Understanding how university student perceptions of resources affect technology acceptance in online learning courses
Authors: Sivo Stephen Anthony , Ku Cheng-Hsin , Acharya Parul
Published: March 2018

The purpose of this empirical research was to use the perceived resources and technology acceptance model (PRATAM; Ku, 2009) to observe and measure students’ beliefs on using the WebCT online learning system (OLS) in two WebCT courses offered at a large university in the south-eastern United States. PRATAM was replicated from previous research to address the factors of perceived resources (R), perceived usefulness (U), perceived ease of use (EOU), attitude towards using, behavioural intention to use (BI), and actual system use (USE). The results show that the constructs of PRATAM explained the data well in both surveys conducted. This study makes a contribution to the literature on PRATAM by identifying and understanding the factors that influence students’ behaviours in response to the OLS. Moreover, it provides insights for administrators and instructional designers for improving students’ persistence and retention in online learning courses.

Published: March 2018

This study aimed to investigate how the use of a smartphone clicker app by a group of 390 Saudi Arabian male undergraduate students would impact their learning performance while participating in a computer science class. The smartphone clicker app was used by the students during peer group discussions and to respond to teacher questions. A conceptual framework identified teacher-student and student-student interactions, collaborative learning, and student engagement as three primary practices that could improve student performance when a smartphone clicker app was used. The relationships between these factors were tested empirically by participant completion of a self-administered online survey. This study found the use of a smartphone clicker app promoted increased teacher-student and student-student interactivity, leading to active collaboration learning by students and improved learning performance. No positive relationship was found between the smartphone clicker app use and increased student engagement. These results demonstrated the role of the smartphone clicker app in enhancing the learning experience of the Saudi undergraduate students included in this study, but not the overall student engagement. Further research into how use of a smartphone clicker app in classroom settings might promote student engagement to improve the overall learning performance is needed.
User acceptance in a computer-supported collaborative learning (CSCL) environment with social network awareness (SNA) support
Authors: Lin Jian-Wei , Lin Hao-Chiang Koong
Published: March 2018

Although many e-learning studies have applied the unified theory of acceptance and usage of technology (UTAUT) to investigate user acceptance, their findings have been inconsistent. One of reasons is that the user acceptance model of an e-learning system can be determined by the new information technologies (or mechanisms) the e-learning system utilises. Computer-supported collaborative learning (CSCL) with social network awareness (SNA) mechanisms has been widely adopted because it can enhance online collaborative learning effectiveness. Since new SNA mechanisms are expected to have a huge impact on user acceptance in CSCL environments, this study extends UTAUT to investigate user acceptance of an SNA CSCL environment. This study empirically evaluated the extended model by surveying 186 undergraduates, who had completed a 5-week electric commerce course in an SNA CSCL environment. The findings indicated that the SNA mechanism substantially strengthened the effect of social influence on behavioural intention to use the SNA CSCL system. Compared with other CSCL studies, the predictive power of social influence in this study was higher, while that of other determinants (i.e., performance expectancy and effort expectancy) in this study were lower. The extended model demonstrated higher explanatory power compared to models used in other CSCL studies.

Published: March 2018

This article presents the results of a combined experimental and analytical/computational study of the transition from corrosion pits to stress corrosion cracks during the exposure of low-carbon steel to environments with different pH levels (pH of 3, 5, 8, and 11). The transition from pits to cracks is elucidated via confocal microscopy and scanning electron microscopy. The stress concentrations associated with possible pit sizes and configurations are also modeled using finite element analyses and fracture mechanics models. Finally, the implications of the results are discussed for the modeling of the transition from pitting to stress corrosion cracking in low-carbon steels.
Modeling the Emergence of Antibiotic Resistance in Bacterial Populations
Authors: Williams Michelle A. , Friedrichsen Patricia J. , D. Sadler Troy , Brown Pamela J. B.
Published: March 2018

