Published: July 2019

ABSTRAK Paper ini membahas tentang simulasi dan pembuatan rangkaian sistem kontrol pengisian baterai yang bersumber dari sebuah pembangkit listrik tenaga surya (Panel Surya). Pengisian baterai yang terlalu lama pada sebuah instalasi pembangkit listrik tenaga surya akan menyebabkan baterai cepat rusak sehingga dibutuhkan sebuah sistem yang dapat berfungsi sebagai pengontrol. Metode penelitian yang dilakukan yaitu dengan merangkai rangkaian yang didapat dari pustaka kemudian disimulasikan dengan perangkat lunak Proteus ISIS Profesional, selanjutnya dilakukan pembuatan rangkaian elektronika dalam sebuah PCB. Tegangan yang dihasilkan oleh baterai dibaca oleh sistem kontrol kemudian sistem akan memilih apabila tegangan yang diberikan oleh panel surya akan diisi pada baterai atau dialihkan kepada sebuah beban tambahan. Hasil yang didapatkan dalam penelitian menunjukan bahwa sistem kontrol pengisian baterai yang dibangun telah bekerja sesuai dengan simulasi dan dapat bekerja dengan baik. Kata-kata kunci: sistem kontrol baterai, switch, panel surya. SIMULATION AND CONSTRUCTION OF A BATTERY CHARGING CONTROLLER SYSTEM FOR SOLAR POWER PLANTS ABSTRACT This paper discusses about circuit simulation and construction of a battery charging control system from a solar power plant (Solar Panels). Charging the battery for too long on an installation of solar power plants will cause the battery to be broken and so we need a system that can function as a controller. The research method is made by simulating a baterry charging control circuit from a reference and then simulated by Proteus ISIS Professional software, then constructing the circuit on a PCB. The voltage produced by the solar panel is read by the control system then the system will prefer if the voltage supplied by the solar panels will be filled on the battery or transferred to an additional load. Result obtained in this study indicate that the baterry charging control system are working in accordance with the software simulation and can work as a baterry charging control system for a solar panel instalation. Keywords: Baterry charging control, switch, solar panel.

Published: July 2019

Long noncoding RNAs (lncRNAs) participate in and regulate the biological process of colorectal cancer (CRC) progression. Our previous research identified differentially expressed lncRNAs in 10 CRC tissues and 10 matched nontumor tissues by next-generation sequencing (NGS). In this study,
we identified an lncRNA, FEZF1 antisense RNA 1 (FEZF1-AS1), and further explored its function and mechanism in CRC. We verified that FEZF1-AS1 is highly expressed in CRC tissues and cell lines. Through functional experiments, we found that reduced levels of FEZF1-AS1 significantly suppressed
CRC cell migration, invasion, and proliferation and inhibited tumor growth in vivo. Mechanistically, we discovered that reduced levels of the lncRNA FEZF1-AS1 inhibited the activation of epithelial‐mesenchymal transition (EMT); the overexpression of orthodenticle homeobox 1 (OTX1) partially
rescued the FEZF1-AS1-induced inhibition of protein expression. It indicated that FEZF1-AS1 may play a role in the occurrence and development of CRC by regulating the FEZF1-AS1/OTX1/EMT pathway. Furthermore, it was reported that FEZF1-AS1 is located in both the nucleus and cytoplasm of HCT116
cells. Dual-luciferase reporter assays verified that FEZF1-AS1 directly binds miR-30a-5p and negatively regulated each other. Further, we showed that 5′-nucleotidase ecto (NT5E) is a direct target of miR-30a-5p, and the inhibition of miR-30a-5p expression partially rescued the inhibitory
effect of FEZF1-AS1 on NT5E. Our results indicated that the mechanism by which FEZF1-AS1 positively regulates the expression of NT5E is through sponging miR-30a-5p. Our study demonstrated that lncRNA FEZF1-AS1 is involved in the development of CRC and may serve as a diagnostic and therapeutic
target for CRC patients.

