Le miles œconomicus , enfant du patriotisme britannique
Authors: Tixier Caroline
Published: October 2020

Les politiques néolibérales menées depuis le commencement des années 1980 ont particulièrement contribué à transformer le patriotisme britannique. Le mythe du héros sacrificiel s’est en effet effacé, à la faveur de mesures tendant à privatiser certains secteurs de la Défense. C’est dans ce cadre qu’est apparu un soldat d’intérêt – un miles œconomicus – dont les traits se sont affinés grâce au développement des sociétés militaires privées au Royaume-Uni. Ces dernières, spécialisées dans la gestion des risques internationaux, autoentretiennent un système d’expertise de l’insécurité mondiale. Dans ces conditions, elles tendent à éroder progressivement l’institutionnalisation de la guerre et à désincarner le don sacrificiel auquel était autrefois associée la représentation du soldat héroïque. Cet article entend rendre compte de ce processus.
Gaullisme et extrême droite : l’impossible amalgame
Authors: Aromatorio Sylvano
Published: October 2020

Le général de Gaulle et le gaullisme font de plus en plus l’objet de récupération politique dans l’extrême droite. Une récupération surprenante tant les racines historiques de l’extrême droite se présentent comme antigaullistes. Des éléments pourraient laisser à penser une proximité notamment à travers des thèmes comme l’État ou la Nation. C’est sur ces thèmes que l’extrême droite utilise l’amalgame. Mais tout est différent, l’État chez les gaullistes n’a rien à voir avec le culte de l’État de l’extrême droite et le sentiment national du gaullisme est étranger au nationalisme xénophobe de l’extrême droite. Seule l’analyse des fondements caractéristiques de ces deux courants peut permettre de comprendre l’ampleur de leurs différences.
Instituciones sociorreligiosas judías de Zaragoza (siglos XIV-XV). Sinagogas, cofradías, hospitales
Authors: Blasco Martínez Asunción
Published: October 2020

Mediante la utilización combinada de documentos procedentes de protocolos notariales y registros de cancillería real, y el hábil manejo de la bibliografía existente, la autora realiza un estudio sistemático y exhaustivo de las instituciones sociorreligiosas registradas en la aljama de judíos de Zaragoza en los siglos XIV-XV. En primer lugar, se estudia la sinagoga, centro de la vida pública del pueblo judío. El segundo apartado está dedicado. a las cofradías y es el más extenso, pues son catorce las hermandades documentadas en la ciudad: once socio benéficas (de asistencia al desva­lido y al enfermo, de atención al estudio, de preocupación por el difunto) y tres socio laborales (de zapateros, baldreseros y pellejeros). El trabajo se completa con la presentación y análisis de la organización hospitalaria de la aljama.

Interactions entre gestion personnelle de l’information et connaissances professionnelles des enseignants. Le cas de l’informatique et sciences du numérique (ISN)
Authors: Drot-Delange Béatrice
Published: October 2020

Dans cet article, nous analysons les interactions entre gestion personnelle des ressources et connaissances professionnelles des enseignants. La gestion personnelle de l’information est étudiée via les opérations de documentarisation classificatoire, c’est-à-dire le classement, le nommage et l’indexation des ressources (Zacklad et al., 2011). Les connaissances professionnelles des enseignants concernent les connaissances disciplinaires, pédagogiques et curriculaires des contenus (Shulman, 2007). Les interactions sont analysées dans le contexte de l’enseignement de spécialité de l’informatique et sciences du numérique (ISN) ouvert en 2012 dans les classes de terminale. Nous avons mené des entretiens auprès de cinq enseignants. Nous avons complété ce recueil de données avec les produits observables de la gestion personnelle de l’information : les arborescences des dossiers et des marque-pages. Les résultats montrent que les différentes opérations de documentarisation classificatoire visent d’abord un besoin de réassurance des connaissances. Ce besoin peut concerner la préparation des cours ou l’activité en classe. Il est soutenu par une ou des collections de référence (Jones, 2007), par un classement permettant la réactivité en classe et par des supports personnels toujours disponibles.
Participatory Action Research as/in Adult Education
Authors: Call-Cummings Meagan , Hauber-Özer Melissa
Published: October 2020