Since antibiotics have become routinely used to treat infections, antibiotic resistance is now an emerging concern for public health. To understand how bacteria become resistant to antibiotics, many students draw from the common misconception that bacteria gain resistance upon antibiotic exposure. We have designed models and a corresponding lab that explores how a population of bacteria can evolve antibiotic resistance, with emphasis on dispelling common misconceptions surrounding the mechanism of antibiotic resistance. Using an antibiotic disk diffusion assay, students compare the antibiotic resistance level of a harmless E. coli strain of bacteria over time. Then, students compare their lab data to the models, which together illustrate the roles that initial genetic variation and random mutation play in the evolution of antibiotic resistance. In this guided investigation, basic microbiology concepts and techniques are made accessible to students in a high school classroom. The models developed here are in line with the practices of the Next Generation Science Standards (NGSS). The models, together with the lab, are used to guide students through the process of argumentation using a claim, evidence, and reasoning (CER) format to explain the evolutionary mechanisms of antibiotic resistance.

Abstract:

Introduction: The prevalence of pelvic organ prolapse (POP) with aging is escalating alarmingly, and now becoming a growing epidemic among the elderly. Synthetic transvaginal mesh (TVM) has been employed with increasing popularity in the treatment of POP until the end of the last decade. After the U.S. Drug and Food Administration (FDA) warnings in the years 2008 and 2011, the number of vaginal mesh operations has decreased dramatically. Aim: The aim of the study was to evaluate and compare the anti-POP effectivity, the anti-stress incontinence (anti-SUI) efficacy, and the late (36 months) post-operative complications of the anterior vaginoplasty and the TVM operations. Method: We analysed the clinical data from 120 patients with stage II–III anterior prolapse and concomitant SUI who had undergone surgery at a tertiary referral centre in Hungary between January 2013 and January 2014. Sixty patients underwent Kelly–Stoeckel vaginoplasty and the other 60 cases had TVM operation. The surgical complications were classified using the Clavien–Dindo (CD) classification system. Results: The anti-POP (91.6% vs. 63.3%; p<0.001) and the anti-SUI efficacy (90% vs. 55%, p<0.001) were significantly higher in the TVM group than in the vaginoplasty group, while the overall extrusion rate was found 8.3% after a 3-year follow-up. The Clavien–Dindo score (CD) proved that the early post-operative complication profile was similar among the TVM patients as compared to the vaginoplasty group (p = 0.405). Conclusion: Vaginal mesh surgery represents an effective procedure for prolapse and concomitant SUI with a decreased risk of short- and long-term complications. Orv Hetil. 2018; 159(10): 397–404.

Abstract:

Introduction: Lung cancer is the most common malignant tumor in Europe and Hungary. In 2010, 10 557 new cases were registered in Hungary; 80–85% of these cases were associated with smoking. Aim: In our work we analyzed the data of lung cancer patients of the last 15 years retrospectively. Method: We examined the demographic characteristics, the histological type, the stage of the lung cancer, the type of the surgical procedure used, other supplemental treatment and survival retrospectively. Results: Lung cancer has occurred 50 per cent more often among females in the last decade. This growth is due to the increase of adenocarcinoma cases. Thanks to the improving diagnostic modalities and the routine follow-up of oncological patients, the number of I/A cases has been doubled recently and the preoperative staging and physical condition check-up have become more accurate. Neoadjuvant treatment has been introduced, the proportion of sublobar resections has risen, the ratio of pneumonectomy and sleeve lobectomy has become equal, so many previously unresectable cases turned to be resectable and the tolerance of adjuvant therapy has also improved. Videothoracoscopic lobectomy has become an everyday practice, leading to a decrease in the operative stress on patients. Conclusion: In spite of this development, the five-year survival has not changed significantly, staying around 50%. Orv Hetil. 2018; 159(10): 391–396.

Abstract:

The differential diagnosis of acute abdominal complaints is challenging in Crohn’s disease. This is particularly true in patients in remission induced by biological therapy. In addition to the acute relapse of Crohn’s disease, other common causes, such as acute appendicitis exhibiting similar and often atypical course, should be taken into consideration irrespective of the age. An ileocecal flare-up is unlikely to occur in patients with perianal Crohn’s disease in remission induced by infliximab even if laboratory and radiological findings point towards this diagnosis. We report the case of a middle-aged woman in remission induced by infliximab who developed acute abdominal symptoms due to perforated appendicitis. Orv Hetil. 2018; 159(10): 405–409.

