Paradigma Keilmuan Dalam Pemikiran Pendidikan Islam Kontemporer Tantangan Dan Prospek
Authors: Muhammad AlFarobi  , Rahmat Syukur  , Latifah Addiba  , Dewi Maya Sari
Published: August 2022

The development of creative and dynamic intellectual insights in light and integrated with Islam must be accelerated immediately. The old grudges that continue to be perpetuated and the culture's blind rejection of the West are not wise attitudes. This will only backfire on the intellectual development of Islam. This is where the "mental attitudes" of Muslim intellectuals need to be reviewed and reorganized. This attitude can be said to be quite moderate and quite acceptable among Muslims. Meanwhile, the main solution proposed by Tibi is secularization, which is the industrialization of a society which means the functional diffrensiation of its social structure and religious system. This solution seems to only open a front that confronts muslims in general. Secularity is not a realistic option when offered in Islam, so there are bound to be many challenges to it. Although Tibi is a reliable Muslim intellectual, accurate in photographing the problems faced by the world of Islamic education in general, but for solutions more colored by his daily religious attitudes, namely a Muslim who does not obey his religion.

Fourth-Track Diplomacy: Its Time Has Come
Authors: Lea Suzanne Goodney , Rahman Eirliani Abdul
Published: August 2022

The Covid-19 pandemic highlights both the challenges to and opportunities for a reimagination of diplomacy and, by extension, democracy. Traditional views of diplomacy assert that each nation should negotiate from a ‘my country first’ perspective. But the modern social problems we face internationally, with Covid-19 being arguably a ‘dry run’ for more global management of climate change, are characterised by a need for collaboration rather than for competition. A collaborative approach would likely help to ensure that more resources reached the poorest parts of the world. We contend that a new form of diplomacy is needed. Second-track diplomacy emphasised the engagement of non-state actors, and third track combined that with traditional diplomacy, but we argue that a fourth track is now both urgently needed and quite viable. This fourth track could engage citizens in diplomacy by using dialogue and digital technologies. A range of dialogic techniques could be leveraged to facilitate the incorporation of a much broader array of voices into the public sphere, infusing more diverse and outside-the-box perspectives into the creation of policies that directly affect citizens and their communities. Such engagement could also be global, connecting people from various countries with their counterparts around the world to explore how nations might work with one another to solve global and regional problems. One nation could help another to solve even a local problem. A massive disruption to routinised lives across the planet provides an unprecedented opportunity to create new ways to meaningfully include a much wider range of voices and perspectives within the way the People – of the global citizenry – do business.
Dialogue and Peacebuilding in Colombia: A Dialogic and a Transformative Relationship
Authors: Olarte Delgado Angela Marcela
Published: August 2022

This article analyses different initiatives that have emerged from the top-down and everyday bottom-up peace approach after the peace agreement in Colombia and have led to establishing dialogues among different actors to contribute to the peacebuilding process. Three years ago, Colombia signed a peace agreement with the largest guerrilla group in Latin America. After this signature, the big challenge has been the implementation of the deal in the most conflict-affected territories, characterised by poverty, high rates of violence, unemployment, etc. Despite the pitfalls in building positive peace, many communities have started generating spaces by themselves and have created initiatives of peacebuilding through nonviolent actions, the acceptance of differences, active participation and empowerment and the acknowledgement that dialogue is the only way to achieve cooperation and to rebuild another story rather than conflict. This paper seeks to examine the different characteristics that have shaped dialogue-based practices when they are produced with a top-down and a bottom-up approach of peacebuilding. To do this, it is necessary to identify the parties participating in these encounters, their motivations, conditions that have allowed parties to establish a dialogue, and the results. This paper notes that in a post-conflict society, dialogues coming from the top-down will take longer in accomplishing positive peace, rather than the dialogues that have emerged from the bottom up which may be the engine to social mobilisations and the way to capitalise on social skills in achieving justice, truth, and reconciliation.
Teaching Through Reasoning with Sudoku Puzzles: Effects on Pupils’ Mathematical Achievement and Reasoning Performance
Authors: Jinon Dr. Stephen Raymund T.
Published: August 2022

