On the Effect of Selective Laser Melting Process Parameters on the Microstructure and Mechanical Properties of Al Alloys
Authors: Maamoun Ahmed , Xue Yi , Elbestawi Mohamed , Veldhuis Stephen
Published: December 2018

Additive manufacturing (AM) offers customization of microstructure and mechanical properties of fabricated components according to the material selected, and process parameters applied. Selective laser melting (SLM) is the commonly used technique for processing high strength aluminum alloys. Selection of SLM process parameters could control the microstructure of parts and their mechanical properties. However, the process parameters limit and defects obtained inside the as-built parts present obstacles to customized part production. This study investigates the influence of SLM process parameters on the quality of as-built Al6061 and AlSi10Mg parts according to the mutual connection between the microstructure characteristics and mechanical properties. The microstructure of both materials was characterized for different parts processed over a wide range of SLM process parameters. The optimized SLM parameters were investigated to eliminate the internal microstructure defects. The behaviour of mechanical properties of parts was presented through regression models generated from the design of experiment (DOE) analysis for the results of hardness, ultimate tensile strength, and yield strength. A comparison between the results obtained and that reported in the literature is presented to illustrate the influence of process parameters, build environment, and powder characteristics on the quality of parts produced. The results obtained from this study could help to customize the part’s quality by satisfying their design requirements in addition to reducing the as-built defects which in turn reduce the amount of the post-processing needed.

Published: December 2018

There is an urgent demand worldwide for the development of highly selective adsorbents and sensors of heavy metal ions and other organic pollutants. Within these environmental and public health frameworks, we are combining the salient features of clays and chelatant polymers to design selective metal ion adsorbents. Towards this end, the ion imprinting approach has been used to develop a novel nanohybrid material for the selective separation of Cu2+ ions in aqueous solution. The Cu2+-imprinted polymer/ montmorillonite nanocomposite (IIP/Mt) and non-imprinted polymer/montmorillonite nanocomposite (NIP/Mt) were prepared by radical photopolymerization process in the visible light. Ion imprinting was indeed important as the recognition of copper ions by IIP/Mt was significantly superior to that of NIP/Mt that is the nanocomposite synthesized in the same way but in the absence of Cu2+ ions. The adsorption process as batch study was investigated under the experimental condition affecting same parameters such as contact time, concentration of ions metals and pH. The adsorption capacity of Cu2+ ions is maximized at pH 5. Removal of Cu2+ ion achieved equilibrium within 15 minutes; the results obtained were found to be fitted by the pseudo-second order kinetics model. The equilibrium process was well described by the Langmuir isothermal model and the maximum adsorption capacity was found to be 23.6 mg/g.
Exploratory and Confirmatory Factor Analysis: Which One to Use First?
Authors: Orcan Fatih
Published: December 2018

There exist differences between the use of Exploratory and Confirmatory Factor analysis at scale adaptation or development studies. The order of factor analysis used would cause the discrepancy in the results. Besides, multiple confirmatory factor analysis would fit well on a single data set. In this study, simulated data sets were fitted to three different models. Based on the results 64% of the data sets fit well on all three models. Also, a different data set was fit both on a confirmatory and an exploratory factor analysis. The result showed that confirmatory factor analyses were not sufficient to detect the best fitting model.

Reasons to be different: a ‘post-1992’ perspective
Authors: Jones Peter
Published: December 2018

At a time when British higher education’s relevance and value for money are increasingly being questioned, I argue that post-1992 universities should resist the temptation to emulate their ‘elite’ counterparts; and suggest some reasons why, and ways in which, they might do things differently. My analysis derives from experience of teaching social sciences (especially sociology) in a post-1992 institution, but may have wider validity.
A holistic framework for developing excellent academic practice
Authors: Pickford Ruth
Published: December 2018

This article outlines an original and practical framework that synoptically integrates the factors underpinning a strategic approach to developing excellent academic practice (DEAP) within an institution.It considers recent developments driving development of ‘excellence’ in academic practice and describes a practical model – based on the requirements of the sector, the needs of institutions and the perspectives and goals of staff – that can be used to meet the desires of the various stakeholders.The framework’s philosophy is that outcomes depend upon three factors: individual colleagues’ attributes at different stages of their career; the opportunities provided at each career stage to develop academic practice; and the agency of the colleague and the institution to engage with one another behaviourally, emotionally and/or cognitively to align these attributes and opportunities.The framework is likely to be of practical use to all staff engaged in developing their own or others’ academic practice, while at the same time offering a theoretical framework for scholarship.