Participatory action research (PAR) is an embodied form of inquiry that engages those most affected by an issue or problem in creating knowledge and developing solutions. PAR epistemology intersects with the critical approach to adult education, particularly the belief that programs, methods, and content must be relevant to learner needs and challenges and ought to lead to greater social justice. The purpose of this paper is to offer a review of three critical, participatory inquiry methods that are anchored in three concepts foundational to PAR and to present readers with a useful description of how to implement these methods in diverse contexts.
Product Categorization for Social Marketing Applying the RFC Model and Data Science Techniques
Authors: Zaw Myint , Tandayya Pichaya
Published: October 2020

Currently, it is the age of social market due to the growth of internet technologies. The marketers require the complete information of customer perspectives on products and services comparing with others. The RFM (recency, frequency, and monetary) model is a technique to measure a comparison of information, especially in traditional market analytics. Over the past decade, social market big data (SMBD), especially feedback, has been used to understand customer satisfaction. This paper proposes a new approach to classify the products from feedbacks, called the RFC (recency, frequency, and credit) model. The model focuses on the social market information and product categorization applying the natural language processing (NLP), opinion mining (OM), and data mining (DM) techniques.

Published: October 2020

Children and teenagers that have been victims of bullying can possibly suffer its psychological effects for a lifetime. With the increase of online social media, cyberbullying incidents have been increased as well. In this paper, the authors discuss how they can detect cyberbullying with AI techniques, using term frequency-inverse document frequency. The authors label messages as benign or bully. The authors want their method of cyberbullying detection to be privacy-preserving, such that the subscribers' benign messages should not be revealed to the operator. Moreover, the operator labels subscribers as normal, bully, and victim. The operator utilizes policy control in 5G networks to protect victims of cyberbullying from harmful traffic.
Synchronization-Aware Task Allocation Techniques for Preemption Control to Reduce Blocking Time in Multiprocessor Real-Time System
Authors: Kumar Ajitesh , Gupta Sanjai Kumar
Published: October 2020

Multiprocessor real-time systems receive a great deal of attention. For better utilization of multiprocessors in a real-time context, an optimal approach for scheduling, allocation, and synchronization is required. In this research, a novel heuristic synchronization-aware scheduling has been proposed to reduce the blocking delays in a critical section and also bound to minimize multiple priority inversion. The key idea of this technique is to assign the task set in the same processor that accesses a common shared resource and also access them for the longest period of time; thereby, the global sharing of resource transforms into local sharing. From simulation results, it was concluded that the duration of blocking overheads should be minimized up to 25% to 30% and context switching between processors also reduced up to 10% to 15%. On the basis of result analysis, schedulability, minimization of context switching, and reduced blocking time indicate that the proposed method outperforms the existing methods and does not affect the task completion time.
Conversational Frames
Authors: Almousa Omar Saad , Migdady Hazem , Al-Talib Mohammad
Published: October 2020

This paper extends the previous work of Almousa and Migdady by proposing and implementing three models to improve the correctness and naturality of the given answers of smart personal assistants (SPAs). The motivation behind the three proposed models is the failure of some well-known existing SPAs (Siri and Salma) to extract contextual information from a conversation. The authors call this kind of information: the conversational frame. For evaluating the suggested models, the authors also implement an abstraction of the existing SPAs that they call non-framed model. To evaluate the four implementations, 36 respondents answered an on-line questionnaire after watching four videos that the authors recorded per implementation. The authors statistically prove that their three suggested models precede the non-framed model. The researchers attribute this to the fact that our models overcome the shortcoming present in non-framed model. Moreover, their model that implements the conversational frame precedes all other models.
A Parsimonious Predictive Model of Movie Performance
Authors: Canbolat Mustafa , Sohn Kyongsei , Gardner John T.
Published: October 2020

In this paper, the authors develop a parsimonious model that offers early prediction of potential success of a movie. In order to achieve this, a broad look at the drivers of movie success is required. Supply chain members will be making decisions regarding movie popularity with regard to licensing contracts, forecasting toy purchases, cross-promotions, etc. at varying times before a movie is released. A simple forecasting approach using publicly available data could improve supply chain decision making. Prior literature suggested that the virtual movie stock market, HSX, was a good predictor. Using a small set of variables including view counts, likes, and dislikes did offer some predictive value. However, HSX produces a forecast that dominates prior models while using a single readily available public data. Further, the HSX-based prediction showed consistency and convergence across a significant breadth of time.

