An Analysis of the Entrepreneurial Ecosystem of Malawi: The Global Entrepreneurship Index (GEI) Approach
Authors: Pobee Frederick , Mphela Thuso
Published: March 2021

The research paper provides an in-depth analysis of the entrepreneurial ecosystem of Malawi. Employing the Global Entrepreneurship Index (GEI) methodology, the findings reveal a weak entrepreneurial ecosystem with a GEI score of 12.2 out of a possible 100. The relationship between the GDP per capita and the three entrepreneurship sub-indices, thus, attitude, ability, and aspiration are very weak and fall well below global average trends. Unfortunately, despite the high total entrepreneurship activities (TEA) in Malawi, this leads to little contribution to the country's GDP per-capita – a common phenomenon in many developing countries. At the pillar level, Malawi’s performance is a mixed bag, however, with most pillars performing not only poorly but below world averages. Despite the general positive perception of entrepreneurship by citizens, the country’s weak entrepreneurial ecosystem has failed to harness the propensity to develop new products and adopt new technologies for innovation and high growth entrepreneurship. From a policy intervention perspective, Malawi needs to focus most of its efforts and investments in five areas that include start-up skills, risk acceptance, high growth, risk capital, and human capital to improve the country's GEI score by 0.02.

The three bioactive components isolated included: component A (major phytochemicals were Bis (2-ethylhexyl) phthalate (16.36 %), 9,12-Octadecadienoic acid, ethyl ether (14.77 %) and 9.cis., 11.trans.-octadecadie noate (14.77 %), component B (major phytochemicals were 9,12-Octadecadienal (Linoleic acid) (40.98 %), Octadecanoic acid (Stearic acid) (9.26 %), Undecanoic acid, 10-bromo- (10-bromoudecanoic acid) (9.26 %) and n-Hexadecanoic acid (Palmitic acid) and component C (cis-9-octadecenoic acid (Oleic Acid) (30.45 %), Octadecanoic acid (Stearic acid) (17.33 %)). These components isolated from the chloroform fraction of Adenodolichos paniculatus are used by traditional medicinal practitioners for the management of mouth and throat infections. The antibacterial activities against Streptococcus pyogenes, Staphylococcus aureus and Pseudomonas aeruginosa were evaluated using bioautography and agar-well diffusion methods. The bioautogram result showed that component A had inhibited spots against S. pyogenes (17.50 mm) and P. aeruginosa (16.00 mm), corresponding to the TLC spots with Rf values of 0.594, 0.55 and 0.26, respectively. Component B showed inhibition spots against Streptococcus pyogenes (36.50 mm), Staphylococcus aureus (16.00 mm) and Pseudomonas aeruginosa (11.00 mm), corresponding to the TLC spots with Rf values 0.891, 0.87, 0.85 and 0.25, respectively. Component C showed inhibition spots against Streptococcus pyogenes (16.50 mm), Staphylococcus aureus (15.00 mm) and Pseudomonas aeruginosa (10.50 mm), corresponding to the TLC spots Rf values of 0.938, 0.44, 0.21 and 0.90, respectively. For the agar-well diffusion method, component A at 1 mg/ml inhibited Streptococcus pyogenes, Staphylococcus aureus and Pseudomonas aeruginosa growths with zones of inhibition 23.0, 19.5 and 17.50 mm, respectively. MIC and MBC of component A were 125, 250 and 250 and 250, 500 and 500 μg/ml, respectively. Component B at 1 mg/ml inhibited Streptococcus pyogenes, Staphylococcus aureus and Pseudomonas aeruginosa growth with zones of inhibition 30.0, 28.0 and 18.5 mm, respectively. MIC and MBC of the compound B were 31, 62 and 125 and 62, 125 and 250 μg/ml, respectively. Component C at 1 mg/ml inhibited Streptococcus pyogenes, Staphylococcus aureus and Pseudomonas aeruginosa growth with zones of inhibition 24.5, 20.5 and 17.0 mm, respectively. MIC and MBC of the component C were 62, 125 and 250 and 125, 250 and 500 μg/ml, respectively. This study confirmed that bioactive compounds of A. paniculatus root have antibacterial properties and support the use of this part of the plant as a traditional remedy for mouth and throat infections possibly caused by the test bacteria.