Authors: Solodukha V. A. , Chigir G. G. , Pilipenko V. A. , Filipenya V. A. , Gorushko V. A.
Published: December 2018

The key element determining stability of the semiconductor devices is a gate dielectric. As its thickness reduces in the process of scaling the combined volume of factors determining its electrophysical properties increases. The purpose of this paper is development of the control express method of the error-free running time of the gate dielectric and study the influence of the rapid thermal treatment of the initial silicon wafers and gate dielectric on its reliability.

The paper proposes a model for evaluation of the reliability indicators of the gate dielectrics as per the trial results of the test MDS-structures by means of applying of the ramp-increasing voltage on the gate up to the moment of the structure breakdown at various velocities of the voltage sweep with measurement of the IV-parameters. The proposed model makes it possible to realize the express method of the reliability evaluation of the thin dielectrics right in the production process of the integrated circuits.

On the basis of this method study of the influence of the rapid thermal treatment of the initial silicon wafers of the KEF 4.5, KDB 12 wafers and formed on them by means of the pyrogenic oxidation of the gate dielectric for the error-free running time were performed. It is shown, that rapid thermal treatment of the initial silicon wafers with their subsequent oxidation results in increase of the error-free running time of the gate dielectric on average from 12.9 to 15.9 years (1.23 times greater). Thermal treatment of the initial silicon wafers and gate dielectric makes it possible to expand the error-free running time up to 25.2 years, i.e.1.89 times more, than in the standard process of the pyrogenic oxidation and 1.5 times more, than under application of the rapid thermal treatment of the initial silicon wafers only.
Notas sobre paratopia criadora: o caso de Jane Austen para além de sua fortuna crítica
Authors: Salgado Luciana Salazar , Chieregatti Amanda Aparecida
Published: December 2018

Com base no quadro teórico da Análise do Discurso de tradição francesa, particularmente em trabalhos recentes de Dominique Maingueneau (2006, 2008) sobre o que refere por discurso literário, focalizamos neste artigo um estudo de caso: o funcionamento da autoria de Jane Austen. Mobilizamos, para tanto, noções constitutivas da paratopia criadora, a saber, escritor, inscritor e pessoa. E, então, consideramos, além da produção dos textos autorais, material biográfico e variados estudos que circulam sobre a romancista, que tem fãs no mundo todo, entre os quais muitos se organizam em grupos de estudos e de celebração. Assim, tendo em vista o contexto social da Inglaterra na passagem do século XVIII para o XIX, quando é publicada a obra de Austen, procuramos compreender os elementos constitutivos da consagração da autora, que publicou sob pseudônimo e é aclamada hoje pela construção do que podemos chamar de uma “combativa identidade feminina”.

Published: December 2018

The cooking time of dry bean varies widely by genotype and is also influenced by the growing environment, storage conditions, and cooking method. Thus high‐throughput phenotyping methods to assess cooking time would be useful to breeders interested in developing cultivars with a desired cooking time. The objective of this study was to evaluate the performance of hyperspectral imaging technology for predicting dry bean cooking time. Fourteen dry bean genotypes with a wide range of cooking times were grown in five environments over 2 yr. Hyperspectral images were taken from whole dry seeds, and partial least squares regression models based on the extracted hyperspectral image features were developed to predict water uptake and cooking time of soaked and unsoaked beans. Relatively good predictions of water uptake were obtained, as measured by the correlation coefficient for prediction (Rpred = 0.789) and standard error of prediction (SEP = 4.4%). Good predictions of cooking time for soaked beans (ranging between 19.9–95.5 min) were achieved giving Rpred = 0.886 and SEP = 7.9 min. The prediction models for the cooking time of unsoaked beans (ranging between 80–147 min) were less robust and accurate (Rpred = 0.708, SEP = 10.6 min). This study demonstrated that hyperspectral imaging technology has potential for providing a nondestructive, simple, fast, and economical means for estimating the water uptake and cooking time of dry bean. Moreover, a totally independent set of 110 similar dry bean samples confirmed the suitability of the technique for predicting cooking time of soaked beans after updating the partial least squares model with 20 of the new samples, giving Rpred = 0.872 and SEP = 3.7 min. However, due to the genotypic and phenotypic variability of water absorption and cooking time in dry bean, periodical updates of these prediction models with more samples and new bean accessions, as well as testing other multivariate prediction methods, are needed for further improving model robustness and generalization.

