The enviroment is something that is important for living things, especially humans. The enviroment is used by humans to meet the needs of life, if it does not take care of the enviroment properly it will cause enviromental problems. There are many environmental problems, one of which is the waste problem. The problem of waste is a problem that often occurs in urban areas, one of which is in the city of Ternate. The Ternate City Government needs tochoose the right solution to overcome the problems that occur due to waste, but before making a solution it is necessary to know how the public’s perception of waste transportation in Ternate City is. The research method is descriptive quantitative using a questionnaire distributed to respondents as a research instrument. The sampling technique used in this research is random sampling with a sample of 400 respondents in four districts in Ternate City. The sample of each sub-district amounted to 100 respondents. Data analysis using interpreted percentages. The results showed that the public’s perception of waste transportation in Ternate City was good.

Previous studies have demonstrated the involvement of spatial codes in the representation of time and numbers. We took advantage of a well-known spatial modulation (prismatic adaptation) to test the hypothesis that the representation of time is spatially oriented from left to right, with smaller time intervals being represented to the left of larger time intervals. Healthy subjects performed a time-reproduction task and a time-bisection task, before and after leftward and rightward prismatic adaptation. Results showed that prismatic adaptation inducing a rightward orientation of spatial attention produced an overestimation of time intervals, whereas prismatic adaptation inducing a leftward shift of spatial attention produced an underestimation of time intervals. These findings not only confirm that temporal intervals are represented as horizontally arranged in space, but also reveal that spatial modulation of time processing most likely occurs via cuing of spatial attention, and that spatial attention can influence the spatial coding of quantity in different dimensions.

Les théories qui modélisent la perception spatiale chez l'adulte s'accordent à postuler l'existence de liens forts entre la perception et l'action(James, 1892 ; Poincaré, 1902 ; Gibson, 1979 ; Noe, 2004). Une vaste collection de données montre également que ces liens sont présents dans le développement ontogénétique. Ce travail de thèse vise à examiner les implications de tels liens dans le développement de la perception spatiale et d'en identifier les déterminants chez l'enfant. Nous avons mené une série d'expériences, basée sur l'utilisation des paradigmes d'atteignabilité et d'amorçage visuomoteur, autour de la problématique de l'élaboration et l'utilisation des représentations perceptives et sensorimotrices dans la perception spatiale. Nous avons mené ces expériences chez une population d'adultes et d'enfants âgées de 7 à 13 ans avec l'objectif d'évaluer la trajectoire développementale de la perception spatiale. Les résultats obtenus mettent en évidence des discontinuités dans les trajectoires développementales des différentes tâches proposées. Nous avons mis en évidence les marqueurs de ces changements développementaux dans les performances des tâches d'atteignabilité, d'imagerie motrice et également d'amorçage visuomoteur. Nous interprétons ces résultats comme relevant d'un changement qualitatif de la perception spatiale durant cette période. D'une manière générale, les travaux présentés dans cette thèse apportent des données nouvelles sur le développement de la perception spatiale chez l'enfant, et sont mis en relation avec la littérature en psychologie et en neurosciences du développementSpatial perception and motor skills : a developmental approach

La pseudonegligence observee chez les normaux (bowers et heilman, 1980) consiste a repondre a gauche du centre objectif quand on demande de partager des lignes horizontales par le milieu. Certains l'expliquent par la nature spatiale de la tache qui, en activant l'hemisphere d, entrainerait un "surdimensionnement" de la partie g du stimulus. Mais son instabilite souligne aussi la puissance du biais d'orientation vers la d. D'autres pensent que le sens de l'exploration determine celui des deviations, ou invoquent un amorcage de l'attention du cote ou debute l'exploration. Nous avons teste l'hypothese de l'existence dans cette tache de composantes sensorielle et motrice s'exercant en sens inverse. Nos resultats ne confirment pas la pseudonegligence et ne montrent pas de difference entre les sujets aveugles et voyants. Chaque main devie dans l'hemiespace controlateral. D'autre part, si on impose toujours le meme sens d'exploration, les deviations suivent ce sens. Mais, lorsqu'on amorce lateralement l'attention avant l'exploration, les erreurs sont attirees du cote de l'amorcage. La discussion porte sur la theorie d'activation hemispherique et sur l'hypothese d'un decalage du referentiel egocentreBowers and heilman (1980) observed that when righthanded adults were asked to locate, in the hapic modality, the midpoint of a horizontal line, both hands tended to deviate to the left of the true midpoint. This error, called "pseudoneglect" by reference to the rightward error of patients suffering from right posterior brain lesions, was also observed in vision and has been explained by hemispheric activation theories. Because bisection is spatial in nature, it would activate the right hemisphere and would therefore induce a left lateral shift of attention. In our research on bisection in the haptic modality of normal blindfolded and totally blind adults, we first replicated bowers and heilman's results (sampaio & philip, 1991). But further studies failed to confirm the existence of pseudoneglect. Actually, each hand tended to deviate in the contralateral space. In addition, when the direction of exploration of the line to be bisected was constrained (from left-to-right only, or from right-to-left), the responses were deviated in the direction of the arm movement. Finally, attentional priming of one end of the stimulus tended to deviate the subjective midpoint in the direction of the lateral cue. These results are discussed in relation to hemispheric activation theories and to the hypothesis assuming changes in the egocentric reference frame

