Development of Computer Vision Based Face Tracking Measurement for Sitting Ergonomics
Year: 2016

Sitting causes major health problems. Both bad sitting posture and prolonged sitting time increases the likelihood of back pain. The object of our research was to study if it is possible to measure sitting ergonomics using a webcam video. The webcam placed in front of a subject was tracking the movements of subject's face, which were used to derive the pose of subject's head. Different algorithms to detect bad posture based on head pose and movement were developed according to the physiological recommendations. The accuracy of these algorithms were investigated in a real environment testing. Although the results are promising, more research is needed to develop better algorithms for a more accurate and versatile detection of sitting ergonomics.
The Size of the Lgbt Population and the Magnitude of Anti Gay Sentiment are Substantially Underestimated
Venue: Manag. Sci.
Year: 2017

We demonstrate that widely used measures of antigay sentiment and the size of the lesbian, gay, bisexual, and transgender (LGBT) population are misestimated, likely substantially. In a series of online experiments using a large and diverse but nonrepresentative sample, we compare estimates from the standard methodology of asking sensitive questions to measures from a "veiled" methodology that precludes inference about an individual but provides population estimates. The veiled method increased self reports of antigay sentiment, particularly in the workplace: respondents were 67% more likely to disapprove of an openly gay manager when asked with a veil, and 71% more likely to say it should be legal to discriminate in hiring on the basis of sexual orientation. The veiled methodology also produces larger estimates of the fraction of the population that identifies as LGBT or has had a sexual experience with a member of the same sex. Self reports of nonheterosexual identity rose by 65% and same sex sexual exp.
Community differentiation and kinship among Europe's first farmers
Venue: Proceedings of the National Academy of Sciences
Year: 2012

Community differentiation is a fundamental topic of the social sciences, and its prehistoric origins in Europe are typically assumed to lie among the complex, densely populated societies that developed millennia after their Neolithic predecessors. Here we present the earliest, statistically significant evidence for such differentiation among the first farmers of Neolithic Europe. By using strontium isotopic data from more than 300 early Neolithic human skeletons, we find significantly less variance in geographic signatures among males than we find among females, and less variance among burials with ground stone adzes than burials without such adzes. From this, in context with other available evidence, we infer differential land use in early Neolithic central Europe within a patrilocal kinship system.

Marginal Structural Models with Counterfactual Effect Modifiers
Venue: The international journal of biostatistics
Year: 2018

In health and social sciences, research questions often involve systematic assessment of the modification of treatment causal effect by patient characteristics. In longitudinal settings, time varying or post intervention effect modifiers are also of interest. In this work, we investigate the robust and efficient estimation of the Counterfactual History Adjusted Marginal Structural Model (van der Laan MJ, Petersen M. Statistical learning of origin specific statically optimal individualized treatment rules.  2007;3) which models the conditional intervention specific mean outcome given a counterfactual modifier history in an ideal experiment. We establish the semiparametric efficiency theory for these models, and present a substitution based, semiparametric efficient and doubly robust estimator using the targeted maximum likelihood estimation methodology (TMLE, e.g. van der Laan MJ, Rubin DB. Targeted maximum likelihood learning.  2006;2, van der Laan MJ, Rose S. Targeted learning: causal inference for observational and experimental data, 1st ed. Springer Series in Statistics. Springer, 2011) To facilitate implementation in applications where the effect modifier is high dimensional, our third contribution is a projected influence function (and the corresponding projected TMLE estimator) which retains most of the robustness of its efficient peer and can be easily implemented in applications where the use of the efficient influence function becomes taxing. We compare the projected TMLE estimator with an Inverse Probability of Treatment Weighted estimator (e.g. Robins JM. Marginal structural models.  Section on Bayesian Statistical Science, 1 10. 1997a, Hernan MA, Brumback B, Robins JM. Marginal structural models to estimate the causal effect of zidovudine on the survival of HIV positive men. Epidemiology. 2000;11:561 570) and a non targeted G computation estimator (Robins JM. A new approach to causal inference in mortality studies with sustained exposure periods application to control of the healthy worker survivor effect.  The comparative performance of these estimators is assessed in a simulation study. The use of the projected TMLE estimator is illustrated in a secondary data analysis for the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial where effect modifiers are subject to missing at random.
A Comparative Study on Emotional Intelligence of Parents with Autism Spectrum Disorders Children and Children with Normal Development
Year: 2018

