A defesa de territórios pode ser flexível, sendo manifestada apenas quando existirem recursos críticos que limitem o crescimento da população (frequentemente representados pela disponibilidade de alimento) e quando estes forem economicamente defensáveis. Os primatas do gênero Callicebus são geralmente descritos como territoriais, embora esta caracterização baseie-se em estudos focados em apenas três das 30 espécies conhecidas desse gênero diverso de primatas Neotropicais. Ainda, a manifestação de comportamentos relacionados à territorialidade se mostrou bastante variável em estudos anteriores, podendo estar relacionada à curta duração desses trabalhos, os quais não contemplaram os efeitos da variação sazonal de recursos alimentares na manifestação desses comportamentos. Nesse contexto, investigamos o comportamento territorial de Callicebus nigrifrons, analisando a influencia da variação na disponibilidade de frutos sobre este comportamento. Buscamos também analisar o papel das vocalizações de longo alcance, geralmente associadas à defesa conjunta de território, mas que também pode estar relacionada a defesa de parceiros reprodutivos. Para isso monitoramos o comportamento de um grupo habituado de C. nigrifrons ao longo de 20 meses (Novembro/2009 - Junho/2011; 730 horas de observação) paralelamente ao monitoramento da disponibilidade de frutos de 22 espécies zoocoricas consumidas por estes primatas. Adicionalmente, analisamos a estrutura dos cantos de longo alcance de nove grupos de C. nigrifrons e relacionamos a estrutura desses cantos aos contextos nos quais estes são utilizados. Também realizamos experimentos com "playbacks" para investigar a importância das vocalizações de longo alcance na defesa conjunta de territórios e de parceiros. As vocalizações de C. nigrifrons apresentaram estrutura hierárquica, cuja combinação de unidades menores, as silabas, dá origem as frases, que são então combinadas em seqüências mais longas. Estas vocalizações de longo alcance são utilizadas tanto para comunicação entre membros do mesmo grupo, como para comunicação entre grupos vizinhos e, embora sejam compostas por unidades vocais semelhantes (mesmas silabas e frases), apresentam estruturas diferentes associadas a estes diferentes contextos comportamentais. Os cantos utilizados para comunicação entre grupos vizinhos foram utilizados principalmente para defesa de recursos alimentares importantes na dieta desses primatas. Diferente de outros Callicebus, C. nigrifrons não exibiu comportamento de defesa e patrulhamento das bordas de sua área de vida, mas focaram o comportamento de defesa em áreas com recursos alimentares importantes e economicamente defensáveis, como arvores frutíferas. Esse comportamento de defesa, tanto pela emissão de vocalizações de longo alcance, quanto pelo uso de outros comportamentos agressivos, resultaram na expulsão de grupos vizinhos que se aproximassem de sua área de uso, e variou em intensidade de acordo com a disponibilidade de frutos no ambiente. A baixa freqüência de encontros entre nosso grupo focal e grupos vizinhos sugere que os comportamentos adotados por C. nigrifrons são efetivos para garantir o acesso prioritário a recursos alimentares importantes em sua dieta / Abstract: Territoriality is a form of competition in which competitors exclude each other from areas containing resources, the territories. Territorial behaviors are flexible and should be adopted only when there is critical resource shortage (which limits population growth) and when these are economically defensible. Callicebus monkeys are usually described as territorial, although this characterization is based on studies focused on three of the 30 known species of this diverse genus of Neotropical primates. Still, the expression of behaviors related to territoriality showed a variable pattern in previous studies. Part of these variations within Callicebus genus could be a result of the short duration of these studies, which did not contemplate the effects of seasonal variation of food resources on territorial behavior. Here we investigated the territorial behavior of Callicebus nigrifrons, evaluating the influence of fruit availability over it. We also evaluated the role of C. nigrifrons loud calls in intra and extra group communication, as well as on food and mate defense. We thus monitored the behavior of a habituated group of C. nigrifrons over a period of 20 months (November/2009 - June/2011; 730 observation hours in total). In parallel to behavioral data collection we monitored the availability of fruits from 22 species eaten by these primates. We also described the structure of loud calls of