Full textAbstract:
Progressive addition lenses (PALs) are an increasingly preferred mode for the correction of presbyopia, gaining an increased share of the prescription lens market. Sales volumes are likely to increase over the next few years, given the increasing cohort of presbyopic patients in the population. This research investigated adaptation to PAL wear, investigating head movement parameters with and without progressive lenses in everyday visual tasks, and examined symptoms of spatial distortions and illusory movement in a crossover wearing trial of three PAL designs. Minimum displacement thresholds in the presence and absence of head movement were also investigated across the lens designs.
Experiment 1 investigated head movements in two common visual tasks, a wordprocessing copy task, and a visual search task designed to replicate a natural environment task such as looking for products on supermarket shelving. Head movement parameters derived from this experiment were used to set head movement amplitude and velocity in the third experiment investigating minimum displacement thresholds across three PAL designs. Head movements were recorded with a Polhemus Inside Track head movement monitoring system which allows real time six degrees of freedom measurement of head position. Head position in azimuth, elevation and roll was extracted from the head movement recorder output, and data for head movement angular extent, average velocity (amplitude/duration) and peak velocity were calculated for horizontal head movements
Results of the first experiment indicate a task dependent effect on head movement peak and average velocity, with both median head movement average and peak velocity being faster in the copy task. Visual task and visual processing demands were also shown to affect the slope of the main sequence of head movement velocity on head movement amplitude, with steeper slope in the copy task. A steeper slope, indicating a faster head movement velocity for a given head movement amplitude, was found for head movements during the copy task than in the search task. Processing demands within the copy task were also shown to affect the main sequence slopes of velocity on amplitude, with flatter slopes associated with the need for head movement to bring gaze to a specific point. These findings indicate selective control over head movement velocity in response to differing visual processing demands.
In Experiment 2, parameters of head movement amplitude and velocity were assessed in a group of first time PAL wearers. Head movement amplitude, average and peak velocity were calculated from head movement recordings using the search task, as in Experiment 1. Head movements were recorded without PALs, on first wearing a PAL, and after one month of PAL wear to assess adaptation effects. In contrast to existing literature, PAL wear did not alter parameters of head movement amplitude and velocity in a group of first time wearers either on first wearing the lenses or after one month of wear: this is due to task related effects in this experiment compared to previous work. Task demand in this experiment may not have required wearers to use the progressive power corridor to accomplish identification of visual search targets, in contrast to previous studies where experimental conditions were designed to force subjects to use the progressive corridor.
In Experiment 3, minimum displacement thresholds for random dot stimuli were measured in a repeated measures experimental design for a single vision lens as control, and three PAL designs. Thresholds were measured in central vision, and for two locations in the temporal peripheral field, 30° temporal fixation and 10° above and below the horizontal midline. Thresholds were determined with and without the subjects' head moving horizontally in an approximate sinusoidal movement at a frequency of about 0.7 Hz. Minimum displacement thresholds were not significantly affected by PAL design, although thresholds with PALs were higher than with a single vision lens control. Head movement significantly increased minimum displacement threshold across lens designs, by a factor of approximately 1.5 times. Results indicate that the local measures of minimum displacement threshold determined in this experiment are not sensitive to lens design differences. Sensitivity to motion with PAL lenses may be more a global than a localized response. For Experiment 4, symptoms of spatial distortion and illusory movement were investigated in a crossover wearing trial of three PAL designs, and related to optical characteristics of the lenses. Peripheral back vertex powers of the PALs were measured at two locations in the right temporal zone of the lenses, 15.6 mm temporal to the fitting cross, and 2.7 m above and below the horizontal to the fitting cross. These locations corresponded to the zones of the lenses through which minimum displacement thresholds were measured in the previous experiment. The effect of subjects' self movement on symptoms is able to discriminate between PAL designs, although subjective symptoms alone were not related to the lens design parameters studied. Subjects' preference for one PAL design over the other designs studied in this experiment is inversely related to the effect on subject movement on their symptoms of distortion. An optical parameter, blur strength, derived from the power vector components of the peripheral powers, may indicate preference for particular PAL designs, as higher blur strength values are associated with lower lens preference scores.
Head movement amplitude and velocity are task specific, and are also influenced by visual processing demands within tasks. PALs do not affect head movement amplitude and velocity unless tasks are made demanding or performed in less natural situations designed to influence head movement behaviour. Both head movement and PALs have large effects on minimum displacement thresholds; these effects may be due in part to complexity of the subjects' task within the experiment. Minimum displacement thresholds however were not influenced by PAL design. The most sensitive indicator for subject's preference of PALs was the effect of subjects' self movement on their perception of symptoms, rather than the presence of actual symptoms. Blur strength should be further investigated for its role in PAL acceptance.