Published: July 2019

Photocatalysis is considered to be a promising technique for the degradation of organic pollutants. Herein, a 0D/1D composite photocatalyst consisting of Au nanoparticles (NPs) and CuBi2O4 microrods (Au/CBO) was designed and prepared by a simple thermal reduction–precipitation approach. It shows excellent photocatalytic performance in the degradation of tetracycline (TC). The maximum photocatalytic degradation rate constant for Au/CBO composites with 2.5 wt % Au NPs was 4.76 times as high as that of bare CBO microrods. Additionally, the 0D/1D Au/CBO composite also exhibited ideal stability. The significant improvement of the photocatalytic performance could be attributed to the improved light harvesting and increased specific surface area, enhancing photoresponse and providing more active sites. Our work shows a possible design of efficient photocatalysts for environmental remediation.

The need for scientists to exchange, share, and organise data has resulted in a proliferation of research data portals in the past decades. These cyberinfrastructures have had a major impact on taxonomy and helped to revitalise the discipline, by allowing quick access to bibliographic information, biological and nomenclatural data, and specimen information. In addition, several specialised portals aggregate particular data types for a large number of species and can be queried to extract information for a particular taxonomic group. Because of their ecological and economic importance, several early initiatives to develop and deploy information technologies for capturing, sharing, and disseminating information focused specifically on the plant family Leguminosae (Fabaceae). Initiatives such as ILDIS (International Legume Database and Information Service), which was created in 1985, led the way in developing methods and thinking with regard to taxonomic data management more generally. More recently, the Legume Phylogeny Working Group (LPWG) was founded in 2010 with the objective of facilitating collaboration amongst systematists working on the plant family Leguminosae (Fabaceae). As part of this endeavour, the LPWG has explored whether it would be desirable and pertinent to develop a new portal focused on the legume family. We argue that, despite access to numerous data aggregation portals, a taxon-focussed portal curated by a community of researchers specialised on a particular taxonomic group, such as the LPWG, have the interest, commitment, existing collaborative links, and knowledge necessary to verify data quality, thereby providing a valuable resource and actively contributing to other more general data providers. We consider that a new portal focused on Leguminosae would thus serve a useful function in parallel to and different from large international data-aggregation portals. We explored best practices for developing a legume-focused portal that will enable long-term sustainability, data sharing, a better understanding of what data are available, missing, or erroneous, and ultimately facilitate cross analyses and development of novel research. We surveyed existing data portals to see what features are of interest to our goal and we present a general way forward for developing a legume-focused portal that would respond to the needs of the legume systematics research community as well as to the broader user community. We propose to take full advantage of existing data sources, informatics tools, and protocols to develop an easily manageable, scalable, and interactive portal that will be used, contributed to, and fully endorsed and supported by the legume systematics community.
Supporting Essential Biodiversity Variables: The GLOBIS case study
Authors: Belbin Lee , Hobern Donald
Published: July 2019

Essential Biodiversity Variables (EBVs) are the latest push toward supporting state of the environment indicators (Pereira et al. 2013). The European Union Funded Creative-B Project (see https://cordis.europa.eu/project/rcn/100345/brief/en) outlined the status and strategy for interoperability between what they termed Biodiversity Research Infrastructures (BRIs: such as the Global Biodiversity Information Infrastructure (GBIF), the Atlas of Living Australia (ALA) and the Integrated Digitized Biocollections (iDigBio)). Toward the end of that project, the group decided that a logical follow-on project should position BRIs to support the production of Essential Biodiversity Variables (EBVs). This idea became the GLOBal Infrastructures for Supporting Biodiversity research (GLOBIS-B) project (http://www.globis-b.eu) and this presentation provides a summary of a case study on generating EBVs (Hardisty et al. 2019).