Efforts focused on the genetic improvement of seed morphometric and color traits would greatly benefit from efficient and reliable quantitative phenotypic assessment in a nondestructive manner. Although several seed phenotyping systems exist, none of them combine the cost effectiveness, identity preservation, throughput, and accuracy needed for implementation in plant breeding. We integrated an image analysis component into a single‐seed analyzer (SSA) system that also captures near‐infrared reflectance (NIR) and weight data. Through the development and utilization of an open‐source computational image analysis pipeline, image data acquired by two cameras mounted on the SSA machine were automatically processed to derive estimates of length, width, height, volume, and color for 96 individual dehulled groats (seeds) of five oat (Avena sativa L.) genotypes replicated across days. With the exception of color, the four traits were found to be strongly correlated with and have repeatability comparable to manual measurements. The seed color values had moderately strong correlation with those measured by a colorimeter, but further improvements to the SSA system are needed to increase measurement accuracy. These results demonstrate that the SSA system has the potential to provide a low‐cost solution for the rapid, accurate measurement of morphological traits on individual seeds of oat and potentially other crop species, allowing the screening of seeds from numerous genotypes in breeding programs.

Published: December 2018

FinTech startups and services are one of the most dynamic segments of the modern economy. New financial technologies have already attracted many investors and form millions of budgets. Changing the traditional financial services concept, FinTech companies formed a new niche within the financial services market, the dynamic development of which determines the relevance of the development and implementation of an effective regulatory and oversight system.The purpose of the article is to develop an economic and mathematical model for forecasting the development of the FinTech market on the example of Ukraine. In order to study the development of the FinTech industry, a multiple regression model was presented. The model describes the dependence of the total investment value of FinTech from venture investments in financial technology, venture investments in other technologies and venture investments in online lending. Based on this model, the effect of attracting investments with new FinTech projects on the total volume of investments in the industry was clarified. According to the model, with a change in investments in FinTech by 1%, the total rate of venture investments decreases by 0.03, funds in new projects of other companies grow by 0.05, and venture investments in online lending increase by 0.89. According to the analysis of regulatory legislation in the foreign countries of the FinTech services sphere, it was found that the regulation of most of the risks associated with the development of FinTech services falls within the competence of different supervisory authorities, requiring cross-sectoral cooperation between public institutions.
Design considerations for implementing ceramics in new and existing polymeric UF systems
Authors: Kurth C. J. , Wise Brian L. , Smith Stanton
Published: December 2018

With the latest innovations in production and design, ceramic ultrafiltration (UF) membranes are approaching cost parity with polymeric UF membranes. However, system design and hydraulic/pneumatic cleaning methods (backwash) associated with ceramic UF can prevent the overall system costs from being competitive. An in-depth pilot study of various approaches to hydraulic cleaning and operation cycles was conducted to determine whether appropriate conditions could be found that allow for the design of more financially-attractive ceramic UF systems. The result is an overall system cost that is competitive with that of polymeric UF. Further, a match of operating conditions makes it feasible to retrofit polymeric UF modules with ceramic UF modules with few system modifications. This paper will present the pilot test results using different hydraulic cleaning designs and outline the economic impact on the system.