Abstract:

Coffee consumption had already been described in the 15th century. The spreading of coffee drinking was not only a consequence of its delicious aromatic taste, but also of its pharmacological effects, especially due to its caffeine content. In this review, the mechanisms behind its complex stimulatory effects and the latest studies on the possible new therapeutic indications of caffeine are summarized. Several papers reported the neuroprotective (in Alzheimer’s and Parkinson’s disease) and hepatoprotective profiles of caffeine, and we show the most promising new results about its preventive properties in dermal malignancies. These findings were described both in cell cultures and in vivo. The application of caffeine and coffee in cosmetology and dermatological products is based on their antioxidant property and on the above-mentioned beneficial effects. Caffeine is also presented here as a dermatological model drug due to its hydrophilic profile. It can be used for designing and comparing different novel drug formulations, although beside the transcellular route, the follicular and transappendageal pathways play also important roles in its skin penetration. Taken together, caffeine molecule has many recently discovered beneficial pharmacological effects, but one should be careful with its excessive consumption. It can result in several adverse events if overdosed and in case of regular intake of high doses, after abandonment, withdrawal symptoms may appear. Orv Hetil. 2018; 159(10): 384–390.

Abstract:

Numerous outstanding summarizing publications on the milestones of the rapid development of liver surgery in the twentieth century came to light around the year 2000, therefore in this summary only the newest principles and novelties of liver surgery after the second millennium are presented. Among the new principles, the newest indications, the bloodless surgery and the vascular exclusion of the liver, the “associating liver partition and portal vein occlusion for staged hepatectomy” (ALPPS) – as presently the fastest and most successful method for liver regeneration, and the “downsizing of tumors” treatment for the interest of resection of unresectable tumours are analyzed and evaluated. Open, laparoscopic, and robotic liver surgery are discussed by comparing blood loss, operating time, cost, and long-term results. Laparoscopic liver surgery on the basis of evidences has become “the method of choice” in our days. Robotic liver surgery needs further evidence-based data for determination of its place in the clinical practice. An intention is also composed in terms of place-determination of liver surgery between gastrointestinal, hepatopancreatobiliary, liver transplantation, and oncologic surgery. The mortality rate has decreased to 1% recently; the data regarding morbidity are variable; the modified Clavien–Dindo, the modified Accordion complication system and the comprehensive complication index are intended to move the different evaluations to a common ground. The up-to-date idea of hepatic surgeon, liver center and liver surgery are defined in close cooperation with international theoretical and practical outcome, in the limelight of multidisciplinarity and multimodality. The internationally observed inequalities in liver surgery are also discussed from the point of view of tackling with the inequalities existing in the universal healthcare systems on a local, national and global level by collecting and controlling the results systematically, and developing and implying international guidelines on the basis of evidences.

In this article, we use cusp catastrophe model for analyze the intelligence. Definition of intelligence is restricted by IQ that can be separated to two aspects, those are Concrete-Practice (CP) and Theoretical-Verbal (TV). We will demonstrate that two students of university with the same aspect of intelligence, CP, but have different TV will state in different department of a university. We must get the critical point that differentiate the characteristic of one department with the others. Moving from one department to the other caused by the change of TV will occur as a jump. This jump will determined cusp catastrophe model.Catastrophe theory provides a universal method for the study of all jump transitions, discontinuities, and sudden qualitative changes. Especially in mathematical understanding, catastrophe theory is a part of singularities theory and bifurcation theory.The samples were the psychological testing, IST, results of 428 ITB's students. The first step is Confirmatory Factor Analysis application to reduce nine psychotest variables to get two control variables that construct cusp catastrophe model. The second step is fitting the model of cusp catastrophe to the data with Cuspfit procedure. As measurement of goodness of fit, Cuspfit procedure uses the Akaike Information Criterion (AIC) and Bayes Information Criterion (BIC). The model with the lowest AIC and BIC is selected.

