Assistive technologies and habit development:a Semiotic Model of Technological Mediation

In the field of philosophy of technology,the concept of mediation is central to understanding how technology shapes human experience and behavior.Our aim in this paper is to contribute to the understanding of technological mediation,in particular how and why it is possible.Technological mediation occurs within a mediation space between the technological realm and the user realm.In the technological realm,technology regularizes events and actions,while in the user realm,the user interprets the significative potential of the technology.This interpretation process is identical with use and involves the formation of user habits,which are constrained by technological,cognitive,and sociocultural factors.To provide a theoretical framework for our analysis,we propose the Semiotic Model of Technological Mediation(SMTM),which draws on Charles Peirceʼs semiotics.To illustrate our argument,we focus on assistive technology and provide a recurring example of the Medimi®Smart,a digital,comprehensive system for medication handling.

Several Legal Issues Relating to Service Technological Results

How "the rights and interests in the intellectual property rights of the scientists and technicians should be protected and the entity achieving the service-related technological results should remunerate, under law, those achieving the service-related technological results and those making outstanding contribution to the transfer of the technological results" are important issues encountered in China in its efforts to improve its innovation capacity and build up a new nation. The current legal system in...

Study on the Application of iTRAQ Technology in Retinal Apoptosis Protein in Diabetic Retinopathy Mice

Objective:Using isobaric tags for relative and absolute quantitation(i TRAQ)technology to study differential protein expression in the retinal tissue of DR mouse models,providing proteomic evidence at the protein level for the pathogenesis of DR.Methods:Firstly,establish diabetic mice and DR mice models,use i TRAQ technology to detect the retinal tissue samples of normal control group and DR model group mice,label the total retinal proteins of mice with i TRAQ reagent,and analyze them using mass spectrometry technology.Evaluate the differential proteins of the two groups using BioWorks TM 3.0 software,and conduct interaction feature analysis on the different proteins using the STRING website.Results:The i TRAQ technology detected a total of 406 different proteins between the diabetes and normal control groups,with 19 of them closely related to retinal cell apoptosis.Among them,significantly different proteins include acyl-CoA dehydrogenase short chain specific(ACADS),ataxin-10(ATXN10),BCL-2-associated X protein(BAX),caspase-3(CASP3),collagen type IIα1 chain(COL4A2),glycyl-tRNA synthetase(GARS),glial fibrillary acidic protein(GFAP),legumain(LGMN),mucin-4(MUC4),N-myc downstream-regulated gene 1 protein(NDRG1),with ratios to internal controls in the normal group of 1.67,2.06,1.76,2.16,1.53,1.87,1.24,1.61,0.42,0.56,respectively;and there is a potential functional association between GFAP,CASP3,and BAX proteins.Conclusion:In DR mice retinas,there are abnormal changes in the expression of a large number of apoptosis-related proteins.i TRAQ technology can effectively screen out key apoptosis proteins,among which GFAP,CASP3,and BAX may have adverse effects on the progression of DR by participating in the apoptosis process.The application of i TRAQ technology can provide new technical support for proteomic research on apoptosis proteins.

Attribution of Maize Yield Increase in China to Climate Change and Technological Advancement Between 1980 and 2010

Crop yields are affected by climate change and technological advancement.Objectively and quantitatively evaluating the attribution of crop yield change to climate change and technological advancement will ensure sustainable development of agriculture under climate change.In this study,daily climate variables obtained from 553 meteorological stations in China for the period 1961-2010,detailed observations of maize from 653 agricultural meteorological stations for the period 1981-2010,and results using an Agro-Ecological Zones（AEZ） model,are used to explore the attribution of maize（Zea mays L.） yield change to climate change and technological advancement.In the AEZ model,the climatic potential productivity is examined through three step-by-step levels：photosynthetic potential productivity,photosynthetic thermal potential productivity,and climatic potential productivity.The relative impacts of different climate variables on climatic potential productivity of maize from 1961 to 2010 in China are then evaluated.Combined with the observations of maize,the contributions of climate change and technological advancement to maize yield from 1981 to 2010 in China are separated.The results show that,from 1961 to 2010,climate change had a significant adverse impact on the climatic potential productivity of maize in China.Decreased radiation and increased temperature were the main factors leading to the decrease of climatic potential productivity.However,changes in precipitation had only a small effect.The maize yields of the 14 main planting provinces in China increased obviously over the past 30 years,which was opposite to the decreasing trends of climatic potential productivity.This suggests that technological advancement has offset the negative effects of climate change on maize yield.Technological advancement contributed to maize yield increases by 99.6%-141.6%,while climate change contribution was from-41.4%to 0.4%.In particular,the actual maize yields in Shandong,Henan,Jilin,and Inner Mongolia increased by 98.4,90.4,98.7,and 121.5 kg hm^（-2） yr^（-1） over the past 30 years,respectively.Correspondingly,the maize yields affected by technological advancement increased by 113.7,97.9,111.5,and 124.8 kg hm^（-2） yr^（-1）,respectively.On the contrary,maize yields reduced markedly under climate change,with an average reduction of-9.0 kg hm^（-2） yr^（-1）.Our findings highlight that agronomic technological advancement has contributed dominantly to maize yield increases in China in the past three decades.