This quasi-experimental study was conducted to find out the reasoning performance and mathematical achievement of pupils taught through two teaching strategiestraditional and teaching through Reasoning with Sudoku puzzles. The participants in the study were the 62 Grade 5 pupils of the a selected Laboratory School in Iloilo. The pupils were randomly chosen and match-paired on the basis of their pretest scores in the researcher-made mathematical achievement test. Thirty-one pupils from each section were given the interventions after the match pairing. The data-gathering instruments were the validated and reliability-tested researchermade mathematical achievement test and adapted reasoning performance test. The 60-item mathematical achievement test comprised 50 multiple choice items and 10 items on problem solving were based on topics about fractions, decimals, percents, ratio, and proportion. On the other hand, the reasoning performance test measured the pupils’ performance in verbal, numerical and abstract reasoning. The mean was used to determine the pupils’ level of mathematical achievement and reasoning performance, coupled with the use of standard deviation in determining the pupils’ homogeneity or heterogeneity in their scores. The inferential statistics utilized were the paired sample t-test to test the difference in the pretest and posttest scores of the pupils in both tests and the t-test for the independent samples to test the difference between the mean gain of the two groups in their mathematical achievement as well as reasoning performance scores. Statistical computation and processing were done through the Statistical Package for the Social Sciences (SPSS) software version 17. The 0.05 level of significance for two-tailed test was used for the inferential test. Results revealed that before the intervention the two groups were on equal level in their mathematical achievement and reasoning performance and showed homogeneity in their scores. Also, before the intervention, the pupils were hesitant in the use of Sudoku puzzles and in participating in the classroom because it was their first time to encounter the strategy. After the 7-week intervention the result showed that teaching through reasoning with Sudoku puzzles enhanced the pupils’ mathematics achievement and reasoning performance, making higher marks than those taught with the traditional strategy, where reasoning was not the main focus of the teaching process. The mean gain scores of the Sudoku group were higher than the mean gain scores of the non-Sudoku group; this implies that the strategy as well as Sudoku helped the pupils in the process of learning If pupils were given the chance to practice their reasoning skills, they could have high achievement and could improve their reasoning performance.

Cross-Border Impact Assessment for EU’s Border Regions

Within the European Union (EU), border regions represent 40% of its territory, and they are home to a third of the EU’s population. The European Commission refers to border regions as ‘Living labs of European Integration’, where both the effects of free movement and remaining obstacles to integration are most visible. These are largely of legal or administrative nature, caused on both national and EU level. As acknowledged in the Commission’s report on Better Regulation, the Impact Assessment of EU policies has to be improved taking into account the perspective of, amongst others, cross-border areas. This article discusses the need and relevance of Cross-Border Impact Assessment to improve evidence-based policymaking, legislative procedure and implementation for (cross-)border regions through a multilevel governance approach. This special variation of the Territorial Impact Assessment may provide an opportunity for studying potential (cross-)border effects emanating from legislation systematically at the European level.
Evidence-Based Legislation in EU Competition Law

Evidence-Based Legislation in EU Competition Law. Reform of the Vertical Block Exemption Regulation as a Case Study

Whereas the European Commission’s Better Regulation Agenda advances a broad standard for evidence in legislation, EU competition law more narrowly relies on economic evidence focused on welfare effects. This article explores this inherent tension by means of a case study of the 2018-2022 revision of the Vertical Block Exemption Regulation (VBER). It is found that economic evidence has been only one of many sources of evidence in the VBER revision process, which put particular attention on evidence through stakeholder consultation. This is understandable within the context of the Better Regulation Agenda, but nonetheless striking when considering EU competition law’s reliance on economic evidence over non-economic evidence under the Commission’s ‘More Economic Approach’. Moreover, it is unclear why economic evidence was gathered to evaluate some aspects of the VBER and not on others. Furthermore, the Commission has been strategic in drawing conclusions from economic research and, considering the limitations thereof, seemingly based on its predefined preference for specific policy options.

