estudo revelam que os níveis de investimento na vida pessoal percecionado pelos idosos são divergentes, oscilando maioritariamente entre o moderado e elevado. Níveis superiores de escolaridade, de capacidade funcional e funcionalidade familiar parecem estar associados ao IVP, variáveis estas que depois de devidamente identificadas devem ser trabalhadas no sentido de assegurar aos idosos um envelhecimento ativo e com qualidade.
La influencia futura de la pandemia desde el plano psicologico en los adolescentes
Authors: Muelas Plaza Álvaro
Published: December 2021

Los primeros meses del año 2020 se recordarán en todo el mundo como uno de los momentos más importantes en la historia del mundo, debido a la aparición del COVID-19, que produjo que en apenas unos días el mundo se paralizara. El 11 de marzo de 2020 la Organización Mundial de la Salud (OMS) tuvo que declarar la COVID-19 como pandemia, haciendo que tres días más tarde, el 14 de marzo de 2020 el Gobierno de España tuviera que aprobar un Real Decreto (RD 463/2020, declarando un Estado de alarma, con el objetivo de proteger de la mejor manera posible a toda la ciudadanía y evitar que la enfermedad se pudiera propagar rápidamente por toda la población. Esta circunstancia ha hecho que desde ese momento la vida de cualquier ciudadano ha cambiado desde todos los ámbitos de su vida, y uno de ellos es de donde este artículo se quiere centrar, como es desde el plano psicológico. Los hechos cotidianos integrados en el día a día de una persona se han visto afectados, y si en cualquier edad es importante, más lo es en etapas evolutivas como la adolescencia, en donde la persona se encuentra en un momento vital donde necesita de una manera notoria su búsqueda de identidad. Se ha visto a través de estudios recientes (Orgiles, et.al, 2020) como la pandemia ha influido en el aumento de estrés y ansiedad en los adolescentes, al igual que en su estado emocional, sintiéndose enfadados, nerviosos, irascibles y tristes (Tiwari et al., 2020). A través de este artículo se pretende dar respuesta a las necesidades psicológicas futuras que van a necesitar los adolescentes en su desarrollo personal.
EVIN, una aplicación adaptativa integral para el entrenamiento visual online de niños con baja visión
Authors: Santos Plaza Carlos Manuel , Matas Martín Yolanda , Hernández Del Olmo Félix , Gaudioso Vázquez Elena
Published: December 2021

La baja visión es una deficiencia visual que no puede ser mejorada con ayudas ópticas convencionales. No obstante, para incrementar sus habilidades estas personas pueden seguir un programa de entrenamiento visual planificado y supervisado por un experto en este campo. Este entrenamiento es especialmente efectivo en niños, debido a su plasticidad para aprender. Pero, debido a la falta de expertos especializados, las sesiones de entrenamiento son generalmente menos frecuentes de lo que sería conveniente. Los programas de entrenamiento visual online son una solución para mitigar este problema, porque pueden ser llevado a efecto por expertos y familias de forma conjunta. De este modo, desarrollamos la aplicación Estimulación Visual en Internet (EVIN), que proporciona un programa de entrenamiento visual en diferentes tareas a través de juegos. Además, presenta informes de los resultados de los niños durante el entrenamiento. Aunque en trabajos anteriores ya se ha probado la utilidad de EVIN, se ha visto necesaria abordar dos nuevas metas: (i) proporcionar algún tipo de soporte en EVIN que ayude a expertos y familias a trabajar juntos debido, entre otras causas, a la gran variedad de ejercicios y configuraciones que pueden ser prescritas a los niños y, (ii) diseñar un riguroso experimento para comparar el entrenamiento visual en niños con EVIN con el entrenamiento con métodos tradicionales. Para afrontar estos objetivos, presentamos una versión adaptativa de EVIN que proporciona una nueva herramienta que permite al experto planificar el entrenamiento visual usando plantillas de ejercicios prediseñadas. Además, hemos desarrollado nuevas métricas e informes que permiten valorar con mayor precisión los resultados de los niños. Todo ello nos ha permitido desarrollar un experimento para evaluar si se produce mejora significativa en los niños entrenados con EVIN.