nine groups of C. nigrifrons and related the structure of these calls to the contexts in which they were used, and performed playback experiments to test the hypotheses of mate and joint territorial defense. Callicebus nigrifrons loud calls are higher hierarchical structures formed by different small units, the syllables, which are assembled to form phrases, which are then assembled to form long sequences, the loud calls. These calls are used in different contexts, involving the communication within and between groups. Although these calls are composed by basically the same syllable and phrase types, the proportional contribution of the different syllable and phrases and the way they are assembled differ between these different contexts. The loud calls used for extra group communication was more clearly associated to joint resource defense of important food recourses in C. nigrifrons diet, the fruits. Unlike previews studies of Callicebus spp., C. nigrifrons did not show the behavior of patrolling and marking range boundaries, but advertised the occupancy of its range via loud call emissions, especially from places close to important and economically defensible food sources, such as fruits. The intensity of the defensive behavior, via loud call emissions and aggressive approach and repulsion of neighboring groups, increased with fruit availability. The low frequency of inter-group agonistic encounter suggest that territories ownership advertisement by C. nigrifrons are effective in maintaining the priority access to important food resources / Doutorado / Ecologia / Doutora em Ecologia

Southern right whale vocalisations recorded in Walker Bay, South Africa, between June and November 1999, were analysed to investigate the acoustic repertoire, the relationship between calling behaviour and whale presence, the proportions of vocal and silent whales, and of recorded calls from unseen whales, and the evidence for vocal individuality. This marks the first study of right whale vocalisation in South African waters. A simple matrix system with the axes acoustic contour and onset frequency described twelve call types. Analysis of call use over time indicated that some calls, as well as broadband gunshots, clustered strongly in bouts of differing lengths, and that their relative use varied over the season; the repertoire and its classification was compared with other accounts of right whale vocalisation [chapter one]. A generalised linear model explained the variation in the overall call rate in terms of the numbers of whales present, month and wind direction. The overall call rate, for each month and in all wind conditions, rose with increasing whale numbers to a plateau at between ten and fifteen whales, and then declined as whale numbers rose further, suggesting that the social motivation for vocalising was progressively reversed. An inverse linear relationship between call rate per whale and whale abundance was clearly demonstrated over the whole season, indicating that call rates were unreliable as an indicator of whale numbers [chapter two]. A dual-axis, three-element hydrophone array suspended at 5m from floating buoys was designed to assign whale vocalisations to calling whales. The array was calibrated with an overall mean error of 3°. Bearings to calling whales were calculated using correlelograms, and compared with the observed positions of whales. On average 31% of low up (upwardly inflected) calls and 11% of medium and high down (downwardly inflected) calls came from whales not sighted from the boat; up to just under half of the whales sighted from the boat were silent. This indicates the importance of integrating visual and acoustic data when estimating whale numbers [chapter three]. In characterising individuality in vocalisations, we used cluster analysis of acoustic properties of whale calls to derive the Euclidean distances (a measure of similarity) between each possible pair of calls within a continuous recording session. Calls clearly from different whales (distant call pairs) were more dissimilar than calls possibly from one whale (‘close’ call pairs), lending support to the hypothesis of vocal individuality. The similarity between ‘close’ up calls was greatest when the calls were within 0.5 minutes of each other, and declined progressively, up to a separation of 6.5 minutes, as the likelihood of both calls being from one whale declined, indicating individual bout-calling. Medium and high down (downwardly inflected) calls, associated with surface active groups (SAGs), and thought by other researchers to be produced by the focal female, were more similar within any given SAG than when compared across SAGs. This evidence strongly suggests that southern right whales produce individually distinctive vocalisations [chapter four]. / Thesis (PhD)--University of Pretoria, 2010. / Zoology and Entomology / unrestricted