In everyday life, our body gets in contact with multiple tactile stimuli from the outside world. How our somatosensory system identifies and localises these multiple stimuli entering in contact with our body surface, is the general framework to which the researches of the present thesis belong. Tactile stimuli on our body can be spatially coded and represented by using multiple reference frames. Touch is initially encoded into a sensory-space within primary somatosensory map and then further stages of processing can represent the location of tactile event with respect to the overall body structure (body-space) or to the outside world (external-space). In the present thesis we report first a series of behavioural experiments aimed at investigating which spatial reference frame is adopted in a special context of sensory stimulation, namely the double simultaneous stimulation (DSS). Then, we used functional magnetic resonance (fMRI) as a tool for delineating the neural bases of the cognitive processes sub-serving the elaboration and representation of concurrent stimuli for conscious tactile perception. In a first behavioural study using the tactile DSS paradigm, we defined the spatial coding used by observers when tactile stimuli are delivered with different fingers combinations (i.e., within vs. between hands) and hand postures (i.e., hands palm-down vs. palm-up). In a second behavioural work we tested the influence of different visual modulations (e.g., seeing body parts or objects) and visual-proprioceptive conflict (e.g., seeing body parts in a different position with respect to one adopted by the participant) on the spatial representation of touch. Furthermore, we investigated the effect of changes to the visual structural morphology of a body part on the spatial representation of touch. Finally, using a fMRI adaptation paradigm for touches at the fingers, we aimed to define the neural bases of tactile perception in a repeated stimulations context. In particular, we assessed the mutual interaction between tactile stimuli located at body parts that are clearly distinct in terms of the body-space (e.g., left and right index fingers), but proximal in terms of neural representations (due to some bilateral responses of the somatosensory cortices).

