Essays on commodities and economic uncertainty
Authors:   , Pinto Victor Henrique Lana
Published: October 2024

Commodities play a pivotal role in global trade, encompassing raw materials and agricultural products vital for economic growth and stability. This dissertation investigates the intricate relationship between commodities and economic uncertainty, exploring how these factors interact and influence economic dynamics. Drawing on a multidisciplinary framework, this study encompasses two independent papers that collectively contribute to the understanding of commodity markets and economic uncertainty. The first paper examines the impact of commodity exports on institutional quality across a range of developing and advanced economies from 1997 to 2022. Using panel data analysis and China's accession to the World Trade Organization as a natural experiment, the study reveals a significant negative causal relationship between commodity exports and institutional development. This finding underscores the adverse effect of commodity wealth on institutional effectiveness, highlighting the complexities of economic governance in resource-dependent nations. In the second paper, the focus shifts to the interactions between commodity futures (specifically live cattle and soybeans) and the stock market in Brazil from January 2014 to July 2023. Through time-series analysis, we investigate the influence of policy changes on commodity-stock dynamic correlations. We do not observe an economically significant effect of economic uncertainty originated in Brazil and abroad on the time-varying interactions between commodity and stock markets in Brazil. Overall, this dissertation contributes valuable insights into the nexus of commodities and economic uncertainty, shedding light on their complex interplay and implications for economic stability. By elucidating these relationships, this study offers practical guidance for policymakers, investors, and stakeholders, facilitating informed decision-making and enhancing risk management practices in an increasingly volatile global economy. Keywords: Institutions. Agricultural Exports. Commodity Futures. Uncertainty.

The effects of Nano encapsulated phytogenes on the histology of the liver, intestine, histometry and protein signature of African catfish Clarias gariepinus post fingerlings exposed to pathogenic stressor was assessed in this study. Three hundred fish with the average weight of 26.00 ±0.05g were fed with Nano encapsulated diets for 56 days. The phytogenes used were 0.5g of Telfairia occidentalis (Ugwu leaf), Zingiber officinale (Ginger leaf), Moringa oleifer (Moringa leaf) and Ocimum gratissimum (Scent leaf) /100g. After 56 days of feeding trial the fish were challenged with a bacteria strain Pseudomonas fluorescence for 14 days. The liver, intestine and muscle of the challenged fish were assessed for histopathological and SDS PAGE analyses. Histological analyses of the liver and intestine revealed less histopathological alterations in the treatments fed with Nano encapsulated diets to those fed with control positive diets. SDS PAGE analyses of the protein also revealed disintegration in the number of bands and molecular weight concentration to those fed in control positive diets. There were no significant difference (P>0.05) in the liver of the treatments fed with Nano encapsulated diets to those fed with control positive diets. Significant difference (P<.0.05) were observed in the intestine, histometry of fish fed with Nano encapsulated diets to those fed with control positive diets. There were also significant difference (P<0.05) in the protein signature of the treatments fed with Nano encapsulated diets to those fed with control positive diets. This study showed that phyto-additives diets is a potential treatments against bacterial infection in the farming of aquatic organism Clarias gariepinus.

Authors:   International PhD Program in Cell Therapy and Regeneration Medicine, College of Medicine, Taipei Medical University, Taipei 11031, Taiwan, Anurogo Dito
Published: October 2024

The combination of nanotechnology and CAR T-cell therapeutics heralds a paradigm shift in the management of ovarian cancer, a disease characterized by substantial obstacles such as antigenic heterogeneity, an immunosuppressive tumor microenvironment, and physical barriers to treatment efficacy. This paper examines these obstacles critically and proposes innovative nano-engineered solutions, such as the development of nano-CAR T cells and nanoparticle-mediated delivery of CAR genes and immunomodulatory agents, as strategic approaches to improve CAR T-cell delivery, survival, and function within the hostile tumor microenvironment. The convergence of these two disciplines represents a promising strategy for overcoming these obstacles and optimizing the therapeutic potential of CAR T cells in solid malignancies. To translate this promising approach into a viable clinical reality in the fight against ovarian cancer, however, additional scientific research and rigorous clinical trials are required to ensure safety, optimize the design, and establish standardized production and application protocols.