Authors: Zonatto Vinicius Costa da Silva , Bauer Liliane , Degenhart Larissa , Nascimento Juliana Constâncio
Published: October 2020

Este estudo objetivou avaliar os efeitos cognitivos, motivacionais e do valor de realização da participação orçamentária sobre o desempenho no trabalho. Este artigo apresenta os resultados de um estudo que reexamina o modelo teórico de análise desenvolvido por Chong, Eggleton e Leong (2006). A amostra da pesquisa compreendeu 121 gestores com responsabilidade orçamentária de organizações industriais do Estado de Santa Catarina (SC). Os resultados suportam os diversos papéis da participação orçamentária, pois esta variável apresentou efeitos positivos na satisfação e desempenho dos gestores no trabalho. O comprometimento organizacional também evidenciou uma relação positiva com a satisfação e o desempenho do indivíduo no trabalho. Estes achados revelam que a participação orçamentária proporciona o aumento da satisfação no trabalho e potencializa o desempenho dos gestores. Uma vez satisfeitos com o trabalho, comprometem-se mais com a organização, o que consequentemente apresentou reflexos positivos no desempenho dos gestores em atividades orçamentárias. A partir dos resultados, não pode-se confirmar que a participação orçamentária reduz os níveis de ambiguidade de papéis. Conclui-se que a participação orçamentária produz efeitos do valor de realização (satisfação no trabalho), que influenciam positivamente o desempenho no trabalho. Os resultados oferecem suporte para que as organizações industriais direcionem esforços para práticas organizacionais que visam melhorar as definições das responsabilidades e os objetivos do cargo de controller, com vistas a aumentar o comprometimento destes com a organização, sua satisfação no trabalho e o seu desempenho em atividades orçamentárias.
The effect of danusertib, an Aurora kinase inhibitor, onto the cytotoxicity, cell cycle and apoptosis in pancreatic ductal adenocarcinoma cells
Authors: Kirbiyik Ismail Ayberk , Ozcimen Ahmet Ata
Published: October 2020

Background:

Pancreatic cancer is the second type of cancer that causes the most death among the digestive system cancers. Difficulties in early diagnosis and rapidly progressing to advanced stages are most common in high mortality rate of pancreatic carcinoma. The mutation of Bcr-Abl tyrosine kinase and mitotic kinases (such as Aurora kinases), which are involved in the cell cycle, plays an important role in the progression of cancer. Enzymes belonging to Aurora kinase family (-A, -B, -C) have been reported to play a major role in cancer progression, invasion and metastasis. Therefore, the purpose of this study, investigate of the effect of danusertib, an Aurora kinase inhibitor, onto cytotoxicity, apoptosis and cell cycle in human pancreatic carcinoma CFPAC-1 cells.

Materials and Methods:

For determining the IC50 value, the 20,000 cells were seeded in E-plate 16 wells in a real-time cell analyzer and various concentrations of danusertib (1-10,000 nM) were applied onto CFPAC-1 cells incubated in IMDM medium. Cell index demonstrated that the proliferation of fraction cells was measured in real time. On the other hand, cell apoptosis and cell cycle arrest test were stained with Annexin V-APC/PI and DNA-cell cycle PI staining respectively by using flow cytometry.

Results:

The IC50 value was found to be approximately 400 nM. Danusertib at this concentration induced apoptosis in CFPAC-1 cells (%14,8 at 24 hours; %21,3 at 48 hours). Furthermore, in the cells treated with danusertib, 31.77% and 11.05% were arrested in the S and G2 phases, respectively.

Conclusions:

Aurora kinase inhibitor danusertib induced a significant effect of cytotoxic, apoptotic and cell cycle arrest in CFPAC-1 ductal adenocarcinoma cells. Therefore, it may be a potential alternative to the treatment of pancreatic cancers.

Authors: Lin Shinn-Long , Yeh Chun-Chang , Wu Zhi-Fu , Pan Ru-Yu , Tseng Wei-Cheng
Published: October 2020

Intracranial subdural hematoma (ICSH) is a rare complication of spinal anesthesia (SA). Because of similar characteristics with postdural puncture headache (PDPH), the definitive diagnosis of ICSH is usually delayed or masked, which potentially results in morbidity or mortality. Herein, we report the case of a young male who developed ICSH following SA and emphasize the differences between ICSH and PDPH in terms of atypical presentations. Furthermore, this report aims to identify the criteria for performing an epidural blood patch in patients with ICSH after dural puncture.