Full textAbstract:
To interact with the environmet, it is crucial to have a clear space representation. Several findings have shown that the space around our body is split in several portions, which are differentially coded by the brain. Evidences of such subdivision have been reported by studies on people affected by neglect, on space near (peripersonal) and far (extrapersonal) to the body position and considering space around specific different portion of the body. Moreover, recent studies showed that sensory modalities are at the base of important cognitive skills.
However, it is still unclear if each sensory modality has a different role in the development of cognitive skills in the several portions of space around the body. Recent works showed that the visual modality is crucial for the development of spatial representation.
This idea is supported by studies on blind individuals showing that visual information is fundamental for the development of auditory spatial representation. For example, blind individuals are not able to perform the spatial bisection task, a task that requires to build an auditory spatial metric, a skill that sighted children acquire around 6 years of age.
Based these prior researches, we hypothesize that if different sensory modalities have a role on the devlopment of different cognitive skills, then we should be able to find a clear correlation between availability of the sensory modality and the cognitive skill associated.
In particular we hypothesize that the visual information is crucial for the development of auditory space represnetation; if this is true, we should find different spatial skill between front and back spaces.
In this thesis, I provide evidences that spaces around our body are differently influenced by sensory modalities. Our results suggest that visual input have a pivotal role in the development of auditory spatial representation and that this applies only to the frontal space. Indeed sighted people are less accurated in spatial task only in space where vision is not present (i.e. the
back), while blind people show no differences between front and back spaces. On the other hand, people tend to report sounds in the back space, suggesting that the role of hearing in allertness could be more important in the back than frontal spaces. Finally, we show that natural training, stressing the integration of audio motor stimuli, can restore spatial cognition, opening new possibility for rehabilitation programs. Spatial cognition is a well studied topic.
However, we think our findings fill the gap regarding how the different availibility of sensory information, across spaces, causes the development of different cognitive skills in these spaces. This work is the starting point to understand the strategies that the brain adopts to maximize its resources by processing, in the more efficient way, as much information as possible.

La thèse est organisée en deux parties. Une première partie présente la littérature consacrée à l'étude de la cognition spatiale. Cette présentation s'inscrit dans une approche interdisciplinaire (psychologie, neurophysiologie, sciences de l'information, éthologie, philosophie). Il est notamment analysé comment les différences interindividuelles en cognition spatiale sont décrites par ces différentes disciplines. Une attention particulière sera donnée à des différences qualitatives de traitement, c'est-à-dire aux stratégies mises en oeuvre pour réaliser des traitements visuo-spatiaux. On analysera également les différences dans la qualité des représentations construites à partir d'une exploration d'un espace tridimensionnel. Il sera essayé de dresser un cadre interprétatif intégratif des différences constatées sur la base de la théorie neurologiquement plausible de Kosslyn introduisant la distinction entre un subsystème catégoriel et métrique pour l'encodage des relations spatiales. L'hypothèse est émise que l'efficacité de fonctionnement de ces subsystèmes peut constituer un élément explicatif important pour les différences interindividuelles en cognition spatiale. Dans la deuxième partie, on présentera 4 expériences impliquant la mesure de la qualité de l'encodage spatial à l'aide de dispositifs sur support informatique. Un de ces dispositifs est plus spécialement destiné à évaluer la précision de l'encodage spatial et montre la stabilité des différences interindividuelles constatées, ainsi que la relation entre précision d'encodage et performance à des épreuves de type papier-crayon. Il s'avère que cette dernière relation est importante, surtout en ce qui concerne les facteurs spatial et général. Une épreuve d'exploration d'un espace virtuel en 3D permet en plus d'évaluer l'impact de la précision de l'encodage spatial sur l'efficacité de déplacement. Les résultats sont interprétés dans le cadre neurologiquement plausible de la théorie de KosslynThe dissertation is organized in two parts. The first part presents the literature concerning the study of spatial cognition. This representation adopts an interdisciplinary approach (psychology, neurophysiology, information sciences, ethology, philosophy). Of special interest are interindividual differences in spatial cognition as described by these disciplines. Particular attention is payed to qualitative processing differences, i. E. Different strategies for processing of visuo-spatial information. Individual differences in the quality of representations constructed from navigation in a threedimensional space are also analysed. The attempt is made to create an integrative framework of interpretation for the described differences on the basis of the neurologically plausible theory of Kosslyn introducing the distinction between categorical and metric spatial relations encoding. The hypothesis is made that the efficiency of these subsystems may represent an important element in the explanation of interindividual differences in spatial cognition. In the second part, 4 experiences are presented which imply the measurement of the quality of spatial relations encoding with computer-assisted tests. One of these tests measures specifically the precision of spatial relations encoding and shows stability of individual differences, as well as the relation between spatial relations encoding precision and performance on paper and pencil tests. This relation seems important, especially with the spatial and general factors of intelligence. A navigation test in a virtual environment furthermore permits to evaluate the influence of spatial relations encoding precision on wayfinding performance. Results are interpreted in the framework of Kosslyn's neurologically plausible theory of visuo-spatial information processing