As a part of GLOBIS-B, I suggested that a small team of GLOBIS members should document in detail, each step in the production of an EBV from GBIF and the ALA data for a few invasive species. We wanted address the rarity of detailed recording and justification for each step in the production of a dataset for environmental evaluation. I anticipated that the team would encounter many practical issues, but this case study raised far more significant issues that any of us had anticipated.

The EBV chosen for this study was Area of Occupancy (IUCN Standards and Petitions Subcommittee 2017) and the species selected represented various invasion scenarios: Acacia longifolia; Vespula germanica and Bubulcus ibis. The workflow included 20 steps between locating data and publishing an EBV, and these steps were radically different between GBIF and the ALA. The workflow required manual steps such as resolving invasive status of Acacia longifolia subspecies; only one of which was ‘invasive’. Datasets of occurrence records had to be exported from the ALA and GBIF to enable filtering for purpose, for example, not all Darwin Core terms are exposed in the current public interface of the ALA. After the record filtering, the ALA and GBIF datasets then required merging and deduplication, for which one-off code had to be written.

A few of the 15 significant messages from this study included: a lack of consistency of data between BRIs (e.g., GBIF records should be a superset of ALA records); consistency and adequacy of filtering tools between BRIs; exported data structures massively differed between BRIs; that automation of the workflows may be possible but many manual intervention steps were required. By my figuring, the case study took approximately 10 times longer than anticipated, but the messages to BRIs was clear – consistency and adequacy of data and tools require urgent work.
Regards des professionnels de santé en soins palliatifs sur la spiritualité : une étude qualitative
Authors: Cuniah Maeva , Bailly Nathalie , Bréchon Geneviève
Published: July 2019

Cette étude qualitative s’est attachée à décrire les représentations des professionnels vis-à-vis du concept de spiritualité afin de mieux cerner son intégration dans l’accompagnement. La méthodologie retenue repose sur l’organisation de deux focus groups pluriprofessionnels (en institution et au domicile), adjoignant chacun 6 professionnels impliqués dans l’accompagnement en soins palliatifs (2 médecins, 5 infirmiers, 3 aides-soignants, 1 psychologue et 1 interne). Une analyse de contenu a permis de mettre en évidence trois thèmes pivots émanant des focus groups : les représentations de la spiritualité des professionnels ; la place qu’elle occupe dans leur pratique et leurs attentes en matière d’accompagnement spirituel. De par le caractère polysémique qu’elle revêt, la spiritualité est un concept difficile à aborder lors de la rencontre avec le patient pour les professionnels. Cependant, tous soulignent l’importance d’assurer un accompagnement global de la personne en tenant compte de l’ensemble des dimensions de la personne, y compris spirituelle et ce, qu’elle soit religieuse ou non. Proposer à l’autre un espace, une présence, une écoute à cette dimension, si la demande s’en fait sentir, ce sont des attitudes que tendent à suivre les professionnels pour éclairer le cheminement personnel des patients et la mise en sens de ce qu’ils traversent.

Un établissement pénitentiaire singulier dans «l’archipel punitif» de l’armée française en Algérie : L’établissement des fers de Douera puis de Bône (1855-1858)
Authors: Biskri Nadia
Published: July 2019

Au printemps 1855, un établissement pénitentiaire pour des soldats et marins condamnés à la peine des fers est installé en Algérie, dans le camp militaire de Douera puis dans la forteresse de Bône. Sa création résulte de la nouvelle politique pénitentiaire mise en œuvre par le Second Empire fondée sur le peuplement colonial par les mauvais sujets, rejetés hors du territoire métropolitain. Bien que son existence ne perdure pas au-delà de trois années, ce lieu de punition pour les déviants à l’ordre militaire se révèle pour l’historien un véritable observatoire d’une expérimentation pénitentiaire singulière en situation coloniale. Unique au sein des structures punitives de l’armée française en Algérie, l’établissement des fers de Douera/Bône, témoigne de la perméabilité des systèmes carcéraux civil et militaire dans un contexte de vif conflit de compétences entre l’autorité militaire et l’administration civile. Les discours et pratiques carcérales à l’égard des condamnés aux fers permettent de saisir la double conception punitive et pénitentielle de la prison tenue de châtier autant que d’amender les militaires dégradés tout en servant les intérêts de la colonisation par la mise au travail forcé.