Published: October 2020

We report a case of a patient with schizophrenia-like disorder related to the right-side frontal lobe meningioma and oral cancer. This 55-year-old female began to show symptoms of talking to herself, insomnia, psychomotor agitation, persecutory delusions, violent behavior, and auditory and visual hallucinations, after the surgery for her oral cancer. The brain imaging studies revealed one right frontal lobe meningioma. The combination of risperidone and fluoxetine has successfully resolved the schizophrenia-like psychotic disorder related to both frontal lobe meningioma and mood disorder related to the body disfigurement due to the oral cancer surgery. This report aims to serve as a reminder for clinicians who are responsible for the treatment of the psychotic disorders in patients with concurrent brain and extracerebral tumors.

Published: October 2020

Purpose The soluble form programmed death-ligand 1 (sPDL1) has immunosuppressive properties and is being studied as a candidate biomarker for immuno-oncology drug development. We measured the serum sPDL1 at pre-and post-chemotherapy and evaluated its prognostic implication and dynamics during chemotherapy in advanced gastric cancer (GC).Materials and Methods We prospectively enrolled 68 GC patients who were candidates for palliative standard first-line chemotherapy, and serially collected blood at baseline and after one cycle of chemotherapy, at the best response and after disease progression. sPDL1 was measured using an enzyme-linked immunosorbent assay. Response to chemotherapy, overall survival (OS), progressionfree survival (PFS) and other prognostic factors including neutrophil-lymphocyte ratio (NLR) were obtained. The cut-off value of sPDL1 levels for survival analysis was found using C-statistics.Results The median baseline sPDL1 was 0.8 ng/mL (range, 0.06 to 6.06 ng/mL). The median OS and PFS were 14.9 months and 8.0 months, respectively. sPDL1 and NLR showed a weak positive correlation (Spearman’s rho=0.301, p=0.013). Patients with low levels of sPDL1 at diagnosis (< 1.92 ng/mL) showed a better OS and PFS than patients with a high sPDL1. The baseline sPDL1 before treatment was higher in the progressive disease group than in the stable disease and partial response groups. Patients whose sPDL1 increased after the first cycle of chemotherapy showed worse PFS and OS. Following disease progression, sPDL1 increased compared with the baseline.Conclusion sPDL1 at prechemotherapy confers a prognostic value for PFS and OS in GC patients under palliative first-line chemotherapy. Dynamics of sPDL1 during chemotherapy correlates with disease progression.

Purpose Decision-making for treatment of newly diagnosed prostate cancer (PCa) is complex due to the multiple initial treatment modalities available. We aimed to externally validate the SCaP (Severance Study Group of Prostate Cancer) Survival Calculator that incorporates a long short-term memory artificial neural network (ANN) model to estimate survival outcomes of PCa according to initial treatment modality. Materials and Methods The validation cohort consisted of clinicopathological data of 4,415 patients diagnosed with biopsy-proven PCa between April 2005 and November 2018 at three institutions. Area under the curves (AUCs) and time-to-event calibration plots were utilized to determine the predictive accuracies of the SCaP Survival Calculator in terms of progression to castration-resistant PCa (CRPC)–free survival, cancer-specific survival (CSS), and overall survival (OS). Results Excellent discrimination was observed for CRPC-free survival, CSS, and OS outcomes, with AUCs of 0.962, 0.944, and 0.884 for 5-year outcomes and 0.959, 0.928, and 0.854 for 10-year outcomes, respectively. The AUC values were higher for all survival endpoints compared to those of the development cohort. Calibration plots showed that predicted probabilities of 5-year survival endpoints had concordance comparable to those of the observed frequencies. However, calibration performances declined for 10-year predictions with an overall underestimation. Conclusion The SCaP Survival Calculator is a reliable and useful tool for determining the optimal initial treatment modality and for guiding survival predictions for patients with newly diagnosed PCa. Further modifications in the ANN model incorporating cases with more extended follow-up periods are warranted to improve the ANN model for long-term predictions.