Studies suggested that parenting a child with a disability have more difficulties than parenting of healthy children because developing a child with disabilities is associated with negative emotions and be frustrating and stressful in both physical and emotional aspects. It is noteworthy that the psychological health of parents has a direct impact on the children's social, emotional, cognitive and behavioral development and with attachment quality, taking part in the education and treatment of their child, taking care of other members of the family and their psychological health. In general, emotional intelligence has a strong correlation with the ability to deal with problems, adjustment, positive judgment, decision making, extraversion, flexibility, happiness and ability to coordinate the feelings and psychological development. Therefore, due to the importance of emotional intelligence in parents of autistic children, the present study was conducted to compare the emotional intelligence of children with autism spectrum disorder parents' and parents of children with typical development.  This study was causal comparative research, and its statistical population was parents of children with autism spectrum disorder and parents of children with typical development in Uremia city (Northwest of Iran) A total of 50 couples with children with autism spectrum disorder were selected by availability sampling method from related keeping and educational center and a total of 50 couples with normal development children which were selected by multistage cluster sampling method from ordinary schools. Inclusion criteria for research were to have at least one child with an autism spectrum disorder in a family with having autism spectrum disorder child and had above secondary education of parents in both groups. Exclusion criteria were having psychotic disorders and mental retardation of parents in both groups. To data analysis, a T statistical model for two independent groups was used for two separate groups. The bar on emotional quotient inventory was used to collect data. This scale formed to assess capabilities, qualifications, and no cognitive skills that considered being on a person's ability to succeed in coping with environmental demands and pressures convenience.  The results indicated that there was a significant difference between general emotional intelligence of children autism spectrum disorder parents with normal development children (p=0.02) In addition, there was a significant difference between some features of emotional intelligence including problem solving (p=0.04) happiness (p<0.001) interpersonal relationships (p=0.03) optimism (p<0.001) self esteem (p=0.05) and flexibility (p=0.01)  According to the findings of lower general emotional intelligence and some it factors in parents of children with an autism spectrum disorder, educational program in this field should be considered in early intervention for them.
Bilingualism: The good, the bad, and the indifferent*
Venue: Bilingualism: Language and Cognition
Year: 2009

The present paper summarizes research showing that bilingualism affects linguistic and cognitive performance across the lifespan. The effect on linguistic performance is generally seen as a deficit in which bilingual children control a smaller vocabulary than their monolingual peers and bilingual adults perform more poorly on rapid lexical retrieval tasks. The effect on cognitive performance is to enhance executive functioning and to protect against the decline of executive control in aging. These effects interact to produce a complex pattern regarding the effect of bilingualism on memory performance. Memory tasks based primarily on verbal recall are performed more poorly by bilinguals but memory tasks based primarily on executive control are performed better by bilinguals. Speculations regarding the mechanism responsible for these effects are described.
Photonic Crystals Assembled by SiO2@Ni/TiO2 for Photocatalytic Reduction of CO2
Venue: Catalysis Letters
Year: 2020

Photonic crystal (PC) can manipulate light propagation due to the presence of photonic band gap (PBG) PBG can redistribute density of optical state. When the PBG overlaps with the emission of an emitter embedded in PC, the excited electrons will be prohibited from transferring to the ground state. Introducing PC with suitable PBG into photocatalyst will partially reduce the electron hole combination and improve photocatalytic efficiency. Meanwhile, appropriate specific surface area of 3 D quasi ordered structure can increase the contact area of catalysts and CO2 to provide more catalytic sites, which plays an important role in the improvement of photocatalytic activity. Herein, SiO2@Ni/TiO2 PCs with designed PBG were fabricated and applied as catalysts for photocatalytic CO2 reduction using [Ru(bpy)3]Cl2*6H2O as photosensitizer. The designed SiO2@Ni/TiO2 PCs has a suitable specific surface area and certain surface roughness, which can effectively adsorb CO2 for photocatalytic reduction. Meanwhile, the PBG of SiO2@Ni/TiO2 PCs matches well with the electron hole combination energy of the photosensitizer, the electron hole combination process from the excited state falling back to the ground state can be prevented partially. Suppressing the falling of excited electrons will make electrons transfer to the catalyst, thereby improving the photocatalytic performance.
Relation Between Mathematical Performance, Math Anxiety, and Affective Priming in Children With and Without Developmental Dyscalculia
Venue: Front. Psychol.
Year: 2018