Cet article revient sur les séjours en captivité qui ont jalonné l’histoire politique de Habib Bourguiba. Inscrits à la fois dans une géographie du pouvoir colonial – des pénitenciers du sud au nord de la Tunisie, des prisons militaires aux résidences surveillées en métropole –, dans l’histoire de la Seconde Guerre mondiale, et dans la période de l’avènement de l’indépendance, ces jalons sont autant de chapitres de l’histoire du mouvement national tunisien souvent recomposés. Cet article étudie comment s’est composée la figure du zaïm (leader) au cours de ces années de détention, et comment la prison est devenue un lieu de mémoire du bourguibisme.

Objetivo: Identificar a eficácia do hipoclorito de sódio e do álcool a 70% na desinfecção de superfícies. Método: Revisão integrativa em bases/bancos de dados: Biblioteca Nacional de Medicina dos Estados Unidos (PUBMED); Scientific Electronic Library Online (SCIELO); Latin American and Caribbean Health Science Literature Database (LILACS) e Web of Science. A busca foi realizada em documentos publicados entre 2008 e 2017. Foram utilizados os seguintes descritores controlados e combinados, em português, inglês e espanhol: Eficácia, Etanol, Hipoclorito de Sódio, Desinfecção e Serviços de Saúde. Foram selecionados para compor a amostra seis artigos. Desses, 66,6% apresentaram forte nível de evidência. Resultados: Os resultados apontam maior eficácia do hipoclorito de sódio em relação ao álcool a 70%, na desinfecção de superfícies, principalmente pela sua ação microbicida e atuação nos esporos. A enfermagem se destacou em contribuir para um maior desenvolvimento nas pesquisas, sendo importante protagonista na evolução dos cuidados e na promoção da segurança dos pacientes e de trabalhadores da saúde. Conclusão: Embora os estudos incluídos tenham sido realizados em unidades hospitalares, destaca-se a importância da prevenção de disseminação de micro-organismos nos ambientes de cuidados primários de saúde, uma vez que o fenômeno de ocorrência de infecção independe do local onde a assistência é prestada.

Objetivo. Descrever o itinerário terapêutico de crianças quilombolas com doença falciforme. Método. Trata-se de um estudo descritivo-exploratório com abordagem qualitativa, realizado na comunidade quilombola de Praia Grande, na Ilha de Maré – BA, com mães de crianças quilombolas com doença falciforme, no período de julho a setembro de 2018. Como instrumento de coleta de informações, foram utilizados a entrevista semi-estruturada e ecomapa. A análise dos dados foi baseada no modelo interativo de análise de conteúdo de Miles e Hubermans. Resultados. Evidenciaram peregrinação das mães em busca de atendimento das crianças; a ausência de estrutura da rede assistencial, bem como a repercussão dessa doença na vida de mães, crianças e famílias. Considerações Finais. O itinerário terapêutico das crianças quilombolas com doença falciforme permeia por uma realidade de iniquidade e inadequação da rede de atenção à saúde da criança e um despreparo por parte dos profissionais de saúde para o cuidado. Evidencia-se a necessidade de articulação da rede e da capacitação profissional, tendo em vista a magnitude da doença falciforme.