Of Hypothesis and Facts: The Curious Origins of the EU’s Regulation of High-Risk AI

In the spirit of the European Commission’s (EC) risk-based approach to artificial intelligence (AI), the AI Act (COM(2021) 206 final) contains a four-level taxonomy of AI-related risks, ranging from non-high to unacceptable. For so-called high-risk AI, it sets out a priori technical standards, the observance of which is meant to prevent the occurrence of various types of harm. However, based on a quantitative/qualitative analysis of the results from two public consultations conducted by the EC, this study shows that the views gathered by the EC are not reflected in the AI Act’s provisions. Although in ‘standard’ EU risk regulation, the objective of attaining a desired level of protection can justify a regulatory address, evidence remains required, for the purpose of avoiding risk misrepresentations. Bearing in mind the requirement for evidence-based policy, expressed in the 2015 Better Regulation Agenda, this study argues that the AI Act, as it currently stands, is not based on the evidence gathered and analysed by the EC, but that a pre-existing policy strategy on AI seems to primarily – if not, exclusively – constitute the grounds on which the EC based the regulatory framework which took shape in the AI Act.

Assessing the Adequacy of Existing Multilateral Rules Regulating E-commerce: Lessons from EU Law

This article assesses the multilateral rules regulating e-commerce to identify their adequacies to provide the issues the European Union (EU) needs to consider as a player in World Trade Organization (WTO) e-commerce negotiations. The analysis uses six factors: facilitating imports and export, addressing tariffs as a form of government revenue, attracting investment, preserving policy space for digital industrialization, providing development assistance, and providing for different rights and obligations according to development levels. While existing multilateral rules have relevant provisions for regulating e-commerce, there are several limitations. The existing multilateral rules were designed to regulate broader issues, which ignore the new issues brought by digitalization. The EU Single Market, proposals for the digital services tax and the New Deal for Consumers provide important lessons that can help in shaping e-commerce rules at the WTO.

How Radical is the Understanding of Democracy in Justifying Contract in Europe?

Justifying Contract in Europe answers on every page the ‘so what’-question of why one should care about European contract law. I thoroughly enjoyed reading the engaging analysis of the normative foundations of law through the lens of six strands of political theory: utilitarianism; liberal-egalitarianism; libertarianism; communitarianism; civic republicanism; and discourse theory. In this short reflection, I will concentrate on one specific question, which seem, however, relevant to the entire inquiry of the book: Does Justifying Contract in Europe honor its expressly stated commitment to radical democracy? How does it deal, in light of the growing dissensus in Europe, with the need to provide institutional arrangements that equip a political system to turn unproductive antagonism into productive agonism?

Justifying Racial and Gendered Contract in Europe

Justifying Contract in Europe has the ambition to contribute to the envisioning of more just alternative futures by highlighting the normative stakes of contract law questions. This contribution asks what sort of just futures can be envisioned, if and when we remain focused on justifications that make gender and racial injustice invisible in the context of contract’s normative stakes. In particular, in this response, I offer a critique of the structural absence of intersectional feminist engagements with ideas of justice, democracy and freedom in discourse on justice and contract in Europe. The absence of feminist intersectional analyses undermines the diagnostic processes to identify root problems and the potential for radical reconsiderations for contract in Europe.

Searching for Contract (Law) in Europe

While investigating ways to Justifying Contract in Europe, Martijn Hesselink leaves it to the interrogated theories to define the scope of its very inquiry – the reach and significance of contract itself. This leaves the question of what Hesselink sets out to justify quite open for the reader, who at the same time gets the distinctive idea that this delimitation has normative significance in the author’s own views. To the extent that we do, as a matter of justice, need to have contract law rules – then, these rules need to be just. The comment, thus, seeks to re-articulate Hesselink’s non-definition of (European) contract law, to try to delimit where we need such rules and test the boundaries of what rules we may in fact accept or even need as a matter of justice – what kind of rules we can, in Hesselink’s framework, ultimately set out to justify.