Published: October 2020

PurposeThis study investigated the incidence and relative survival rates (RSRs) for cancers among adolescents and young adults (AYAs) aged 15-39 years between 1993 and 2016 in KoreaMaterials and MethodsData from the Korea Central Cancer Registry were used to calculate percent distributions, age-specific incidence rates, age-standardized incidence rates (ASRs) per million, annual percent changes (APCs), average APCs, and RSRs for cancers diagnosed in AYAs.Results ASR of all cancers among AYAs was 654.5 per million. The largest diagnosed group of cancers was carcinomas (almost 80%). Crude incidence increased with age, from 170.4 per million for those aged 15-19 years to 1,639.8 per million for those aged 35-39 years. ASR increased from 414.8 per million to 820.4 per million, with an APC of 9.0%. The incidence of thyroid carcinoma showed the most rapid increment (APC, 14.0%), followed by non-Hodgkin lymphoma (APC, 13.4%). The 5-year RSR among AYAs significantly improved from 62.1% to 90.8%. Survival improvement in AYAs was higher than that in children but lower than that in older adults (APC, 2.1% vs. 1.9% vs. 3.1%). The most marked survival improvement was found for leukemia and lymphoma. Astrocytoma, rhabdomyosarcoma, and carcinoma of the trachea, bronchus, and lung had a 5-year RSR of < 50%.ConclusionThere was an improvement in cancer survivals in AYAs, comparable to that achieved in children. However, survivals in several cancer types do not appear to be improving. Further research focusing on the epidemiology and therapeutic strategies for cancers in AYAs is needed.

Published: October 2020

Cassava brown streak disease (CBSD) and cassava mosaic disease (CMD) are the major viral diseases of cassava in Uganda. Although isolation distance of “50 m” has been recommended by MAAIF in Uganda for prevention of virus infections in crops, the minimum isolation distance has not been verified for effectiveness in cassava. This study assessed the effective isolation distance for management of viral diseases in cassava. Virus-clean cassava cultivars (NASE 03, NASE 14 and NAROCASS 1) from farmers’ fields were used as field sourced (FS) planting materials. Tissue culture (TC) material of the same cultivars were sourced from the National Crops Resources Research Institute and Makerere University Agricultural Research Institute tissue culture laboratories. Both FS and TC materials were tested at isolation distances of 50, 100, 150 and 250 m for virus prevention. The experiment was laid out in a randomised complete block design and was run for 12 months after planting (MAP). Mean CBSD/CMD prevalence significantly varied (P<0.05) among isolation distances in both FS and TC plants, and the 250 m isolation distance was the most effective in reducing disease prevalence. Across cultivars and planting material category at 12 MAP, the 50 m isolation distance had the highest foliar incidence for CBSD (29.2%) and CMD (16.1%); while severity for CBSD was 1.4 and 1.2 for CMD. At 250 m, all FS and TC plants had CBSD/CMD severity of 1.0 and 0% incidence. These results show that 250 m isolation distance can provide an option to disseminate popular, but CBSD/CMD susceptible cassava cultivars thereby manage CBSD/CMD.

Authors: Kereilwe D. , Emongor V.E. , Oagile O. , Phole O.
Published: October 2020

Safflower (Carthamus tinctorius L.) is a multipurpose crop, grown for its high quality edible oil (poly unsaturated and monounsaturated fatty acids), and as a horticultural crop (vegetable and cut flower). It is also grown for flavouring and colouring foods, as herbal tea, livestock feed, pharmaceuticals, dyes, paints and biodiesel.The objective of this study wasto evaluate the influence of safflower genotype on the nutritional quality of whole seed used as livestock feed. Nine safflower genotypes (eight exotic and one local) were grown in winter and summer. The seeds were harvested at physiological maturity and analysed for different nutritional variables. Whole safflower seeds dry matter (DM), crude protein (CP), neutral detergent fibre (NDF), acid detergent fibre (ADF), acid detergent lignin (ADL) and ash varied significantly, depending on genotype and growing season. The seed mineral content (P, K, Mg and Na) also varied across genotypes. Safflower whole seeds have great potential to serve as an excellent livestock feed in semi-arid conditions.
Comparative study on spawning success of paradise fish (Macropodus opercularis) using synthetic hormone and natural simulation
Authors: Onuoha P.C. , Elezuo K.O. , Okeke E.G.
Published: October 2020

Synthetic hormones are widely used for induced breeding with significant successes. This study compared spawning successes in paradise fish (Macropodus opercularis) using synthetic hormone (Ovaprim) and natural simulation in glass tanks (0.3m x 0.6m). The experiment was conducted in two parts using two males and two females brood fish. The weights of the fish were between 4.0 and 5.0g for the males and 5.0 and 6.0g for the females. For the induced spawning, Ovaprim was injected intramuscularly according to the fish body weight after which they were left to spawn. The group on natural spawning were not induced by any hormone. Hatching of the eggs occurred within 48 hours at a temperature of 28.80C. Total number of eggs obtained by artificial and natural breeding were 430 and 322eggs respectively. Percentage fertilization in artificial breeding was 63.26% while 41.93% was recorded in natural breeding. Fry were raised on compounded diet for 6 weeks. Results showed that artificially bred fish had a higher mean weight gain (2.31 g) and survival rate (48.17%) than those from natural breeding having 2.10 g and 44.26% respectively. The results suggest that artificial breeding using synthetic hormone (Ovaprim) yielded better spawning success and survival rate than natural process.

