Authors: Nugroho Naufal Adi , Sulistiyani Sulistiyani , Dewanti Nikie Astorina Yunita
Published: January 2022

COD level of Pojok Laundry’s wastewater did not meet the quality standard regulated in the Special Region of Yogyakarta Regulation No. 7 of 2016 (>150 mg/l) which was 442.5mg/l. This study was aimed to decrease COD levels using the tray aerator method. Manganese greensand with a diameter of 0.25 mm and a thickness of 2.4 cm/tray was also added. This type of research was a quasi-experimental with Nonequivalent Control Group Design. The sample in this study amounted to 50 samples with 5 treatments (30, 45, 60, 75, and 90 minutes), and 5 repetitions. Samples were taken from the washing machine outlet pipe. There were two groups, where the control group was only given aeration and the treatment group was given aeration with the addition of manganese greensand. Data analysis using the two-way ANOVA test showed that there was an effect of time variations on the decrease in COD levels (p<0.05), there was a difference in the average of decreased levels of COD between the control and treatment groups (p<0.05). The average decrease in COD levels after treatment with a time of 30, 45, 60, 75, and 90 minutes, respectively, was 195.7 mg/l (28.80%); 299.0 mg/l (43.63%); 372.1 mg/l (54.79%); 438.3 mg/l (64.61%); and 513.8 mg/l (75.45%). The decrease in COD levels increased with time. The conclusion of this research was that tray aerator with manganese greensand addition can reduce COD levels with the highest reduction up to 76.69% (90 minutes treatment, detergent usage: 30 g).

Published: January 2022

Crude oil contamination is considered highly toxic and poses a significant environmental problem. As an alternative, the laccase enzyme showed high performance for removing various toxic contaminants, particularly oil-contaminated soil (i.e., total petroleum hydrocarbon). However, previous studies mainly tested the performance of laccase under irrelevant environmental conditions (i.e., artificially contaminated soil) with a limited number of soil samples, which can lead to bias optimization results for assessing laccase performance. Two types of natural oil-contaminated soils were tested under various reaction times and various concentrations of laccase extracted from Marasmiellus palmovorus. In addition, response surface methodology was used to find the maximum degradation of total petroleum hydrocarbon (TPH). The maximum degradation of TPH from soil A and soil B were 48.57% and 54.1%, respectively. Moreover, the performance of the laccase enzyme for oil recovery was also tested, with the percentage of oil recovery being 9.89% and 10.1 % for soil A and soil B, respectively. SARA fraction analysis indicated that laccase enzyme preferentially degraded highly polar SARA fraction (i.e., asphaltene and resin). In general, the application of laccase for the enzymatic remediation of oil-contaminated soils was practical. Hence, the use of laccase for environmental application is still promising.

Authors: Muhyidin Muhyidin , Nasri Sjahrul Meizar
Published: January 2022

The purpose of this study will analyze noise intensity at a geothermal power plant and its association with employees’ blood pressure and risk of hypertension. A cross-sectional survey using questionnaire as primary data; noise dosimeter, body mass index and blood pressure measurement records as secondary data. Total 101 workers participated by purposive sampling based on a similar exposure group (SEG). Mann-Whitney & χ2 test analysis was applied to examine the association of dependent variables and independent variables. Noise intensity was measured from the noise dose result during 8 working hours. Subjects with noise dose >80 dBA had higher levels of SBP / systolic blood pressure (119.1±11.2 mmHg) and DBP / diastolic blood pressure (75.6±5.3) than subjects with noise dose ≤80 dBA (SBP: 117.9±6.6 mmHg, DBP: 75.0±5.1). The hypertension prevalence was 7.9% at participants with noise dose >80 dBA and 2.6% in noise dose ≤80 dBA. The odds ratio (OR) of noise dose >80 dBA (OR = 3.190, 95% CI = 0.358-28.394), and smoking (OR = 2.469, 95% CI = 0.416-14.645). Noise intensity was not associated with SBP (p-value = 0.664), DBP (p-value = 0.538), and hypertension (p-value = 0.405). This study was the pioneer in the geothermal industry with noise dosimetry measurement. Further comprehensive studies need to be conducted to confirm the association between noise intensity and blood pressure and the risk of hypertension.
Autoritäre Akkumulation
Authors: Redecker Eva von
Published: January 2022

