Economisch niet-actieve EU-burgers en de zorgverzekeringseis onder de Burgerschapsrichtlijn
Richtlijn 2004/38/EG legt de voorwaarden vast waaronder EU-burgers van hun vrij verkeer gebruik kunnen maken in de EU. Voor economisch niet-actieve EU-burgers zijn bijvoorbeeld specifieke voorwaarden verbonden aan hun verblijf. In het bijzonder gaat het om het hebben van voldoende bestaansmiddelen alsmede het hebben van een dekkende zorgverzekering. Waar het Hof van Justitie in de afgelopen jaren enkele belangrijke uitspraken heeft gedaan over de bestaansmiddeleneis, doet het in de zaak A uitspraak over de zorgverzekeringseis. Deze bijdrage analyseert het nieuwste arrest van het Hof van Justitie in het licht van het geldende Europese recht en rechtspraak.HvJ 15 juli 2021, zaak C-535/19, ECLI:EU:2021:595 (A/Latvijas Republikas Veselības ministrija).

Coördinatie van sociale zekerheid en ‘forumshopping’
De centrale vraag in de in deze bijdrage te bespreken arresten is of, en zo ja, onder welke voorwaarden, ondernemingen gebruik kunnen maken van hun recht op verkeer om profijt te trekken uit verschillen in de socialezekerheidsbijdragen die zij voor hun werknemers moeten betalen. De arresten laten zien dat het Hof van Justitie bijzonder huiverig is voor ‘forumshopping’. De in artikel 12 en 13 Verordening (EG) nr. 883/2004 inzake de coördinatie van sociale zekerheid opgenomen aanwijsregels dienen strikt en op een ‘werknemersvriendelijke’ wijze te worden uitgelegd.HvJ 3 juni 2021, zaak C-784/19, ECLI:EU:C:2021:427 (Team Power), HvJ 20 mei 2021, zaak C-879/19, ECLI:EU:C:2021:409 (Format II), HvJ 16 juli 2020, zaak C-6101/18, ECLI:EU:C:2020:565 (AFMB).

Into the Hottest Century and into Epochal Change
Authors: Therborn Göran 
Published: October 2021

El siglo XXI será el siglo más caluroso en miles de años, y el paisaje social del mundo es volcánico. La política global y las relaciones sociales estarán dominadas por dos temas:la crisis climática y la rivalidad entre Estados Unidos y China.Este artículo analiza los efectos dela «pandemia de desigualdad»de Covid-19; efectos que han debilitadoalgunas fuerzas y han fortalecidootras. También profundizaenlos contextos y perspecti-vas de la crisis climática y en el conflicto entre las dos superpotencias.Lasrespuestasgubernamentalesa la pandemia pusieron fin al régimen global del neoliberalismo y la globalización de mercado sin fisuras, acontecimientossucedidos por el conflicto geopolítico y la movilización interna de las grandes potencias.Es probable que las pro-fundas transformaciones tecnológicas y sociales necesarias para hacer frente a la crisis climática sigan en manos de la política,como de costumbre, con resultados confusospero difícilmente apocalípticos.El contexto histórico del conflicto entre Estados Unidos y China suponeel principio del fin de medio milenio de dominación del mundo Occidental, por una dinastía de estados desde Portugal hasta Estados Unidos.El ascenso de China como superpotencia económica y tecnológica abre una tercera fase del declive del imperio Occidental, después dela descolonización y el retroceso de los intentos fallidos de occi-dentalizar el mundo no Occidental tras la victoria de la Guerra Fría.El fin del imperio Occidental probablemente llegará en este siglo, salvo que unaguerra nuclearmodifique el curso de los acontecimientos de forma abrupta; en cualquier caso, las previsiones de futuro constituyen siempreuna pregunta abierta.
The 21st century will be the hottest century in thousands of years, and the world’s social landscape is volcanic. Global politics and social relations will be dominated by two issues, the climate crisis and the US-China rivalry. This paper analyses their passage through the «inequality pandemic» of Covid-19, weakening some pertinent forces and strengthened others, and further the contexts and prospects of the climate crisis and the US-China conflict. Governmental response to the pandemic terminated the global regime of neoliberalism and untrammelled market globalization, which have been succeeded by geopolitical conflict and great power domestic mobilization. The profound technological and social transformations needed to meet the climate crisis are likely to remain in the hands of politics as usual, with messy but hardly apocalyptic results. The historical context of the US-China conflict is the half millennium of Western world domination, by a dynasty of states from Portugal to USA. The rise of China as an economic and technological superpower opens a third phase of the decline of the Western empire, after decolonization and the blowback from the failed attempts to westernize the non-Western world after the Cold War victory. The end of the Western empire will probably come in this century –short of nuclear war–, but what will succeed it is an open question.
El Sistema de Estados Internacional después del Neoliberalismo: Europa entre la Democracia Nacional y la Centralización Supranacional
Authors: Streeck Wolfgang 
Published: October 2021

