Subsistemas políticos : a (r)existência da política de assistência social no Estado do Paraná /

Faria, Everton Henrique January 2020 (has links)
Orientador: Carla Gandini Giani Martelli / Resumo: Neste trabalho foi analisado a capacidade do Conselho Estadual de Assistência Social do Paraná de impactar as agendas governamentais como subsistema político na consolidação do Sistema Único de Assistência Social (SUAS) no Estado, analisando as formas de interação entre Estado-sociedade e a articulação desempenhada pelo Conselho como subsistema político na consolidação da Política Estadual de Assistência Social como política pública mediante os projetos políticos do executivo estadual entre os anos de 2011 a 2018. O pressuposto da pesquisa está na concepção que a existência dos Conselhos Gestores e das Conferências de Políticas Públicas contribuem efetivamente para a consolidação das políticas públicas em um Estado Democrático de Direito inferindo significativamente nas agendas governamentais, além de ofertarem um repertório de interação entre Estado-sociedade como subsistemas políticos que articulam atores e instituições na apresentação de escolhas e alternativas. Parte-se da dimensão de que interesses outros, que não os coletivamente acordados nas Conferências e encaminhados pelos Conselhos Gestores, influenciam a incorporação ou não das deliberações na agenda do Poder Público do Estado. Com a utilização de técnicas qualitativas e quantitativas de pesquisa concluiu-se que mesmo diante de vários desafios, a atuação do Conselho foi capaz de impactar as agendas governamentais na consolidação do SUAS no Estado, articulando, propondo e deliberando diferentes assuntos importantes...

The research assumption is in the conception that the existence of the Managers Councils and the Public Policy Conferences effectively contribute to the consolidation of public policies in a Democratic State, implying significantly in the governmental agendas, besides offering a repertoire of interaction between state-society as political subsystem that articulates actors and institutions presenting choices and alternatives. It starts from the dimension of others interests, that are not collectively agreed upon the Conferences and forwarded by the Managers Council, influencing the incorporation or not from the deliberations in the agenda of the Public State of Power. Using qualitative and quantitative techniques, we concluded that even before many challenges, the Council’s performance was capable of impacting the governmental agendas in the consolidation of the SUAS in the State, through articulation, proposing and deliberating different important subjects to the public pol...

Open Source implementace IMS / Open Source IMS implementations

Ježek, Jiří January 2020 (has links)
The diploma thesis deals with open source implementations of IMS technology. The theoretical part describes the functioning of IMS and its architecture, including the protocols used, the process of registration and connection establishment, as well as potential security threats to IMS systems. Two open source IMS projects were selected, Open IMS Core and Project Clearwater, on which the work is focused. In its next part, the diploma thesis deals with the description of selected open source IMS projects, this part also includes a description of the implemented security of both projects and a detailed procedure of system installation with any necessary configuration. In its practical part, the diploma thesis focused on performance testing of selected projects using the Abacus 5000 hardware tester. First, initialization tests were performed, which verified the possibility of communication between the tester and the tested projects. Subsequently, it was possible to perform performance testing of selected projects. In performance testing, emphasis is placed on system stability, performance in the area of call set-up speed and response time of SIP messages and speed of user registration in the network, at different load levels. The systems have been tested for both call set-up and user registration. Part of the testing is also the implementation of the flood DoS inviteflood attack and the system's response to the increasing intensity of the attack. The last chapter is devoted to the comparison of selected IMS projects, where the test results are clearly presented. This chapter is partly based on publicly available information, such as the technical documentation of individual projects and possibly publicly available mailing lists. Part of the diploma thesis is also a laboratory task in which the student tries to work with Open IMS Core. The laboratory task focuses on the process of creating a user and his registration in the IMS network, establishing a call between individual users and internal routing in IMS networks. The task focuses mainly on signaling processes within the implemented tasks.

IP Multimedia Subsystem / IP Multimedia Subsystem

Bendíček, Martin January 2008 (has links)
This Master’s thesis deals with IMS architecture problems. This thesis describes its creation and progress, also structure of this architecture is mentioned. Text of this thesis describes function of the most important parts of the architecture, such as Proxy-CSCF, Interrogating-CSCF, Serving-CSCF and HSS. IMS architecture uses SIP protocol for establishment, maintenance and closing session and Diameter protocol for network management functions. That is why this thesis also describes characteristics of these two protocols. Next part of the thesis is focused on Open-source platform Open IMS Core and its installation. Open IMS Core platform was developed for testing IMS technologies within an internal project at the Fraunhofer Institute FOKUS in Berlin. Nowadays it is used by major part of vendors and providers for testing their products and services. As a main theme of this thesis, there was made a simple network, which consists of three users. This network is established on fundamentals of IMS and it was made in Open IMS Core. So in one chapter is outlined a process of its creation. There is described a process of adding a user list to database server HSS. In the next part there are mentioned some information about setup of virtual IMS terminal. Eventually there are shown some possibilities of how to catch traffic in the network. In this chapter there are also state diagrams, which describe a process of registration of IMS terminal and also a process of establishment, maintenance and closing session.

