Self-directed Learning (SDL) and Development of Competencies among Students of the University of Bamenda
Authors: Len Kibinkiri Eric , Tieme Kunike 
Published: August 2022

Purpose: This study examines the relationship between self-directed learning (SDL) and development of competencies among students of the University of Bamenda (UBa).
Methodology: The argument for this study anchored on Vygosky’s Social Constructivism Theory, Cognitive Apprenticeship Theory of Collins et al., and Tchombe’s Mediated Mutual Reciprocity Theory. A correlational survey research design, with a quantitative approach for data collection was used. A sample of 254 students, derived using two probability (stratified random and simple random) sampling techniques and two non-probability (convenience and purposive) sampling techniques, participated in this study. Data obtained were analyzed descriptively and inferentially. The Spearman’s Rho correlation test was used to test the specific research hypotheses.
Findings: Findings showed that, there is a significant and positive relationship between identification of learning problems and development of competencies among students (P<0.000) (R=0.410**). Similarly, findings on hypothesis two showed that there is a significant relationship between application of appropriate learning strategies and development of competencies among students (P<0.027)(R=0.139*). Lastly, findings on hypothesis three showed that there is a significant relationship between assessment and evaluation of learning and development of competencies among students (P<0.000) (R=0.525**).
Recommendations: Based on these findings, it was recommended that there is need for bias towards action, a competence-based curriculum, and respect of format, frequency and feedback for assessment and evaluation. Additionally, Universities should adopt the SDL model as a learning strategy and develop strategies to overcome obstacles that hinder its application, as well as train teachers on the didactics of the blended learning model.

Purpose: The biodegradation effects of agro-wastes (poultry droppings and cow dung) on some physico-chemical properties of the effluents were assessed. Methodology: Triplicate slurries (1:3 w/v) of five ratios of poultry droppings and cow dung: (0:1, 1:3, 1:1, 3:1 and 1:0 as treatments A, B, C, D and E) were separately fed into 13.6L locally constructed digesters, under strict anaerobic condition. They were kept for eight weeks retention period. Separate fractions of the undigested and digested treatments were subjected to standard assay procedures to determine their C, N, heavy contents, chemical oxygen demand (COD). The average weekly temperature and the pH before and after digestion of the media were measured. Findings: The cumulative biogas yield was in the order of treatment C (2961.0ml) >D(2241.7ml) > E(2197.9ml) > A(2079.0ml) > B(2031.1ml), based on the following mixing ratios 1:1>3:1>0:1>1:0>1:3. The gas production was affected by weekly temperature variation, which peaked at the mesophilic range (40.5±0.3 ̶ 44.1±0.3OC). The resultant pH of the digestates was in the order of 1:3 > 3:1 > 1:1 > 0:1 > 1:0. There was a general reduction in heavy metal contents for all treatment digestates, except Cu, with 200.00, 35.82 and 7.34% as %increases in treatments A, E and C respectively. All treatments indicated reduction in C:N ratios, ranging from 7.93 ̶ 13.02, in the order of 3:1>1:1>1:3>0:1>1:0. Similarly, there was decrease in COD contents for all treatments due to AD. Consequently, the percentage COD reduction (%CODR) was in the order of treatment D(53.70%) > E(34.15%) > C(29.63%) > A(25.81%) > B(19.23%). Unique contribution to theory, practice and policy: The biodegradation process had provided an effective means of alternative energy production, agricultural waste management initiative, which would ensure bioremediation, sustainable public health and environmental management

