Urban green space for human well-being and biodiversity : Do people and birds favour the same?

Angelstam, Mikael January 2013 (has links)
Urban green space has been proven by the field of environmental psychology to have high value for human well-being. Green space is also important for biodiversity. However, the management of urban green space is commonly focused on present aesthetic values and not on the level of naturalness and its consequences for humans and biodiversity. This study compares the green space situation in relation to human well-being and biodiversity in Lviv, Ukraine and Stockholm, Sweden. By sampling urban green space gradients, from unnatural to natural, as well as collecting data about visiting people and bird taxa in those areas, comparisons between these two response variables and the level of naturalness were made. The results show correlations between the level of naturalness and the social structure of human visitors as well as to the bird taxa present. The results thus indicate that both human well-being and biodiversity is positively related to the level of naturalness of green space. Since more and more people live in urban areas decision-makers should leave sufficient amounts of green space, for the inhabitants’ well-being, both people and other species, in physical planning. Given generally low levels of green space in urban settings, areas for recreation and rehabilitation should be enhanced further.

A naturalidade na tradução: quem garante? / The naturalness in translation and fluency of a text

Alvamar Helena de Campos Andrade Lamparelli 24 September 2007 (has links)
Este estudo se baseou em dados extraídos de um corpus paralelo composto por textos originais em inglês de artigos da Revista National Geographic, suas respectivas traduções publicadas em português na National Geographic Brasil, e os textos traduzidos antes da revisão para publicação. O objetivo foi cotejar os três textos a fim de identificar, na tradução, elementos que promovem a produção de um texto natural e fluente, que reflete o uso mais corrente na língua. Sua inserção no âmbito da lingüística de corpus se deu por essa permitir um estudo lingüístico descritivo e não prescritivo da língua e por se voltar não só para as palavras, estruturas ou usos possíveis na língua mas também o que é provável que ocorra, isto é, a diferença entre o que os falantes podem dizer e o que na verdade dizem. Esse cotejo possibilitou o levantamento de aspectos lingüísticos que afetam a naturalidade e fluência do texto, como a fraseologia típica na língua de chegada, suas colocações naturais, suas próprias expressões fixas, que refletem um modo preferido de se expressar de cada comunidade lingüística. Esses aspectos estão intimamente relacionados à convencionalidade, que abrange aquilo que é consolidado pelo uso, constituindo muitas vezes fonte de dificuldade ao \"tradutor ingênuo\" que pode não perceber que dentre formas possíveis existe aquela mais provável de ocorrer. Dentre os elementos levantados, selecionou-se a tradução dos advérbios terminados em *ly em inglês, nem sempre traduzidos por advérbios terminados em *mente em português, procurando compreender essa opção dentro do âmbito da convencionalidade. Essas opções nem sempre são ilustradas em dicionários, constituindo a pesquisa baseada em corpora, tanto paralelos quanto monolíngües, um recurso valioso ao tradutor seja para mostrar estratégias empregadas por outros tradutores profissionais como para conscientizá-lo de um uso consagrado na língua. / This study was based on data collected from a parallel corpus composed of original texts in English of articles from National Geographic magazine, and their respective translations in Portuguese as published in National Geographic Brazil and the texts translated before their revision for publication. The aim was to compare the three texts in order to identify, in translation, elements that enable the production of a text which sounds natural and fluent, reflecting the current use by the speakers. Corpus Linguistics was chosen as an approach for the research since it allows a descriptive rather than a prescriptive study of the language and is typically concerned not only with what words, structures or uses are possible in a language, but also with what is probable, likely to occur, the difference between what the speakers can say and what they actually say. This comparison brought to light linguistic features which might affect naturalness and fluency of a text, as the typical phraseology in the target-language, its natural collocations and its own fixed expressions, which reflect a preferred way of a community of saying things. These aspects are closely related to conventionality, which encompasses that which is attested by the use, and represent precisely where the difficulties lie for the \"innocent translator\", who might not notice that among a range of possible forms there is one which is more likely to occur. Among the elements found, one was particularly investigated, namely, the translation of adverbs ending in *ly in English , not always translated by adverbs ending in *mente in Portuguese, with a view to understand this option within the idea of conventionality. These options are not frequently displayed in dictionaries, which makes corpus-based research , either using parallel corpora or monolingual corpora, an invaluable resource to translators, in eliciting strategies employed by other professional translators and in bringing awareness to an attested use in language.