Published: March 2021

Olax subscorpioidea (Oliv.) leaf is widely used as a traditional remedy for pain, reduction of small tumors, edema, painful swellings, and other inflammatory conditions. Its anti-inflammatory potential in experimental animals has been documented. Furthermore, an anti-inflammatory assay guided fractionation showed that the aqueous and butanol leaf fractions were the most active. This study is aimed at investigating further, the acute and sub-acute anti-inflammatory potentials of the aqueous and butanol leaf fractions in mice and rats.Carrageenan induced paw edema in rats, xylene induced ear edema in mice, and cotton pellet induced granuloma in rats were the models employed for the studies. For each of the methods, four randomly-selected groups of animals (n=5/6) were orally administered with distilled water (1 ml/kg), aqueous or butanol fraction (1,000 mg/kg) and standard drugs (acetylsalicylic acid [ASA] 300 mg/kg or dexamethasone, 1 mg/kg).The aqueous and butanol fractions each showed significant (p < 0.01) inhibition of ear swelling, the fractions also significantly (p < 0.05, p < 0.01) decreased the paw edema, and significantly (p < 0.01) inhibited the granuloma formation.The result of the study suggests that aqueous and butanol leaf fractions of Olax subscorpioidea are effective against acute and sub-acute inflammation.

Published: March 2021

BACKGROUND
Multidrug-resistant organisms (MDROs) are a public health threat. Single-centre interventions, however, are likely to fail in the long term, as patients are commonly transferred between institutions given the economic integration across borders. A transnational approach targeting larger regions is needed to plan overarching sets of interventions. Here, we aim to describe differences in diagnostic and infection prevention and control (IPC) measures in the fight against MDROs.

METHODS
In 2019, we systematically assessed diagnostic algorithms and IPC measures implemented for detection and control of MDROs at three tertiary academic care centres (Freiburg; Strasbourg; Basel). Data were collected using a standardised data collection sheet to be filled in by every centre. Uncertainties were clarified by direct contact via telephone or email with the data supplier. Internal validity was checked by at least two researchers independently filling in the survey.

RESULTS
All centres have established a primarily culture-based, rather than a nucleic acid amplification-based approach for detection of MDROs (i.e., vancomycin-resistant Enterococci [VRE], methicillin-resistant Staphylococcus aureus [MRSA], extended-spectrum beta-lactamase-producing Enterobacteriaceae [ESBL], carbapenemase-producing and carbapenem-resistant Gram-negatives [CPGN/CRGN]). IPC measures differed greatly across all centres. High-risk patients are screened for most MDROs on intensive care unit (ICU) admission in all centres; only the French centre is screening all patients admitted to the ICU for VRE, MRSA and ESBL. Patients colonised/infected by MRSA, quinolone-resistant ESBL Klebsiella spp. and CPGN/CRGN are isolated everywhere, whereas patients colonised/infected by VRE and ESBL are usually not isolated in the German centre.

CONCLUSIONS
In contrast to the French and Swiss centres, the German centre no longer uses isolation measures to control VRE and quinolone-susceptible ESBL. Overall, the French centre is more focused on intercepting MDRO transmission from outside, whereas the German and Swiss centres are more focused on intercepting endemic MDRO transmission. These findings point to important challenges regarding future attempts to standardise IPC measures across borders.

China in Latin America in the 21st century
Authors: Santoro M.
Published: March 2021

In the last two decades, China became a major economic force in Latin America, due to trade and investment, and it established strong links with the countries in the region, including a strategic partnership with Brazil. However, Chinese influence is also provoking concerns in the United States, while the latter is trying to curb Beijing’s role in Latin America. This paper analyzes China’s actions in the region and the American response, using Brazil as a case-study environment because of its importance for the Chinese foreign policy and its current president, who adopted a pro-Trump foreign policy and a rhetoric that is very critical of Beijing. The author begins by analyzing China’s strategy towards Latin America presenting a historical outlook of major events thereto, particularly underscoring both growth and diversification of the Chinese investments in the last decade. The author then proceeds to analyzing current position of the U.S. towards Chinese actions in Latin America, additionally highlighting major U.S. concerns thereto. The final part of the paper represents a case-study of Chinese policy towards Brazil and correspondent Brasília’s position on the subject concerned. It is noted that close-term prospects are complicated to draw due to the dynamic changes in the international scenario, with the deterioration of the Washington-Beijing relations, and the cross-pressures that these disputes will bring to Brazil.
Growth formula: economy of Portugal after the “Carnation Revolution”
Authors: Yakovlev P. P.
Published: March 2021