Published: December 2018

Constant energy supply for decentralized wastewater treatment plants (DWWTPs) is crucial in order to ensure its functionality and prevent contamination of rivers and human illnesses due to pollution. However, power blackouts are a common problem in rural areas, which can affect the reliability of wastewater treatment plants. This paper presents a simulation study of sizing of solar photovoltaics and Sea-Salt batteries for powering a DWWTP working in 100% off-grid mode. The analysis is performed for two different DWWTPs: a prototype membrane bioreactor (MBR) and a Bever III compact wastewater aerobic system. The study is performed using the simulation package DEMKit developed at the University of Twente in the Netherlands. Results show that a solar photovoltaic system of 15 kWp coupled with a 20 kWh Sea-Salt battery may provide 100% of the electricity necessary during summer and up to 75% during winter in the Netherlands for the Bever III. In the case of the MBR, a photovoltaic system of 30 kWp in combination with a Sea-Salt battery of 50 kWh meets 100% of the electricity needs during summer and up to 65% during the winter in the Netherlands. Furthermore, in order to power the DWWTPs during the months of low sunlight, the dimensions of the solar photovoltaic system and the Sea-Salt battery needs to be increased by a factor of three.
Biogas technology diffusion and shortfalls in the central and greater Accra regions of Ghana
Authors: Osei-Marfo M. , Awuah E. , de Vries N. K.
Published: December 2018

The current status of biogas technology in Ghana, a developing country, was explored focusing on factors affecting dissemination of the technology and the associated challenges. Data collection was by personal interview and physical observations, and was conducted between July and October 2017. Non-probabilistic sampling procedures were used to select 61 respondents from 162 users, while 54 digesters were selected from 120 digester sites. The findings revealed that: initial installation and maintenance costs appear high; the needs of most biogas users had not been fully met, thus, they were only partially satisfied with the outcome of the technology; and 21% of the biogas service providers were engineers and 79% from other disciplines (plumbers, masons, carpenters, and graduates from arts, social sciences, business, etc.). These factors affect technology diffusion. In addition, bottlenecks for more intense use of biogas technology that need to be addressed include lack of government subsidies or financial support, poor or unstandardized digester design, lack of gas production, lack of follow-up, lack of maintenance, lack of monitoring, and market value for bio-fertiliser (digestate). It is recommended that financial institutions support individuals and institutions with soft loans to acquire biogas digesters/plants, and that a regulatory body be formed for the activities of biogas service providers in developing countries.
The Need to Consider Context in the Evaluation of Anti-infectious and Immunomodulatory Effects of Vitamin A and its Derivatives
Authors: Xavier-Elsas Pedro , Vieira Bruno M. , Masid-de-Brito Daniela , Barradas Monica G. , Gaspar-Elsas Maria I.C.
Published: December 2018

Vitamin A and its derivatives (retinoids) act as potent regulators in many aspects of mammalian reproduction, development, repair, and maintenance of differentiated tissue functioning. Unlike other vitamins, Vitamin A and retinoids, which have hormonal actions, present significant toxicity, which plays roles in clinically relevant situations, such as hypervitaminosis A and retinoic acid ("differentiation") syndrome. Although clinical presentation is conspicuous in states of insufficient or excessive Vitamin A and retinoid concentration, equally relevant effects on host resistance to specific infectious agents, and in the general maintenance of immune homeostasis, may go unnoticed, because their expression requires either pathogen exposure or the presence of inflammatory co-morbidities. There is a vast literature on the roles played by retinoids in the maintenance of a tolerogenic, noninflammatory environment in the gut mucosa, which is considered by many investigators representative of a general role played by retinoids as anti-inflammatory hormones elsewhere. However, in the gut mucosa itself, as well as in the bone marrow and inflammatory sites, context determines whether one observes an anti-inflammatory or proinflammatory action of retinoids. Both interactions between specialized cell populations, and interactions between retinoids and other classes of mediators/regulators, such as cytokines and glucocorticoid hormones, must be considered as important factors contributing to this overall context. We review evidence from recent studies on mucosal immunity, granulocyte biology and respiratory allergy models, highlighting the relevance of these variables as well as their possible contributions to the observed outcomes.
pLoc_bal-mVirus: Predict Subcellular Localization of Multi-Label Virus Proteins by Chou's General PseAAC and IHTS Treatment to Balance Training Dataset
Authors: Xiao Xuan , Cheng Xiang , Chen Genqiang , Mao Qi , Chou Kuo-Chen
Published: December 2018