Published: October 2020

The study was conducted to assess the reproductive biology and condition index of Pseudotolithus typus in Qua Iboe Estuary using standard methods. A total of 580 fish specimen were sampled over a period of 8 months (January – August, 2018). Condition index was generally low with the highest value of 1.03 recorded in the month of April. The overall mean condition index significantly deviated (p<0.05) from the expected value of 1.0. Male-female ratio of the species showed female dominance. Significant variation (p<0.05) were observed in condition and gonadosomatic indices with peak values in the months of March and July for females. Male fish showed no seasonality in gonadosomatic index. The average fecundity ranged from 2140 eggs to 8560 eggs with mean value of 4891±641 eggs. Positive correlation was observed between fecundity and total length, body weight, standard length and gonad weight of the fish. Thus, it could be concluded that P. typus is a dual seasonal spawner having spawning periods early in the year (March) and in the peak of wet season (July).

Authors: Emengini Boniface , Omenyi Ada Sam , Nwankwo Christopher Amobi
Published: October 2020

The study investigated organizational culture as correlate of teachers’ job performance and attitude to work in secondary schools in Anambra State, Nigeria. Five research questions guided the study and six null hypotheses were tested. The study adopted correlational survey research design. The population of the study comprised all the 6396 teachers in public secondary schools in the state. Out of the population, a sample size of 1279 teachers was drawn through proportionate stratified random sampling techniques. Data was collected using three different questionnaires developed by the researchers. The questionnaires include school organizational culture questionnaire (SOCQ), Teachers’ job performance questionnaire (TJPQ) and Teachers’ attitude to work questionnaire (TAWQ). The instruments were validated by three experts from Faculty of Education Nnamdi Azikiwe University Awka. Cronbach Alpha method was used to determine the reliability of the instruments which yielded a reliability coefficient of .959, .957 and 0.701 respectively. The reliability indices were considered high enough and thus the instruments were deemed reliable. Data collection was done by the researchers with the help of ten research assistants. Aggregate score was used to answer research questions 1 to 3 while Pearson r was used to answer research questions 4 and 5 and critical probability table of Pearson r was used to take decision on the six null hypotheses at 0.05 level of significance. The findings showed among others that: teachers rated their school organizational culture to be good; teachers’ job performance is good and teachers have positive attitude to their work. Also, it was found that there is no significant relationship between school organization culture and teachers’ job performance; and no significant relationship between school organizational culture and teachers’ attitude to work. Based on the findings it was recommended that: School management and management of Anambra State post primary school service Commission should ensure improvement in secondary school culture in order that all the teachers would rate their school culture to be good without some rating it to be poor. It was also recommended that in- service training be organized for secondary school teachers through seminars, workshops and advance learning in order to ensure that all of the teachers have good job performance and positive attitude to work.

Published: October 2020

Aggressive behaviour is a serious malady to students, especially those in their adolescent stage. This study investigated the effect of Socio-cognitive skills training on aggressive secondary school adolescents in Anambra State, Nigeria. One research question guided the study and two null hypotheses tested at 0.05 level of significance. The design for the study is quasi-experimental, non-randomised pre-test and post-test, control group design. The population of the study was 323 senior secondary school adolescents with high aggressive behaviour in Anambra State. A sample size of 32 adolescents were purposively drawn from two schools with the highest number of adolescents with high aggressive behaviour and used for the study. Instrument for data collection was adopted from Buss-Perry Aggression Questionnaire (BPAQ). The internal consistency reliability coefficient for Nigeria sample is 0.80. The completed instruments were scored following the scoring instructions provided in the BPAQ manual. Mean scores were used to answer the research question, while the null hypotheses were tested using Analysis of Co-variance (ANCOVA). The norm of 70.25 provided in BPAQ guided the decision. The finding of the study revealed that socio-cognitive skills’ training was effective in reducing aggressive behaviour of secondary school adolescents. The findings further revealed that the difference in the effect of socio-cognitive skills training on aggressive secondary school adolescents was significant when compared with those in the control group. Based on the findings it was recommended that the practicing counsellors and therapists should adopt the use of the technique in managing aggressive behaviours of secondary school adolescents.

