The material of Glosselytrodea from the Molteno Formation (Triassic, South Africa), consisting of two specimens, is herein studied. A preliminary comparative analysis is conducted based on the new material and new data on Polycytella triassica Tillyard, 1922 (Triassic, Australia), highlighting the relevance of the width of the area anterior to RA (particularly, opposite the end of ScP), an area very broad in Polycytella Tillyard, 1922, Argentinoglosselytrina Martins-Neto and Gallego, 2001 (Triassic, Argentina) and in the new material from the Molteno. An emended diagnosis of the Polycytellidae is elaborated accordingly. The material from the Molteno is assigned to Polycytella rasnitsyni gen. et sp. nov. and Moltenojurina parva gen. et sp. nov., the latter being the smallest Glosselytrodea known to date. As newly delimited, the Polycytellidae are strictly Gondwanan.

Informatization of education has been going on for 30 years. During this time, a good material and technical base appeared in schools, there are repositories of e-learning resources to which teachers have access. However, it is difficult to use these e-learning resources due to their too large number and not always high level. It is advisable to introduce a system of reviews and recommendations, to conduct a comparative analysis, as well as to make reviews of resources on a particular subject/topic. In addition, the demand for e-learning resources is affected by the fact that education authorities encourage not so much the use of e-learning resources as their development by the teacher himself. In general, the load on teachers has increased instead of the promised saving of time and effort when using the e-learning resources. At the same time, many e-learning resources are not very effective, since they do not meet the requirements of cognitiveness (they contribute not to learning, but to simple memorization of the material). It is necessary to explore the process of learning new material: this will allow you to create cognitive e-learning resources and other resources that would help you with equal probability to successfully acquire new knowledge for students belonging to different psycho-types. At the initial stage of the study of any subject, it is more expedient to use the usual “paper” method, that is, a textbook and not overload the student’s brain with excessive information. Only when he has mastered the basic provisions, we can turn to e-learning resources, bearing in mind that they must be cognitive, that is, they are aimed at logical perception and rapid intuitive learning, only in this case e-learning resources can be considered effective. The conclusion is formulated that cognitiveness is the next stage of informatization of education after the stage of electronization.

Climate change is a financial factor that carries with it risks and opportunities for companies. To support boards of directors of companies belonging to all jurisdictions, the World Economic Forum issued in January 2019 eight Principlescontaining both theoretical and practical provisions on: climate accountability, competence, governance, management, disclosure and dialogue. The paper analyses each Principle to understand scope and managerial consequences for boards and to evaluate whether the legal distinctions, among the various jurisdictions, may undermine the application of the Principles or, by contrast, despite the differences the Principles may be a useful and effective guidance to drive boards' of directors' conduct around the world in handling climate change challenges. Five jurisdictions are taken into consideration for this comparative analysis: Europe (and UK), US, Australia, South Africa and Canada. The conclusion is that the WEF Principles, as soft law, is the best possible instrument to address boards of directors of worldwide companies, harmonise their conduct and effectively help facing such global emergency.

From a feminist institutionalist perspective, this article engages in a comparative analysis of South Africa, one of the only post-transition democracies where women organized as a distinct interest group representing gender interests were able to negotiate and gain access to political power, and India, where women’s participation was predominantly as ‘nationalist women’. It argues that constitution drafting is a decisive critical juncture when descriptive representation can be translated very effectively into the substantive representation of women as equal citizens, provided women qua women and as gender-conscious agents are able to intervene to promote the cause of their effective political participation.

Каждый имеет право на жилище. Никто не может быть произвольно лишен жилища. В статье проанализированы особенности реализации универсального права человека на жилище в отдельных странах (на примере Нидерландов и ЮАР), принадлежащих к разным правовым семьям. Everyone has the right to housing. No one can be arbitrarily deprived of their home. The article analyzes the features of the implementation of the universal human right to housing in individual countries (on the example of the Netherlands and South Africa) belonging to different legal families.