En 1945 Karl Polanyi esbozó una visión de un sistema estatal global en tiempos de paz con una economía política en la que los países pequeños podrían ser soberanos y democráticos. Este ensayo ofrece una perspectiva histórica y comparativa entre el pasado y el presente a la luz del pensamiento polanyiano. Se presta especial atención a la historia de la Unión Europea, que tras el fin del comunismo se convirtió en un pilar del proyecto neoliberal y culminó con la restauración de un patrón oro internacional bajo la Unión Monetaria. Durante la crisis de 2008 el avance del neoliberalismo se enfrentó, no obstante, a la resistencia «populista», a la austeridad y al cambio de gobernanza del nivel nacional al supranacional. El artículo explora las perspectivas de los intentos actuales de reemplazar la «Europa social» y las narrativas economicistas trickle-down, y de la formación de superestados europeos, que han perdido toda credibilidad, por una historia sobre un ejército europeo como condición necesaria para una defensa exitosa del European way of life.
In 1945 Karl Polanyi outlined a vision of a peacetime global state system with a political economy in which small countries could be both sovereign and democratic. The present essay reviews developments between then and now in the light of Polanyi’s analytical framework. Particular attention is paid to the history of the European Union, which after the end of Communism turned into a mainstay of the neoliberal project, culminating in its restoration of an international gold standard under Monetary Union. In the crisis of 2008 the advance of neoliberalism got stuck due to «populist» resistance to austerity and the shift of governance from the national to a supranational level. The paper explores the prospects of current attempts to replace the «Social Europe» and «trickle-down» narratives of European superstate formation, which have lost all credit, with a story about a European army as a necessary condition of a successful defense of «the European way of life».
Le « visage » du colonialisme

Published: October 2021

L’arrivée de la Compagnie de la Baie d’Hudson et des traiteurs de fourrures chez les Cris de l’Eeyou Istchee (est de la Baie James) et les Inuit du Nunavik a précipité de nombreux changements dans la vie des populations locales, parmi lesquels le métissage d’hommes britanniques et de femmes autochtones qui a conduit à plusieurs centaines d’années d’unions d’ascendance mixte. Cette cohabitation et ce métissage se sont produits partout dans le pays de la traite des fourrures et, dans deux régions utilisées comme contrastes, la Rivière Rouge et l’ouest de la Baie James, un nouveau peuple apparut, d’abord connu sous le nom de Métis dans la colonie de la Rivière Rouge. En revanche, aucune société nouvelle de ce genre n’a vu le jour dans les deux régions du Québec. Pour comprendre les circonstances de ce non-événement, il est essentiel de savoir comment les relations personnelles se sont déroulées dans les communautés des postes entre les populations autochtones, les Eurocanadiens et la population mixte. Aucun trait distinctif fondamental n’a été discerné en Eeyou Istchee ou au Nunavik, alors que d’autres facteurs sont considérés comme ayant provoqué l’émergence d’un nouveau peuple à l’extérieur du Québec.
Evaluation of Learning Environment among First year MBBS and BDS Students at a Private Malaysian University
Authors: George Sherly Deborah , Maung Theingi Maung , Narayanam Harini 
Published: October 2021