Le recours à l’appel d’offres n’est pas, et n’a jamais été, l’apanage des personnes publiques. Parce que la mise en concurrence de cocontractants potentiels permet d’obtenir le meilleur prix, les personnes privées le pratiquent volontairement pour la réalisation de nombreuses opérations contractuelles : construction immobilière, cession d’entreprise, vente d’immeuble, acquisition de produits et de prestations de service, etc. Familière des praticiens, cette figure du paysage précontractuel est négligée par la doctrine. L’objet de cette étude est de présenter une analyse juridique d’ensemble de l’appel d’offres privé. Celui-ci est susceptible de deux acceptions. Dans la ligne directe de son appellation, il désigne une invitation à soumettre des offres. Il s’agit d’un type de proposition de contracter à part entière, distinct des propositions de contracter traditionnelles que sont l’offre et l’invitation à entrer en pourparlers. À le concevoir ensuite comme une procédure de mise en concurrence de cocontractants potentiels pour la conclusion d’un contrat définitif, l’appel d’offres privé donne naissance à un avant-contrat entre son organisateur et ses participants que l’on ne peut ramener aux catégories d’avant-contrats que connaît le droit positif. La qualification d’avant-contrat imprime à l’appel d’offres privé son régime juridique. Ainsi, les parties s’obligent à organiser et à participer à la procédure de mise en concurrence selon les règles fixées par l’organisateur et de bonne foi. Les comportements consistant à fausser le jeu de la concurrence sont alors sanctionnés pour inexécution contractuelle. / Using private invitation to tender is not, and has never been, the prerogative of public entities. Because the implementation of competition calls between potentials co-contractors in order to achieve the best price, private entities practice it voluntarily to realise numerous contractual transactions : building construction, transfer of company, sale of real property, procurement of goods and service delivery, etc. Well-known by practitioners, this figure of the contractual landscape is neglected by the legal doctrine. The purpose of this study is to represent a global legal analysis of the private tender process. This one might be understood in two different ways. Literally, it designates an invitation to submit offers. It is a type of proposal to contract fully-fledged, which defers from the traditional ways of proposal to contract which are the offer and the invitation to treat. Conceived as a process introducing competition between potentials co-contractors to conclude a definitive contract, private invitation to tender give birth o a preliminary contract between its organiser and participants, which is distinct from the existing preliminary contracts. The qualification of preliminary contract print the private invitation to tender’s legal regime. Thus, parties undertook to organise and participate to the implementation of competition calls regarding the rules established by the organiser in good faith. The behaviours consisting in distorting competition are then subject to sanction on the ground of non-fulfillment of a contractul obligation.

The purpose of this study is to investigate how four different teachers in the social sciences subjects in elementary school work with reading comprehension to support their pupils with reading difficulties. The research questions for this study are: Which structures do the teachers in social sciences subject use to support pupils with reading difficulties? How do the teachers in social sciences subject describe the concept of reading difficulties? What additional support do the pupils with reading difficulties receive? Two methods have been used to answer the research questions. Four teachers were interviewed and observed. Lev Vygotskij’s sociocultural perspective was used for the theoretical point of the study.  The results of this study show that the four teachers all use similar methods to help pupils’ develop their reading skills. They work to develop pupils’ vocabulary range by for example supporting structures such as text calls. When the four teachers described the concept of reading difficulties, they all mentioned dyslexia as a common cause of reading difficulties.  In addition, the four teachers mentioned that pupils receive additional support from special needs teachers who help them.

