Research for development approaches in mixed crop-livestock systems of the Ethiopian highlands

Million Gebreyes James Hammond Lulseged Tamene Getachew Agegnehu Rabe Yahaya Anthony Whitbread (2023, [Artículo])

This study presents processes and success stories that emerged from Africa RISING's Research for Development project in the Ethiopian Highlands. The project has tested a combination of participatory tools at multiple levels, with systems thinking and concern for sustainable and diversified livelihoods. Bottom-up approaches guided the selection of technological interventions that could address the priority farming system challenges of the communities, leading to higher uptake levels and increased impact. Joint learning, appropriate technology selection, and the creation of an enabling environment such as the formation of farmer research groups, the establishment of innovation platforms, and capacity development for institutional and technical innovations were key to this study. The study concludes by identifying key lessons that focus more on matching innovations to community needs and geographies, systems orientation/integration of innovations, stepwise approaches to enhance the adoption of innovations, documenting farmers' capacity to modify innovations, building successful partnerships, and facilitating wider scaling of innovations for future implementation of agricultural research for development projects.

Abduction according to Peirce: reflections from the south on the crisis of representation brought on by COVID-19

Paulina Aroch (2023, [Artículo, Artículo])

In this article, I reflect on the importance of abductive thinking for processes of material and conceptual reinvention in the context of the current public health crisis. Inseparable from the climate change engulfing the planet, this crisis provides the basis for a semiotic revolution. Therefore, I interrogate Peirce’s work without losing sight of my own time and place of interlocution. COVID-19 has brought with it a crisis of representation which, in contrast to that unleashed by the Holocaust and World War II, and to which the Frankfurt School responded, demands responses from the Global South. Beginning from Dussel’s call to defend life as a matter of ethical urgency in the face of its irresponsible objectification within colonial capitalist modernity –which arguably triggered the pandemic–, I trace a “nocturnal map” that registers the present meaning-making crisis, and allows for a reimagining and remaking of the world from elsewhere.

Disruptive approach to integrate data in a digital environment: progress report CIMMYT-Bluenumber 2023

Andrea Gardeazabal (2023, [Documento de trabajo])

This report describes the process carried out a pilot project to evaluate a scalable disruptive approach to integrating data for agronomy research that also incentivizes sustainable production and enables traceability using open data sharing protocol with self-sovereign identity (SSI).

Potential impact of prosthetic biomaterials on the periodontium: a comprehensive review.

NATIVIDAD CASTRO ALARCON Artak Heboyan Gustavo Fernandes Norma Samanta Romero Castro (2023, [Artículo])

The success of a prosthetic treatment is closely related to the periodontal health of the individual. The aim of this article was to review and present the importance of prosthetic restorative materials on the condition of the periodontium, the changes that occur in the composition of the subgingival microbiota and the levels of inflammatory markers in gingival crevicular fluid. Articles on the influence of different prosthetic restorative materials on subgingival microbiota and proinflammatory cytokines were searched for using the keywords ¿prosthetic biomaterials¿, ¿fixed prosthesis¿, ¿periodontal health¿, ¿subgingival microbiota¿, ¿periodontal biomarkers¿ and ¿gingival crevicular fluid¿ in PubMed/Medline, Science Direct, Scopus and Google Scholar. The type of material used for prosthesis fabrication together with poor marginal and internal fit can result in changes in the composition of the subgingival microbiota, as well as increased accumulation and retention of dentobacterial plaque, thus favoring the development of periodontal disease and prosthetic treatment failure. Biological markers have helped to understand the inflammatory response of different prosthetic materials on periodontal tissues with the main purpose of improving their clinical application

in patients who need them. Metal-free ceramic prostheses induce a lower inflammatory response regardless of the fabrication method; however, the use of CAD/CAM systems is recommended for their fabrication. In addition, it is presumed that metal-ceramic prostheses cause changes in the composition of the subgingival microbiota producing a more dysbiotic biofilm with a higher prevalence of periodontopathogenic bacteria, which may further favor periodontal deterioration.