P/Q Type Calcium Channel Cav2.1 Defines a Unique Subset of Glomeruli in the Mouse Olfactory Bulb

Pyrski, Martina, Tusty, Mahbuba, Eckstein, Eugenia, Oboti, Livio, Rodriguez-Gil, Diego J., Greer, Charles A., Zufall, Frank 04 September 2018 (has links)
Voltage-gated calcium (Cav) channels are a prerequisite for signal transmission at the first olfactory sensory neuron (OSN) synapse within the glomeruli of the main olfactory bulb (MOB). We showed previously that the N-type Cav channel subunit Cav2.2 is present in the vast majority of glomeruli and plays a central role in presynaptic transmitter release. Here, we identify a distinct subset of glomeruli in the MOB of adult mice that is characterized by expression of the P/Q-type channel subunit Cav2.1. Immunolocalization shows that Cav2.1+ glomeruli reside predominantly in the medial and dorsal MOB, and in the vicinity of the necklace glomerular region close to the accessory olfactory bulb. Few glomeruli are detected on the ventral and lateral MOB. Cav2.1 labeling in glomeruli colocalizes with the presynaptic marker vGlut2 in the axon terminals of OSNs. Electron microscopy shows that Cav2.1+ presynaptic boutons establish characteristic asymmetrical synapses with the dendrites of second-order neurons in the glomerular neuropil. Cav2.1+ glomeruli receive axonal input from OSNs that express molecules of canonical OSNs: olfactory marker protein, the ion channel Cnga2, and the phosphodiesterase Pde4a. In the main olfactory epithelium, Cav2.1 labels a distinct subpopulation of OSNs whose distribution mirrors the topography of the MOB glomeruli, that shows the same molecular signature, and is already present at birth. Together, these experiments identify a unique Cav2.1+ multiglomerular domain in the MOB that may form a previously unrecognized olfactory subsystem distinct from other groups of necklace glomeruli that rely on cGMP signaling mechanisms.

L’homéostasie idéelle. Comprendre la stabilité de l’accès aux soins des étrangers irréguliers en France et aux États-Unis (1970-2016) / The belief homeostasis. Understanding the stability of access to care for unauthorized immigrants in France and in the United States (1970-2016)

Moncada, Marie 27 May 2019 (has links)
Comment comprendre la stabilité de l’accès aux soins des étrangers irréguliers en France et aux États-Unis, de 1970 à 2016, au vu des controverses et des réformes dont fait l’objet cet accès ? Cette thèse dégage deux hypothèses : d’une part, l’action publique française serait soumise à des rétroactions négatives, d’autre part, sa consœur étasunienne serait verrouillée par un noyau dur des croyances. L’analyse mixte, qualitative et quantitative, est effectuée à l’aide du logiciel NVivo sur un matériau provenant des groupes d’intérêt (680 fichiers en France, 881 aux États-Unis), de la presse (15 625 et 16 970), du législatif (1 366 et 1 110) et de l’administration (190 et 105). Une centaine d’entretiens affine les résultats.Cette analyse aboutit à la création d’un pendule d’homéostasie idéelle dévoilant trois activités du noyau dur des croyances : le verrouillage idéel (autocensure) et les rétroactions positive (autorenforcement) et négative (autocorrection). Ainsi, si les États-Unis font l’objet d’un verrouillage idéel, c’est bien les rétroactions négatives, voire positives, qui caractérisent le cas français. En revanche, ces pays ont tous deux un noyau dur qui leur est propre. Le noyau français, d’origine catholique, est ainsi tolérant envers l’infraction et privilégie l’égalité. À l’inverse, le noyau étasunien, d’origine protestante, est peu indulgent envers la transgression des normes et favorise la liberté. / How to understand the stability of the access to care for unauthorized immigrants in France and in the United States, from 1970 to 2016, regarding the controversies and the reforms this access is subjected to? This PhD dissertation uses two hypotheses: on one hand, negative feedbacks would control the French policy; on the other hand, a deep core belief seems to stabilize the US one. A mixed analysis (qualitative and quantitative) is done with the NVivo software on data written by interest groups (680 files in France, 881 in the United States), the press (15 625 and 16 970), the Parliament (1 366 and 1 110) and the administration (190 and 105). A hundred of interviews refined the results.This analysis ends in a belief homeostasis pendulum highlighting three activities of the deep core beliefs: a belief locking (self-censorship), a positive feedback (self-reinforcing) and a negative feedback (self-correcting). In this sense, the US policy is subjected to a belief locking while its French counterpart is dominated by negative and, to a lesser extent, positive feedbacks. But these two countries have their own deep core beliefs. The French deep core, originated from Catholicism, is tolerant towards infringement and favors equality. On the contrary, the US deep core, deriving from Protestantism, is less lenient towards breach and opts for liberty.