Purpose: The research study aimed to determine the efficacy of Urena lobata in phytoremediation of spent engine oil polluted soil of Makurdi, Nigeria as to determine the amount of some inorganic pollutants (Cd, Pb, As and Cr) removed from the soil by the annual plant with time.
Methodology: Urena lobata was grown in twelve (12) Plastic containers filled with four kilograms (4 kg) of sandy-loam soil contaminated with 0 mL, 20 mL, 40 mL, 60 mL, 80 mL and 100 mL and monitored for twelve weeks (12) after planting.
Findings: The tissue analysis of heavy metals shows that Urena lobata has the highest percentage absorbance and remediation capacity of arsenic (0.06 mg/kg) with percentage absorbance of 37.5 % and followed by cadmium 0.04 mg/kg of pollutant with percentage absorbance of 32.56 %. Equally, from the result and analysis obtained on remediation of lead pollutant, Urena lobata has remediation capacity of 0.11 mg/kg with percentage absorbance of 8.53 %. Also, Urena lobata has absorbance and remediation capacity of chromium pollutant with the mean tissue concentration level of 0.26 mg/kg. The absorption rate by the test plant measured were spent engine oil concentration level dependent. Finally, the results showed that the studied plant (Urena lobata) screened for total metal concentration showed value of bio-concentration factor (BCF) < 1 for all heavy metal pollutants, and also high value of translocation factor (TF) > 1 in the following order; Pb (2.000) > As (1.667) > Cr (1.567) > Cd (1.500) mg/kg and as a consequence Urena lobata plant was efficient in translocation of metal pollutants from roots to shoots.
Unique contribution to theory, practice and policy: Urena lobata can then be considered as potential candidates for phytoextraction and phytoremediation of soils contaminated with Cd, Pb, As and Cr. Facility owners and industrialists should adopt and invest on the use of phytoremediation technologies in the remediation of polluted sites with spent engine oil as the technology can remediate more than one pollutant at a time and environmentally friendly.

Pueblos y agricultura a fines del siglo XIX: los ensanches de ejidos en la provincia de Buenos Aires
Authors: Barcos María 
Published: August 2022

Durante la década de 1880 la agricultura pampeana experimentó un crecimiento importante gracias a una serie de transformaciones que fueron operadas inicialmente entre 1860 y 1870. Dicho crecimiento fue regionalmente diferencial puesto que en Buenos Aires solo se habían consolidado los antiguos polos de producción cerealera que, con un sendero paulatinamente decreciente en términos relativos, no podían acercarse a los niveles de producción de las colonias agrícolas de la provincia de Santa Fe. Esta situación “negativa” era evidente para la mayoría de los legisladores bonaerenses quienes, como modo transformar la situación de la agricultura sin entorpecer la práctica ganadera, propiciaron proyectos para extender las áreas ejidales mediante los ensanches de ejidos. De esta manera, entre 1881 y 1890 se ensancharon los ejidos de casi 30 partidos de la provincia de Buenos Aires. En este trabajo se analizarán las causas por las que se seleccionaron los partidos, las características de esos ensanches y se estimarán los resultados para el fomento de la población y el cultivo. Las fuentes utilizadas son variadas: duplicados de mensura, notas de los agrimensores, debates parlamentarios, expedientes de tierras y censos económicos.
La reforma agraria en las políticas peronista, desarrollista y en la Federación Agraria Argentina, 1943-1959
Authors: Olivera Gabriela 
Published: August 2022

En los años que siguieron al Grito de Alcorta continuaron los conflictos. Hubo un ciclo general de huelgas y movilizaciones obreras durante 1917-1921. A éste se sumó la reanudación del conflicto chacarero, el de estibadores, carreros y braceros. Entre otras cuestiones, este ciclo histórico culminaría con la sanción de la ley nacional de arrendamientos de 1921, primera norma nacional destinada a regular las relaciones entre propietarios y arrendatarios rurales. Esta marcó un hito en la historia del movimiento chacarero, ya que implicó el reconocimiento estatal de un conjunto de derechos chacareros y promovió el acceso a la propiedad de la tierra y la capitalización por parte de algunos segmentos de la agricultura familiar.Es nuestro propósito en este artículo estudiar qué representaciones, qué contenidos comprendían los lineamientos de este proyecto, qué acciones (disruptivas o de concertación con las agencias estatales) se desplegaron en pos de su concreción, cómo los discursos agraristas contribuyeron a darle contenido y legitimidad, de qué manera las políticas públicas incentivaron o no este propósito, cuáles fueron los mecanismos institucionales que las diferentes agencias estatales pusieron en marcha para apuntalar o para obturar su concreción.
Evaluación e ideología ¿hacia una cultura dirigida?
Authors: Stein Eduardo 
Published: August 2022

Este trabajo es el texto de la ponencia que el autor presentó en el VII Seminario Latinoamericano de Teleducación Universitaria, realizado en la UCA, San Salvador, del 22 al 28 de noviembre de este año 1979. Apartándose de las formas expositivas tradicionales el trabajo expone por medio de una narración ficticia toda la gama de problemas conceptuales y algunos operacionales por los que han pasado la inmensa mayoría de proyectos de educación a distancia en América Latina, relativos al problema de evaluación e imposición cultural. Puede verse como una historia de dificultades sucesivas por las que, a pesar de instrumentos estadísticos bastante desarrollados, ha pasado la evaluación de proyectos y programas teleducativos, cuando se trata de mediciones cualitativas sobre cambios de comportamiento y de conciencia; procedimientos evaluativos en los cuales es imposible escapar de marcos ideológicos.