The Power of Reasons in European Private Law

This article discusses the power of reasons in European private law. It does so in response to six articles written by critics, as part of a book symposium on Justifying Contract in Europe: Political Philosophies in European Contract Law (Oxford University Press, 2021). In particular, this contribution explores: the role of reasons in emancipatory political struggles; the meaning of reconciliation in pluralist societies; intersectional corrective justice through private law; the relationship between normative questions and critical theory; the priority of justice in times of crisis; and the politics of general private law theory.

Published: August 2022

Climate is a critical driver in shaping patterns of tree distribution and productivity in Canadian forests. Canada’s climate is changing and, as a result, tree populations may become maladapted to the climate at their current growing locations. In 2020, Ontario updated its tree seed transfer policy to respond to the evolving natural, operational, scientific, and policy environments, including a changing climate. Collaboration among federal and provincial science, operations, and policy staff was essential to update the policy, which involved a custom climate similarity analysis, a related assessment of critical seed transfer distances, various engagement efforts to assess end-user receptivity, and the development of an online interactive tool to allow users to explore seed transfer options under climate change. Here we describe several factors considered during the policy update, major steps in the update process, and highlights of the outcome. The intent of this effort is to support other jurisdictions considering similar changes and to emphasize the need for a changing culture in seed procurement and management.
The Impact of Leadership Style on Teachers’ Organizational Commitment
Authors:   University of Idaho, Kim Juhee
Published: August 2022

The study explores how transformational and transactional leadership styles affect teachers’ commitment in aspects of affective dedication, normative commitment, and continuance commitment. The research utilized the Multifactor Leadership Questionnaire (MLQ) to assess leadership styles of the 80 surveyed high school teachers. The results indicated that transformational and transactional leadership styles only enhanced the emotional attachment teachers have towards the school. Neither transformational nor transactional leadership styles could predict the moral obligation to stay in the school and weigh the benefits of leaving the school. It was recommended that organizational management encourage and inspire teachers through motivation to increase their level of commitment. School leaders and supervisors should prioritize regular leadership training and seminars for effective management to boost teacher commitment.

The new Schiff base, 2,2'-((1Z,1'Z)-(((propane-1,3-diylbis(oxy))bis(2,1-phenyle­ne))bis­(me­tha­­nyl­­ylidene))bis(azanylylidene))diethanol, was investigated as a cor­ro­sion inhibitor of aluminium in 1 M HCl. Polarization and electrochemical impedance mea­surements were used for this purpose. Polarization curves showed that the compound is a mixed-type corrosion inhibitor. Also, the results showed an increase in inhibition efficiency as the concentration of the compound increased. The maximum corrosion inhibition effici­ency of approximately 81 % was reached at the concentration of 2 mg/L of the inhibitor. The results of the density functional theory method were consistent with the experimental results. The surface morphology of the samples was examined under atomic force microscopy.

Published: August 2022

Diaphragmatic bronchogenic cysts are rare, and very few cases have been reported in the literature to date. Herein, we present a 42-year-old male patient who had a diaphragmatic bronchogenic cyst with the radiologic appearance of an intrapulmonary lesion as the 32nd case in the English literature. We performed a videothoracoscopic excision of the cyst, which was later found to be originated from the diaphragm. Pathologic examination confirmed the diagnosis of the bronchogenic cyst. Diaphragmatic bronchogenic cysts may present as intrapulmonary lesions radiologically. Videothoracoscopic excision is a feasible treatment method for these lesions.
The impacts of isolated N1 lymph nodes metastasis on prognosis in non-small cell lung cancer: A single-center experience
Authors: Fatih Sezer Hüseyin , Eliçora Aykut
Published: August 2022

Background: This study aims to investigate long-term results related to N1 group metastases with respect to anatomical localization and many external parameters and to examine the effect of these parameters on prognosis in patients with in nonsmall cell lung cancer.