Background/Objective:

Knowledge of protein subcellular localization is vitally important for both basic research and drug development. Facing the avalanche of protein sequences emerging in the post-genomic age, it is urgent to develop computational tools for timely and effectively identifying their subcellular localization based on the sequence information alone. Recently, a predictor called “pLoc-mVirus” was developed for identifying the subcellular localization of virus proteins. Its performance is overwhelmingly better than that of the other predictors for the same purpose, particularly in dealing with multi-label systems in which some proteins, known as “multiplex proteins”, may simultaneously occur in, or move between two or more subcellular location sites. Despite the fact that it is indeed a very powerful predictor, more efforts are definitely needed to further improve it. This is because pLoc-mVirus was trained by an extremely skewed dataset in which some subset was over 10 times the size of the other subsets. Accordingly, it cannot avoid the biased consequence caused by such an uneven training dataset.

Methods:

Using the Chou's general PseAAC (Pseudo Amino Acid Composition) approach and the IHTS (Inserting Hypothetical Training Samples) treatment to balance out the training dataset, we have developed a new predictor called “pLoc_bal-mVirus” for predicting the subcellular localization of multi-label virus proteins.

Results:

Cross-validation tests on exactly the same experiment-confirmed dataset have indicated that the proposed new predictor is remarkably superior to pLoc-mVirus, the existing state-of-theart predictor for the same purpose.

Conclusion:

Its user-friendly web-server is available at http://www.jci-bioinfo.cn/pLoc_balmVirus/, by which the majority of experimental scientists can easily get their desired results without the need to go through the detailed complicated mathematics. Accordingly, pLoc_bal-mVirus will become a very useful tool for designing multi-target drugs and in-depth understanding of the biological process in a cell.

Patrimonio, derechos humanos y memoria en Chile. La calificación de los sitios de memoria como patrimonio cultural.
Authors: Alegría Luis , Uribe Natalia
Published: December 2018

La emergencia de una nueva categoría de patrimonio vinculada a la experiencia de las sistemáticas y masivas violaciones de derechos humanos constituye una de las consecuencias insospechadas de la implementación de las estrategias del terrorismo de Estado en Chile. Estas marcas físicas de la última dictadura militar (1973-1990) han quedado expresadas en los calificativos de atrocidad u horror con los cuales se procesan y narran socialmente. Argumentamos que para que aquello fuera posible fue necesario que se dieran tres procesos claves. Primero, la constatación de la experiencia extrema que representó la política del exterminio nazi y su valor universal. Segundo, como un efecto directo de la anterior, la conformación de una cultura de los derechos humanos de carácter planetario y tercero, la ampliación de la concepción tradicional de patrimonio cultural. Solo con la conjunción de estos tres fenómenos es posible identificar hoy a los sitios de memoria como un conjunto de bienes patrimoniales.
Análisis crítico del plan de sauvegarde et de mise en valeur del barrio parisino del Marais a través de su evolución
Authors: Del Andrés , Shimabukuro Shimabukuro Angie
Published: December 2018

El presente artículo ha sido redactado a partir de un trabajo de investigación desarrollado en unos estudios de maestría. Francia posee zonas urbanas protegidas denominadas secteur sauvegardé. La posibilidad de crear y delimitar dichas zonas fue instituida a partir de la promulgación de la Ley Malraux, en 1962. Dichas zonas son sometidas a reglas particulares en función a un Plan de Salvaguardia y de Puesta en Valor (PSMV). La investigación realizada muestra la evolución de los proyectos del PSMV del Marais a partir de 1969 hasta el 2013. El análisis pone en evidencia el resultado de un proceso lento de definición y de adaptaciones sucesivas a los reglamentos implementados. Hay un constante desfase entre los objetivos teórico-práctico definidos desde el punto de vista de la reglamentación y de la aplicación.