Background: The learning environment has a significant impact on the academic success and learning process of students. Implementing a high-quality, student-centered curriculum demands an assessment of the educational environment. The focus of this study was to compare the learning environments of first-year medical and dental students at a private Malaysian University using the Dundee Ready Educational Environment Measure (DREEM) questionnaire, a validated method for evaluating educational environments.
Methodology: A cross-sectional analytical study was undertaken with students who agreed to participate. The trial lasted three months. After obtaining consent from students for participation, demographic information was gathered. Students in the lecture hall were given physical copies of the DREEM questionnaire to assess their learning environment. A total of 225 students participated, and IBM SPSS version 23 was used to analyze the data. The Chi-square and Student t tests were employed to establish the existence of an association or difference between two variables.
Result: A total of 225 students were involved in this study showing 100% response rate. The total score indicated that the majority (84%) regarded the educational environment was outstanding, 15.56 percent had a more promising opinion, and a very small percentage (0.44%) believed the educational environment was terrible. In this study with noteworthy findings, medical students were happier with their lecturers and with their own academic abilities than dental students. The weakest 19 questions were identified. Most respondents had extremely favorable attitudes toward the educational environment, followed by a moderately favorable opinion. Less than 1% of pupils exhibited a negative attitude.
Conclusion: In this study, perceptions of the educational environment was satisfactory for both medical and dental students, but more positive for medical students. Measures must be taken to improve the scores and ensure that the scores are consistent across both faculties.
Application of Trichoderma viride and Bacillus subtilis Modulates Antioxidant System in Mustard (Brassica juncea) under Water-deficit Stress
Authors: Kavita . , Mohan Krishna 
Published: October 2021

Water-deficit stress is an important concern worldwide that reduces crop yield and quality. Mustard is an important oilseed crop of India which is adversely affected by water-deficit stress in terms of growth and yield. Tolerance to water-deficit stress is correlated with the redox regulatory and antioxidant system. To mitigate negative effect of water-deficit stress, field experiment was conducted at Dholi (Muzaffarpur), Bihar during 2019-20 with an aim to study the effect of microbes on antioxidant systems in mustard grown under water-deficit stress vis-à-vis normal irrigated conditions. Pre-screened contrasting genotypes (tolerant ‘NPJ 214’ and sensitive ‘TM 179’) were sown in the experimental farm using factorial experiment in randomized block design with three replications. The treatments (12) comprised of two factors viz., genotypes (2) and microbial inoculants along with control (3) sown under normal ‘irrigated’ and ‘water-deficit stress’ conditions. Soil inoculation microbes Bacillus subtilis and Trichoderma viride was done 35 days after sowing and was compared with non-inoculated control. Results revealed that the activity of antioxidative enzymes viz., catalase and peroxidase increased under water-deficit stress; the increase was reduced by the application of B. subtilis and T. viride in both tolerant and sensitive genotypes, and more pronounced in the sensitive genotypes. Similar results were recorded with respect to lipid peroxidation and proline content. Increase in concentration of stress-induced metabolites was less in colonized plants of mustard indicating modulation of antioxidant system. The maximum ameliorating effect was observed with application of T. viride which could be an important tool in alleviating the adverse effects of water-deficit stress in mustard.

This study assessed the effects of Sarcocephalus latifolius Afzel. Ex R.Br. leaf powder on the kidney function of alloxan-induced diabetes rats.
Forty-five healthy female albino rats were used in the experiment and assigned into 9 different groups. Diabetes was induced intravenously with 150 mg/kg body weight alloxan. Normal and diabetic rats were administered orally with 300, 600, 750mg/kg/ b.w of S. latifolius. After 28 days, the animals were sacrificed and blood with the kidney were harvested for biochemical and histological studies.
In our result, significant (p<0.05) increase was observed in creatinine concentration of diabetic rats, which was significantly (p<0.05) decreased upon administration of 300 and 750 mg/kg body weight of Sarcocephalus latifolius leaf powder. No significant (p>0.05) difference was observed in the urea concentration of all the groups. Significant (p<0.05) difference in sodium concentration was only observed between the diabetic untreated and metformin treated groups whereas, potassium concentration varied significantly (p<0.05) across the groups. Certain degenerative changes in the kidney of normal and diabetic rats treated and untreated with S. latifolius leaf powder were observed but at a lower degree in the group treated with the 300 mg/kg/bw of the leaf powder. The result of this study showed the possible renal toxicity potential of the plant at high dose.
