Subliminal Perception, Microgenesis, and Personality
1986
Publisher Summary In person perception, the interpersonal dimension is useful, as is implicated in communicating personal contents. The problem of consciousness is intimately connected with that of knowledge based on subjective experience and perception by means of which it is mediated. This chapter presents the theories that incorporate the subject–object relationships into a comprehensive observational framework. They also emphasize the coherence of subject and environment. The perceiver is viewed as an active subject; the rhythmic properties of all living phenomena are highlighted. The long-term effect of “selective visual exposure” in the early stages of development upon functional cell…

Epidemioloģisku situāciju uztveres telpiskā monitoringa rīka izveide
2021
Darba mērķis ir pētīt kā cilvēku uzskati, par kontaktu ar potenciāli saslimošu, atšķiras no ekspertu viedokļa, lai apzinātos kādi ir iespējamie veidi kā labāk samazināt atšķirību šajos uzskatos, kā uzlabot jau esošas sistēmas, kā monitorēt cilvēku attieksmi pret pandēmiju un atvieglot šo procesu. Par darba pamatu aptaujāto ikdienas cilvēku un ekspertu viedokļu salīdzinājumam, kalpos kursa darbā izveidota aptauja, kurā ir ievākta 32 cilvēku atbildes. Izmantojot šo aptauju, tiks ievāktas atbildes no cilvēkiem ar zināšanām par epidemioloģiju jeb ekspertiem un salīdzināts abu grupu viedoklis. Darba rezultātā tiks noskaidrots vai aptaujāto ikdienas cilvēku un ekspertu viedokļi, par epidemioloģis…
From an epoxide monomer toolkit to functional PEG copolymers with adjustable LCST behavior.
2011
The lower critical solution temperature (LCST) behavior of novel poly(ethylene glycol) (PEG)-based copolymers bearing multiple functional groups, obtained by anionic ring-opening (co)polymerization (AROP), has been investigated. Variable comonomer ratios of ethylene oxide (EO) and the corresponding oxiranes isopropylidene glyceryl glycidyl ether (IGG), ethoxyl vinyl glycidyl ether (EVGE), allyl glycidyl ether (AGE), or N,N-dibenzyl amino glycidyl (DBAG), particularly designed to implement functional groups at the PEG backbone, were found to influence the LCST behavior. Sharp transitions from translucent to opaque solutions, comparable to other well-established stimuli-responsive polymers, w…
Observing animals and humans : dogs target their gaze to the biological information in natural scenes
2020
Background This study examines how dogs observe images of natural scenes containing living creatures (wild animals, dogs and humans) recorded with eye gaze tracking. Because dogs have had limited exposure to wild animals in their lives, we also consider the natural novelty of the wild animal images for the dogs. Methods The eye gaze of dogs was recorded while they viewed natural images containing dogs, humans, and wild animals. Three categories of images were used: naturalistic landscape images containing single humans or animals, full body images containing a single human or an animal, and full body images containing a pair of humans or animals. The gazing behavior of two dog populations,…
Objekta formas un novietojuma ietekme uz fiksācijas disparitāti
2022
Bakalaura darbs ir uzrakstīts latviešu valodā uz 29 lapaspusēm. Tas satur 18 attēlus un 43 atsauces uz literatūras avotiem. Darba mērķis bija novērtēt stimulu formas un novietojuma ietekmi uz fiksācijas disparitāti. Pētījumā piedalījās 10 dalībnieki vecumā no 20-37 gadiem. Izmantojot acu kustību iekārtu Tobii Pro fusion, tika novērtēta objektīvā fiksācijas disparitāte 3 dažādiem stimuliem. Katrs stimuls tika demonstrēts 13 ekrāna pozīcijās. Pētījumā tika noskaidrots, ka fiksācijas stimula veidam nav būtiskas ietekmes uz fiksācijas disparitāti, bet stimula novietojumam ir ietekme uz fiksācijas disparitāti.
Dual Stimuli-Responsive Polysaccharide Hydrogels Manufactured by Radiation Technique
2022
Featured Application Stimuli-responsive hydrogels encompassing biobased polymers are anticipated for utilization in various fields, starting from drug delivery systems through temporal actuators and water reservoirs to biodegradable microelements and nutrient delivery depots. This paper describes the results of the radiation-induced crosslinking of polysaccharides modified with hydroxypropyl and carboxymethyl functional groups, hydroxypropylcellulose (HPC) and carboxymethylcellulose (CMC), respectively, without and with poly(ethylene glycol) diacrylate (PEGDA) as a crosslinking agent, to obtain dual stimuli-responsive hydrogels. The gels were characterized in terms of water uptake and gel f…
Salivary protein profiles and sensitivity to the bitter taste of caffeine.
2011
WOS: 000298381900008; International audience; The interindividual variation in the sensitivity to bitterness is attributed in part to genetic polymorphism at the taste receptor level, but other factors, such as saliva composition, might be involved. In order to investigate this, 2 groups of subjects (hyposensitive, hypersensitive) were selected from 29 healthy male volunteers based on their detection thresholds for caffeine, and their salivary proteome composition was compared. Abundance of 26 of the 255 spots detected on saliva electrophoretic patterns was significantly different between hypo- and hypersensitive subjects. Saliva of hypersensitive subjects contained higher levels of amylase…