Many children show negative emotions related to mathematics and some even develop mathematics anxiety. The present study focused on the relation between negative emotions and arithmetical performance in children with and without developmental dyscalculia (DD) using an affective priming task. Previous findings suggested that arithmetic performance is influenced if an affective prime precedes the presentation of an arithmetic problem. In children with DD specifically, responses to arithmetic operations are supposed to be facilitated by both negative and mathematics related primes =negative math priming effect).We investigated mathematical performance, math anxiety, and the domain general abilities of 172 primary school children (76 with DD and 96 controls) All participants also underwent an affective priming task which consisted of the decision whether a simple arithmetic operation (addition or subtraction) that was preceded by a prime (positive/negative/neutral or mathematics related) was true or false. Our findings did not reveal a negative math priming effect in children with DD. Furthermore, when considering accuracy levels, gender, or math anxiety, the negative math priming effect could not be replicated. However, children with DD showed more math anxiety when explicitly assessed by a specific math anxiety interview and showed lower mathematical performance compared to controls. Moreover, math anxiety was equally present in boys and girls, even in the earliest stages of schooling, and interfered negatively with performance. In conclusion, mathematics is often associated with negative emotions that can be manifested in specific math anxiety, particularly in children with DD. Importantly, present findings suggest that in the assessed age group, it is more reliable to judge math anxiety and investigate its effects on mathematical performance explicitly by adequate questionnaires than by an affective math priming task.
Dual segment variable gain sliding mode control based on neural network for permanent magnet synchronous motor servo drives
Venue: 2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)
Year: 2018

Aimed at the problem of high precision position control system in modern industrial control, a novel dual segment variable gain sliding mode controller based on permanent magnet synchronous motor (PMSM) is designed. Different from the traditional control system of three closed loop vector, the dual segment variable gain sliding mode controller adopts the integrated design of velocity segment and position segment to carry out time sharing control according to the different operating states of the system. The variable gain global sliding mode controller is adopted in the velocity segment, and the integral sliding mode controller with variable gain is used in the position segment. The control law of the sliding surface of the velocity and position segments is composed of the equivalent control law and switching control law. In order to further improve the robustness of the system, the RBF neural network is introduced to get the switching control law. The simulation results show that the controller has good speed response performance and anti interference ability.
Privacidad, seguridad y legalidad en soluciones educativas basadas en Blockchain: Una Revision Sistematica de la Literatura
Year: 2020

La Analitica del Aprendizaje (proveniente del termino en ingles Learning Analytics) procesa los datos de los estudiantes, incluso los estudiantes menores de edad. El ciclo analitico consiste en recoger datos, almacenarlos durante largos periodos y utilizarlos para realizar analisis y visualizaciones. A mayor cantidad de datos, mejores resultados en el analisis. Este analisis puede ser descriptivo, predictivo e, incluso, prescriptivo, lo que implica la gestion, el tratamiento y la utilizacion de datos personales. El contexto educativo es, por lo tanto, muy sensible, a diferencia de los contextos individuales en los que el analisis se utiliza a voluntad. No esta claro como estan utilizando los datos de los estudiantes las empresas de tecnologia que dan servicio en educacion y a quienes realmente se les beneficia, como esto afectara a los estudiantes en un futuro a corto y largo plazo, o que nivel de privacidad o seguridad se aplica para proteger los datos de los estudiantes. Por consiguiente, y en relacion con lo expuesto, el analisis de datos educativos implica un contexto sensible y de fragilidad en la gestion y analisis de datos personales de los estudiantes, incluidos menores, en el que hay que maximizar las precauciones. En esta revision sistematica de la literatura se explora la importancia de la proteccion y seguridad de los datos personales en el campo de la educacion mediante las promesas emergentes de los interesados en usar la tecnologia blockchain Los resultados denotan que es importante entender las implicaciones y riesgos derivados de usar tecnologias emergentes en educacion, su relacion con la sociedad y la legalidad vigente.
Implementing the 4D cycle of appreciative inquiry in health care: a methodological review.
Venue: Journal of advanced nursing
Year: 2013