Published: October 2024

Background: Education is a vital component of both societal and individual growth. To create effective learning environments, it is essential to understand the factors that influence student achievement. However, the application of machine learning algorithms can drive positive change, providing higher education institutions with effective solutions to their challenges. Aim: This research develops a predictive model to identify and analyze the factors affecting student academic performance, aiming to provide institutional administrators and lecturers with a better understanding of the key factors impacting student success. Method: A comprehensive dataset was collected from undergraduate students at Modibbo Adama University (MAU), Yola, comprising student-related, home-related, lecturer-related, and institution-related factors. Model development was carried out using Python in Google Colab, a cloud-based Jupyter notebook environment. Classification algorithms such as K-Nearest Neighbors (KNN), Decision Tree (DT), Gradient Boosting Method (GBM), and Random Forest (RF) were applied to predict student academic performance. Four evaluation metrics namely; accuracy, precision, recall, and f1-score were used to analyze the models. Results: The Random Forest model outperformed the other machine learning models, achieving an overall accuracy of 95%. For predicting low-performing students, the model achieved a precision of 0.9677, recall of 0.9474, and f1-score of 0.9574. For high-performing students, the precision was 0.9324, recall was 0.9583, and f1-score was 0.9452. These strong performance metrics across both low and high performing student groups demonstrate the effectiveness of the Random Forest model in accurately predicting student academic performance based on the factors considered in the study. Feature importance analysis identified lecture attendance, sponsor support, quality of facilities, and lecturer clarification as the most influential factors on student performance. Other features, such as accommodation, employment status, and program preference, were found to have a low impact. These findings emphasize the importance of considering a comprehensive set of student, lecturer, institution, and home-related factors to sustain a conducive learning environment and enhance educational practices.

Authors: Omonya Kenneth Seth , Otiso W. Nyachoti , Mwirigi Charles
Published: October 2024

The primary objective of probation supervision is to ensure compliance with probation conditions, improve public safety, and rehabilitate and reintegrate offenders back into a pro-legal and social lifestyle. However, statistics in Kenya point to consistently high rates of recidivism in the past two decades. Despite this, limited information exists on the effect of juvenile supervision practices on recidivism in the country. This study aimed to evaluate the existing juvenile probation supervision practices and their outcomes in Nairobi County, Kenya. The study sampled 226 respondents comprising juvenile probationers and probation practitioners. Using a concurrent triangulation mixed-method approach, three probation supervision practices, namely, frequency and mode of supervision, supervision skills and workload, were examined. The outcomes for each of the three practices were varied, with frequency and mode of supervision having a reducing effect on recidivism but not significant. Supervision skills and probation officers’ workload significantly impacted recidivism. Collectively, the centrality of the existing probation supervision practices in curtailing juvenile reoffending behavior was evidenced. However, a number of challenges, including limited specialized training and mentorship in juvenile matters, resource constraints and overwhelming workloads, limited optimal outcomes. The study recommends consistent juvenile-focused training on supervision skills, clear guidelines to sustain manageable caseloads, and leveraging technology for administrative tasks and remote supervision.
The Suitability of the Mandate Used by the United Nations Humanitarian Military Intervention in North Kivu Province, Eastern Democratic Republic of Congo, 2004-2022
Authors: Oduor Oduol Joseph , Oduor Otieno Isaiah
Published: October 2024

North Kivu is one of the provinces in Eastern Democratic Republic of the Congo (DRC) where conflict seems to defy the multiple interventions by a number of national, regional and international organizations. It hosts several United Nations Humanitarian Military Intervention (UNHMI) bases and has shown a humanitarian crisis resulting from the conflict in Eastern DRC including hostilities by the armed groups. This study interrogated the suitability of the mandate used by the UNHMI through the United Nations Organization Stabilization Mission in the Democratic Republic of the Congo (MONUSCO) between 2004 and 2022. This study was informed by two complementary theories namely; Realism and New Institutionalism. Realism argued that that humanitarian military intervention by the UN in Eastern DRC was motivated by the need to promote the geopolitical interests of powerful states. New Institutionalism on the other hand contended that North Kivu province was characterized by weak institutions and there was lack of trust between the different actors. This study took the form of an exploratory research design employing the use of both primary and secondary sources. Purposive and snow ball sampling techniques were used to select 99 respondents who included 19 representatives from international humanitarian organizations in North Kivu, 20 representatives from the civil society, 10 government officials, 15 experts in conflict management, 15 security specialists, and 20 Congolese nationals. Questionnaires and interview schedules were the main research instruments. The study concluded that in as much as the UNHMI was suitable in the context of conflict management, the operation faced a number of setbacks. The study recommended that the government of DRC, taking advantage of the suitability of the Mandate of UNHMI, should cooperate with and provide more support to MONUSCO in addressing the conflict.