Perception of micro-expressions in animated characters with different visual styles

Tianyu Hou (11812172) 20 December 2021 (has links)
<div> <p>The purpose of this research was to examine the perception of micro-expressions in animated characters with different visual styles. Specifically, the work reported in this thesis sought to examine: (1) whether people can recognize micro-expressions in animated characters, (2) whether there are differences in recognition based on the character visual style (stylized versus realistic), (3) the extent to which the degree of exaggeration of micro-expressions affect the perceived naturalness and intensity of the animated characters’ emotion, and (4) whether there are differences in effects on perceived naturalness and intensity based on the character visual style. The research work involved two experiments: a recognition study and an emotion rating study. A total of 275 participants participated in both experiments. In the recognition study, the participants watched eight micro-expression animations representing four different emotions (happy, sad, fear, surprised). Four animations featured a stylized character and four a realistic character. For each animation, subjects were asked to identify the character’s emotion conveyed by the micro-expression. Results showed that all four emotions for both characters were recognized with an acceptable degree of accuracy. The recognition rates of the stylized character were 84.73% for happiness, 88.73% for sadness, 60.73% for fear, and 83.64% surprise. The recognition rates of the realistic character were 87.37% for happiness, 82.94% for sadness, 69.62% for fear, and 77.13% for surprise. In the emotion rating study, participants watched two sets of eight animation clips (16 clips in total). Eight animations in each set featured the character performing both macro- and micro-expressions, the different between these two sets was the exaggeration degree of micro-expressions (normal vs exaggerated). Participants were asked to recognize the character’s true emotion (conveyed by the micro-expressions) and rate the naturalness and intensity of the character’s emotion in each clip using a 5-point Likert scale. Findings showed that the <b>degree of exaggeration of the micro-expressions </b>had a significant effect on <b>emotion’s</b> <b>naturalness rating</b>, <b>emotion’s</b> <b>intensity rating</b>, and <b>true emotion recognition</b> and the <b>character visual style</b> had a significant effect on emotion’s <b>intensity rating</b>. Emotion type, participant gender and participant animation experience also had significant effects on perception of the micro-expression.</p> </div> <br>

Etická hlediska a možné společenské dopady dobrovolné bezdětnosti / Ethical aspects and possible social effects of free childlessness

Haškovcová, Eva January 2019 (has links)
This thesis maps Czech social and expert discussions on the theme of child-free people childnessness. It is directed on those aspect with implicit ethical content. Subsequently it chooses the most often argument, what are discussed in the ethical reflection. To be child-free is more and more becoming phenomenon, in the Czech Republic especially in the last thirty years. In spite of that it is considered to be rather as alternative life style, what is often exposed to moral evaluation, with mostly negative tone. The criticism of the child-free people can be sumarized into two main streams, when the first one directs on the social impact of the declining birth rates, the second one focuses on personal features of the child-free people, to whom it reprehends either defective hierarchy of values or unnaturalness of their behavior. These two groups of arguments are confronted with the philosophical concept of inclinationes naturales (natural tendencies) of Thomas Aquinas.

THE EFFECT OF FACIAL EXPRESSION ASYMMETRY ON THE BELIEVABILITY, APPEAL, AND NATURALNESS OF VIRTUAL AGENTS

Klay Max Hauser (17543814) 04 December 2023 (has links)
<p dir="ltr">With the recent virtualization of our everyday lives and the development of intelligent AI technology, realistic virtual agents are becoming a useful tool for research, education, and entertainment. With virtual agents customized content can be created and individualized for specific users. However, virtual agents are only effective tools if they can form a connection with the individual. To form a connection the virtual agent must be believable.</p><p dir="ltr">The literature review evaluates topics of virtual agent believability, appeal, and naturalness and how they relate to asymmetry in facial expression animation. The literature suggests that asymmetries can affect the perception of virtual agents. Additionally, it suggests that emulating human behavior is beneficial to increasing perception of believability, appeal, and naturalness.</p><p dir="ltr">In this study we evaluated the effects of facial expression asymmetry on the believability, appeal, and naturalness of virtual agents. To do this we ran an online perception study with students at Purdue University. We found, in brief, that facial expression asymmetries do have significant effect on the believability, appeal, and naturalness of a virtual agent compared to animations that do not include facial expression asymmetries.</p>