Igwebuike theology of Omenani and the missionary bifurcation of horizons
Authors: Kanu Ikechukwu Anthony
Published: October 2020

African theology points to the fact that every particular situation or context calls for a particular theological reflection, that is, if the theological reflection is to make meaning within that unique circumstance. It is within this context that Igwebuike theology of Omenani emerges in relation to the understanding of culture as the Seed of the Word of God, which already pre-existed in Africa even before the emergence of the Western missionaries. The purpose of adopting this idea of culture as the Seed of the Word of God is to enhance the reconciliation between the African and Christian/Western ’worldhoods’. This piece presented the African culture as an important element in evangelization in Africa, as it is the spirit that animates the African people. It, therefore, located the Seed of the Word of God in the Omenani (the law of the land) of the African people through which they were able to achieve holiness even before the advent of the gospel. It observed that the failures of the missionary enterprise were majorly because of their lack of openness to the African religion and culture. The purpose of this study is to bridge the bifurcation created by the missionaries between the Christian and African ‘worldhoods’. The theoretical framework employed in this research is the Igwebuike sympathetic and non-derogatory framework, which emphasizes evangelization with a sense of understanding.

To determine the grain size distribution and chemical characteristics of bottom surface sediments in shallow brackish lagoons, we studied sediment samples collected from the entire horizontal lake area and in vertical profiles from three stations in Lakes Youngrang and Hwajinpo, on the eastern coast of Korea. Vertical and horizontal grain size distributions of the bottom sediments indicated predominantly sand- and silt in both lakes. The vertical distribution of C/N ratios ranged from 6.14 to 11.92 in Lake Youngrang, and 6.74 to 12.34 in Lake Hwajinpo. The horizontal distribution of C/N ratios in Lake Youngrang ranged from 6.1 to 17.6, whereas they ranged from 4.4 to 12.1 in Lake Hwajinpo. C/N ratios showed locally different responses to the origin of allochthonous (partial region) and autochthonous (entire region) organic materials. Horizontally, bottom sediment with low δ13C and high δ15N in Lake Youngrang were likely to be influenced by autochthonous organic material derived from primary production, and would be affected by N inputs from sources. In contrast, high δ13C and low δ15N sediments in Lake Hwajinpo were likely to be influenced by cyanobacteria.

This study investigated on how well the students can explain science concepts through movie scene clips as a summative assessment. It focused on the depth of the concepts learned in physics, chemistry, and earth and life science, and to the 21st century skills developed by the students while combining the scene clips and reviewing the concepts observed from the scenes.  Ninety seven students from three different schools in Luzon, Philippines during the first semester of school year 2017-2018 were selected to participate: grade 12 students under the Science, Technology, Engineering, and Mathematics strand enrolled in General Physics 1 from Pamantasan ng Lungsod ng Maynila, second year college students enrolled in General Chemistry from Bataan Peninsula State University and grade 11 students under the General Academic Strand  enrolled in Earth and Life Science from Isaac Lopez Integrated School in  Mandaluyong City. Students grouped in 4-5 members were required to choose a film and clip the scenes which have applications and violations of science concepts observed from the scenes. The outcomes were then presented in class. The result reveals a 3.1 mean in the students’ mastery of the concepts in physics, 3.0 mean in chemistry, and 3.2 in earth and life science, with 4.0 as the basis of an excellent mark. This shows that the mastery of the concepts learned in each subject falls under the proficient category. The study has also found support in the development of the students’ 21st century skills, which are creativity, teamwork, communication, critical thinking, digital competencies, leadership, and planning.
Incorporating Systemic Functional Linguistics in the Unlock English Teaching Program
Authors: Ishnaiwer Mohamed
Published: October 2020

