La llegada como migrante latinoamericana a la ciudad de La Plata, desde el inicio del recorrido de un colectivo te presenta un paneo de su historia social y política desde la última dictadura cívico militar, hasta la construcción de la democracia como proceso vigente, través de símbolos puestos en lugares públicos. Sin la necesidad de googlear o buscar un libro, sabemos que hubo 30 mil desaparecidos, que hay familiares que los siguen buscando, que existe una latente lucha por la verdad, memoria y justicia y que hay víctimas de la violencia policial con cientos de desparecidos y desparecidas en democracia. El siguiente ensayo explora esta experiencia migrante y las marcas territoriales son expresiones de memoria colectiva que revelan información ausente en los medios dominantes. Específicamente abordamos el caso de Miguel Bru, un estudiante desaparecido en 1993, cuya imagen está plasmada en espacios públicos, incluso en la facultad de Periodismo de la Universidad Nacional de La Plata, que se identifica con su historia. Estas manifestaciones no solo conmemoran, sino también informan y crean identidad, subrayando la importancia de mantener viva la memoria histórica.
Comparative Analysis of the European Centralised Public Procurement
Authors: Tátrai Tünde , Vörösmarty Gyöngyi 
Published: August 2023

Abstract
When analysing centralised public procurement models and solutions from the public administration point of view, attention needs to be paid to the specific features of public procurement as well as the institutional characteristics of the major central procurement organisations. In this paper, central procurement organisations in 11 European countries were compared based on interviews according to their activities, market positions and institutional characteristics. We shall address the issue of efficiency and stability of organisational structures by comparing the practice of the Central and Eastern European (CEE) and non-CEE European Countries. This comparison analyses the differences of the countries’ centralised public procurement structures and reveals the diversity of analytic criteria, underlining that the legal regulatory background to public procurement is not necessarily predominant in determining specific features and characteristics. The stability and market-oriented characteristics of a centralised public procurement system have an impact on the innovativeness of central purchasing bodies (CPBs) and on the development of their service provider nature, which should be taken into account by the CEE countries with a less-developed public procurement culture.

Published: August 2023

Hydram pump is a solution to overcome the problem of water demand, especially for highland areas. Hydram pumps can be used for rice field areas because they do not require an electric energy source. Operating parameters at the hydram pump greatly affect the efficiency of the hydram pump. In practice in the field, altitude is not difficult to obtain, especially for mountainous areas. However, for some highland areas, often to get a certain height must be with a large elevation distance hydram pump to water sources. In this research, a change in the angle of inlet variation will be conducted on the efficiency that occurs. So that with this research, it can be a benchmark for determining the distance of a hydram pump to a water source. The highest water discharge that can be generated from a 1 in size PVC hydram pump, 2.75 m inlet height, 5 m outlet height is 1.5 x 10-5 m3/s. while the lowest water discharge in the test carried out is 0 m3/s at the number of pendants 1 and the pump inlet angle is 45°. The inlet angle greatly affects the resulting flow rate. The inlet angle of 30° results in a higher water flow rate of 1.44x10-5 m3/s at the number of pendulum 2 compared to the 45° inlet angle which only gets 9.44x10-6 m3/s even up to 0 m3/s at the number of pendulum 1.

Storytelling Research: Implications for the Broader Higher Education System in South Africa
Authors: Masoga Mogomme 
Published: August 2023

The present investigation aims at promoting storytelling as a critical research discipline within the broader higher education system in South Africa. During the apartheid era and in democratic South Africa, storytelling was (and is) not part of the agenda for consideration in the broader higher education system. This status quo was due to multifarious factors including a myopic view of traditional scientific research. In the pre-colonial African communities, stories were told in the evening in the rural home around the fire to capture the attention of and educate the younger family members. Members of the community and adults within a family (e.g., mother, father, uncle, aunt, etc.) usually told stories which drew themes from lived realities. In their entirety, stories were posited towards teaching important lessons about life in general. Some stories were simple fiction-oriented, while others were non-fiction and premised on empirical life actualities. A story would predicate the characters as actual people in a real-life situation. In our modern digital era, some stories are stage-played or dramatised on television. Today, storytelling also involves public speaking by individuals known as “motivational speakers.” Among African societies, most stories featured themes involving a human being with wildlife species such as lion, leopard, baboon and wild rabbit, and many others. To make the discussion on storytelling more vivid and meaningful, an autoethnographic reflection on the story of the man and the leopard was used as an example in this article. In view of the reader-response concept, an articulation of the main ideas unfolding in the story follows the example presented in this paper. The study is based on a narrative analysis as an approach. A narrative analysis comprises literary genre as a theoretical framework.