This article provides an overview of the Portuguese economy in the last quarter of the 20th and early 21st centuries. Assessing several key indicators of economic development within a historical perspective, the author highlights the most important factors that set the dynamics of national socio-economic growth. For more than four decades, since the “Carnation Revolution” (April 25, 1974), the Portuguese Republic has undergone profound changes in the economy and the socio-political sphere. In the country, there are new, as well as modernized traditional industries, a modern structure of production and consumption; GDP has increased six times, exports of goods and services have grown dramatically. In general, Portugal organically blended in the world economic system, took its rightful place in the global division of labor. One should take into account the effects of the global crisis of 2008-2009, when the Portuguese economy found itself in the epicenter of the “perfect storm” (pairing internal and external negative factors) and was pushed back in practically all key macroeconomic indicators. Despite such a system failure, in the second half of the 2010s, Portugal managed to cope with the peak of the crisis, overcame the general effects of the recession and began to show some of the highest rates of economic growth among the states of the euro zone. However, preservation of the positive economic dynamics is currently threatened by external challenges that require timely and effective response. Such challenges of global nature include the COVID-19 pandemic, the economic impact of which appeared to be a real shock for Portugal, as well as for many other countries in the world.

Secondary education has the highest share with 46.3% when educational status is examined. The most important goal of the producers in agricultural production has been to achieve the highest profit. Their most insignificant purpose is to try to set an example for the farmers around them. Farmers are aware that they need to protect nature in order to be able to farm in the future. It is seen that the protection of nature for farmers is important in terms of sustainability in agricultural production. Cooperatives should be supported in order to overcome the problems of producers who produce with small capacity in the region. The producers who have understood the importance of the environment should be given technical support and training activities should be intensified.

Published: March 2021

When it comes to blasting in soil, in general, and blasting in clay medium under water, in particular, typical parameters for destruction effect of explosion known as splashed funnel based on water depth, the depth of buried explosives in clay medium and the explosive mass. This relation is multidimensional and multivariable. Using traditional integation addressing empirical data still has limits in presenting a general law in entire domain relating to such relation. Therefore, based on the empirical results collected from the previuos study, this paper will concentrate to make a machine learning algorithm building a regression model, finding the general empirical law about the dependence relation of the radius of splashed funnel in clay medium under water, based on splashed funnel and the water depth, the depth of buried explosives in clay medium and the radius of explosives charges. The efficiency of the model will be evaluated with correlation coefficent R2 between the calculated values of funnels and its real values in experiments. Consequently, the model reached high accuracies which can be applicable in the reality.

Due to the effects of dynamic pressure, the stress distribution of rock mass is very complex. The reason for this could be a risk of stability loss for an auxiliary tunnel system constructed within the study area. In this article by using Flac3D software the author simulated two adjacent working faces with the thickness of 5 m natural coal pillar. Three factors: the upper working face excavation process, auxiliary tunnel mining process, and the location of lower working face, affected by deformation, stress distribution, safety of lower floor area and surrounding rock mass of tunnel. The research results show that during the excavation, the mechanical behavior of the rock mass surrounding the auxiliary tunnel showed displacements, volatility, and phase characteristic. The displacement on the auxiliary tunnel boundary in both excavation and working face cases showed that the roof and the left side wall displacement was greater than the right side wall and the bottom. Therefore, the distance between the auxiliary tunnel and the empty mining space needs to be computed to meet technical and economic requirements.

O presente artigo apresenta uma reflexão sobre os reflexos da pandemia da Covid-19 para a condição de vida da população vulnerável do país. Apresenta também uma aproximação entre a noção sobre o direito à cidade e a resposta construída por moradores de Paraisópolis, na cidade de São Paulo. O direito à cidade remete ao processo de privatização do espaço e do bem público das cidades, um efeito da contradição da nossa sociedade e da financeirização do capital. A experiência vivida pelo moradores da comunidade de Paraisópolis revela a construção de alternativas à crise pela própria população, as características do território, bem como a possibilidade de construção na cidade urbana de bens comuns, de comunalidades, conforme a noção desenvolvida por Harvey. Além disso, aponta a urgência das demandas sociais que devem ser destaques das ações articuladas do poder público brasileiro. Desta forma, o direito à cidade ode revelar as urgências e as demandas coletivas de grupos vulnerabilizados residentes em diferentes territórios, especialmente de diferentes centros urbanos.