Att arbeta inom ambulanssjukvården innebär ökad risk för att utsättas för en så kallad kritisk händelse som kan leda till olika stressreaktioner bland annat ångest, akut stressyndrom (ASD), posttraumatiskt stressyndrom (PTSD) och depression. Symptom på dessa reaktioner kan innefatta hjärtklappning, sömn - och koncentrationssvårigheter men också empatitrötthet, vilket påverkar vårdpersonalens förmåga att känna empati med sina patienter och förmågan att vårda dessa på bästa sätt. Avlastande samtal är ett psykologiskt stöd som används för ambulanspersonal i dagsläget som ett försök att motverka olika typer av stressreaktioner.   Syftet var att beskriva kunskapsläget kring avlastande samtal för ambulanspersonal efter att de utsatts för kritiska händelser.   Som metod användes allmän litteraturöversikt med induktiv ansats där 15 vetenskapliga artiklar valdes ut och som besvarade den här studiens syfte. Artiklarna söktes i databaserna CINAHL och PubMed och analyserades med integrerad analys   I resultatet framkom fyra kategorier: utveckling och minskade stressreaktioner, avsaknad av avlastande samtal, negativa upplevelser och informellt kamratstöd.   Som slutsats kan konstateras att det finns ett behov av ökad kunskap och utbildning kring avlastande samtal och stressreaktioner hos ambulanspersonal som utsatts för en kritisk händelse. Den fortsatta forskningen som behövs bör fokusera på en evidensbaserad modell för avlastande samtal. / To work in the field of ambulance care comes with an increased risk to be exposed to a so-called critical incident which can lead to several stress reactions, including anxiety, acute stressdisorder (ASD), posttraumatic stressyndrome (PTSD) and depression. Symptoms of these reactions can include increased heart rate, sleep- and concentration difficulties but also compassion fatigue, which will affect the nursing staff's ability to feel compassion towards their patients and their ability to care for those patients in the best way possible. Relief calls is a form of psychological support that is used for ambulance personnel nowadays as a way of trying to counteract different types of stress reactions.   The aim of this study was to describe the state of knowledge concerning relief calls among ambulance personnel after being exposed to critical incidents.   The method used, was a general literature review with an inductive onset where 15 scientific articles were included that gave answer to the aim of this study. The articles were found in the medical databases CINAHL and PubMed and was analysed using an integrated method.   The result generated four categories: development and reduced stress reactions, lack of relief calls, negative experiences, informal peer-support.   As a conclusion it was found that there is a need for increased knowledge and education concerning relief calls and stress reactions among ambulance personnel that has been exposed to a critical incident. The research needed in the future should focus on finding evidence-based models for relief calls

Video calls have received growing attention since the beginning of the COVID 19 pandemic, accompanied by technological innovations, such as spatial audio or AI for simulating eye contact. The increased use of video calls in personal and professional environments poses opportunities for evaluating and shaping this technology by going beyond the notion of a single user and including people with different cognitive abilities. This study proposes a remote participatory design process with people with learning disabilities (LD), aiming to investigate considerations for the design of video call platforms. In cooperation with NetzStecker, the Office for Inclusive Media Education based in Münster, Germany, a four-stage research through design process is conducted with a group of adults with LD, including online workshops and mobile device-based diary studies. Perceptions and experiences are explored through the lens of phenomenology and lead to a set of design recommendations around the themes of spatiality and communication. Methodological conclusions discuss the challenges of using the medium of study as the principal medium of research and indicate a potential for proximity chats as design spaces.