Se estudió la respuesta de corderos Pelibuey (P), Blackbelly (BB) y Dorper x Pelibuey (DxP) a una infección experimental con nematodos gastrointestinales (NGI). Se utilizaron 21 corderos P de dos meses de edad, 15 BB de tres meses de edad, y 14 DxP de dos meses de edad, con pesos vivos (PV) de 12.0±3.2, 13.6±3.9, y 13.0±3.6 kg, respectivamente. El experimento se efectuó en dos etapas de 30 días cada una, la primera en pastoreo y la segunda en confinamiento. En ambas etapas, los corderos se infectaron con 3,000 larvas (L3) de una mezcla de NGI. Cada siete días se recolectaron muestras de heces para contar el número de huevos por gramo de heces (HPG) y sangre para medir el volumen celular aglomerado (VCA), además de registrar su PV, condición corporal (CC) y la coloración de la mucosa ocular (CMO). Los corderos BB y DxP tuvieron mayores conteos fecales (5,259±654 y 5,515±654 HPG), mientras que los P, los menores (3,252±515, P<0.01). En el VCA, los corderos más afectados (P<0.01) fueron los BB (0.257±0.005), ya que los P y DxP tuvieron mayores valores (0.281±0.004 y 0.275±0.005). La resistencia de los corderos P a los NGI fue superior a la de los corderos BB y DxP.

Published: August 2022

Introduction Spinal stenosis has a wide range of causes including disc herniation, facet hypertrophy, degenerative spondylosis, facet cyst, ossification of the ligamentum flavum (OLF) and ossification of the posterior longitudinal ligament (OPLL). We present three cases of diffuse spinal hyperostosis causing severe spinal stenosis and myelopathy, which demonstrate a unique association between obesity and a novel syndrome of hyperostosis. Case Presentation This report describes 3 morbidly obese patients with diffuse spinal hyperostosis causing critical thoracic stenosis. Their presenting complaints focus on lower extremity weakness and the CT/MRI imaging is striking for diffuse hyper-ossification at thoracic levels. Two patients were subsequently managed with spinal decompression, and one patient was managed non-operatively. Discussion Metabolic changes associated with obesity may result in diffuse hyperostosis with ligament ossification and spinal stenosis. Pre-operative imaging is essential to identify the degree of ossification and potential dural involvement as this may complicate management.
Institutionalizing Afro-Asianism: Lotus and the (Dis) Contents of Soviet-Third World Cultural Politics
Authors: Fatima Maryam 
Published: August 2022

ABSTRACT
This article examines the Afro-Asian Writers’ Association’s (AAWA) magazine, Lotus, as an example of the cultural discourse of Afro-Asianism and the logistical and political challenges of institutionalizing a Third World literary canon within the broader context of Cold War alliances. The author's focus on the magazine’s conceptual vocabulary and its internal mechanisms reveals how anticolonial writers and cultural actors brought their own different (often, competing) versions of Marxism and varying degrees of alignment with Soviet-style socialism to the project of cultural decolonization and contributed to a global socialist order. Concerns of literary form, political liberation, and the context of noncommercial patronage shaped an all-encompassing cumulative aesthetic that was not always aligned with Moscow mandates. Her reading of the Lotus archive also draws out the frictions between various geopolitical pivots of the Afro-Asian—a focus on nation, civilization, race, and the larger socialist internationalism—to contribute to studies of the political entanglements between postcolonial and postsocialist studies that can offer insights into current geopolitical predicaments, especially for regions that continue to suffer from new and old forms of occupation and imperialism.
The Socialist Leader in Film: Sergiu Nicolaescu’s Hot Days in Romania and Post-Maoist China
Authors: Tion Lucian 
Published: August 2022