Published: October 2024

The objective was to evaluate soil density (Ds) and penetration resistance (RP) in an experimental area with forage palm management. The study was conducted in an experimental area belonging to the Federal University of Alagoas - Arapiraca Campus. To determine the Ds, undeformed samples were collected at three points within the plot, each point with three different depths (0-10; 10-20 and 20-30 cm). To determine the PR, the impact penetrometer was used at depths of 0-60 cm. For comparison purposes, samples were collected in a native forest area. The data were submitted to analysis through the statistical program R and Tukey test at 1 and 5% probability. Ds ranged from 1.59 to 1.63 g cm-3, not differing significantly. The lowest densities were obtained in the surface layer, influenced by the contribution of organic matter and greater presence of roots. In all depths evaluated, the Ds values were lower for the native forest area. In relation to PR, the values gradually increased up to the first 20 cm of depth for most treatments, reflecting the influence that the non-soil revolution causes in the most superficial layers. Therefore, Ds did not differ significantly. The 0-10 cm layer showed the lowest Ds values. The native forest showed the lowest Ds values at all depths when compared to the managed area. PR gradually increased to the first 20 cm of depth for most of the treatments analyzed.

A cultura da soja (Glycine max L.) enfrenta desafios em regiões com estresses abióticos, como altas temperaturas, luminosidade intensa e restrição hídrica, o que pode afetar as moléculas de clorofila. Neste contexto, a tecnologia de filme de partículas de cálcio tem se destacado como uma alternativa de mitigação de estresses abióticos. Com isso, objetivou-se avaliar os teores de clorofila em uma cultivar de soja não adaptada a região Nordeste do Brasil sob condições estressantes. O experimento foi conduzido em estufa agrícola sob condições de altas temperaturas e luminosidade oriundas do Nordeste brasileiro, sob três regimes hídricos (80, 40 e 20% da capacidade de campo do solo) e aplicação foliar de filme de partículas de óxido de cálcio na proporção de 6% e a testemunha livre de aplicação do mesmo. Os teores de clorofila a e b foram avaliados por meio de índices de clorofila Falker em folhas expostas à luz solar durante a fase vegetativa (V8). Os resultados demonstram que o filme de partícula contribuiu para a preservação/aumento dos teores de clorofila nas plantas. Concluiu-se o uso de filme de partícula de cálcio apresenta potencial para melhorar a adaptação de plantas de soja às condições adversas encontradas na região Nordeste do Brasil.
Straight enough: Deriving imprecise interpretations of maximum standard absolute adjectives

While maximum standard absolute adjectives (such as straight) typically have a precise meaning (e.g., ‘perfectly straight’), they are also regularly used imprecisely (e.g., to mean ‘straight enough’). The current study investigates how contextual expectations of precision and a visual referent’s conceptual distance from an ideal maximum standard influence the processing effort of precise and imprecise interpretations of these adjectives. In three experiments, we showed native speakers of English images depicting objects that could be referred to precisely or imprecisely via an absolute adjective and asked them to select the image that best matched the written sentence (Experiments 1 and 2) or to read sentences containing maximum standard absolute adjectives (Experiment 3). Experiment 1 presented no discourse context, and participants accepted, on average, only a small degree of imprecision; and when they did, they took longer, relative to cases in which the same adjectives were used precisely, which is in line with existing empirical findings. Experiment 2 contrasted two kinds of discourse contexts (raising high or low expectations of precision) before the presentation of the test sentences. When expectations of precision were high, participants tolerated only a small degree of imprecision, and when they did, it came at a cost, as in Experiment 1. When expectations of precision were low, much larger degrees of imprecision were tolerated but, critically, participants were still, overall, faster to reach precise, relative to imprecise, interpretations in supporting contexts, suggesting that accessing the precise meaning is less effortful. Experiment 3 supported these findings by showing how the cost of understanding imprecision is also present in a self-paced reading task. Our results lend support to the view that maximum standards are part of the encoded meaning of these adjectives.
Watch your tune! On the role of intonation for scalar diversity
Authors: Ronai Eszter , Göbel Alexander
Published: October 2024