Tingkat pemanfaatan (E) sebesar 0,35 dan upaya penangkapan (F) lebih kecil dari titik acuan (Fcur=0,25; Fmax=1,2; F0,1=0,9) pada ukuran rata-rata pertama tertangkap (Lc) sebesar 38,1 cm, menunjukkan upaya penangkapan mendekati optimum dan masih dapat dikembangkan. Estimasi rasio pemijahan sebesar 51% pada panjang rata-rata 48,17 cm TL lebih besar dari titik referensi minimum ikan kakap sebesar 26%. Pengelolaan yang disarankan berdasarkan penelitian ini adalah upaya pengusahaan kakap merah dapat dikembangkan hingga 30% dari upaya saat ini dengan diikuti oleh pengaturan ukuran ikan tertangkap lebih besar dari ukuran pertama kali memijah yaitu sebesar 45 cm.Red snapper (Lutjanus malabaricus Schneider, 1801) fishing as one of the main fisheries business in Sinjai need information on exploitation level as basis for formulating proper management. The aims of this research were to study growth, yield per recruit and spawning potential ratio (SPR) of red snapper in Sinjai and adjacent waters. This research was conducted in January – November 2016 and fish samples were measured by enumerator. Yield per recruit analysis used Beverton & Holt method and spawning potential ratio analysis used length based SPR. The results showed that the asymptotic length was 77,3 cm and the growth parameter of red snapper was 0,293 year-1. Exploitation rate (E) was 0,35 and fishing effort (F) less than reference point (Fcur=0,25,;Fmax=1,2 ; F0,1=0,9) on size at first captured (Lc) 38,1 cm, indicating fishing effort has closed to optimum and can be developed. Spawning potential ratio was 51%, with 48,17 cmTL of mean size, larger than limit reference point that was 26%. Recommended management measures based on this research were that fishing effort of red snapper can be increased until 30% from current effort followed by size regulation to catch above size at first matured at 45 cm.

Sumberdaya udang barong lumpur (Panulirus polyphagus Herbst, 1793) atau dalam bahasa lokal dikenal sebagai lobster Pakistan telah dimanfaatkan sebagai salah satu komoditas yang bernilai ekonomis di perairan pulau Sebatik, Kalimantan Utara. Data statistik perikanan menunjukkan produksi udang barong di perairan Timur Kalimantan tahun 2005 – 2015 meningkat pesat dengan kelipatan 10 kalinya. Terkait dengan fenomena tersebut, penelitian tentang aspek biologi populasi telah dilakukan pada bulan Maret sampai dengan November 2016. Penelitian ini bertujuan untuk mendapatkan parameter populasi sebagai landasan untuk mengetahui status stok pada tingkat pemanfaatan terkini. Hasil penelitian menunjukkan udang betina tertangkap pada ukuran rata-rata 86,9+ 8,58 mmCL sedangkan udang jantan pada ukuran 81,5 + 9,63 mmCL. Pola pertumbuhan udang jantan dan betina bersifat allometrik negatif (b<3). Estimasi panjang asimtotis (CL) sebesar 124,1 mm dengan laju pertumbuhan (K) 0,598/tahun. Rata-rata ukuran pertama tertangkap (CLc) adalah 84,5 mmCL. Nilai tersebut lebih rendah dari pertama kali matang gonad (CLm) sebesar 90,74 mmCL. Laju kematian total (Z) sebesar 2,26/tahun, laju kematian alamiah (M) 0,87/tahun serta laju kematian akibat penangkapan (F) 1,39/tahun. Estimasi laju eksploitasi cenderung mengarah kepada penangkapan berlebih (E = 0,61), oleh karena itu perlu dilakukan tindakan pengelolaan melalui pendekatan pengendalian upaya penangkapan dan pembatasan ukuran minimum yang boleh ditangkap. Mud spiny lobster (Panulirus polyphagus Herbst, 1793) or locally known as Pakistan lobster has been exploited as an important economic species in the waters of Sebatik Island, North Kalimantan. The best available capture fisheries statisticon 2005-2015 indicates the production of marine lobster were significantly increased by 10. Based on this phenomenon, observations on biological aspects were carried out during period of March to November 2016. The aim of this study were to estimate of stock status under existing fisheries condition. The result showed that the average size of females was 86.9+ 8.58 cmCL and males was 81.5 + 9.63 mmCL. The growth pattern indicates allometric negative (b<3). Population parameter performed by length based analysis indicates that asymptotic length (CL) was 124.1 mmCL with growth rate (K) of 0.598/yr.The average size of first capture (Lc) was estimated at 84.5 mmCL. This value was less than average size of first mature (CLm) of 90.7 cmCL.The predicted annual total mortality rates (Z) was 2.26/yr, the natural mortality (M) was 0.87/yr, and fishing mortalities (F) was 1.39/yr. The exploitation rates (E) of 0.61 tend to be beyond the sustainable exploitation level. To reduce the fishing mortality, the initiative of specific local management plan on restructuring active fleet and establishing minimum legal size should be implemented.