In The Origins of Totalitarianism Hannah Arendt reads Hobbes’ Leviathan as a prefiguration of totalitarian politics. She does so in a unique manner, criticising not his overbearing sovereignty, but the incessant accumulation of power, which turns into an unstoppable process of destruction. Arendt claims that the ultimately self-annihilating accumulation of power is necessitated by bourgeois societies’ pursuit to increase property. This paper first clarifies the methodological assumptions which allow Arendt to read Hobbes’ theory as a clue to bourgeois history in general. It then reconstructs her portrait of the “power-hungry individual” as a result rather than starting point of Hobbes’ political model, and examines her verdict that the Hobbesian sovereign is inherently unstable. With the help of passages contained only in the expanded German version of Origins, Arendt’s more familiar Luxemburgian critique of territorial expansiveness is completed by a Benjaminian analysis of the temporality of accumulation: colonial catastrophe.

Natur zwischen Übermacht, Unschuld und Instrument
Authors: Grivaux Agnès
Published: January 2022

This article emphasises the relevance of Adorno’s concept of nature for contemporary debates in critical theory about the relationship between nature and society. Adorno identifies a twofold danger for a critical understanding of our relationship to nature. While the first is in the development of a mythical vision of nature, the second is in the development of a purely instrumental relationship to nature, which considers nature as an entity radically heterogeneous to social issues. Against this backdrop, Adorno develops his own concept of nature which can be described as negative (non-mythical) and minimal (non-instrumental).
Die gesellschaftliche Destabilisierung der Natur und die Rückkehr des Naturschreckens
Authors: Hogh Philip
Published: January 2022

This article demonstrates the ways in which Adorno’s and Horkheimer’s reflections on the dialectic of the domination of nature shed new light on recent discussions about the concept of the Anthropocene. A central motif is the fear of nature, which, according to Adorno, prevailed at the beginning of its mastery by humans in prehistoric times. Harnessing external nature enabled the stabilisation of internal nature and social relations. This link between nature’s relative stability and social relations was characteristic of the Holocene. In the Anthropocene, capitalist domination destabilises nature, which in turn destabilises social life. Thenaturalterror of nature returns in the face of the socially produced climate catastrophe, adding a new aspect to Adorno’s and Horkheimer’s diagnosis of the domination of nature. The article concludes by suggesting a changed relationship to nature, which no longer would understand it as a mere object, but as a “subject in its own right”.
Fruits consumed by phyllostomid bats in a Peruvian Yungas forest: new dietary items for Chiroderma salvini and Lonchophylla handleyi
Authors: Pellón Juan J.
Published: January 2022

Through an analysis of seeds in faeces, I recorded some fruits consumed by 13 bat species in a premontane forest of the buffer zone of Santuario Nacional Pampa Hermosa (Junin, central Peru) in March 2017. Platyrrhinus albericoi was found for the first time in the area. Results provide the first evidence of granivory by Chiroderma salvini and frugivory by Lonchophylla handleyi, and additional records of fruits consumed by some Neotropical frugivorous bats in premontane forests.

We develop in this paper a Susceptible Exposed Infectious Hospitalized and Recovered (SEIHR), spread model. In the model studied, we introduce a recruitment constant, to take into account the fact that newborns can transmit disease. The disease-free and endemic equilibrium points are computed and analyzed. The basic reproduction number 𝒭0is acquired, when 𝒭0≤ 1, the disease dies out and persists in the community whenever 𝒭0> 1. From numerical simulation, we illustrate our theoretical analysis.
On the CaF2-BaF2 interface
Authors: Merkle Rotraut , Maier Joachim
Published: January 2022