Ademais gestantes com maior renda familiar não apresentaram baixa eficácia para o aleitamento materno e, das 75,24% que tinham ensino médio completo, 47,52% demonstraram alta eficácia. Conclusão: questões sociodemográficas, como renda e escolaridade, podem influenciar na autoeficácia materna, repercutindo na confiança da mulher no processo de amamentar. Evidenciou-se alta autoeficácia para o aleitamento no pré-natal, portanto, devem-se empregar estratégias que visem a manter elevada a autoeficácia materna, a fim de se promover a autoconfiança da mãe no pós-parto e reduzir risco de desmame precoce. As gestantes que foram identificadas com baixa eficácia para o aleitamento materno apresentaram maior risco de desmame precoce. Portanto, os profissionais de saúde e a família devem prover o suporte necessário para que elas sejam empoderadas em sua capacidade de amamentação no pós-parto.
Comercio informal en ciudades de frontera. Estudio de caso de los feriantes de ropa y calzado en la ciudad de Tacna (Perú)
Authors: Jiménez Palacios Ricardo
Published: July 2019

Las especificidades ocurridas en ciudades de fronteras, tales como los tipos de cambio, las dinámicas productivas o la subvención de servicios, se convierten en un factor importante para las diversas articulaciones socioeconómicas transfronterizas. De esta manera, la ropa y el calzado usados, cuya importación está permitida en el norte de Chile, pero prohibida en el territorio peruano, permite la consolidación de la Feria de Ropa y Calzado de Segundo Uso en la ciudad fronteriza de Tacna (Perú), la cual se convierte en un importante núcleo de desarrollo a nivel local. El presente artículo presenta las principales características de esta actividad por medio de un estudio cuantitativo que aborda aspectos sociales, económicos y de prejuicio en torno a este grupo de comerciantes.
América Latina frente a un cambio de época
Authors: Bernal-Meza Raúl
Published: July 2019

La reconciliación diplomática entre Estados Unidos y Cuba y la visita de Obama a La Habana constituyen un quiebre –político, ideológico, eidético y de paradigmas– que, siguiendo la argumentación de Hobsbawm sobre los períodos históricos del siglo XX, marcan un “cambio de época” en las relaciones internacionales hemisféricas, dando inicio a una reconfiguración cuyas tendencias están determinadas por los recientes recambios de gobierno en distintos países de América Latina y, fundamentalmente, por el proceso de transición hacia un nuevo orden de relaciones internacionales y hemisféricas que ha impulsado Donald Trump. En este contexto, lo nuevo, que representa el “cambio de época”, está determinado por el ejercicio del poder por parte de Estados Unidos, entre una praxis de poder social, de mayor multilateralismo, cuya mejor expresión fue la reconciliación diplomática entre Estados Unidos y Cuba, pero también por el retorno al unilateralismo, el proteccionismo y la interpretación de un poder norteamericano sin igual, por parte de Washington, bajo la administración del presidente Trump. El texto contribuye a la identificación del proceso de cambios –globales, hemisféricos y regionales– posteriores al “cambio de época” y al análisis sobre respuestas que están surgiendo en Sudamérica frente a los nuevos escenarios globales y regionales.
The point-of-care testing in the emergency department
Authors: Carraro Paolo
Published: July 2019

The decentralization of analysis at the emergency room is a well-established practice, in particular for the use of blood gas analysis. Recently, many other analyzers have been proposed, with rapid methods that can potentially reduce the response time of the tests. Here we consider the various analyzers that can be used at the bedside, their advantages and limits, the related scientific evidences. Finally, we discuss their impact both on patient care and on accelerating the patient’s flow in the emergency room.