O ESTADO NEOLIBERAL E A PROPOSTA DE EMPODERAMENTO FEMININO
Authors: Elita de Sousa Silva Débora
Published: March 2021

Nesta pesquisa nos propomos a analisar as teorias que inspiram o modelo estatal neoliberal e suas implicações sobre a perspectiva de empoderamento feminino. Neste sentido, foi necessária a apreensão das origens e das principais teorias que fundamentam o pensamento neoliberal; das implicações que o relacionam com a perspectiva de empoderamento feminino; e das limitações que caracterizam o modelo de desenvolvimento social neoliberal e a estratégia de empoderamento feminino. O percurso teórico-analítico foi traçado por meio de pesquisa bibliográfica das principais referências que fomentam o neoliberalismo, bem como dos que defendem o empoderamento como causa última pela qual a humanidade precisa lutar. Para fazer a problematização das limitações teóricas e político-práticas recorremos às referências marxistas materialistas que versam sobre o projeto neoliberal e os desafios ao feminismo marxista na atualidade. Concluímos que o neoliberalismo se apresenta como defensor da liberdade dos indivíduos, mas a concebe de forma restrita aos interesses de expansão do capital. Adentrando todas as esferas da vida social, o neoliberalismo apropria-se das pautas feministas e as converte em meios de valorização do capital via mercado. Contudo, esses processos não ocorrem de forma passiva. A degradação da vida pode suscitar a resistência e a transformação radical da sociedade. A luta contra o projeto neoliberal deve ser traçada por todos os trabalhadores e trabalhadoras, feministas, anticapitalistas, antirracistas, anti-lgbtfóbicas e ecossocialistas, rumo à plena expansão e emancipação do gênero humano.

DIGITAL CULTURE AS A FRAMEWORK OF CIVIC ACTIVISM
Authors: Petković Jelena , Božilović Jelena
Published: March 2021

The basic assumption of the paper is that digital culture, regardless of how much it is based on technological progress, is not determined by it, but necessarily arises from the values, ways of thinking and acting that are grounded in that technology and by it, and that have enabled its development. Thereby, the introduction will be dedicated to a critical deliberation on digital culture as a platform for the (de)construction of individual and collective identities, analysing its participative, mobilizational and subversive potential in the context of agitation and realization of social and cultural changes, civil rights and freedoms. The main purpose of this paper is to explain from the sociological point of view how digital culture has determined, shaped and transformed the paths of civic activism, especially in the last few years in Serbia. By using secondary sources of data, the paper will analyse to which extent the Internet and social networks represent important instruments of communication and mobilization of citizens for protesting and organization of various political events. A special critical emphasis will be directed towards the effects, advantages and limitations (activation or passivization) of civic engagement in the context of digital culture. The application of the comparative method in the final part of the paper will point out how much Serbian civic activism follows or differs from European movements that also rely primarily on the Internet and social networks as a medium for mobilization.

A Qualitative Exploration of Emerging Adults’ and Parents’ Perspectives on Communicating Adulthood Status
Authors: Jablonski Jessica , Martino Sara
Published: March 2021

In this study the authors examine parent - child communication in Emerging Adulthood. Thirty - seven college students and one or both of their parents completed written questionnaires assessing whether the parent had verbally communicated or did some action to acknowledge the Emerging Adult’s maturity. Communication about changes in the parent - child relationship, as well as the Emerging Adult’s decision - making abilities, obligations to the family, and financial responsibilities were also assessed. The responses to the open ended questions were qualitatively analyzed using grounded theory. The findings indicated that the Emerging Adults’ and parents’ responses were very similar, and the overwhelming majority reported that there had indeed been an acknowledgment from the parents to indicate Emerging Adulthood status, although this was not always verbally communicated; sometimes it was indicated through the parents’ behavior.

In schools where curricular constraints and testing pressures narrow the ways in which students can take up identities as writers, longterm enrichment programs offer opportunities for the meaningful design of compositions. This paper, which presents the work of four elementary student participants in a writing workshop, shows how qualitative inquiry -- in particular critical multimodal analysis -- can enable a teacher researcher to see, interpret, and explain what might be going on in the writings and drawings of students, and how these illuminations help establish and expand the identities of students as writers. I focus especially on the work of one student over three years, and share the methodological procedures I drew upon in order to generate claims about his writing identity.