Ionic redistribution at solid interfaces in ionic materials is the keystone of nanoionics. An experimental master piece has been provided by CaF2-BaF2 heterolayers. Meanwhile this system and the involved heterojunctions are extraordinarily well-understood. The present paper gives an account of this model system by reviewing not only transport experiments and defect-chemical modeling as a function of temperature and spacing of the individual layers, but also transition from semi-infinite to mesoscopic conditions, transition from Mott–Schottky to Gouy–Chapman behavior as well as the impact of ionic redistribution on the electronic minority carriers. Owing to the availability of bulk transport data, the analysis works well for in-plane and out-of-plane measurements with only the space charge potential as fit parameter. Space charge effects are able to provide an interpretation of the annealing behavior, too. The experiments are corroborated by molecular dynamics simulations. Extrapolating the ionic redistribution effects down to the atomic level may even explain homovalent doping effects in non-equilibrium mixtures of the two fluorides.
Working-class Commuters and Innovative Use of Associational Power: The Case of Mamelodi Train Sector in South Africa
Authors: Mmadi Mpho
Published: January 2022

The article analyses the power resources of working-class train commuters in Tshwane, South Africa. I examine the organisational strategy of Mamelodi Train Sector (MTS), considering the crisis of representation characteristic of the South African labour movement currently. With changing composition of membership in the Congress of South African Trade Unions, the article begins with the question, what strategies and avenues are there for both unions and unorganised members of the working class? Through the case study of MTS, I suggest a need to rethink power resources and strategies in order to appreciate various non-union ways in which workers continue to organise under conditions that are at times hostile to unions. Drawing on the Power Resources Approach, I argue that MTS can utilise its strategic site of operations and associational power to link unorganised workers with relevant unions. Through its on-train organising, MTS strategically uses its associational power to achieve two things: 1) to empower non-unionised workers, and 2) to influence local-level politics during the morning and afternoon commutes.

Precarious Workers and the Labour Process: Problematising the Core/Non-core
Authors: Dor Lynford , Runciman Carin
Published: January 2022

This article recentres labour process theory in the analysis of the South African manufacturing sector to challenge the perception that precarious workers in the formal economy are largely “flexible extras” unrelated to the “core” of production. Through case study analysis of two manufacturing workplaces in Gauteng, South Africa, we demonstrate how precarious workers are both core to production and to the production of surplus value. Our analysis demonstrates how employers have increasingly restructured work through reclassifying large parts of the labour process as “non-core”. This trend has accelerated in recent years as employers seek to evade new legal responsibilities following amendments to the Labour Relations Act in 2014. Despite employers’ attempts to redefine the labour of precarious workers as non-core, we demonstrate that these workers nevertheless play an increasingly central role in the valorisation regimes of manufacturing companies – rendering them core to the production of surplus value for manufacturing capital. Our analysis problematises Von Holdt and Webster’s (2005) core/non-core schema for analysing the South African labour force, which locates precarious workers in the formal sector in the non-core. We argue that while this schema has some utility in describing the make-up of the labour force, its abstraction from an analysis of the labour process obscures the fact that precarious work has become central to manufacturing capital’s valorisation strategy. Finally, the article reflects on how precarious workers are attempting to organise within and in parallel to trade unions. This analysis highlights the importance of going beyond analysing trade unions if we are to contribute to rebuilding the labour movement under conditions of precarity.