Zircons in zonal dunite-clinopyroxenite massifs represent a bank of isotopic data on the brightest moments in the life of his generations in the range up to 3 billion years. The chronological coincidence of the set of such dating forms distinct “family” clusters with reference homologous series of “named” impact events in strict galactic periodicity leads us to the unequivocal conclusion that these coincidences are a natural manifestation of galactic periodicity (with a period of 215 Ma) of all endogenous and impact events in the history of the Earth since the origin of the Earth-Moon system 4.515 billion years ago [20, 9]. The zonal dunite-clinopyroxenite massifs turn out to be the richest archives of isotopic information about the age and transformations of the Earth’s substance almost from the moment of its birth in the Hadean in bowels of the Earth.

Authors:   Institute of Geology, Komi Science Center, Ural Branch of the Russian Academy of Sciences, Sukharev A.E.
Published: December 2021

Phase transformations of pyrolytic boron nitride were studied under thermobaric conditions, providing direct transformation of a hexagonal structure into a cubic one. If only the martensitic mechanism of the cooperative rearrangement of atoms is realized, diamond-like aggregates with an equiaxed highly dispersed structure and submicron grain sizes are formed. The presence of a solvent-catalyst (RC) in the system leads to an increase in the particle size of the cubic phase due to recrystallization by the diffusion mechanism, and the high catalytic activity of RC causes the appearance of zones of directional crystal growth in the synthesized samples.

The general geochemical specificity of the Solikamsk Formation is shown, manifested in the titanium minimum and selenium-cadmium-tellurium maximum. Most of the lithophilic, chalcophilic, and siderophilic elements are associated with illite, the content of which first decreases along the section and then increases, which is explained by the transgression and subsequent retreat of the sea. A smaller part is associated isomorphically with carbonate (with dolomite Mo and Pd, with calcite - TR) or sulfate composition (Sr) and associated sulfate reduction (As, Te, Ru, Rh, Hg, Re). It is shown that the rocks of the post-salt deposits are depleted in lithophilic elements, enriched in low-melting noble metals, which, along with the absence of a europium minimum, indicates a substantially basaltoid composition of the petro-fund, which is consistent with the femic specialization of the Ural orogen. It is noted that a gradual “continentalization” of the sediment composition occurs up the section, manifested in an increase in the content of lithophiles, including due to aleuropsammitic material.

In contrast to the carbonate-sulfate evaporites of the Syukeevskoe deposit and the salts of the Starobinskoe deposit, the formation of the salt stratum of the Verkhnekamskoe deposit is assumed to involve melt water formed between the P2 and P3 glacial events. Comparison of host rocks and newly formed mineralization made it possible to show that the process of diagenesis in carbonate-argillaceous strata alternating with rock salt was difficult. Initially, there was a decomposition of dispersed plant detritus, which is confirmed by the lightening of the isotopic composition of carbon. After the interaction of sulfate-containing sediment with desalinated waters, the anhydrite was replaced by 16O-enriched calcite. The complete lithification and stratification of clay strata led to the formation of exfoliation cavities, in which halite-calcite veins of columnar structure were formed associated with the influx of brines from neighboring salt strata enriched in 18O.

The chromitites mineral composition from the Central ore body of the Main Saranovskoye deposit has been studied. Development of chromite grains in silicate interstices; constancy of its composition, idiomorphism; increased chromium content of small and periphery of large chromite grains; absence of corrosion, substitution with chrome magnetite or chlorite; xenomorphic high chromium chromite; association with chromium-containing minerals and minerals of hydrothermal origin; joint growth of chromite with uvarovite; predominance of minerals with Na and H2O in inclusions in chromite; inclusions of idiomorphic grains and chlorite laths, massicot crystals; the inclusion of laurite with a crystallographically faceted inclusion of chalcocite, chromite in the diabase skarn indicates that chromite was not a source of chromium for other minerals, but was formed together with hydrothermal minerals in the course of a single process. This is also evidenced by the composition of apatite: a high Y content and a negative Eu anomaly.
Revisiting the Zimbabwean Unfair Labour Practice Concept
Authors: Kasuso Tapiwa Givemore
Published: December 2021