The aim of this study is to identify the impact of generational differences on employee preferences for engagement - enablers and drivers at feroze1888 mills ltd. To conduct this research, Employee Engagement Drivers have been identified through the research paper named as ‘The Drivers of Employee Engagement- a diagnostic model' which was presented by Institute of Employment Studies in 2003, while the Employee Engagement Enablers have been extracted from the research paper ‘Engaging for Success- Enhancing performance through employee engagement’ published in 2009 by MacLeod and Clarke. The identified variables in terms of Enablers and Drivers have then been evaluated with respect to preferences of three generations for them which includes Baby Boomers, Gen X and Gen Y. Stratified Random Sampling has been used for this research resulting in a total sample size of 208 respondents comprising of 3 strata groups based on the 3 generations. For data Integration and analysis, one-way ANOVA has been used to find out the results in categorical form for the purpose of creating a comparison between the three groups. Having some of its hypothesis rejected while majority getting excepted, the research has concluded that ‘yes there do exist some difference amongst the 3 generations in their preferences for the Enablers and Drivers’. This research can be useful for organizations who consider the Engagement of each of their employees equally important regardless of the age bracket to which they belong. This research can provide them an insight about which areas of Employee Engagement are to be kept in focus to engage their young, middle aged and senior employees.
Education, the Dream that is Materializing
Authors: Annamalai Visalaakshi
Published: March 2021

The right to education is a fundamental aspect of human rights. It shapes life for a better tomorrow with a chance of an increase in better employment opportunities. It not only instills hope for a brighter future but also leads to the realization of other rights.1 Progress in human life is impossible without education, but despite this fact, refugees struggle to have access to education. Importance of the right to education increases when it comes to refugees because of its ability to uplift the standard of living. This paper will look at the right to education as a concept and the meaning attributed to the word education. It will shed light on the nature of the right; whether it is a socio-economic and cultural right or a political right. The paper will further examine international instruments which recognize the right to education in emergencies and comprehend how it has been applied to the case of refugees. It points out two positive examples where access to education has been provided by community-based organizations in collaboration with NGOs, governments, and other organizations. The paper acknowledges the barriers to higher education but is not ignorant of the fact that there is progress today as compared to forty years ago. The paper concludes that despite the conscious movement of the international community towards the right to education of the refugees, there is much that has to be done for the complete realization of this right.
Gurkha's Quest for Justice: Possible Remedies for Gurkhas under International Human Rights System
Authors: Sangroula Geeta Pathak
Published: March 2021

There is a 205-year long history of Gurkha’s entanglement with the British. In 1816, the British East India Company defeated Nepal in the Anglo-Nepalese war. Dominant narratives of this history suggests that the British were impressed by the war-fighting capabilities and loyalty of the Gurkhas, and recruited them- not as mercenaries but part of their army- to fight in the World Wars, to maintain imperial administration in British India, Burma, Malaya, Singapore, and Hong Kong. After the 1947 Tripartite Agreement between India, Nepal, and Britain, Gurkha soldiers were recruited annually in both British and Indian armies. For decades, the Gurkhas have carried out a movement seeking equal pay and pension in comparison to their British counterpart. After a long struggle, their movement reached the European Court of Human Rights wherein the Court did not find a violation of the European Convention regarding the differential treatment of Gurkha soldiers. The paper, briefly subscribes to the available literatures about the magnitude of problems and the status of Nepali Gurkhas in the British Army, including an overview of the commitments and obligation of United Kingdom towards human rights. The paper fills the scholarly gap by taking international human rights as an analytical framework in approaching the Gurkhas’ issue. In making a case for possible remedies, Gurkhas as ‘rightsholders’ is proposed as a suitable frame. It concludes with recommendations, grounded in international human rights law, as a possible remedial mechanism for the Gurkhas — in their quest of justice.

"We never got equal terms and pay, and we are not even bothered about that. What we are seeking is justice for our pensions, getting equal to what the British get, according to the service rendered." (Retired major Tikendra Dal Dewan)

