University English Teachers’ Challenges in Handling Unmotivated Learners: A Case Study

This exploratory case study investigated three university teachers’ views about their students’ unmotivation, the combination of amotivation and demotivation, in General English (GE) classes and explored challenges these teachers faced as written in their reflections during six semesters, from the second semester of the 2016/2017 academic year to the first semester of 2019/2020. The study used secondary document analysis with the teachers’ reflections analyzed using thematic analysis per the purposes of the study. The study found that teachers generally perceived many of their students to be unmotivated. It could be seen from their passive, reticent, and not attentive behaviours in class. They also reported the widespread phenomenon of absenteeism among learners. These teachers faced complex challenges in dealing with unmotivated students. These challenges were attributed to various intertwining factors within the instruction such as unreliable assessment, fun, yet not very meaningful class activities, and learners’ low proficiency level, as well as GE programme's position that seemed to be second-prioritized in learners' respective departments' curriculum. Though this case study may be unique in its context, a certain extent of replication in other contexts is possible. Suggested future studies include a more thorough investigation about the quality of assessment in English for non-English department’s students’ classes as well as a large-scale survey about absenteeism phenomenon in GE classes among non-English major students.

Preparation of high efficiency Cu2ZnSn(S,Se)4solar cells based on a single-step sulfo-selenization process

Cu2ZnSn(S,Se)4 (CZTSSe) kesterite semiconductors have been proposed as a potential medium to long term replacement of Cu(In,Ga)(S,Se)2 (CIGS) chalcopyrites for sustainable cost-efficient thin film technologies compatible with mass deployment at Terawatt level, being only constituted by elements abundant in the earth crust in contrast with the scarce Indium in CIGS. In this thesis, high efficiency CZTSSe solar cells were fabricated based on a single-step sulfo-selenization process. CZTSSe absorbers with optimal S/(S+Se) ratio, minimized Zn(S,Se) secondary phases in the interfaces, and good crystal quality were achieved through systematically fine tuning of various processing parameters during thermal treatments. The thermodynamic equilibrium of the single-step sulfo-selenization process was also analysed to elucidate the impact of different parameters on the thin films S/(S+Se) ratio. Besides, to address the big challenge of secondary phases in CZTSSe solar cells, an innovative (NH4)2S etching was developed for the selective and effective removal of Sn-(S,Se) secondary phases. This (NH4)2S etching can also passivate the absorber surface and a passivation mechanism was proposed to explain this behaviour. To further improve the efficiency of the CZTSSe solar cells, the CZTSSe/CdS interface was focused and engineered. Na spatial distribution in the CZTSSe/CdS interface region was optimized by a post low temperature treatment process (PLTT), leading to considerable enhancement of the performance of CZTSSe solar cells. An innovative Na dynamics model was established to illustrate the Na in-depth profiles. In addition, Cu doped CdS was investigated to reduce the thickness of CdS while keeping the comparable performance of the kesterite devices, which provides new possibilities to address the Cd concern. Finally, to suppress the CZTSSe/CdS interface recombination and reduce the Voc deficit of the CZTSSe solar cells, a facile wet chemical route based on AlCl3/GaCl3 + thioacetamide solutions were developed. The Voc and efficiency improvement after the chemical treatments can be mainly ascribed to the decrease of interface recombination and shunt paths. A champion CZTSSe solar cell with 9.1% efficiency and FF over 69% was achieved after all these processing optimizations (no ARC). This demonstrates that the single-step sulfo-selenization methodology is promising and feasible for obtaining high efficiency CZTSSe solar cells.
Nematoregulatory Effect in Industrial Banana Plantations of Service Plants, Crotalaria retusa, Cajanus cajan, Brachiaria decumbens and Panicum maximum in Fallow Land in the South Comoé Region of Côte d’Ivoire

Aims: In the context of promoting alternative cropping systems with less chemical inputs, studies on the introduction of service plants to reduce pesticide use are a major research effort. The pest caused by plant parasitic nematodes is a major constraint in banana cultivation. One of the main alternatives to the use of chemical nematicides is the rational use of service plants with nematoregulatory properties in crop rotation. Original Research Article Yeo et al.; IJPSS, 32(17): 11-19, 2020; Article no.IJPSS. 63153 12 Study Design: The experiment was carried out following Complete randomized design (CRD) with three replications. Place and Duration of Study: In industrial banana plantations located in the town of Ayamé, 40 km from the town of Aboisso in the forest area of southeast Côte d’Ivoire, between March to October 2016. Methodology: Among the candidate species, Crotalaria retusa, cajanus cajanus, Brachiaria decumbens and Panicum maximum were evaluated because of their nematoregulatory ability, promoting better sanitation of banana plots infested with nematodes. The experiment tested the behaviour of four service plant species in the field over a period of 8 months during a banana fallow (Musa spp.) populated by nematodes (Radopholus similis, Pratylenchus coffeae, Helicotylenchus multicinctus and Meloidogyne spp.). Results: The results obtained showed that all the service plants used had a purifying effect on nematodes except Cajanus cajan. Soil and root analyses of host plants show the nematoregulatory action of Crotalaria retusa, Cajanus cajan, Brachiaria decumbens and Panicum maximum by reducing the number of nematodes after 8 months of fallow. Fallows of poacea are the ones that reduce the most Radopholus similis and Pratylenchus coffeae rates. A reduction in the length of fallow time was also noted. Conclusion: This research has made it possible to improve the management of banana fallow land. This will ultimately help to define, under Côte d'Ivoire environmental conditions, a permanent living cover in association and/or rotation with the banana tree, in order to sustainably improve banana cultivation.