Ce travail a pour objet de proposer un nouvel eclairage a la theorie des cadres de reference d'orientation associee aux taches d'identification de formes. Deux courants de recherches, appartenant a la psychologie cognitive generale et a la psychologie differentielle, se sont interesse aux referentiels spatiaux d'orientation, mais il ont rarement ete mis en relation. Ce travail se propose de rapprocher la theorie des cadres de reference, elaboree par les cognitivistes, et l'etude de la dependanceindependance a l'egard du champ (dic) au travers de la vicariance des processus perceptifs. Une revue de la litterature montre l'importance d'une prise en compte conjointe des traitements d'identification et d'orientation et met, egalement, en evidence la necessite de considerer les differences individuelles dans le recours aux references visuelles d'orientation. L'hypothese generale, testee ici, est que le style cognitif des individus aura des repercussions sur la resolution d'une tache d'identification de formes ambigues. Autrement dit, que les resultats classiquement observes d'une relative dependance des sujets aux informations visuelles contextuelles dans les taches d'identification de formes est fonction du degre de dependance des individus a l'egard du referentiel visuel d'orientation. Les travaux empiriques portent sur le role du contexte visuel et l'influence des variations posturales sur la resolution de la tache de kopermann. De facon generale, les resultats vont dans le sens attendu: les sujets reperes sur la base du rft comme dependants a l'egard du referentiel visuel sont ceux qui ont le plus de difficulte a resoudre la tache d'identification. Cependant, cette dependance a l'egard du referentiel visuel peut etre modulee en fonction de la nature du contexte visuel presente et des variations posturales introduites lors de la passation de l'epreuve. L'ensemble de ces resultats amenent a formuler des hypotheses en termes de demandes attentionnelles mais celles-ci sont encore a verifierThe aim of this work is to propose a new point of view of the reference frame theory. Cognitive psychologists and differential psychologists were interested in spatial reference frames but their points of view were rarely associated. This work tried to bring together reference frame theory and cognitive style of field-dependence-independence (fdi). The emphasis was placed on the necessity to take into account orientation and identification processing and individual differences in identification of ambiguous shapes. The general hypothesis was that the cognitive style influence the resolution of identification task when ambiguity was due ambiguous orientation. Field dependent subjects were dependent to visual reference both in identification and orientation tasks. The empirical results were analysed in two directions: the influence of visual context and the effect of modulation of postural balance. Results were congruent with theoretical hypotheses but a last research , concerned pop-out treisman's paradigm, led to re-analyse all the results in terms of visual-spatial attention theory and differential attentional demands

Full textAbstract:
Recently there has been increased interest in how the visual system compensates for gaps in perception due to scotomas (e.g., Ramachandran, 1992). However, it has been difficult to control the placement of the stimuli so that the stimuli are always at the desired retinal location relative to the scotoma. Lettvin (as cited in Ramachandran, 1992) reports that vertically misaligned lines across the physiological blind spot are perceived as being in-alignment. But, Lettvin also reported that horizontal misaligned lines are not perceived as being in-alignment. This study measures the horizontal and vertical alignment threshold of lines across a scotoma by using a scanning laser ophthalmoscope to place the lines at specific retinal locations relative to the scotoma. In addition, this study measures the horizontal and vertical bias in the perceived in-alignment lines to determine the amount of distortion in spatial position across a scotoma. This spatial distortion is often referred to as metamorphopsia, a perception in which objects appear distorted and/or larger or smaller than their actual size. The measurement of metamorphopsia using a vernier acuity task was proposed by Enoch et al. (Enoch, Baraldi et al., 1988), although the technique has been developed for subjects with ocular media opacities and not subjects with scotomas (Lakshminarayanan, Aziz et al., 1992). This study will determine whether subjects with macular scotomas can have spatial position perception that includes a distortion in the bias and/or a higher threshold for in-alignment mapping from object space to perception space.