Ikan terubuk (Tenualosa macrura Bleeker, 1852) merupakan komoditas perikanan yang penting di Bengkalis, Provinsi Riau. Populasi terubuk di Bengkalis sangat menurun akibat dieksploitasi meskipun pembatasan penangkapan juga telah diterapkan melalui metode konservasi. Upaya selain konservasi juga melalui budidaya ikan namun upaya ini terkendala oleh ketersedian ikan terubuk hidup baik sebagai induk maupun ikan dewasa. Tulisan ini membahas hasil uji coba pengoperasian alat penangkap ikan jaring dua lapis untuk menangkap ikan terubuk hidup. Uji coba penangkapan dilaksanakan pada tahun 2015 – 2016 di perairan Selat Bengkalis dan sekitarnya. Hasil uji coba penangkapan menunjukkan bahwa jenis ikan yang dominan tertangkap adalah ikan biang-biang (Setipinna breviceps) dan nomei (Harpodon sp). Laju tangkap jaring dua lapis terhadap ikan terubuk berkisar 0,7 - 2,6 ekor/setting. Jumlah ikan terubuk yang tertangkap dalam kondisi hidup mencapai 27,1% dari total tangkapan ikan terubuk. Nilai ukuran panjang pertama kali tertangkap ikan terubuk dengan jaring dua lapis (Lc) yaitu 17,43 cmFL. Terubok (Tenualosa macrura Bleeker, 1852) is an important fish commodity in Bengkalis, Riau Province. The terubok resosurce in Bengkalis is heavily degraded due to the high exploitation even fishing limitation was applied in term of species conservation. Conservation efforts through fishculture are constrained by the availability of live terobuk fish as both parent and adult fish. This paper present the results of fishing trial of double-net fishing gear for catching alive terubok fish. Fishing trial was conducted in 2015-2016 periods in Bengkalis strait waters and its adjascent. The results shown that the dominant fish catches of doublé net were Shorthead hairfin anchovy (Setipinna breviceps) and bombay duck (Harpodon sp). Double gill net catch rate for terubok were between 0,7 -2,6 fish/setting. Number of alive terubok fish was 27,1% of total terubok catches, length of first capture (Lc) value of terubok by using doublé net was 17.4 cm FL.

O presente artigo visou mostrar alguns fatores, que podem levar as empresas a terem sucesso ou fracasso na tentativa do uso da manufatura enxuta pela realização de um estudo de múltiplos casos onde são apresentadas duas situações de sucesso e três condições de fracasso em uma pesquisa realizada com cinco empresas de grande porte, todas pertencentes ao setor metal mecânico, situados na região entre Campinas e Sorocaba ambos no estado de São Paulo. Os dados foram coletados utilizando-se de uma pesquisa exploratória entre os períodos de janeiro de 2013 a fevereiro de 2015. Os resultados obtidos mostram que os casos bem sucedidos de implantação da manufatura enxuta resultam de ambientes de trabalho mais organizados, padronização das áreas produtivas e áreas de apoio, satisfação dos colaboradores, resultados de produtividade e qualidade do produto final ao passo que as implantações mal sucedidas resultam de um planejamento mal executado e falho que não traz benefícios e acaba por diminuir o moral de seus funcionários, trazer mais desconfianças e frustações influenciando diretamente nos resultados e também na produtividade, ou seja, uma implantação da manufatura enxuta necessita de um trabalho árduo e contínuo e estes procedimentos devem estar alinhados com as missões e os objetivos das empresas e principalmente a manutenção do foco no resultado através da utilização de ferramentas para monitorar e acompanhar o processo de forma sistemática e também a realização de investimentos no sentido de eliminar os desperdícios.