Dusun Nipah Kabupaten Lombok Utara terkenal dengan objek wisata nya yang berupa pantai yang mana sangat menarik untuk dikunjungi. Warga sekitar banyak yang menjajakan dagangannya disekitar lokasi objek wisata. Tidak sedikit warga sekitar di Desa Malaka khususnya Dusun Nipah membuka lapak di sekitar objek wisata pantai maupun di pinggir jalan untuk berjualan kelapa, ikan bakar, dan jagung bakar. Selain itu di Dusun Nipah juga terdapat tempat pengolahan produk berbasis kelapa yang Bernama UKM Bukit Kelapa. UKM tersebut memproduksi santan kelapa dan minyak kelapa. Dalam prosesnya pegawai UKM Bukit Kelapa menggunakan alat sederhana dalam melakukan pengupasan dan pembelahan kelapa, yaitu berupa linggis. Pengupasan dengan cara ini terbilang masih jauh dari tingkat efisiensi yang  diinginkan, karena  membutuhkan waktu yang lama, tenaga yang besar, dan sangat beresiko terjadinya kecelakaan kerja saat pengupasan. Bagian sisi pemotong dari linggis yang tajam sejajar dengan tinggi perut pengguna sehingga sangat rentan melukai perut jika tidak dilakukan dengan hati-hati. Melihat kondisi tersebut maka diperlukan pengenalan teknologi berupa alat pengupas kelapa yang lebih efektif dan aman digunakan. Melalui kegiatan pengabdian ini, diharapkan dapat membantu kelompok UKM dusun Nipah, Desa Malaka, Kabupaten Lombok Utara dalam pengupasan kelapa sehingga dapat menghemat waktu, tenaga, tingkat keamanan yang lebih tinggi, dan mampu meningkatkan kapasitas produksi.

Community service activities aim to identify the completeness of the institutional elements of BUMDes Sumber Arto Kenteng Village. The service method used is the socialization of BUMDes strengthening following government regulation number 11 of 2021 and the procedures, requirements, and registration of BUMDes names. The target of the activity is the BUMDes management and the village secretary. Activities are carried out virtually using zoom meetings, and the continuation of activities is carried out through communication using Whatsapp. The service results showed that participants began to understand the mechanism for proposing BUMDes to legal entities as the main element in strengthening BUMDes institutions. BUMDes already has an organizational structure but does not yet have standard operating procedures for business implementation. These include strategies for team member payroll, cash receipts, cash disbursements, sales, and purchases. Team member turnover is also relatively high, making it challenging to perform the functions of the supervisory and accounting departments. Therefore, it is necessary to create and set standard operating procedures. These operational standards are legalized in village consultation meetings (musrenbangdes).

Published: January 2022

This study investigated whether norepinephrine (NE) and epinephrine (E) interfere in the response of head and neck squamous cell carcinoma (SCC) cell lines to cisplatin and explored the mechanisms of chemoresistance. Head and neck SCC-derived cell lines SCC-9, Cal27, SCC-25, and FaDu were stimulated with NE or E and treated with the inhibitory concentration of cisplatin for 24 h. As for adrenergic receptors (ADRB) inhibition, cells were treated with propranolol. The results showed that, when combined with NE, cisplatin effectiveness against SCC-9 and Cal27 but not SCC-25 and FaDu cells were notably reduced. E did not affect the response of the cells to cisplatin. Further experiments were performed with the responsive SCC-9 and SCC-25 cell lines and the hormone NE. The time course assay showed that stimulation of oral SCC cells with NE decreased the cleavage of caspase-3 and expression of multidrug resistance protein 1 (MDR-1) but only transiently affected ATP-binding cassette (ABC) subfamily G, isoform 2 protein (ABCG2) expression. The expression of cleaved caspase-3 and Bcl-2 were, respectively, decreased and increased by the combination of NE and cisplatin in SCC-9 and Cal27 cells. NE-induced resistance was reverted by previous treatment with propranolol. Expressions of ABCG2, and p-Akt but not of MDR-1, were enhanced by NE plus cisplatin when compared to cisplatin only in both cell lines. Migratory activity of oral SCC cells challenged with cisplatin was not affected by NE. These findings reveal for the first time that stress hormone NE induces resistance of oral cancer cells to cisplatin in vitro through the ADRB/Akt/ABCG2 pathway, pumping the drug out of the cell and inhibiting apoptosis.
Can a Digital Therapy Using Sound and Light Reset the Balance of Alzheimer’s Disease?
Authors: Wood Julia N. , Will Carson
Published: January 2022

Alzheimer’s disease (AD) is a degenerative cognition-declining disease with no clear understanding of the underlying mechanisms. Currently, no effective therapeutics are available for AD. Amyloid-β (A-β) plaques and tau tangles were considered as the contributing factors to the development of AD. In contrast, controversial exists due to efforts focusing on A-β as a pharmacological therapeutic target was failed. Emerging evidence appeared for the external stimuli applied through vision (LED) and hearing (~40Hz) to certain intensity to dementia subjects with promising results such as reducing A-β and tau tangles in the brain tissue, increasing the brain volume reducing the decline of daily activities and mental status. This optogenetic and sound-derived digital therapeutic maneuver provides a striking way for conquering the development of AD.