ABSTRACT
This article comparatively explores the reception of Sergiu Nicolaescu’s film Zile fierbinți (Hot Days, 1975) in socialist and postsocialist Romania and China. Received as a propagandistic film in one postsocialist context, the film is understood as a gesture toward social change in another. While the film began to be considered a paragon of propagandistic indoctrination in Romania after the fall of communism, in China Nicolaescu’s work was and continues to be interpreted as a celebration of the individual under socialism and, at the time of its screening, resonated with the restructuring of the communist system during the Deng Xiaoping reform era. Drawing on 1970s Romanian film criticism, the author shows that the postsocialist-era reading of the film’s protagonist as an authoritarian symbol of Romania’s political dictatorship misses that socialist realism and the film de actualitate genres played an important role in negotiating a working-class response to the one-party state, while also gesturing toward certain reforms of Romanian state socialism. The author also reinterprets the figure of the film’s protagonist, the socialist leader, as an invitation for more active political engagement and as a symbol of the potential restructuring of the Romanian economy along the more progressive lines of Yugoslavia’s “worker self-management” and Hungary’s “Gulash Communism.”
Cold War Solidarities and Twenty-First-Century Frayed Alliances: Romanian-Ghanaian Vantage Points
Authors: Popescu Monica 
Published: August 2022

ABSTRACT
During the Cold War, socialist countries in the Eastern Bloc forged fraternal relations with newly independent states on the African continent and other parts of the Third World. These alliances translated into economic exchanges, political and ideological ties, and cultural solidarities. Oftentimes subsumed under the rubric of internationalism, these understudied cultural exchanges reflect both the forward thinking elements of global socialism as well as the paternalist and condescending aspects of relations between the Second and the Third Worlds. In order to analyze the legacies of these solidarities in the twenty-first century, the author looks at the work of Wanlov the Kubolor, which is the stage name of Emmanuel Owusu-Bonsu, a Ghanaian-Romanian musician, poet, film director, and activist. Describing himself as an “African Gypsy” and a peripatetic trickster (a “kubolor”), Wanlov draws on Ghanaian and Romanian artistic traditions to forge a unique perspective on postsocialist societies, from the margins of the capitalist world-system. The work of artists such as Wanlov the Kubolor presents a clear-eyed East/South perspective on global phenomena: consumerism, the quick cooptation and taming of oppositional aesthetics into commercial art, racism, and class distinctions, yet also possible new directions for activism and resistance.
Transnationalizing Memories of Post/Socialism: Diasporic Graphic Lives
Authors: Luca Ioana 
Published: August 2022

ABSTRACT
The article focuses on The Wall: Growing Up Behind the Iron Curtain (Peter Sís, 2007) and Marzi (Sylvain Savoia and Marzena Sowa, 2004–2017), two widely translated autobiographical comics written in English and French, respectively, as an entry point into the afterlives of European state socialisms in global contexts. The author examines how Sís, a Czech-born illustrator and children book author, who defected to the United States, and Sowa, a Polish-born writer who left for France, remember their lives under state socialism, and how they make them legible to present-day transgenerational and transnational audiences. The author explores how comics, specifically the seriality, multimodality, and the meanings created at the intersection of texts and images, undermine the cultural scripts which inform the narratives of these two diasporic artists. By focusing on paratextual elements, the author also demonstrates that the transnational trajectories of the two works are path-dependent on mainstream tropes about state socialism. Lastly, given that the two comics feature internationally in school curricula and are adopted by teachers as important methodological tools, the author argues for the crucial importance of comics and life writing pedagogy when teaching graphic autobiographies about post/socialism.
On the Object of History and Doing History in the Intellectual History of Muslim West Africa
Authors: Mogomotsi Olerato Kau 
Published: August 2022

Abstract
Haydon White’s Metahistory (1973) interprets representations of history as inherently reflecting historians’ subjectivity. That is, the modes in which historians represent history are significantly determined and grounded by their ideological commitments. In this article, I offer a metahistorical analysis of the modes of doing history undertaken by the African Islamic intellectual historians Ousmane Kane and Souleymane Bachir Diagne. I critically evaluate the consistency between the object of history as they assume it to be and the discourses they (re)produce, taking account of their ideologically grounded mode of realizing their chosen object of history. Taking the general object of history for the African intellectual to be the resistance of the colonial library, I argue that, in their pursuit of this object of history, Kane and Diagne fall short owing to their use of the Islamic library to assert the existence of an African intellectual history.