This research attempts to develop a supplementary writing teaching method that is compatible with the Unlock intermediate level students at Birzeit University. The purpose of the study is to also provide writing instruction regarding four general writing needs and for such students: understanding genre, using clause and sentence structure for chosen text types, developing a sense of audience, and writing coherently. The study is based on the framework of Systemic Functional Linguistics (SFL), and the writing instruction is provided through two teaching methodologies, Joint Construction and the Logical Tree. The sample of this study is 54 intermediate-level students of the Unlock program, 27 of whom comprised the control group, the remaining 27, the experimental group. Frequency tables were utilized to calculate the sum of the cohesive and structural devices used. Overall, the results revealed more use of the measured variables in the experimental group than in the control. In the experimental group, devices of nominalization, contrast, addition, reason, register, and voice were used 115, 34, 27, 49, 92, and 27 times, respectively. However, in the control group, the same devices were used 58, 19, 11, 19, 35, and 12 times, respectively. The researcher recommends further research be conducted on larger samples of different levels of English proficiency in order to identify additional needs and provide a more representative assessment.
The scientific legacy of Juan A. Torres-Negrón
Authors: Lugo Ariel E.
Published: October 2020

Juan A. Torres-Negron (Juan Torres) studied ants, wasps, termites and other insect groups. I reviewed 34 of his publications and grouped them into six subjects: ecological theory, taxonomy, chemistry, ecology, synthesis, and commentaries. Juan Torres used empirical fieldwork, keen observations, and experimentation to advance the understanding of ant taxonomy and ecology in Puerto Rico. His taxonomic work involved the description of new species and genera of various insect groups, as well as revisions of taxonomic groups, and other observations of the ecology and behavior of rare taxa. Juan Torres also published several taxonomic keys in English and Spanish for various insect groups and localities. His work with ant communities advanced ecological niche theory and island biogeography highlighting the non-equilibrium and stochastic nature of ant community dynamics in Puerto Rico and adjacent islands. He also published synthesis summaries of the ants of Puerto Rico, Mona Island, and the Luquillo Mountains. His ecological studies of ants ranged from descriptions of biotic interactions among ants and with other animal species, to the quantification of the role of insects in wood decomposition and nutrient cycling. The research spanned from dry to wet forest and non-forest conditions in Puerto Rico and adjacent islands and cays.

Se realizaron 12 experimentos de campo en cuatro localidades (tres en cada sitio) con las variedades de caña de azúcar PR 980, PR 1059, PR 1016, PR 1028, PR 1048 y B 37-172. En cada localidad se sembró un experimento siguiendo un diseño de bloques al azar, en enero, otro en marzo y otro en mayo. En cada experimento, la caña se cosechó a los 12 meses de edad. Los datos de plantilla y retoño de cada experimento se analizaron conjuntamente, sin considerar las variaciones atribuidas a la localidad. La cosecha de marzo produjo los rendimientos máximos de sacarosa para la plantilla de PR 980, PR 1059 y B 37-117. El retoño de PR 1016 cosechado en marzo, produjo más azúcar que cuando se cosechó en enero. También se obtuvieron valores más altos para sacarosa en marzo que en enero para la variedad B 37-172. El análisis estadístico combinado para la plantilla y el retoño demuestra que a los 12 meses de edad las variedades PR 980, PR 1059, PR 1048 y B 37-172 producen más sacarosa si se cosechan en marzo que si se cosechan en enero.

En el primer ciclo de un programa de evaluación de variedades de pimiento de 1970 a 1973 se evaluaron 10 variedades (8 del tipo campana y 2 del tipo largo), en siembras mensuales en diferentes épocas. En unas se sembró la semilla directamente en el campo y en otras plantitas de semilleros. Los meses de noviembre a abril son los mejores para la siembra directa de pimiento en la zona noroeste. Junio es el mejor mes para la siembra por trasplante. En el segundo ciclo se evaluaron cuatro variedades de pimiento seleccionadas por sus altos rendimientos, resistencia a enfermedades y preferencias del consumidor. En este ciclo de siembras se lograron los rendimientos más elevados durante los meses de octubre, diciembre y febrero. Las variedades Blanco del País y Puerto Rico Wonder superaron en rendimientos a la Yolo Wonder Y y a la Cubanelle. Las siembras del segundo ciclo (cada 2 meses) confirmaron los resultados del primer ciclo. En el análisis combinado de todas las siembras, las variedades Puerto Rico Wonder y Blanco del País, la primera de las cuales fue desarrollada por la Estación hace muchos años, superaron a las otras ocho variedades en rendimiento. Se confirmó que estas dos variedades se adaptan bien a la región noroeste de Puerto Rico y que pueden producir buenas cosechas aún bajo condiciones adversas para otras variedades. En términos generales, se obtuvieron mejores rendimientos cuando la semilla se sembró directamente en el campo que cuando se trasplantó. En la siembra directa las plantas se desarrollaron más rápidamente, lográndose así una cosecha inicial más temprana.