To examine and critique how the phases of the 4D cycle (Discovery, Dream, Design, and Destiny) of appreciative inquiry are implemented in a healthcare context.  Appreciative inquiry is a theoretical research perspective, an emerging research methodology and a world view that builds on action research, organizational learning, and organizational change. Increasing numbers of articles published provide insights and learning into its theoretical and philosophical underpinnings. Many articles describe appreciative inquiry and the outcomes of their studies; however, there is a gap in the literature examining the approaches commonly used to implement the 4D cycle in a healthcare context.  A methodological review following systematic principles.  A methodological review was conducted including articles from the inception of appreciative inquiry in 1986 to the time of writing this review in November, 2011. Key database searches included CINAHL, Emerald, MEDLINE, PubMed, PsycINFO, and Scopus.  A methodological review following systematic principles was undertaken. Studies were included if they described in detail the methods used to implement the 4D cycle of appreciative inquiry in a healthcare context.  Nine qualitative studies met the inclusion criteria. Results highlighted that appreciative inquiry application is unique and varied between studies. The 4D phases were not rigid steps and were adapted to the setting and participants.  Overall, participant enthusiasm and commitment were highlighted suggesting appreciative inquiry was mostly positively perceived by participants. Appreciative inquiry provides a positive way forward shifting from problems to solutions offering a new way of practicing in health care and health research.
Gelation, flame retardancy, and physical properties of phosphorylated microcrystalline cellulose aerogels.
Venue: Carbohydrate polymers
Year: 2020

Flame retardant bio based cellulose aerogels, with abundant renewable sources, are considered as promising sustainable heat insulation alternatives to conventional petroleum based foams. An environmentally friendly method was employed to fabricate phosphorylated microcrystalline cellulose (PMCC) aerogel through the gelation of PMCC/H2O dispersion and freeze drying of PMCC hydrogel. The dispersion stability of PMCC and its readiness to undergo gelation in the aqueous phase were enhanced by increasing the phosphorous content via phosphorylation, thereby effectively weakening the strong intra and intermolecular hydrogen bond interactions of the cellulose chains. The morphology of the PMCC aerogel changed from a short rod shaped and sheet like aggregation of a three dimensional skeleton structure to a mostly sheet like aggregation of a three dimensional structure with increased phosphate esterification. Remarkably, PMCC aerogels exhibited improved flame retardancy and superior suppression of toxic gas, compared to MCC. This is attributable to the synergic effect of phosphate dehydration, catalytic carbonization, and protection of the aerogel network structure.
Content analysis of websites selling alcohol online in Australia.
Venue: Drug and alcohol review
Year: 2020

Online alcohol sales have experienced rapid growth in Australia in recent years, averaging 14% annual growth over the last 5 years. This study aims to provide information about the advertised sales and delivery practices of online alcohol retailers in Australia and the potential implications for alcohol related harm.  A cross sectional website content analysis of the 65 most visited Australian alcohol delivery websites. Data extracted for content analysis from each of the included websites fell under six broad categories: product range; average prices; promotions and discounting; payment and delivery; age verification methods; and policy statements.  Online alcohol retailers offer a variety of alcohol products cheaply, with around 20% selling a 750 mL bottle of wine for under AUD$5. Most (81.5% offered discounts for purchasing greater quantities and (89.2% offered visitors an opportunity to sign up to receive discounts and promotions directly via email. Concerningly, 13.8% of websites allowed customers to purchase alcohol using a 'buy now, pay later' scheme such as AfterPay or Zip Pay. Delivery in under two hours was available from 12% of retailers. Most retailers (75.4% advertised a willingness to leave alcohol unattended at an address.  Online alcohol retailers offer a variety of alcohol products cheaply, accompanied by heavy promotions and discounting. Most retailers advertise a willingness to leave alcohol unattended at an address without having verified the purchasers age, which raises concerns about access to minors. Improved regulation of this growing industry in Australia is required. [Colbert S, Thornton L, Richmond R. Content analysis of websites selling alcohol online in Australia.