Bakgrund: Det sker världen över en snabb utveckling av elektronisk hälsa.  Målsättningen med digitalisering och elektronisk hälsa är att underlätta för människor att uppnå god och jämlik hälsa. Distriktssköterskor och sjuksköterskor behöver inneha kunskap och medverka vid utvecklingen av elektronisk hälsa och dess verktyg.  Syfte: Syftet med studien var att belysa faktorer som påverkar distriktssköterskor och sjuksköterskors upplevelse av att använda videosamtal för kommunikation och informationsöverföring med patienter inom primärvården. Metod: Studien genomfördes med kvalitativ design med induktiv ansats. Semistrukturerade intervjuer genomfördes med sju distriktssköterskor och tre sjuksköterskor inom primärvården i Sydöstra Sverige. Datamaterialet analyserades med en kvalitativ innehållsanalys.   Resultat: Analysen resulterade i tre kategorier och sju subkategorier. De tre kategorierna var: Kunskap och resurser, alla deltagare upplevde att teknik var en faktor som påverkade upplevelsen. Både tekniska svårigheter och utvecklingen av teknik påverkade videosamtalet. Videosamtal visade sig kunna vara tidsbesparande. Medverkan och interaktion, videomöten med flera aktörer upplevde flertalet deltagare som opersonliga och riskerade exkludera patienten. Videosamtalets kapacitet, deltagarna gjorde en bedömning i vilka situationer det var lämpligt med videosamtal. Slutsats: Videosamtal är ett bra komplement till telefonsamtal, ger god service och är oftast tidsbesparande men kan sällan ses som ersättning till fysiska besök. Teknik kan vara både en hindrande och underlättande faktor vid kommunikationen och informationsöverföring med patienter. Videosamtal med flera aktörer under en vårdplanering där patienten har hög ålder eller nedsatta sinnesfunktioner är inte lämpligt för patienten enligt distriktssköterskor och sjuksköterskors upplevelse. / Background: There is a worldwide rapid development of electronic health. The goal of digitalization and electronic health is to make it easier for people to achieve good and equal health. District nurses need to have knowledge and participate in the development of electronic health and its tools. Aim: The purpose of the study was to shed light on factors that affect district nurses and nurses' experience of using video calls for communication and information transfer with patients in primary health care. Method: The study was conducted with a qualitative design with an inductive approach. Semi-structured interviews were conducted with seven district nurses and three nurses in primary health care in southeastern Sweden. The data material was analyzed with a qualitative content analysis. Results: The analysis resulted in three categories and seven subcategories. The three categories were: Knowledge and resources, all participants felt that technology was a factor that influenced the experience. Both technical difficulties and the development of technology affected the video call. Video calls proved to be time-saving. Participation and interaction, video meetings with several actors experienced the majority of participants as impersonal and risk of exclusion of the patient. Video call capacity, participants made an assessment in which situations video calls were appropriate. Conclusion: Video calls are a good complement to telephone calls, provide good service and are usually time-saving but can rarely be seen as compensation for physical visits. Technology can be both a hindering and facilitating factor in communication and information transfer with patients. Video conversations with several actors during a care planning where the patient is elderly or has impaired sensory functions is not suitable for the patient according to district nurses and nurses' experience.

The following research examined a survey on the identity and feelings of inclusion among alumni of Loyola Marymount University’s Marriage and Family Therapy with Specialization Training in Art Therapy graduate program. The survey found that a majority of the responding alumni did not feel their identities were represented in multiple aspects of the program, and there was a clear call to action for more representation of diversity. More research on the subject is needed to expand a variety of art therapy programs to better understand implications of art therapy pedagogy on identity, representation, and inclusivity within the art therapy community.

This paper investigates alternative scheduling for game objects in a game engine by using priority based algorithms and comparing different priority assigning methods. Research concerning commercial game engines, game loops, concurrency and scheduling was performed. Three different scheduling algorithms were created and tested using a varying amount of game objects between two different testing scenarios. The results showed that using priority based scheduling gave a slight increase in average frames  per second (FPS) as well as boosting logical update performance of prioritized objects, however overall performance was decreased. The reason this decrease in performance occurred could have been due to the way the scheduler was implemented, and despite the decrease in performance using a priority based scheduling system was considered feasible within certain game engines. / Denna uppsats undersöker alternativa sätt för schemaläggning av spelobjekt i en spelmotor genom att använda prioriteringsbaserade algoritmer och jämföra olika tilldelningssätt för prioritetsmetoder. Forskning gällande kommersiella spelmotorer, ''game loops'', parallellisering och schemaläggning utfördes. Tre olika schemaläggningsalgoritmer skapades och testades med ett varierande antal spelobjekt i två olika testscenarion. Resultaten visade att användning av prioritetsbaserad schemaläggning gav en lätt ökning av det genomsnittliga antalet bilder per sekund (FPS) och gav bättre logikuppdateringsprestanda för prioriterade objekt. Den totala prestandan minskade dock. Anledningen till att denna minskning i prestanda skedde kan bero på hur schemaläggaren implementerades, men trots denna prestandaminskning ansågs schemaläggningssystemet vara möjlig inom vissa spelmotorer.