Vehicle Conceptualisation, Compactness, and Subsystem Interaction : A network approach to design and analyse the complex interdependencies in vehicles

Abburu, Sai Kausik January 2023 (has links)
The conventional approach to vehicle design is restrictive, limited, andbiased. This often leads to sub-optimal utilisation of vehicle capabilities and allocated resources and ultimately entails the repercussions of designing andlater on an using an inefficient vehicle. To overcome these limitations, it is important to gain a deeper understanding of the interaction effects at component,subsystem, and system level. In this thesis, the research is focused on identifying appropriate methods and developing robust models to facilitate the interaction analysis. To scrutinise and identify appropriate methods, criteria were developed.Initially, the Design Structure Matrix (DSM) and its variations were examined.While DSM proved to be fundamental for capturing interaction effects,it lacked the ability to answer questions about the structure and behaviour ofinteractions and to predict unintended effects. Therefore, network theory wasexplored as a complementary method to DSM which was capable of providing insights into interaction structures and identifying influential variables. Subsequently, two criteria were established to identify subsystems significant to interaction analysis: high connectivity to other subsystems and multidisciplinary composition. The traction motor was observed to satisfyboth criteria as it had higher connectivity with other subsystems and was composed of multiple disciplines. Therefore, a detailed model of an induction motor was developed to enable the interaction analysis. The induction motor model was integrated into a cross-scalar design tool.The tool employed a two-step process: translating operational parametersto motor inputs using Newtonian equations and deriving physical attributes,performance characteristics, and performance attributes of the motor. Comparing the obtained performance characteristics curve against existing studiesvalidated the model’s reliability and capabilities. The design tool demonstrated adaptability to different drive cycles and the ability to modify motor performance without affecting operational parameters. Thus validating the capability of the design tool to capture cross-scalar and intra-subsystem interaction effects. To examine inter-subsystem interaction, a thermal model of an inverter was developed, capturing temperature variations in the power electronics based on motor inputs. The design tool successfully captured interaction effects between motor and inverter designs, highlighting the interplay with operational parameters. Thus, this thesis identifies methods for interaction analysis and develops robust subsystem models. The integrated design tool effectively captures intra-subsystem, inter-subsystem, and cross-scalar interaction effects. The research presented contributes to the overarching project goal of developing methods and models that capture interaction effects and in turn serve as a guiding tool for designers to understand the consequences of their design choices. / Det konventionella tillvägagångssättet för fordonsdesign är restriktiv, begränsat och partiskt. Detta leder ofta till en suboptimal användning av fordonets kapacitet och tilldelade resurser och innebär i slutändan att konsekvenserna blir att använda ett ineffektivt fordon. För att övervinna dessa begränsningar är det viktigt att få en djupare förståelse för interaktionseffekterna på komponent-, delsystem- och systemsnivå. I denna avhandling fokuserar forskningen på att identifiera lämpliga metoder och utveckla robusta modeller för att underlätta interaktionsanalysen. För att granska och identifiera lämpliga metoder utvecklades kriterier. Till att börja med undersöktes Design Structure Matrix (DSM) och dess variationer. Medan DSM visade sig vara grundläggande för att fånga interaktionseffekter, saknade den förmågan att besvara frågor om interaktionsstrukturer och beteende samt förutsäga oavsiktliga effekter. Därför utforskades nätverksteori som en kompletterande metod till DSM, vilket kunde ge insikter i interaktionsstrukturer och identifiera inflytelserika variabler. Därefter etablerades två kriterier för att identifiera delsystem som är betydelsefulla för interaktionsanalysen: hög anslutning till andra delsystem och mångdisciplinär sammansättning. Dragkraftmotorn observerades uppfylla båda kriterierna eftersom den hade högre anslutning till andra delsystem och var sammansatt av flera discipliner. Därför utvecklades en detaljerad modell av en induktionsmotor för att möjliggöra interaktionsanalysen. Induktionsmotormodellen integrerades i ett tvärskaligt designverktyg. Verktyget använde en tvåstegsprocess: att översätta operativa parametrar till motorinsatser med hjälp av Newtons ekvationer och härleda fysiska egenskaper, prestandakaraktäristik och prestandaattribut hos motorn. Jämförelse av den erhållna prestandakaraktäristikkurvan med befintliga studier validerade modellens tillförlitlighet och förmågor. Designverktyget visade anpassningsbarhet till olika körcykler och förmågan att modifiera motorprestanda utan att påverka operativa parametrar. Detta validerade designverktygets förmåga att fånga tvärskaliga och intra-subsystem interaktionseffekter. För att undersöka inter-subsysteminteraktion utvecklades en termisk modell av en inverter, som fångade temperaturvariationer i kraftelektroniken baserat på motorns styrning. Designverktyget fångade framgångsrikt interaktionseffekter mellan motor- och inverterdesign och belyste samspelet med operativa parametrar. Därmed identifierar denna avhandling metoder för interaktionsanalys och utvecklar robusta delsystemmodeller. Det integrerade designverktyget fångar effektivt intra-subsystem-, inter-subsystem- och tvärskaliga interaktionseffekter. Den presenterade forskningen bidrar till det övergripande projektets mål att utveckla metoder och modeller som fångar interaktionseffekter och i sin tur fungerar som ett vägledande verktyg för designers att förstå konsekvenserna av sina designval. / <p>QC 231003</p>