Con más de 250 bienes inscritos en la Lista del Patrimonio Mundial, las ciudades representan una de las categorías más abundantes y diversas de la actual herencia cultural de la especie humana. Estas características se suman a la dinámica de la conservación/recuperación/puesta en valor/gestión del patrimonio urbano, donde las teorías, conceptos y enfoques están en cambio y evolución permanente. En ese contexto, con la pretensión de mantenerse a la vanguardia de opiniones y tendencias, y contribuir al debate en curso relacionado al desarrollo de normatividad y la sistematización de buenas prácticas, se creó el Programa de Ciudades Patrimonio de la Humanidad para brindar apoyo y asistencia a los Estados miembros de la Organización de las Naciones Unidas en sus esfuerzos para proteger y poner en valor social su patrimonio urbano. En la medida que las ciudades tienen una agenda siempre dinámica y constante, el Programa Mundial de Ciudades Patrimonio de la Humanidad asumió como objetivo principal contribuir a la reflexión/propuesta de adaptación a las  necesidades de modernización y la inversión en las áreas centrales de las ciudades sin comprometer el carácter histórico e identidad específica con que cuentan.

I also wanted to show Her who always leads to a personal encounter with her Son, or Holy Mary, noted that it is also thanks to the Marian devotions - so widespread in Poland, the faithful "by Mary" come to Jesus that she - Mother leads to the encounter with the Greatest Love latent in the Blessed Sacrament.

BACKGROUND

Electronic health (eHealth) services may help people obtain information and manage their health, and they are gaining attention as technology improves, and as traditional health services are placed under increasing strain. We present findings from the first representative, large-scale, population-based study of eHealth use in Norway.

OBJECTIVE

The objectives of this study were to examine the use of eHealth in a population above 40 years of age, the predictors of eHealth use, and the predictors of taking action following the use of these eHealth services.

METHODS

Data were collected through a questionnaire given to participants in the seventh survey of the Tromsø Study (Tromsø 7). The study involved a representative sample of the Norwegian population aged above 40 years old. A subset of the more extensive questionnaire was explicitly related to eHealth use. Data were analyzed using logistic regression analyses.

RESULTS

Approximately half (52.7%; 9752/18,497) of the respondents had used some form of eHealth services during the last year. About 58% (5624/9698) of the participants who had responded to a question about taking some type of action based on information gained from using eHealth services had done so. The variables of being a woman (OR 1.58; 95% CI 1.47-1.68), of younger age (40-49 year age group: OR 4.28, 95% CI 3.63-5.04), with a higher education (tertiary/long: OR 3.77, 95% CI 3.40-4.19), and a higher income (>1 million kr [US $100,000]: OR 2.19, 95% CI 1.77-2.70) all positively predicted the use of eHealth services. Not living with a spouse (OR 1.14, 95% CI 1.04-1.25), having seen a general practitioner (GP) in the last year (OR 1.66, 95% CI 1.53-1.80), and having had some disease (such as heart disease, cancer, asthma, etc; OR 1.29, 95% CI 1.18-1.41) also positively predicted eHealth use. Self-rated health status did not significantly influence eHealth use. Taking some action following eHealth use was predicted with the variables of being a woman (OR 1.16, 95% CI 1.07-1.27), being younger (40-49 year age group: OR 1.72, 95% CI 1.34-2.22), having a higher education (tertiary/long: OR 1.65, 95% CI 1.42-1.92), having seen a GP in the last year (OR 1.58, 95% CI 1.41-1.77), and having ever had a disease (such as heart disease, cancer or asthma; OR 1.26, 95% CI 1.14-1.39).

CONCLUSIONS

eHealth appears to be an essential supplement to traditional health services for those aged above 40 years old, and especially so for the more resourceful. Being a woman, being younger, having higher education, having had a disease, and having seen a GP in the last year all positively predicted using the internet to get health information and taking some action based on this information.
Theories Predicting End-User Acceptance of Telemedicine Use: Systematic Review (Preprint)
Authors: Harst Lorenz , Lantzsch Hendrikje , Scheibe Madlen
Published: December 2018

BACKGROUND

Only a few telemedicine applications have made their way into regular care. One reason is the lack of acceptance of telemedicine by potential end users.

OBJECTIVE

The aim of this systematic review was to identify theoretical predictors that influence the acceptance of telemedicine.