Introduction: Flexible bronchoscopic intubation (FBI) is an important technique in managing an anticipated difficult airway, yet it is rarely performed and has a steep learning curve. We aim to evaluate if the integration of virtual reality gaming application into routine FBI training for emergency department doctors would be more effective than traditional teaching methods. Methods: We conducted a randomised controlled trial to compare self-directed learning using the mobile application, Airway Ex* in the intervention group versus the control group without use of the mobile application. All participants underwent conventional didactic teaching and low-fidelity simulation with trainer’s demonstration and hands-on practice on a manikin for FBI. Participants randomised to the intervention arm received an additional 30 minutes of self-directed learning using Airway Ex, preloaded on electronic devices while the control arm did not. The primary outcome was time taken to successful intubation. Results: Forty-five physicians (20 junior and 25 senior physicians) were enrolled, with male predominance (57.8%, 26/45). There was no difference in time taken to successful intubation (median 48 seconds [interquartile range, IQR 41–69] versus 44 seconds [IQR 37–60], P=0.23) between the control and intervention groups, respectively. However, the intervention group received better ratings (median 4 [IQR 4–5]) for the quality of scope manipulation skills compared to control (median 4 [IQR 3–4], adjusted P=0.03). This difference remains significant among junior physicians in stratified analysis. Conclusion: Incorporating virtual reality with traditional teaching methods allows learners to be trained on FBI safely without compromising patient care. Junior physicians appear to benefit more compared to senior physicians. Keywords: Airway management, emergency medicine, intubation, simulation education, virtual reality

Background: Coronary chronic total occlusions (CTOs) represent the most technically challenging lesion subset that interventional cardiologists face. CTOs are identified in up to one third of patients referred for coronary angiography and remain seriously undertreated with percutaneous techniques. The complexity of these procedures and the suboptimal success rates over a long period of time, along with the perception that CTOs are lesions with limited scope for recanalization, account for the underutilization of CTO Percutaneous Coronary Intervention (PCI).

Purpose: To study the impact of social support (indices of close contacts and social netwotks) on the risk of arterial hypertension (AH) in an open population of 25-64 years in Novosibirsk. Methods: A random representative sample of the population of both sexes of 25-64 years old in Novosibirsk in 1994 (men: n = 657 44.3 ± 0.4 years response - 82.1% women: n = 689 45.4 ± 0.4 years response - 72.5%). The screening survey program included: registration of socio-demographic data determination of the level of social support (ICC - index of close contacts SNI - index of social networks). The period of prospective follow-up of participants was 16 years. Results: In the open population of 25-64 years low rates of ICC and SNI were in 62% and 43.5% of men and 56.8% and 33.9% of women. During the first 5 years the risk of hypertension in men and women with a low ICC was the same in men HR = 2.063 (95% CI 1.019-5.213 p <0.05) and women with HR = 2.009 (95% CI 1.025- 3.938 p <0.05). The increase in the risk of AH in persons with low SNI over 5 years was higher in men in 5.9 (95% CI 1.278-8.361 p <0.05) times 10 years later the risk of developing AH in women 25-64 was 1.884 (95% CI 1.09-3.255 p <0.05). The risk of hypertension was highest among men: never married divorced and widowed with low ICC and SNI. Among women at risk were widowed women with low ICC as well as women with primary education with low ICC and SNI. Conclusion: Low level of social support increased the risk of AH in men and women.
Relationship between perceived self-efficacy and teaching practice performance among pre-service basic science teachers in colleges of education, Delta State, Nigeria
Authors: Ewesor Stella , Urevbu Andrew
Published: March 2021

The study examined the relationship between perceived self-efficacy of pre-service basic science teachers and teaching practice performance in colleges of education in Delta State, Nigeria. One hundred and twelve (112) pre-service basic science teachers were selected from two colleges of education in Delta State. Forty-six (46) from College of Education l (COEI) while sixty-six (66) from College of Education II (COEII). The study tested three hypotheses derived from the three research questions. The independent variable was perceived self-efficacy of the pre-service basic science teachers, the dependant variable was teaching practice while the moderating variables were two colleges of education of the pre-service science teachers. The instruments used were “Teaching Practice Assessment Score Instrument (TPASI)” and the “Pre-Service Science Teachers Perceived Self Efficacy (PSTPSE)” with thirty (30) questions. Person correlation was used to test the hypotheses. The results showed that the three null hypotheses were accepted. The hypothesis one is accepted because there was no significant relationship found to exist between the pre-service basic science teachers perceived self-efficacy and their teaching practice assessment scores. Also, no significant difference was found between COEI and COEII pre-service basic science teachers‟ perceived self-efficacy scores and their performance in teaching practice. Finally, for all the pre-service basic science teachers irrespective of their subject combination, there was no relationship between their perceived self-efficacy and the teaching practice assessment. Consequently, it was recommended that there should be a reform in pre-service teacher education programmes in all our teachers training institutions; it can help to develop and improve teacher education programmes and pre-service teaching practice; this reform should aim at strengthening both content and pedagogical knowledge of pre-service teachers.