Methods: Between January 2006 and May 2019, a total of 52 patients (44 males, 8 females; mean age: 59.9±9.5 years; range, 42 to 80 years) who underwent lobectomy due to primary lung malignancy were retrospectively analyzed. The N1 lymph nodes were divided into three anatomical groups as hilar, peribronchial, and intraparenchymal. Demographic features, tumor features, follow-up characteristics, and survival and diseasefree survival parameters were analyzed for each group. The results were also examined in terms of number of metastasis, number of metastatic levels, rate of metastasis, and histopathological type.

Results: The five-year survival rate was 66.4% in the peribronchial group and 50% in the hilar group. The five-year disease-free survival rate was 45.7% in the peribronchial group and 37.5% in the hilar group. There was no statistically significant difference between the groups in terms of survival and disease-free survival for anatomical localization, number of metastasis, number of metastatic levels, rate of metastasis, and histopathological type (p>0.05 for all).

Conclusion: The structure that would be formed by examining N1 in terms of parameters such as subtitle levels, number of metastasis, number of metastatic stations, rate of metastasis or combinations of these would have a more impact on the decisions in the follow-up and treatment process in this patient population.

Authors: Kozanlı Fatoş , Akkök Burcu
Published: August 2022

Background: In this study, we aimed to evaluate the diagnostic value of neutrophil and immature granulocyte levels in peripheral blood in cases with pleural effusion.

Methods: Between May 2019 and May 2020, a total of 117 patients (43 males, 74 females; mean age: 63.1±18.1 years; range, 18 to 93 years) who had pleural effusion and analysis of pleural fluid were retrospectively analyzed. All patients were evaluated in terms of age, sex, presence of comorbid diseases, approach to the pleural fluid, biochemical values of peripheral blood and pleural fluid, hemogram series of peripheral blood, diagnosis of pleural fluid, and mortality.

Results: Of the patients, 66 (54.5%) were diagnosed with benign pleural effusion and 51 (43.5%) were diagnosed with malignant pleural effusion. Number of cases with known primary malignancy was 54 (46.1%). Immature granulocyte count number and percentage of venous blood in the malignant pleural effusion group was significantly higher than the group with benign pleural effusion (p<0.05).

Conclusion: As a hemogram parameter, immature granulocyte level is an easily applicable, cheap, and a non-invasive method in the outpatient settings.

Authors: Terzioğlu Emrah , Damar Çağrı
Published: August 2022

Background: The aim of this study was to evaluate the aortic arch morphologies in the Turkish population using the computed tomography angiography technique.

Methods: Between August 2009 and August 2019, a total of 2,037 (1,003 males, 1,034 females; mean age: 52.8±20.3 years; range, 3 months to 100 years) thoracic computed tomography angiography scans were retrospectively analyzed. The findings were classified as described previously in the literature. The prevalence of aortic arch morphologies and possible relationship with sex were analyzed. The prevalence of variations reported in previous studies was compared with the current study.

Results: The normal aortic arch pattern (type A), observed in 1,562 cases (76.7%), was determined statistically significantly more in males than females (p<0.05). The most common variation, bovine aortic arch (type B1) which observed in a total of 315 cases (15.5%), was determined statistically significantly more in females than males (p<0.05). The second most frequent variation, in which the left vertebral artery originates directly from the aortic arch (type C1) was detected in 97 cases (4.7%). There was also observed to be aberrant right subclavian artery in 21 cases (1%), right-sided aortic arch variation in seven cases (0.4%), and double aortic arch anomaly in four cases (0.1%). In terms of the reported frequency of type B variation, a significant difference was determined between the current and previous studies in Türkiye (p<0.05).