METHODS

An electronic search was conducted in PubMed and PsycINFO in June 2018 and supplemented by a hand search. Articles were identified using predefined inclusion and exclusion criteria. In total, two reviewers independently assessed the title, abstract, and full-text screening and then individually performed a quality assessment of all included studies.

RESULTS

Out of 5917 potentially relevant titles (duplicates excluded), 24 studies were included. The Axis Tool for quality assessment of cross-sectional studies revealed a high risk of bias for all studies except for one study. The most commonly used models were the Technology Acceptance Model (n=11) and the Unified Theory of Acceptance and Use of Technology (n=9). The main significant predictors of acceptance were perceived usefulness (n=11), social influences (n=6), and attitude (n=6). The results show a superiority of technology acceptance versus original behavioral models.

CONCLUSIONS

The main finding of this review is the applicability of technology acceptance models and theories on telemedicine adoption. Characteristics of the technology, such as its usefulness, as well as attributes of the individual, such as his or her need for social support, inform end-user acceptance. Therefore, in the future, requirements of the target group and the group’s social environment should already be taken into account when planning telemedicine applications. The results support the importance of theory-guided user-centered design approaches to telemedicine development.
Computerized Clinical Decision Support System for Emergency Department–Initiated Buprenorphine for Opioid Use Disorder: User-Centered Design (Preprint)

Published: December 2018

BACKGROUND

Emergency departments (EDs) frequently care for individuals with opioid use disorder (OUD). Buprenorphine (BUP) is an effective treatment option for patients with OUD that can safely be initiated in the ED. At present, BUP is rarely initiated as a part of routine ED care. Clinical decision support (CDS) could accelerate adoption of ED-initiated BUP into routine emergency care.

OBJECTIVE

This study aimed to design and formatively evaluate a user-centered decision support tool for ED initiation of BUP for patients with OUD.

METHODS

User-centered design with iterative prototype development was used. Initial observations and interviews identified workflows and information needs. The design team and key stakeholders reviewed prototype designs to ensure accuracy. A total of 5 prototypes were evaluated and iteratively refined based on input from 26 attending and resident physicians.

RESULTS

Early feedback identified concerns with the initial CDS design: an alert with several screens. The timing of the alert led to quick dismissal without using the tool. User feedback on subsequent iterations informed the development of a flexible tool to support clinicians with varied levels of experience with the intervention by providing both one-click options for direct activation of care pathways and user-activated support for critical decision points. The final design resolved challenging navigation issues through targeted placement, color, and design of the decision support modules and care pathways. In final testing, users expressed that the tool could be easily learned without training and was reasonable for use during routine emergency care.

CONCLUSIONS

A user-centered design process helped designers to better understand users’ needs for a Web-based clinical decision tool to support ED initiation of BUP for OUD. The process identified varying needs across user experience and familiarity with the protocol, leading to a flexible design supporting both direct care pathways and user-initiated decision support.

Published: December 2018

BACKGROUND

Many university students are lacking adequate physical exercise and are failing to develop physical activity (PA) behaviors in China. PA app use could improve this situation.

OBJECTIVE

The aim of this study was to use the unified theory of acceptance and use of technology (UTAUT) to investigate the intention to use PA apps among university students in Guangzhou, China, and how body mass index (BMI) moderates the effects of UTAUT in explaining PA app use intention.

METHODS

A cross-sectional study was conducted among 1704 university students from different universities in Guangzhou, China. The UTAUT model was used to measure the determinants of intention to use PA apps.

RESULTS

Of the participants, 41.8% (611/1461) intended to use PA apps. All three UTAUT-related scales (performance expectancy, effort expectancy, and social influence) were positively associated with the intention to use PA apps after adjusting for background variables (adjusted odds ratio 1.10-1.31, P<.001). The performance expectancy scale had stronger associations with the intention to use PA apps among those whose BMI were beyond normal range compared with those whose BMI were within normal range (P<.001).

CONCLUSIONS

UTAUT is useful for understanding university students’ intention to use PA apps. Potential moderating effects should be kept in mind when designing UTAUT-based interventions to improve PA via app use.