Caractérisation des propriétés biochimiques et nutritionnelles de la pulpe de baobab des espèces endémiques de Madagascar et d'Afrique continentale en vue de leur valorisation

Le baobab est un arbre qui pousse a l'etat sauvage en Afrique et ailleurs dans le monde ou le fruit est consomme sous differentes formes. Si l'ecologie et la botanique de la plante ont ete bien etudiees, il y a peu d'information disponible sur la composition biochimique d'une maniere generale et meme inexistante chez les especes malgaches en particulier. Cette etude s'inscrit dans le contexte du developpement et de la valorisation des produits locaux en Afrique. Elle a pour objectif principal de mieux caracteriser la pulpe des fruits de baobabs issus d'echantillons de diverses provenances de Madagascar et d'Afrique. A cette fin, elle s'est attachee dans un premier temps a caracteriser et a quantifier les principaux elements nutritifs comme les glucides, les acides amines, les lipides, les polyphenols, la vitamine C, les acides organiques, les elements mineraux et les aromes. La caracterisation biochimique de la pulpe a revele une forte acidite titrable (102 meq/100g), une teneur elevee en acide ascorbique (jusqu'a 312 mg/100g) et en polyphenols de 60,24 a 137,81mg/100g ainsi qu'un potentiel antioxydant tres fort de 329 a 1705,98 mg/100g et une bonne source de Ca de 658 mg/100g. Une evaluation du potentiel de ce fruit pour une valorisation a plus grande echelle a travers une amelioration des procedes de transformation existant en Afrique a ete realisee. L'identification d'une approche de stabilisation et de conservation du nectar par voie conventionnelle (pasteurisation) a ete realisee. Nos resultats ont montre que le nectar est aussi nutritif que les fruits usuels et que sa stabilisation peut se faire par une pasteurisation en utilisant le bareme 70°C/10 min. L'analyse sensorielle du nectar apres chaque etape de traitement (pasteurisation ; conservation 42 j) n'a pas montre de modification organoleptique du produit quelque soit les conditions utilisees. Deux approches empiriques classiques (modeles d'Arrhenius et de Ball) ont ete utilises pour decrire la cinetique de degradation thermique de la vitamine C du nectar. Enfin, une etude de faisabilite de l'utilisation de la spectrometrie proche infrarouge pour la caracterisation des origines et pour la determination des teneurs en constituants biochimiques a ete realisee. Ce travail a permis de montrer qu'il etait possible de doser la matiere seche, les proteines, le fructose et le potassium. Une separation des especes basee sur l'analyse des spectres semble aussi pouvoir etre realisee via leur appartenance aux sections (brevetubae, longitubae). (Resume d'auteur)
Reducing Voluntary Turnover through Career Development: Strategic HRD Research Proposal

137 Website: http://www.ijbmr. forexjournal.co.in Reducing Voluntary Turnover through Career Development ░ ABSTRACT: Voluntary employee turnover in the United States continues to spiral out of control and is expected to steadily increase in the coming years. Annual cost to American businesses exceeded $630 billion and is expected to exceed $700 billion within the next 24 months. The reasons for the sharp increase in voluntary turnover are not generational by nature as employees of all generations seek a connection with their employer and the ability to share in the firm’s growth. The reasons expressed by employers and employees include lack of training, weak relationships with managers and a general disconnect from company strategy. The primary reason given in recent years is lack of career development. Scheduled, agenda-driven discussions between senior leadership and the employee is needed to focus on employee skills, capacity for learning and enterprise goals has shown promise in reducing voluntary turnover, increasing employee engagement, and increasing talent depth in medium and large businesses. Career planning and development is not necessarily transactional as it includes specific training for a specific purpose to fit the firm’s strategic objectives. This approach can be used for lateral and vertical movement within the company. This proposal seeks to bridge the gap between existing literatures, current human capital management practices and move the discussion to a level that benefits employees and employers alike.
Formation of acrylamide in potato products and its dietary exposure