Conclusion: With the largest sample size to date, this study provides comparative information about the prevalence of aortic arch patterns in the Turkish population.

Background: The aim of this study was to analyze the effect of additional lower body perfusion, compared to antegrade selective cerebral perfusion, on early postoperative outcomes after aortic arch repair in neonates with biventricular morphology.

Methods: Between January 2017 and April 2020, a total of 46 neonates (34 males, 12 females; median age: 10 days; range, 7 to 14 days) with biventricular morphology underwent an aortic arch reconstruction were retrospectively analyzed. The effects of antegrade selective cerebral perfusion and additional lower body perfusion techniques on vital organ preservation and mortality were evaluated in these patients who underwent arch reconstruction.

Results: In the univariate analysis of the whole cohort, postoperative creatinine level was lower in the additional lower body perfusion group, while there was no significant difference between the other parameters. In the multivariate analysis, intraoperative highest lactate level (odds ratio: 1.7; 95% confidence interval: 1.07-2.68; p=0.02) and postoperative 4th t o 6 th h lactate levels (odds ratio: 2.34; 95% confidence interval: 1.08-5.09; p=0.03) were independent predictors of early mortality. Mortality rate was higher in the antegrade selective cerebral perfusion group (22% vs. 7%), although it did not reach statistical significance. In the receiver operating characteristic curve analysis, the cut-off value for intraoperative lactate was 6.2 mmol/L (sensitivity: 85.7%, specificity: 71.1%) and the cut-off value for the lactate level at the postoperative 4th to 6th h was 4.9 mmol/L (sensitivity: 85.7%, specificity: 73.7%). Above these lactate levels were found to be associated with mortality.

Conclusion: Additional lower body perfusion may have a role in vital organ protection in aortic arch repair of neonates, compared to antegrade selective cerebral perfusion.

This study investigated into the floristic abundance and diversity of mangrove in polluted soils in Ikuru town, Andoni Local Government Area, Rivers State. The study covered an area of about five hectares (ha) of land. The area was measured using a transect of 100m x 20m in each zone. 10m transects were used in the experimental study. A control was chosen within the mangrove forest at Eagle Island Port Harcourt. Soil samples were randomly collected from subtidal, middle intertidal and lower intertidal zones, and control location using soil augar. Composite soil Samples were carefully placed into well labeled poly bags for laboratory analysis. Standard sampling procedures were adopted for soil physical and chemical analysis. Floristic species richness and diversity were also accessed. The results of the floristic compositions of the mangrove tree species in the hydrocarbon polluted soil of Ikuru Town showed that five (5) species, Avicenmia, Rhizophora mangle, Laguncularia racemosa, Acrostichum aureum, Rhizophora racemosa, four (4) families; namely Avicenmia, Avicenruocerae, Rhizophoraceae, Combitaceae and Pteridaceae. Furthermore, the results also showed that in polluted soil, Avicennia germinas recorded (35); unpolluted (52); Rhizophora mangle polluted (22); unpolluted (35); Lagunculania, racemosa polluted (20); unpolluted (30); Acrostichum aureum polluted (25); unpolluted (25); Rhizophora racemosa polluted (42) and unpolluted (60); Axonopus compresus polluted (15) unpolluted (20) and Cynodon dactylon polluted) (10) unpolluted (22) However, the diversity of the mangrove species in both polluted and contro soils were significantly different (P≤0.05), Avicennia gramina (35.52), Rhizophora mangle (22.35); Laguncularia racemosa (20.30), Acrostichum aureum (25.30) and Rhizophora recemosa (42.60). The results showed that the percentage abundance of the mangrove species differ in the percentage occurrence of the species found in the mangrove ecosystem, Rhizophora racemosa (24.88%, 25.49%) in both polluted and control soils, followed by Avicemmia Africana (20.71%; 21.3%) and the least abundant species was Laguncularia racemosa (11.82%; 12.30%).