The standard model to the Planck scale

Allison, Kyle F. January 2014 (has links)
The lack of direct evidence for physics beyond the SM at the LHC has led some to reevaluate the need for such physics to solve the hierarchy problem. Instead, the notion that the SM, or something like it, is valid up to the Planck scale and that technical naturalness is sufficient for solving the hierarchy problem has been suggested. This thesis examines minimal extensions of the SM that address its phenomenological and theoretical shortcomings while avoiding new physics between the electroweak and Planck scales that introduces a hierarchy problem. This thesis first studies two issues with the vMSM - an extension of the SM by three right-handed neutrinos - and their possible solutions. The first issue is the tension between dark matter production in the nuMSM and constraints from the Lyman-alpha forest data. To avoid this tension, the vMSM is extended by a Higgs singlet &Phi; and neutrino dark matter is produced through the decays of &Phi; rather than through left-right neutrino mixing. It is shown that the hierarchical parameters of this model can arise from symmetries broken at or near the Planck scale for two specific examples: one in which &Phi; stabilizes the electroweak vacuum and one in which &Phi; is a light inflaton. The second issue pertains to Higgs &xi;-inflation. In the vMSM, a large non-minimal coupling &xi; of the Higgs to gravity gives inflation but leads to a possible violation of perturbative unitarity below the inflationary scale. A study of Higgs &xi;-inflation with M<sub>h</sub> &simeq; 125-126 GeV, for which the Higgs self-coupling &lambda; runs to small values near the Planck scale, is carried out. It is shown that small &lambda; can significantly reduce &xi; required for inflation, but &xi; cannot be small enough to address the possible unitarity issue. For small &lambda;, a new region of Higgs &xi;-inflation with a large tensor-to-scalar ratio r that is consistent with BICEP2 is discovered. This thesis then studies the technical naturalness and cosmology of a model that addresses the strong CP problem. It is shown that a classically scale invariant DFSZ invisible a&xi;on model with a Peccei-Quinn scalar S, whose couplings to the SM are ultra-weak, can solve the strong CP problem and generate electroweak symmetry breaking via the Coleman-Weinberg mechanism. The ultra-weak couplings of S are natural due to an underlying appro&xi;mate shift symmetry. The model contains a light pseudo-Goldstone dilaton that can be consistent with cosmological bounds while the a&xi;on can be the dark matter of the universe. Finally, a summary of the thesis is presented and future research topics are suggested.

Trajectoire de restauration des marais intertidaux : réponse du necton à la dépoldérisation dans l’estuaire de la Gironde / Restoration trajectory of intertidal marshes : nekton response to tidal restoration in the Gironde estuary