Early recognition of myocardial infarction (MI) remains a challenge, especially in patients presenting with non-ST-segment elevation MI. Heart-type fatty acid binding protein (hFABP) has shown to be a more sensitive marker for myocardial necrosis as compared to non-high sensitive troponins (4th generation and older). However, since high sensitive troponin (hs TnT) assays are available, it is questionable whether hFABP still has value as a diagnostic tool for MI. A systematic search was conducted in Medline, Embase and Cochrane. After selecting the articles, they were assessed for risk of bias according to the QUADAS-2 criteria. Negative predictive value, positive predictive value, sensitivity and specificity were extracted or calculated if possible. Nine studies met the inclusion criteria. Overall, hs TnT showed higher sensitivity than hFABP, while hFABP had higher specificity. In patients presenting within 3 hours after onset of symptoms, sensitivity is low for both hFABP and hs TnT (19-63% vs 25-55%, respectively), while specificity seems higher for hFABP than for hs TnT (70-99% vs 57-86%, respectively). In these patients, the area under the curve for hs TnT is equal or better than that for hFABP (0.67-0.92 for hs TnT vs 0.69-0.85 for hFABP). The addition of hFABP to hs TnT did not improve sensitivity and specificity. This systematic review finds no advantage for using hFABP over hs TnT in either early presenting patients or overall. Furthermore, no advantage was found if a combination of hFABP and hs TnT was used for the diagnosis of MI.

SICKLE CELL DISEASE AND INFECTIONS IN HIGH- AND LOW-INCOME COUNTRIES
Authors: Cannas Giovanna
Published: July 2019

Infections, especially pneumococcal septicemia, meningitis, and Salmonella osteomyelitis, are a major cause of morbidity and mortality in patients with sickle cell disease (SCD). SCD increased susceptibility to infection, while infection leads to SCD-specific pathophysiological changes. The risk of infectious complications is highest in children with a palpable spleen before 6 months of age. Functional splenectomy, the results of repeated splenic infarctions, appears to be an important host-defense defect. Infection is the leading cause of death, particularly in less developed countries. Defective host-defense mechanisms enhance the risk of pneumococcal complications. Susceptibility to Salmonella infections can be explained at least in part by a similar mechanism. In high-income countries, the efficacy of the pneumococcal vaccine has been demonstrated in this disease. A decreased in infection incidence has been noted in SCD patients treated prophylactically with daily oral penicillin. Studies in low-income countries suggest the involvement of a different spectrum of etiological agents.
VIRAL LOAD AND NUCLEOTIDE SUBSTITUTIONS IN HEPATITIS B VIRUSES DERIVED FROM CHRONIC HBV PATIENTS
Authors: Shokatpour Narjes , Vaezjalali Maryam , Foster Graham R , Sali Shahnaz
Published: July 2019

Background: Mutations in the S gene (HBsAg), precore (PC) and basic core promoter (BCP) of the hepatitis B virus (HBV) are correlated with a wide spectrum of diseases. This study assessed the frequency of mutations in the S gene, PC and BCP regions in chronic hepatitis B (CHB) patients.

 

Methods: 104 CHB patients who visited Tehran Hepatitis centers, were included. The viral load of samples was determined based on the TaqMan method. Regions of the S gene, PC and BCP were amplified by the nested PCR. Positive PCR products were sequenced and analyzed.

 

Results: Successfully sequenced S gene region revealed all the derived strains were genotype D, with the majority (90%) belonging to the ayw2 subtype, and the rest (9%) to the ayw1 subtype. The prevalence of mutations was found to be 51% and 18% in the HBsAg and MHR regions, respectively. 70% of amino acid changes within HBsAg occurred in different immune epitopes, of which 27% and 72% were located in B cell and Th epitopes, respectively. Successfully sequenced PC and BCP regions showed at least one mutation in 84.6% of the patients. The PC and BCP mutations were G1896A (61%), G1899A (23%), A1762T/G1764A (23%) and G1764T/C1766G (26%). None of the strains with A1762T/G1764A mutation carried the G1764T/C1766G mutant.