Acrylamide is formed during baking and frying of potato and cereal foodstuffs and is considered as a suspected human carcinogen. Potatoes are particularly susceptible to the formation of this process contaminant. Due to their frequent consumption, these products moreover contribute significantly to the dietary acrylamide exposure. Therefore, this study focuses on these foodstuffs. The Maillard reaction plays a key role in the formation of acrylamide. This reaction also contributes to the pleasant sensory characteristics of deep-fried potatoes, such as colour, taste and odour. Consequently, treatments which lower the formation of acrylamide also have, to a certain extent, an impact on the final product quality. A multifactorial approach is thus required to lower acrylamide contamination without losing the attractive and specific product characteristics. In this work, the impact and importance of different process-bound factors during the formation of acrylamide were investigated. An integrated research methodology was applied, starting from the pre-treatment of the raw material, through well-controlled and repeatable heating experiments, and ending with an accurate determination of acrylamide in the heated samples by means of LC-MS/MS. The proposed research shows that the type and the degree of deep-frying oil degradation did not significantly influence the formation of acrylamide, in contrast with the amount of oil and water present in the food matrix. Besides, it was shown that the link between acrylamide formation and French fry colour was sensitive to, among other things, the glucose/fructose ratio in the potato. This hinders a univocal prediction of the acrylamide contamination based on the product colour. Furthermore, acrylamide could be significantly reduced upon addition of specific amino acids, acids and salts. The impact of these additives on the sensory quality of the final product was assessed as well. The components and concentration levels had to be applied judiciously in order not to generate undesired product taste or colour. Finally, a probabilistic exposure assessment was performed under a population of faculty personnel and students. Biscuits, French fries, bread and chocolate were the most important sources of acrylamide intake. A nutritionally balanced diet with a lot of fruit and vegetables could possibly contribute to a lowered exposure to acrylamide.
Genome-wide scans for signatures of selection in Mangalarga Marchador horses using high-throughput SNP genotyping

Background The detection of signatures of selection in genomic regions provides insights into the evolutionary process, enabling discoveries regarding complex phenotypic traits. In this research, we focused on identifying genomic regions affected by different selection pressures, mainly highlighting the recent positive selection, as well as understanding the candidate genes and functional pathways associated with the signatures of selection in the Mangalarga Marchador genome. Besides, we seek to direct the discussion about genes and traits of importance in this breed, especially traits related to the type and quality of gait, temperament, conformation, and locomotor system. Results Three different methods were used to search for signals of selection: Tajima’s D (TD), the integrated haplotype score (iHS), and runs of homozygosity (ROH). The samples were composed of males ( n = 62) and females ( n = 130) that were initially chosen considering well-defined phenotypes for gait: picada ( n = 86) and batida ( n = 106). All horses were genotyped using a 670 k Axiom® Equine Genotyping Array ​ (Axiom MNEC670). In total, 27, 104 (chosen), and 38 candidate genes were observed within the signatures of selection identified in TD, iHS, and ROH analyses, respectively. The genes are acting in essential biological processes. The enrichment analysis highlighted the following functions: anterior/posterior pattern for the set of genes ( GLI3, HOXC9, HOXC6, HOXC5, HOXC4, HOXC13, HOXC11 , and HOXC10 ); limb morphogenesis, skeletal system, proximal/distal pattern formation, JUN kinase activity ( CCL19 and MAP3K6 ); and muscle stretch response ( MAPK14 ). Other candidate genes were associated with energy metabolism, bronchodilator response, NADH regeneration, reproduction, keratinization, and the immunological system. Conclusions Our findings revealed evidence of signatures of selection in the MM breed that encompass genes acting on athletic performance, limb development, and energy to muscle activity, with the particular involvement of the HOX family genes. The genome of MM is marked by recent positive selection. However, Tajima’s D and iHS results point also to the presence of balancing selection in specific regions of the genome.
Vapor–Dissociation–Solid Growth of Three-Dimensional Graphite-like Capsules with Delicate Morphology and Atomic-level Thickness Control

Two-dimensional graphene is easy to aggregate and hard to transfer because of the van der Waals forces between graphene layers. The three-dimensional (3D) graphite-like capsules (GCs) disperse well and exhibit robust structural stability and have a potential for promising applications in energy storage, drug delivery, catalyst substrate, etc. Here, we develop a catalytic chemical vapor deposition route for the synthesis of 3D GCs with unprecedented thickness and morphology control. The theoretical results indicate that the strong chemisorption and charge transfer between ZnO and acetylene allow the layer-by-layer formation of GCs that is later confirmed by the experimental data. The 3D GCs are synthesized with thickness control from three atomic layers to ∼300 atomic layers over various oxides with predesigned shapes of microscale tetrapods, nanospheres, nanorods, nanocubes, etc. In particular, the formation mechanism of GCs is investigated using the ZnO surface as a catalyst through systematically experi.