Published: January 2022

Background: Rheumatoid arthritis (RA) is an autoimmune inflammatory disease with complex etiopathogenesis launched by multiple risk factors, including epigenetic alterations. RA is possibly linked to vitamin D that is epigenetically active and may alter DNA methylation of certain genes. Therefore, the study aimed to evaluate the relationship between DNA methylation status of vitamin D signaling pathway genes (VDR, CYP24A1, CYP2R1), vitamin D level and associations with RA.Materials and Methods: Totally 76 participants (35 RA patients and 41 healthy controls) were enrolled from a case-control vitamin D and VDR gene polymorphisms study regarding age and vitamin D concentration. CpG islands in promoter regions of the VDR, CYP24A1, CYP2R1 genes were chosen for DNA methylation analysis by means of pyrosequencing. Chemiluminescent microplate immunoassay was used to assess 25(OH)D serum levels. RA clinical data, i.e. the disease activity score C-reactive protein 28 (DAS28 – CRP) as well as patient-reported outcome questionnaires were recorded.Results: The study showed similar methylation pattern in the promoter regions of vitamin D pathway genes in RA and control group with p>0.05 (VDR gene 2.39% vs. 2.48%, CYP24A1 gene 16.02% vs. 15.17% and CYP2R1 2.53% vs. 2.41%). CYP24A1 methylation intensity was significantly higher in compare to methylation intensity of VDR and CYP2R1 genes in both groups (p<0.0001). A tendency of higher vitamin D concentration in cases having methylated VDR (57.57±28.93 vs. 47.40±29.88 nmol/l), CYP24A1 (53.23±26.22 vs. 48.23±34.41 nmol/l) and CYP2R1 (60.41±30.73 vs. 44.54±27.63 nmol/l) genes and a positive correlation between VDR, CYP2R1 methylation intensity and vitamin D level in RA affected participants was revealed (p>0.05). A significantly higher CYP24A1 methylation intensity (p=0.0104) was detected in blood cells of vitamin D deficient (<50 nmol/l) RA patients vs. vitamin D deficient controls.Conclusions: Our data suggests some indirect associations between DNA methylation status of vitamin D pathway genes and vitamin D level in RA.
Nature of Hydrogen Bond in Water

Published: January 2022

The work is devoted to the investigation of the physical nature of H-bonds. The H-bond potential ΦH (r, Ω ) is studied as an irreducible part of the interaction energy of water molecules. It is defined as a difference between the generalized Stillinger–David potential and the sum of dispersive and multipole interactionpotentials. The relative contribution of ΦH (r, Ω ) to the intermolecular potential does not exceed (10–15)%.
Convolution Problems in Time-Resolved X-Ray Diffraction
Authors: Bratos S. , Leicknam J.-Cl.
Published: January 2022

Convolution problems in the time-resolved scattering of 10–1000-ps x-ray pulses are studied theoretically. The model system is a diluted solution of diatomic molecules A2 dissolved in an inert solvent. This system is submitted to a sub-picosecond laser pulse, which promotes the molecules A2 into an excited electronic state. The molecule then return into their ground state, passing through several intermediate electronic states. The effects of the finite duration of probing x-ray pulses on various x-ray signals are then examined in the frame of this model. Unbiased signals generated by very short x-ray pulses are explored first. Variations of a molecular geometry during this process are clearly visible in r-resolved, but are less explicit in q-resolved signals. The signals measured with x-ray pulses of a finite duration are studied next. Atomic motions remain detectable, but only if the x-ray pulses are shorter than or comparable to the times of a molecular dynamics. Here again, the r-resolved signals are more appropriate for monitoring the molecular dynamics than q-resolved signals. Finally, the effect of the insufficient temporal location of probing x-ray pulses with respect to that of exciting laser pulses is examined. It is shown that this last effect can be accounted for by simply replacing the true x-ray pulse intensity by another theoretically predicted intensity. The similarity of deconvolution techniques in spectroscopy and in time-resolved x-ray diffraction is strongly emphasized.