The study examines the effect of monetary policy on commercial bank’s lending operation in Nigeria between February, 1991 to October, 2020 using the macroeconomic time series variables of exchange rate, interest rate, maximum lending rate and prime lending rate. The vector error correction model was employed to analyze these interactions as well as the effect and pattern of causality among the variables under investigation. Monthly data spanning from February, 1991 to October, 2020 which covered a period of 29 years and 7 months (357 observations) were sourced from the Statistical Bulletin of the Central Bank of Nigeria (CBN). Preliminary statistical approach such as descriptive statistics and time plot were carried out to test if the data set obey the normality assumption and to verify if there is trend on the series. Pre-estimation diagnosis such as unit root test, lag order selection criteria and co-integration test were carried out and the results shows that at level, all variables had unit root, then, at first difference all variables were stationary. The lag order selection criteria chose lag 3 (14.7844*) of Akaike information criteria, but the vector error correction model (VECM) was done at lag 2 indicating losing a lag. The co-integration test shows the presence of long run relationship among the variables. The vector error correction model (VECM) estimated from the results obtained shows that all the variables had positive effect on commercial bank’s lending operation. The post estimation test on vector error correction model such as normality of the residuals, serial correlation and heteroscedasticity shows that the VEC model was multivariate normal, no serial correlation and homoscedastic. The inverse root of AR characteristic polynomial shows that the estimated VECM satisfy the stability condition of the diagnostic test. The variance decomposition test shows that the variables have a very weak influence in predicting one another. Recommendations were made based on the result of findings in the study

Sustainable economic development through future societal value has conquered a central theme on the academic interest of recent time. The well being of child’s future has direct link with the present time activities of the government, community, organizations, family and parents to protect them. Thus fulfilling their rights and values at early stage of childhood will certainly transform them to achieve their full potentials and to participate actively in the society. The study descriptively analyzed the child poverty situation in Nigeria by comparing the changes between 2000 and 2007. Similarly the paper adopted the model “B” of Faith and Holland,(2007) and Bristol approach for the situational analysis in Nigeria. Simple mathematical tool for assessing the differential changes of the period under review was employed. The result revealed that there are prevalence of severe deprivation in shelter, sanitation and nutrition, education and health positively increased by 11.1%; 7.7%; 50.0%; 36% and 17.5% respectively while water and information drastically increase by -15.9% and -48.6 respectively (In essence only information and water supply contribute to children wellbeing). The paper recommends that, policy makers should restructure the existing social policies and service delivery to children and young persons

The study investigates GARCH Model in modeling of the returns on Nigeria’s agricultural food export price, specifically to; determine whether Nigeria agricultural export Prices can be fitted to a volatility model, to test the present ARCH effect in the return volatility of Nigeria agricultural export Prices and determine the impact of price volatility in Nigerian Agricultural export markets. Using the cotton price to represents Nigeria agricultural export price, the logarithm returns for various months were computed, descriptive statistics of the logarithm returns was calculated and the volatility of the market was estimated using the standard deviation and the addition of the ARCH and GARCH components of the GARCH model was done to the determine persistence of volatility impact . It was found that the Agricultural export market has volatility of 0.514 with 88.3% persistence of volatility impact between 1992 to 2020. This show that the market is highly volatile within period under investigations than the period preceding it. The recommendation is that the depth of instruments in the Agricultural export market should be varied in terms of fixed tradable financial instruments used to raise capital in the Agricultural export market than concentrating on the would be returned to the marketer if all of the assets were wind up and all of the marketer’s debts were paid off