Lechêne, Alain 14 December 2017 (has links)
Dégradés par plusieurs siècles d’endiguement et menacés par les effets du changement climatique, les marais intertidaux européens font aujourd’hui l’objet d’un nombre croissant de restaurations par rétablissement des marées sur d’anciennes zones endiguées, suivant une tendance générale appelée dépoldérisation. Cette thèse décrit la trajectoire de restauration des marais intertidaux à partir des communautés de necton (i.e., poissons et crustacés décapodes), sur la base de deux sites dépoldérisés accidentellement dans l’estuaire de la Gironde : le marais de Mortagne et l’île Nouvelle. L’évolution du necton dans les marais dépoldérisés est caractérisée à travers une approche synchronique à l’échelle de la mosaïque des habitats estuariens. La composition du necton dans les marais dépoldérisés est en grande partie similaire à celles des milieux intertidaux naturels et se différencie nette-ment des marais endigués, où les espèces exotiques d’eau douce prospèrent. Les marais restaurés apparaissent particulièrement attractifs pour le mulet porc, Liza ramada. La distribution des traits fonctionnels au sein des communautés de poissons révèle un changement de structure fonctionnelle au cours de la dépoldérisation, le temps de restauration étant inféré à partir d’un gradient de naturalité des habitats estuariens. En particulier, la spécialisation, la dispersion et la richesse fonctionnelle augmentent au cours de la restauration. Concernant l’évolution des règles d’assemblage, aucune tendance claire ne se dégage : les patrons diffèrent selon les traits fonctionnels.La dynamique temporelle de la composition des communautés de necton dans l’un des sites dépoldérisés montre une succession de trois phases au cours des quatre années suivant la restauration. Un changement plus abrupt concernant l’abondance de certaines espèces et la structure fonctionnelle des communautés est identifié au milieude la seconde phase, moins de deux ans après la dépoldérisation. La cinétique de transformation des communautés est probablement ralentie par le drainage incomplet du site dans les premiers temps de la dépoldérisation. Les résultats de cette thèse permettent de mieux comprendre la trajectoire de restauration des marais intertidaux, sans intervention humaine, tout en soulignant les atouts et les limites de certains modèles théoriques utilisés en écologie de la restauration. / European intertidal marshes have greatly declined during the past centuries because of land claim andhave recently been threatened by the effects of climate change. In recent years, an increasing number of tidal resto-ration projects have been implemented, following a global trend termed de-embankment. This thesis describes therestoration trajectory of tidally restored marshes from the response of nekton (i.e., fish and decapod crustaceans)based on two storm-breached study sites in the Gironde estuary : the Mortagne marsh and the Nouvelle island.Nekton assemblage composition of tidally restored marshes was described through a whole-estuary approach en-compassing natural, restored and dyked habitats. Nekton assemblages of tidally restored marshes showed highcompositional similarity with natural intertidal habitats and greatly departed from dyked marshes. Dyked marsheswere characterized by high occurrence of freshwater exotic taxa. Tidally restored marshes seemed particularly at-tractive for the thin-lipped grey mullet, Liza ramada. The functional traits’ distribution within fish communities revealeda change in functional structure in the course of restoration using the naturalness state of habitats as a proxy forrestoration time. Most notably, functional specialization, dispersion and richness increased with restoration time.No clear pattern of change was observed in community assembly over time ; trends chiefly varied with respect totraits. Temporal trends in one of the restored sites revealed three phases in the first four years of tide restoration.The abundance of several species and the community functional structure changed more steeply in the midst ofthe second phase, less than two years following tide restoration. Community turnover was probably delayed dueto incomplete drainage of the site in the early stages of restoration. The results of this thesis lead to a better un-derstanding of the restoration trajectory of tidal marshes without human intervention and highlight the strengths andweaknesses of some theoretical models used in restoration ecology.

Translating pragmatic markers : or whatever you want to call them

Estling Hellberg, Sanna January 2013 (has links)
This study analyses the translation of pragmatic markers from English into Swedish. The source text that was translated and used as a basis for the study is an article called “Black Books”, which was published in the British music magazine Prog in January 2013. The study is limited to question tags, general extenders and single-word pragmatic markers. It aims to investigate how these types of pragmatic markers can be translated in a dynamic and natural way, as well as how a careful analysis can facilitate the search for appropriate translation equivalents. Previous research and theories were used to determine the functions of the pragmatic markers in the source text, and the translation choices made on the basis of these findings were supported by corpus searches in the English-Swedish Parallel Corpus and Korp. The study revealed that because of the different ways in which pragmatic functions are expressed in English and Swedish, almost none of the pragmatic markers in the source text could be translated directly into Swedish. Formally equivalent solutions such as tja as a translation of well were generally considered too unnatural. While the study is too small to provide any general guidelines, it shows how a careful analysis may help the translator find more dynamically equivalent and natural solutions in the form of, for instance, other Swedish pragmatic markers, modal particles, adverbs and conjunctions.

N-Grams as a Measure of Naturalness and Complexity

Randák, Richard January 2019 (has links)
We live in a time where software is used everywhere. It is used even for creating other software by helping developers with writing or generating new code. To do this properly, metrics to measure software quality are being used to evaluate the final code. However, they are sometimes too costly to compute, or simply don't have the expected effect. Therefore, new and better ways of software evaluation are needed. In this research, we are investigating the usage of the statistical approaches used commonly in the natural language processing (NLP) area. In order to introduce and evaluate new metrics, a Java N-gram language model is created from a large Java language code corpus. Naturalness, a method-level metric, is introduced and calculated for chosen projects. The correlation with well-known software complexity metrics are calculated and discussed. The results, however, show that the metric, in the form that we have defined it, is not suitable for software complexity evaluation since it is highly correlated with a well-known metric (token count), which is much easier to compute. Different definition of the metric is suggested, which could be a target of future study and research.