Ab initio calculations of the electronic structures are carried out for the novel FeSe1–xTex superconductors to explain the experimentally found anomalous magnetic properties in the normal state. The calculations have shown that FeSe1–xTex systems are close to a magnetic instability with dominating enhanced spin paramagnetism. The magnetic susceptibility is found to increase gradually with the Te content. The temperature dependences of the magnetic susceptibility χ and its anisotropy ∆ χ = χ║ – χ┴ are investigated for FeSe, and a growth of the susceptibility with the temperature is revealed in the temperature range 4.2–300 K. For FeTe, a substantial increase of χ under pressure is found. The calculated paramagnetic susceptibility exhibits a strong dependence on the unit cell volume V and especially the height of chalcogen species from the Fe plane. The calculations have explained the experimental data on χ(T) and χ(P) for FeSe and FeTe, respectively.

The nonlinear-optical response of anisotropic smectic glasses based on cobalt-alkanoates is studied using the method of dynamic holography. Laser-induced dynamic gratings under the action of nanosecond laser pulses are observed and analyzed for such materials. It is found that a cubic optical nonlinearity of all studied anisotropic glasses is of electronic origin in the nanosecond diapason and caused by a nonlinear polarization of cobalt-alkanoates complexes.
The Spectral Properties and Photostability of DNA, RNA, and Oligonucleotides
Authors: Kudrya V.Yu. , Yashchuk V.M.
Published: January 2022

The present work discusses the results of comparative investigations of the optical absorption, luminescence, and photostability of the biomacromolecules (DNA, RNA), as well as synthetic poly- and oligonucleotides. The separate nucleotides in DNA and RNA are examined as almost independent absorbing centers. It is confirmed that the main triplet excitons traps responsible for the DNA phosphorescence emission are AT-complexes in DNA. In contrast toDNA, the main triplet excitons traps in RNA are adenosine bases. These bases are the most photostable against UV-irradiation as compared with all other nucleotides in both DNA and RNA. The fact of the photostability of adenosine bases and the AT-complex provides the existence of the DNA/RNA self-protection mechanisms against a damage caused by UV-irradiation. It is found the deoxyribonucleotides are more photostable than the correspondingribonucleotides. So, the results presented here show that DNA is more photostable than RNA.
Degradation of Chlorophyll Luminescence in Plants

Published: January 2022

The chlorophyll photoluminescence intensity degradation of Vallisneria spiralis L. water plant is studied. It is shown that the degradation curve is rather well described by a sum of two hyperbolic functions. The rate of intensity degradation reduces at low temperatures. At room temperature, a slow restoration of the luminescent system is observed after the irradiation has been ceased. No restoration is detected at the liquid nitrogen temperature. A simplified model which describes the luminescence degradation according to the quadratic law is suggested.
Entre Plínio Salgado e Miguel Reale
Authors: Pacheco Gabriela Santi
Published: January 2022

O corporativismo foi um dos mais influentes modelos autoritários de representação da primeira metade do século XX, desenvolvendo-se tanto na Europa como em outras partes do mundo, como é o caso do Brasil, onde diversos intelectuais elaboraram teorias permeadas pela ideia do Estado corporativo enquanto forma de organização política e social. Destacam-se, dentre outros, Plínio Salgado e Miguel Reale, líderes da Ação Integralista Brasileira (AIB) – movimento de inspiração fascista criado em 1932, que se baseava em preceitos nacionalistas, antiliberais e anticomunistas e tinha como objetivo central instaurar o “Estado Integral”, pautado pelo teor nacional-corporativo. Partindo da análise histórica comparativa, cujo traço distintivo é a investigação de trajetórias singulares a fim de compreender fenômenos da história mundial, tem-se o objetivo de analisar como as trajetórias individuais de Salgado e Reale influenciaram na formulação de suas teorias acerca do corporativismo, haja vista que, apesar de partilharem ideias em relação a diversos aspectos doutrinários acerca do movimento integralista, existem particularidades e divergências na elaboração do pensamento de cada um desses intelectuais.