Published: March 2018

O conceito de Product Service System (PSS) propõe um modelo de negócio focado em fornecer um resultado específico ao cliente, ao contrário de entregar somente um produto físico. Embora muitos pesquisadores afirmem que a cultura é um elemento essencial ao desenvolvimento do PSS, o relacionamento específico entre esses dois assuntos não é totalmente compreendido. Portanto, o presente estudo pretende ilustrar o tipo de cultura necessária para uma melhor implementação do PSS nas empresas, e fornecer um construto teórico com o intuito de desenvolver um melhor entendimento sobre esse assunto. Baseado em uma revisão da literatura, um quadro explicando o relacionamento entre as dimensões culturais e o PSS foi desenvolvido. Os resultados indicam quem o desenvolvimento do PSS será facilitado em um ambiente de baixa aversão à incerteza, coletivismo, feminilidade, e orientação de longo-prazo.

O crescente processo de internacionalização experimentado pelas empresas, especialmente no caso brasileiro, com fraca proteção ao investidor, provoca discussões acerca de questões pertinentes como o nível de disclosure ou transparência que a empresa mantém com seus stakeholders. O objetivo do trabalho é analisar a previsão de earnings management a partir da internacionalização por meio das Redes Neurais Artificias (RNAs). Ou seja, neste estudo foi utilizada o método de RNAs como uma análise complementar à regressão linear múltipla, suprindo os problemas que possam ter sido ocasionados por distorções, ruídos e dados irrelevantes na base de dados, para analisar o impacto da internacionalização no gerenciamento de resultados. Determinada a existência e o efeito da relação entre earnings management e internacionalização, foram estipulados os neurônios de entrada, sendo as variáveis independentes do modelo de regressão, que são as proxies de internacionalização (DOI, ADR, EXPVENDAS) e o neurônio de saída a variável dependente do modelo, que é a proxy para transparência – earnings management (TR4).Para todas as configurações de Redes Neurais utilizadas o percentual de acerto para os dados de treinamento foi de 97% e de teste 98%, comprovando a eficácia das Redes Neurais Artificiais na previsão de gerenciamento de resultados.
Exploring the ethnic diversity of UK dentistry
Authors: Neville Patricia
Published: March 2018

This article was migrated. The article was marked as recommended. It is widely acknowledged that there are many social benefits to having a multicultural health force, including ensuring that there is less of a barrier around access for underrepresented groups. Despite this, certain healthcare professions, including dentistry, have struggled with the historical legacy of being conceptualised as a "white" profession and whether it is ethnically representative of the public it serves. This article examines the role and place of ethnicity in the dental profession in the UK. It will describe the changing ethnic composition of UK dentistry and highlight some of the challenges faced by the profession from an equality and diversity perspective. The current qualitative work of the author exploring the barriers and facilitators faced by students from an ethnic background pursuing a career in dentistry will also be introduced. It concludes by encouraging more research on this topic.

Published: March 2018

Background: Acute lung injury is a life threatening condition often requiring mechanical ventilation. Lung-protective ventilation with tidal volumes of 6 mL/kg predicted body weight (PBW, based on sex and body height), is part of current recommended ventilation strategy. However, it is a common practice to visually estimate the body height of mechanically ventilated patients and use these estimates for ventilator settings. We aimed to determine if the common practice of estimating visual height to define tidal volume reduces the possibility of receiving lung-protective ventilation. Methods: In this prospective observational study, 28 mechanically ventilated patients had their height visually estimated by 20 nurses and 20 physicians. All medical professionals calculated the PBW and a corresponding tidal volume with 6 ml/kg/PBW on the basis of their visual estimation. The patients’ true heights were measured and the true PBW with a corresponding tidal volume was calculated. Finally, estimates and measurements were compared. Results: 1033 estimations were undertaken by 153 medical professionals. Most estimates were imprecise and resulting data comprised taller body heights, higher PBW and higher tidal volumes (all p≤0.01). Using estimates for tidal-volume definition, patients are exposed to mean tidal volumes of 6.5 ± 0.4 ml/kg/PBW. 526 estimation-based tidal volumes (51.1%) did not provide lung-protective ventilation. Conclusion:The common practice of visually estimating body height and using these estimates for ventilator settings is imprecise and potentially harmful because it reduces the chance of receiving lung-protective ventilation. Avoiding this practice increases the patient safety. Instead, height should be measured as a standard procedure.