Recent research has highlighted that lexical scales vary in their likelihood of giving rise to a scalar inference—a finding labeled scalar diversity. The current paper examines the role of intonation for this phenomenon, which has thus far primarily been studied using written materials. A specific focus in this regard was on the so-called rise-fall-rise contour, which has been argued to (i) convey uncertainty, which could have an influence on scalar inference calculation, and (ii) be sensitive to properties of lexical scales, which could interact with factors driving scalar diversity. Experiment 1 combined production with an inference task to assess the likelihood of different intonational contours, as well as how a given contour affects scalar inference rates. Production of the rise-fall-rise varied across lexical scales, as expected, and led to an increase in scalar inference derivation relative to a fall. The latter finding was further confirmed in Experiment 2, which explicitly manipulated intonational contours in the inference task. The results, thus, show the importance of taking intonation into account when studying scalar diversity and scalar inference more generally, and they also have implications for theories of the rise-fall-rise contour. Additionally, the experiments revealed a contour that is prosodically similar to the so-called Contradiction Contour, but appears to serve a different pragmatic function.

Introduction

Although reliable new evidence has identified several advantages of resistance training (ResEx) on cardiac performance, the role of this type of training in protecting the myocardium against ischemia-reperfusion (IR) injury is not clear. The aim of this study was to investigate the effect of resistance training on cardioprotection versus IR-induced injury.

Material and methods

60-day-old male Wistar rats (n = 24), weighing 220–240 g, were divided into four groups: Resistance Training (ResEx), Isoproterenol (ISO), Resistance Training + Isoproterenol (ResEx + ISO), and control groups (n = 6 for each). Trained rats performed exercise in a squat-training apparatus (8–12 repetitions/set, eight sets/day, and 5 days/week for 8 weeks). After the last training session, all the rats were sacrificed with ketamine xylazine injection. The heart of rats was removed from the body and washed quickly with cold PBS, immediately put in liquid nitrogen, and stored at –70°C. Superoxide dismutase (SOD), glutathione peroxidase (GPX), and catalase (CAT) activity was measured.

Results

Induction of ischemia decreased SOD and CAT activity but had no effect on the activity of GPX. Eight weeks of resistance training significantly increased activity of SOD and CAT compared to the ISO group.

Conclusions

The results of the present research demonstrated that ischemia induced by isoproterenol injection during 8 weeks of resistance training did not lead to a decrease in SOD activity and prevented the reduction of CAT activity.

Wstęp

Rak podstawnokomórkowy jest najczęstszym nowotworem złośliwym skóry, stanowiącym 90% przypadków. Wśród najistotniejszych czynników ryzyka wyróżnia się wiek, płeć męską, fototyp skóry I i II, częstą ekspozycję na słońce, oparzenia słoneczne oraz dodatni wywiad rodzinny w kierunku innych nowotworów skóry. Ponad 75% raków podstawnokomórkowych występuje w okolicy głowy i szyi. Około 20% pojawia się w okolicy oczodołowej.

Opis przypadku

76-letni mężczyzna został skierowany do Kliniki Okulistycznej z powodu keratopatii oka prawego na skutek pooperacyjnej niedomykalności powiek. 11 lat wcześniej pacjent przeszedł operację wycięcia raka podstawnokomórkowego prawej okolicy skroniowej, w wyniku której wystąpiła niedomykalność powiek. W badaniu przedniego odcinka oka prawego stwierdzono zrosty spojówkowo-powiekowe, niedomykalność powiek, ograniczoną ruchomość gałki ocznej oraz keratopatię. Pacjenta skierowano do operacji plastyki powiek i worka spojówkowego. Wykonano zabieg, podczas którego uwolniono zrosty spojówkowo-powiekowe, przeprowadzono rekonstrukcję worka spojówkowego z wykorzystaniem przeszczepu błony śluzowej dolnej wargi oraz plastykę powieki górnej z przeszczepem skóry z tejże powieki. Zabieg przeprowadzono bez powikłań. Przeszczep błony śluzowej przyjął się prawidłowo oraz uzyskano domykalność powiek. Pacjent był ściśle kontrolowany w Klinice przez 8 lat po wykonaniu zabiegu, stan miejscowy oka prawego pozostawał stabilny.

Wnioski

Rekonstrukcja powiek i worka spojówkowego za pomocą przeszczepów błony śluzowej warg i skóry zapewnia skuteczną metodę leczenia niedomykalności powiek i zrostów spojówkowo-powiekowych, zachowując funkcję powiek i chroniąc powierzchnię oka.