Full textAbstract:
The aim of the study was to explore the impact of furniture and spatial settings on teachers and students. Drawing on a case study action research approach involving surveys, two primary schools (Frangipani and Jasmine Primary School) within the Sydney Catholic Schools were involved as case study sites. This report provides a summary of the findings of the impact of furniture and spatial settings on teacher efficacy, teacher mind frames, student learning and student engagement as well as perceptions of students on the furniture and spatial settings. In summary, teachers’ perceptions of their mind frames, student learning and engagement increased after the introduction of furniture in the prototype learning environment. For one teacher, the perception of their efficacy did not improve after the implementation of the prototype space and furniture. In terms of students’ perceptions of the furniture, a large proportion of students agreed that they enjoyed learning and are more motivated to learn because of the new furniture. At Jasmine Primary School, a fifth of students felt that they were not motivated to learn because of the new furniture. Further in-depth study is required to find out the underlying reasons for this. Key themes that emerged from the qualitative data on the furniture and spatial settings focus on characteristics of furniture that afforded comfort, improved concentration and auditory qualities, supported collaboration, and capacity for choice. These are important considerations to drive decisions in school designs and furniture purchases. The importance of good furniture in a learning space cannot be underestimated. New learning environments and furniture demand and create new possibilities for teacher practices and student learning. The findings of the study, whilst limited in its scale, provides three crucial considerations relating to the importance of prototyping, professional learning and longitudinal data. These carry ramifications for wider understanding and future research. Future inquiry in these three key areas can provide the much-needed evidence to support schools’ transition into new learning environments.

Full textAbstract:
During the 88th General Session held virtually in May 2021, the World Organisation for Animal Health (WOAH: founded as OIE) Regional Commission for Europe agreed “Long-distance transport of live animals: WOAH’s standards and best practices including societal perception and communication aspects” as the Technical Item I to be presented during the 30th Conference of the Regional Commission in Catania (Italy), from 3 to 7 October 2022. An online questionnaire was designed and distributed to WOAH Members of the Regional Commission for Europe from 21 June to 8 July 2022 (with minor finalisations by 2 August 2022). The persons responsible for completing the questionnaire (of 47 Members in total) were mainly WOAH Delegates, National Focal Points for animal welfare or National Contact Points for long-distance transportation. The qualitative analysis of the information provided was carried out by grouping similar answers and, when proper, the United Nations geoscheme was applied to highlight any spatial clustering of the results. The wide majority of the Members (46 out of 47) declared to have in place specific legislation on animal welfare during transport, and most of them stated to be “generally aligned” with WOAH standards, there are still many countries in the Region where certain crucial requirements are not mandatory. Journey and contingency plans are commonly part of the specific legislation on animal welfare during transport, as well as monitoring and evaluation of the implementation of the legal requirements concerning animal transport by the Competent Authority or other certification bodies. The presence of major gaps in budget and/or available resources and trained personnel was declared by almost half of the responding Members (21 out of 47). Concerning the awareness of the civil society regarding animal welfare issues during transport, 11 Members reported a “low” level of awareness, and they were mostly included in the areas of Southern Europe, Western and Central Asia. The greatest part of Members responding “high awareness” clustered in the Northern and Western Europe geographical areas. Members were also asked to indicate possible WOAH initiatives that could improve the implementation of the standards, and most of them suggested to develop training activities and provide additional guidance through revised and/or new standards in the Terrestrial Animal Health Code and/or through other WOAH documents.

Full textAbstract:
We investigate the effect of domestic armed violence brought about by political instability on the geography of distance frictions in freight mobility and the resulting differential access of regions to global markets. The Colombian transportation system has been found to be impeded by deficiencies in landside transport infrastructure and institutions, and by fragmented political environments. The micro-level analysis of U.S.-bounded export shipping records corroborates that export freight shipping from inland regions is re-routed to avoid exposures to domestic armed violence despite greatly extended landside and maritime shipping distances. We exploit the trajectories of freight shipping from Colombian regions and spatial patterns of violent armed conflicts to see how unstable geopolitical environments are detrimental to freight shipping mobility and market openness. The discrete choice model shows that the shipping flow is greatly curbed by the extended re-routing due to domestic armed violence and that inland regions have restricted access to the global market. The perception of risk and re-routing behavior is found heterogeneous across shipments and conditional to shipment characteristics, such as commodity type, freight value and shipper sizes. The results highlight that political stability must be accommodated for improved freight mobility and export-oriented economic development in the global South.