No ano de 2021 foi realizada a presente entrevista com a professora Dra. Melina Perussatto. A entrevista versa sobre o mundo do trabalho, focando nas áreas de especialidade da entrevistada, tais como emancipações e pós-abolição no Brasil, bem como sobre temas da atualidade. A preocupação para a realização da presente entrevista se deu pela necessidade de discutir temas atuais os relacionando com a historiografia, e a necessidade de trazer sempre à tona a questão do mundo do trabalho no Brasil: tema que está sempre muito presente no dia a dia de todos os cidadãos e de constantes debates e múltiplos vieses teórico-metodológicos. Na entrevista, a professora Melina traz suas considerações sobre o tema, e aponta sua própria trajetória acadêmica como um ponto de partida da discussão. Seus aportes de teoria e metodologia são explicados no texto, e suas fontes de pesquisa são abordados para mais lucidações da questão. Através de questões teóricas e de referências acadêmicas, Melina Perussato nos fornece material para reflexão. Uma aula em forma de entrevista é o que aqui é apresentado, nos levando por caminhos da historiografia recente sobre o mundo do trabalho através de um ponto de vista crítico.
Virtudes y debilidades en la mirada del Capital Humano en las Instituciones de Educación Superior
Authors: Maluenda Albornoz Jorge
Published: January 2022

El presente ensayo analiza el Enfoque del Capital Humano en la educación superior contraponiendo argumentos que defienden su valor y advierten de sus problemas. El objetivo que persigue es analizar las virtudes y debilidades más relevantes del Enfoque del Capital Humano en el contexto de la educación superior latinoamericana. El análisis muestra cómo es posible observar grandes contribuciones de este enfoque en cuanto a la gestión estratégica y eficiente de la enseñanza y administración de la educación superior, la valorización de los intangibles y la consideración del entorno. También, muestra como principales problemas una tendencia a la reducción de los propósitos humanos, el utilitarismo y el alineamiento potencial de los estudiantes y futuros profesionales. Se concluye la existencia de contribuciones relevantes de este enfoque a la gestión educativa, especialmente necesarios, considerando la escasez de recursos y el ingreso masivo de los estudiantes durante los últimos 30 años en Latinoamérica. Estos pueden ser aprovechados de mejor manera cuando no se pierden de vista los propósitos originales y más importantes de la educación superior.
Una aproximación a la noción relación con el saber, revisada a la luz de la teoría del sujeto de Lacan, para aplicar en la investigación de los procesos productivos de arte visual en estudiantes universitarios
Authors: Pastorino Magalí
Published: January 2022

La noción relación con el saber tiene vigencia en el campo de la investigación en educación e introduce, dada su densidad conceptual, la cuestión del sujeto y el saber.

En la vía de Beillerot, dicha noción entraña un proceso creador singular, pertinente para la enseñanza artística universitaria en arte visual, por lo que, profundizar en ella, actualiza el campo de estudios de los procesos productivos.

No obstante, su origen radica en un sintagma de la obra lacaniana de los años sesenta. A la luz de dicha obra, nos proponemos revisar los alcances de la relación con el saber para aplicar en la investigación de los procesos productivos de estudiantes avanzados universitarios de arte visual.

De esta manera, integramos las formaciones inconscientes al campo de la enseñanza artística universitaria en arte visual.
„Jobb politikák a jobb életért”.
Authors: Polónyi István
Published: January 2022

Összefoglaló. Az OECD 1961-ben – hatvan éve – alakult, s
Magyarország 1996 óta, 25 éve tagja a szervezetnek. Ez a kettős évforduló
teremtett arra alkalmat, hogy az Educatio egy tematikus szám
keretében elemezze a szervezet céljait és jelentőségét, meghatározóan az
oktatáspolitikai hatását, de kitekintve a gazdaságpolitikai összefüggésekre is.
Az írás először felvillant néhány véleményt az OECD-ről, elsősorban annak
oktatáspolitikai szerepéről, majd bemutatja az OECD 1961/2021 című
Educatio szám szerzőit és az írások legfontosabb
mondanivalóját.