 

Conclusions: Our results showed common mutations within HBsAg, occurring in immune epitopes, a high rate of G1896A mutations in the PC region, and a negative correlation between the emergence of A1762T/G1764A mutation and the G1764T/C1766G mutant in the BCP region.
An exploratory study of early career teachers as culturally responsive teachers
Authors: Beutel Denise Ann , Tangen Donna , Spooner-Lane Rebecca
Published: July 2019

The purpose of this study was to advance understanding on how early career teachers imagined themselves to be culturally responsive and how their beliefs and ideologies about teaching a diverse range of learners were challenged and refined during their early years of teaching. This qualitative, exploratory study was conducted in a large, secondary school in eastern Australia that has a highly diverse population of students. Findings indicate that, while these early career teachers lacked preparation for working with diverse learners,  building relationships on multiple levels (with students, with fellow beginning teachers, and with senior staff which includes ongoing support and mentoring from colleagues) is essential for the development of early career teachers as culturally responsive practitioners. Findings are discussed in relation to Garmon’s (2005) six key factors for teaching diverse groups of students: openness, self-awareness, commitment to social justice, having intercultural experiences, have support group experiences, and recognising individual growth.  These findings have implications for schooling systems in how they can better transition early career teachers to classrooms and for higher education teacher preparation programs in Australia and many other countries with a growing number migrant and refugee students coming into the school system.
Becoming College and Career Ready: Combating The New Digital Divide – A Literature Review
Authors: Orta Nelson A
Published: July 2019

The availability of technologies for supporting  personal, productivity, communications, and business tasks is ubiquitous and expected.  Educational systems have a significant responsibility to ensure future generations are skilled to assume job duties involving the pervasive use of digital assets.  Schools and higher education institutions, being at the epicenter of preparing the workforce for the adoption of technologies for learning and productivity, are increasingly making significant investments to develop digital skills among students. Given the increased adoption of technologies for instruction in U.S. classrooms, the digital divide as a concept may be shifting from lack of access, to a deeper context referred to understanding how to purposefully utilize technology to develop literacy, support academic growth, conduct research, and enhance productivity. There is evidence of significant skill gaps between students coming from high versus low socio-economic households, therefore, it is imperative to prioritize investments in technologies for learning and robust digital pedagogy practices in schools serving low socio-economic status students. This paper provides an updated definition of the digital divide and the importance of providing effective technology-based pedagogy to students from poverty to prevent skill gaps from becoming a competitive disadvantage as they strive to be successful in college and careers.
Assessment of Creative Thinking of Hong Kong Undergraduate Students Using the Torrance Tests of Creative Thinking
Authors: Ng Annie W. Y. , Lee Chung-Yee
Published: July 2019

Creativity has been a key graduate attribute and transferrable skill for the universities nowadays. A better understanding of freshmen students’ level of creativity thinking facilitates the cultivation of the ways for nurturing the development of creativity in students throughout their university education studies. The purpose of this study was to investigate creative thinking abilities of first-year undergraduates in Hong Kong using the Torrance Tests of Creativity Thinking (TTCT) – a commonly known assessment for creativity.  A total of 492 first-year undergraduates at a university in Hong Kong were asked to complete TTCT Figural Form consisting of picture construction, picture completion and lines activities. Generally, the creative potential of Hong Kong undergraduates was well above the average. The students demonstrated their abilities in generation of a number of relevant ideas (fluency), producing novel responses (originality), abstract thinking (abstractness of titles), and open-minded thinking (premature closure). They exhibited creative strength of, for example, flexible imagination, thinking with senses, and thinking beyond boundaries. However, students’ elaborative thinking, metaphorical-thinking and sense of humor had a lot of room for improvement. Based on the assessment results, some implications on the possible institutional strategies for nurturing creativity among students during university education were discussed.

Published: July 2019

Video tutorials are a useful tool that strengthens the face-to-face classes. This study focuses on the influence of videos on the perceptions of students in the subject Advanced Financial Transactions. The results of this analysis show a high level of learner satisfaction. They consider that videos help them to improve their learning outcome, since these reinforce the practical contents which have been previously taught in the master class. Videos allow students to be more proactive and autonomous in their learning. The findings support the relevance of integrating new educational tools in the university study programmes.