Abstract. The article dwells upon the Earth remote sensing data as one of the basic directions of Geo-Information Science, a unique source of information on processes and phenomena occurring in almost all spheres of the Earth geographic shell (atmosphere, hydrosphere, lithosphere, etc.). The authors argue that the use of aerospace images by means of the information and communication technologies involvement in the learning process allows not only to increase the information context value of learning, but also contributes to the formation of students’ cognitive interest in such disciplines as geography, biology, history, physics, computer science, etc. It has been grounded that remote sensing data form students’ spatial, temporal and qualitative concepts, sensory support for the perception, knowledge and explanation of the specifics of objects and phenomena of geographical reality, which, in its turn, provides an increase in the level of educational achievements. The techniques of aerospace images application into the modern school practice have been analyzed and illustrated in the examples: from using them as visual aids, to realization of practical and research orientation of training on the basis of remote sensing data. Particular attention is paid to the practical component of the Earth remote sensing implementation into the modern school practice with the help of information and communication technologies.

Full textAbstract:
As part of ARL’s Research Library Impact Framework initiative, the Marston Science Library (MSL) of the University of Florida (UF) George A. Smathers Libraries partnered with the UF Department of Interior Design (IND) to explore how research libraries facilitate innovation, creativity, and problem-solving competencies among their patrons. The MSL-IND team explored a three-tiered hypothesis that included: (1) students’ use of library spaces can contribute to building knowledge and practical applications for library space renovations; (2) student perceptions of space desirability as measured by the Place-based Semantic Differential can be used to indicate gaps in the library space facilitation of creativity; and (3) the creative thought process requires spaces that are diverse, flexible, and under a certain amount of student control. The research team developed a mixed-method study that included a spatial analysis, a survey utilizing an adjective checklist, and several focus groups designed to validate the adjective checklist. The research team analysis of the resulting data identified recommendations related to creating a sense of place, solving for the group by addressing the individual, offering a palette of posture, increasing biophilia, and offering choice and control.

Full textAbstract:
Plant yield largely depends on a complex interplay and feedback mechanisms of distinct hormonal pathways. Over the past decade great progress has been made in elucidating the global molecular mechanisms by which each hormone is produced and perceived. However, our knowledge of how interactions between hormonal pathways are spatially and temporally regulated remains rudimentary. For example, we have demonstrated that although the BR receptor BRI1 is widely expressed, the perception of BRs in epidermal cells is sufficient to control whole-organ growth. Supported by additional recent works, it is apparent that hormones are acting in selected cells of the plant body to regulate organ growth, and furthermore, that local cell-cell communication is an important mechanism. In this proposal our goals were to identify the global profile of translated genes in response to BR stimulation and depletion in specific tissues in Arabidopsis; determine the spatio-temporal dependency of BR response on auxin transport and signaling and construct an interactive public website that will provide an integrated analysis of the data set. Our technology incorporated cell-specific polysome isolation and sequencing using the Solexa technology. In the first aim, we generated and confirmed the specificity of novel transgenic lines expressing tagged ribosomal protein in various cell types in the Arabidopsis primary root. We next crossed these lines to lines with targeted expression of BRI1 in the bri1 background. All lines were treated with BRs for two time points. The RNA-seq of their corresponding immunopurified polysomal RNA is nearly completed and the bioinformatic analysis of the data set will be completed this year. Followed, we will construct an interactive public website (our third aim). In the second aim we started revealing how spatio-temporalBR activity impinges on auxin transport in the Arabidopsis primary root. We discovered the unexpected role of BRs in controlling the expression of specific auxin efflux carriers, post-transcriptionally (Hacham et al, 2012). We also showed that this regulation depends on the specific expression of BRI1 in the epidermis. This complex and long term effect of BRs on auxin transport led us to focus on high resolution analysis of the BR signaling per se. Taking together, our ongoing collaboration and synergistic expertise (hormone action and plant development (IL) and whole-genome scale data analysis (US)) enabled the establishment of a powerful system that will tell us how distinct cell types respond to local and systemic BR signal. BR research is of special agriculture importance since BR application and BR genetic modification have been shown to significantly increase crop yield and to play an important role in plant thermotolerance. Hence, our integrated dataset is valuable for improving crop traits without unwanted impairment of unrelated pathways, for example, establishing semi-dwarf stature to allow increased yield in high planting density, inducing erect leaves for better light capture and consequent biomass increase and plant resistance to abiotic stresses.