The 2013 Constitution of Zimbabwe entrenches the broad right to fair labour practices. The right is given effect to in Part III of the Labour Act (Chapter 28:01), which provides an exhaustive list of unfair labour practices which can be committed by employers, trade unions, workers' committees, and other persons. The Labour Act predates the 2013 Constitution. The constitutionalisation of the right to fair labour practices necessarily carries with it the attendant difficulties of reconciling the new rights and the pre-existing regulatory framework. This article seeks to contribute towards a practical understanding of the Zimbabwean unfair labour practice concept in the light of the constitutionalisation of the right to fair labour practices. It explores the nature and scope of the concept of unfair labour practice and examines its relationship with the constitutional right. Further, the contribution critiques the formalistic and conservative approach adopted by the Constitutional Court in explaining this relationship. The article commences with a brief discussion of the origins of the concept and its reception in Zimbabwean labour law. Following from this, the contribution critically analyses the unfair labour practice concept from statutory and constitutional perspectives. It argues for an expanded paradigm of the concept. This can be achieved if the judiciary moves away from pedantic approaches to the interpretation of labour rights. Therefore, the clarion call is for a purposive and expansive interpretation of the right to fair labour practices, which promotes constitutionalism. In addition, the contribution calls upon the legislature to reconsider the viability of the exhaustive list of unfair labour practices in Part III of the Labour Act, given the constitutionalisation of the broad right to fair labour practices.
Classification and characterisation of smallholder farmers in South Africa: a brief review

Published: December 2021

The South African agricultural sector has experienced various transformation processes over the past 25 years, from a predominantly white commercial sector to a black focused sector with an emphasis on smallholder farming. The government is committed to supporting the smallholder farming sector through interventions that include land reform and access to water, amongst others. Despite these efforts, smallholder farmers remain vulnerable, especially during drought periods. Smallholder farmers are not homogeneous; instead, they are diverse, and their farming needs also differ according to their livelihood needs. Due to the diversity of smallholder farmers, it is difficult for the government to effectively respond to their needs. The 2015–2018 drought is a case in point. This paper assesses the challenges of defining and classifying smallholder farmers in South Africa. The complex Western Cape classification system is presented as a case study. The study concludes that there is a need for a simpler method of grouping the smallholder farmers based on their livelihoods to develop relevant support systems.

Introduction. Friction stir welding and processing are almost identical processes of severe plastic deformation at elevated temperatures. These technologies differ mainly in the purpose of its use: the formation of a hardened surface layer or producing a welded joint. However, it is known that both during welding and during processing of heavy gauge workpieces temperature gradients occur. As a result, the conditions of adhesive interaction, material plastic flow, and the formation of the stir zone change as compared to thin-sheet workpieces with fundamentally different heat dissipation rates. In this connection, the purpose of the work is to determine the regularities of the structure formation and stability of the mechanical properties in different directions in the material of 35-mm-thick aluminum-magnesium alloy samples produced by friction stir welding/processing. Research Methodology. The technique and modes of friction stir welding and processing of AA5056 alloy workpieces with a thickness of 35 mm are described. Data on the equipment used for mechanical tests and structural research are given. Results and discussion. The data obtained show the excess mechanical properties of the processing zone material over the base metal ones in all studied directions. Material structure heterogeneities after friction stir welding/processing of heavy gauge workpieces have no determining effect on the stir zone properties. At the same time, there is no clear correlation between the tensile strength values and the load application direction, nor is there any significant difference in mechanical properties depending on the location of the samples inside the stir zone. The average ultimate tensile strength values in the vertical, transverse, and longitudinal directions are 302, 295 and 303 MPa, respectively, with the yield strength values of 155, 153 and 152 MPa, and the relative elongation of 27.2, 27.5, 28.7 %.