Summary. The OECD was founded in 1961 – sixty years ago – and
Hungary has been a member since 1996, 25 years ago. This double anniversary
provided the opportunity for Educatio to analyse the aims and
significance of the organisation, its impact on education policy in particular,
but also its economic policy context in a thematic issue. The paper first
outlines some views on the OECD, especially its role in education policy, and
then introduces the authors of the Educatio issue 1961/2021 and
the main messages of the papers.
Az OECD a magyar gazdaságpolitika alakításában: tanácsadó, támogató vagy korlátozó szerep?
Authors: Bod Péter Ákos
Published: January 2022

Összefoglaló. Az OECD rendszeresen értékeli a tagországok gazdasági
helyzetét és gazdaságpolitikáját, munkacsoportjaiban döntéselőkészítő és -elemző
munkát végez. Fő kérdésünk: A munkakapcsolatok és a politikai szintű
konzultációk milyen mértékben és módon hatottak a magyar kormányzati működésre,
gazdaságpolitikai gyakorlatra? Az OECD a mandátuma és tagságának összetétele
folytán nem integrációs szervezet, eltérően az EU-tól, hitelforrásokkal sem
rendelkezik, mint a Világbank és az IMF, tanácsadóként azonban jelentős,
különösen az EU-tagságunk előtti időszakban. Az együttműködés jellemzői sokat
változtak, részben az OECD szerepfelfogásának módosulásai, főként a változó
magyar viszonyok és módosuló kormányzati törekvések nyomán. Az OECD újabban
mindinkább globális érdekegyeztető, normaalkotó és szabályozó jelleget ölt;
ilyen feladatköreiben gyakran ütközik a 2010 utáni magyar szuverenitáselvű
politikai felfogással és nem szokványos gazdaságpolitikai gyakorlattal.

Summary. The OECD periodically surveys the economy and economic
policy of its members, provides decision support and analysis. The main issue
addressed here: in what ways and to what extent has the practice of professional
collaboration and high-level policy dialogues influenced the Hungarian
government and its economic policymaking practice. The OECD, given its mandate
and its membership, is not, unlike the EU, an integration organization, and it
does not allocate funds, unlike the World Bank and IMF, yet as policy advisor it
has been influential, particularly in the years before EU accession. The profile
of the collaboration between successive Hungarian governments and the OECD has
changed a lot, due to shifts in the mandate of the OECD, but mostly because of
changes in Hungary’s situation and government policy lines. The OECD has
increasingly assumed global interest harmonization, norm-setting and regulatory
roles; as a result, tensions have become common due to the Hungarian
government’s pro-sovereignty stand and non-conventional economic policy measures
since 2010.
Az OECD globális politikájának előnyei és hátrányai
Authors: Pogátsa Zoltán
Published: January 2022

Összefoglaló. A tanulmány célja annak vizsgálata, hogy az elmúlt
évtizedekben az OECD milyen szerepet vitt a globális és a nemzeti szintű
szocioökonómiai modellek alakításában. Vizsgáljuk befolyásának erejét, illetve
azt is természetesen, hogy milyen irányba mozdította a folyamatokat. Ehhez
egyrészt visszamegyünk időben a kezdetekhez és elemezzük a szervezet szerepének
alakulását, másrészt pedig összehasonlítjuk más meghatározó nemzetközi
szervezetekkel.

Summary. This study aims to examine the global role played by the
OECD as an organisation in influencing socio-economic models around the world,
as well as in individual nation states, with special attention to the concept of
the ‘knowledge economy’. In order to carry out this assessment, we return to the
precursors of this organisation after the World War Two. The role played by the
OECD is then discussed across time, and in comparison to other major
international economic institutions, such as the IMF, the World Bank and the
European Union.