In the field of educational studies, academic engagement has become an important perspective in the domain of achievement motivation particularly in academic motivation. The study aimed to explore the students’ academic engagement as predictor of academic achievement in mathematics in Anambra State. The study adopted a multiple regression predictive design. The population of the study comprised of 21,204 SS II students from which a sample of 1500 were drawn. Multi-stage procedure was used to select the sample. Students’ Academic Engagement Questionnaire (SAEQ) was used for data collection. Students’ mathematics achievement scores from the state wide promotion examination were used to represent mathematics achievement. Cronbach’s alpha was used to determine the reliability of the items in the instruments. Reliability indices were found to be .75, for behavioural engagement, .83, for psychological engagement, .87, for cognitive engagement, .61, for emotional engagement, .84, for agentic engagement and .73 for social engagement. The overall reliability coefficient was .74 which shows that the instrument was reliable and good for the study. Four research questions and three nu ll hypotheses were formulated for the study. The standard multiple regression was used to analyze the collected data. The t-test for r, F-test and test of significance for β, were used to test hypotheses at .05 level of significance. Findings showed that social engagement is the most predictor of students’ academic achievement in Mathematics when compared with the other dimensions of academic engagement . Also, the analysis of variance indicated that the regression equation was significant in predicting academic achievement. This implies that at least one of the independent variables significantly predicted academic achievement in Mathematics... Based on these findings, it was recommended that using students’ academic engagement as a predictor of academic achievement would enable the academic institutions to identify at risk students much earlier compared to using only cumulative grade point average; which is a product of measure. This would enable academic institutions to formulate more effective intervention strategies to reduce attrition rate

This research work examined pressure relief valve (PRV) failures by using statistical analysis of proof test data obtained from the computerized maintenance management system (CMMS) of Liquefied Natural Gas (LNG) facilities site. This study comparatively investigated the 30 months approved inspection interval for the proof test of PRVs by the Department of Petroleum Resources (DPR) of Nigeria. In this research, failure rate and failure behaviour of PRVs were evaluated and analyzed using bathtub curve. Aging effect of PRV using regression analysis and the cause of failures were also analysed. Least square multiple linear regression was the statistical tool used for the analysis with the aid of EXCEL. After thorough analysis, the study depicted drop in failure rate at different times (years) at the bathtub curve. Also, the statistical analysis found that the ageing effect from five spring loaded PRVs evaluated was at most 0.4% per year with 95% confidence and the amount of variance explained per time was minimal (R-Square 7.6%). It was recommended that the inspection interval (30 months) as approved by DPR for proof test of PRVs was optimal with regard to the required integrity condition of the PRVs since test frequencies yielded better result and consequently less risk. Also, further testing and investigation should be pursued to determine if longer intervals between inspections were possible. Furthermore, analysis from the investigation of cause of failure showed that corrosion was a cause of PRV failure and contact area factors such as sticking and cold welding

Nigeria bears the heaviest malaria burden of any single nation in the world and has relentlessly pursued the elimination of the disease. One of the key strategies for the elimination of malaria is increasing the specificity and sensitivity of surveillance. To this end, this study sought to determine malaria transmission along an altitudinal gradient of Plateau state, central Nigeria, while examining socio- demographic factors affecting the prevalence of malaria at these sites. Three communities each at high and low elevation areas of Plateau State in central Nigeria were surveyed for incidence of malaria cases. Information on age, gender, use of long-lasting insecticide treated nets, pregnancy status in women, and, malaria severity were recorded in 1700 study subjects. Using venipuncture method, 4ml blood samples were collected in EDTA vials for laboratory analyses. Microscopy (thick and thin blood smear techniques) and Rapid Diagnostic test were used to detect malaria parasites and determine the Plasmodium species involved. Using a propriety application (ELDACAP), real time geolocation data, socioeconomic, health, and preventative status information were also collected from all 1700 respondents. Our findings showed more cases of malaria prevalence in lowland areas compared to highland areas. The main predictors of malaria incidence were age, sex, use of ITN and the presentation of symptoms. Non-net users had more prevalence of malaria compared to users, males had a higher positive frequency compared to females, and malaria was more prevalent in the younger age group compared to older group. Malaria eradication in north-central Nigeria must take into account geographic differences, cultural and social practices, previous anti-malaria preventative measures (use of ITN), as well as the presence of asymptomatic malaria carriers who serve as reservoir in the population
