Etická dilemata v sociální práci z pohledu sociálních pracovníků ve veřejné správě (sociálních kurátorů) / Ethical dilemmas in social work from point of view of social workers in public administration (probation officers)

Volák, Michal January 2017 (has links)
The thesis is focuse on professional ethics and ethical dilemmas in the work of a social worker in public administration / probation officer for adults. The main object was to find out what social workers consider as ethical dilemmas, how they are experiencing these situations, which strategies they choose to cope with these and what sources of support do they have. The overview part of the thesis is focused on a topic of values of social work and values of social workers. Overview part gives more attention to conception of justice and social justice, with which, among other documents, the codes of ethics work as one of the fundamental values of social work. It examines the professional values of social work by analyzing ethical documents - ethical codes. Research part of the thesis is based on qualitative research carried out through in-depth interviews with social workers in public administration. The objection of the research was to find out what professional situations social workers consider as ethical dilemmas, how they experience them, what strategies they choose to manage these situations and what sources of support do they have. The main findings of the research point out that social workers as ethical dilemmas perceive mainly situations when it is difficult for them to make decisions in...

Kvantová teorie mezinárodních vztahů: Modelování strategické interakce pomocí kvantové teorie prevděpodobnosti / Quantum Theory of International Relations: Modeling Strategic Interaction with Quantum Probability Theory

Tesař, Jakub January 2018 (has links)
Recent results from cognitive psychology suggest that human behavior can be, in some situations, better described by laws known from physical quantum theory. This work responds to this development and seeks to answer the question of how quantum models of cognition and decision-making can contribute to our understanding of the social world. We introduce the approaches to the application of quantum theory in social sciences - quantum consciousness, quantum reasoning and quantum metaphor and further develop the second, in the context of strategic interaction in game theory. We show that the quantum model corresponds to both the psychological intuition and many empirically known anomalies such as the order effect, disjunction effect, or context effect. In this work, we derive a specific model of strategic interaction between two players, and we test it in the experimental Prisoner's Dilemma game. The model is based on the rational choice theory, which is nevertheless re-defined when it is shown how the strategic choice is changed if the quantum probability (C*-algebra) is used as the underlying theory instead of classical probability (σ-algebra). The results obtained support the quantum model and showed a different representation of the game among various groups of players. The quantum model of...

Vliv zadavatelů reklamy na obsah médií na příkladu motoristických časopisů / Influence of Advertisers on Media Coverage on the example of Motoring Magazines

Formánek, Vojtěch January 2020 (has links)
This thesis examines the influence of advertisers on the content of printed motoring magazines through the method of quantitative content analysis. The thesis asks whether an increasement of advertising can or can not influence media's reporting on advertisers' products. The thesis examines three Czech printed motoring magazines: Svět motorů, Automobil revue and auto motor a sport. The theoretical part deals with the dual-market topic, in other words the theory of two types of media's customers: paying readers and paying advertisers. They can - and according to the theory they often do - differ in their interests. The advertiser is interested in showing his products in the media in the best possible light, on the contrary, the reader is interested in being informed as objectively as possible. The theoretical part is based mainly on McQuail (2009) and Jirák and Köpplová (2015), who deal, inter alia, with the dilemma of two customers. Part of the theory is devoted to several other research which have examined the same topic; e. g. in the context of Italian fashion magazines. The work itself is based on research questions that ask about a correlation between the amount of advertising and amount (and tonality) of editorial content devoted to the advertisers as well as a possible influence of...

Pipková, Irena January 2014 (has links)
The work involves comparingethical values in the general population without serious damage to the general health, and in pacients within overal disease where i tis clear that the scale of values of the two groups are different. From futher examinations came some additional insights /see Chapter 4 d/ and chapter 5 work/. Results and conclusions are in line with Anglo-Saxon literature/ European and overseas/ and our own experience with treating pacients. No medical industry can not fully ensure full health of pacients. There is a set of values focused on specific medical professions and their own core values. These parameters set values based on many aspects of professional decision meking. And those serve to assess the pacientś needs. How to treat and the doctorś own medical approach to the pacient with severe overal ilness correspondens to the hierarchy of ethical values in Ozar-Sokol scheme.

Dilemmes familiaux de la prise en charge de la maladie d’Alzheimer : principes, relations et émotions / Family dilemma about taking care of Alzheimer's disease : principles, relationships and emotions

Miceli, Pamela 08 April 2013 (has links)
À partir d'un modèle d’analyse alliant les apports théoriques des sociologies de l'aide familiale et des émotions, nous analysons l'expérience de la prise en charge familiale de la maladie d’Alzheimer à travers trois dilemmes : l’exercice de la toilette du malade, le recours aux structures d'accueil et d’hébergement et l’intervention dans sa vie privée. Ces dilemmes sont appréhendés au prisme de trois registres d'interprétation, d'action et de justification : un registre principiel, un registre relationnel et un registre émotionnel. Nos analyses éclairent ainsi la singularité plurielle des expériences et des implications des proches familiaux des malades. / From an analytical model, combining the theoretical contributions of the sociology of family support and the sociology of emotions, we analyze the experience of family care of Alzheimer’s disease through three dilemmas: the exercise of the patient’s toilet, the use of reception and housing structures by families and intervention in the patient’s private life. Theses dilemmas are understood through the prism of three registers of interpretation, action and justification: a register of principles, a relational register and an emotional register. Our analysis light up the plural singularity of experiences and implications of relatives of Alzheimer’s patients. / A partir de un modelo analítico que combina las contribuciones teóricas de las sociologías del apoyo familiar y de las emociones, se analiza la experiencia de la atención familiar de la enfermedad de Alzheimer a través de tres dilemas: el ejercicio del baño del enfermo, el uso de centros de día y residencias, y la intervención en su vida privada. Estos dilemas se entienden bajo el prisma de tres registros de interpretación, acción y justificación: un registro de principios, un registro relacional y un registro emocional. Nuestros análisis aclaran la singularidad plural de las experiencias e implicaciones de los familiares de los enfermos.

"O avunculado na Antropologia Evolutiva: uma abordagem intercultural" / "The avunculate in the evolutionary anthropology: a cross cultural survey"

Maia, Antonio Carlos do Amaral 28 February 2007 (has links)
O presente trabalho se propõe a compreender a variabilidade cultural humana em relação à organização da família por meio das teorias darwinianas da seleção natural e da seleção sexual, e se encontra baseado em evidências vindas da comparação de dados etnográficos. Pretende-se demonstrar que existe uma alteração marcante no comportamento de todos os envolvidos nas relações familiares quando mudam as regras de herança. Essas alterações assim ocorrem porque as regras de herança direcionam o Investimento Parental Masculino (MPI), ora ao sobrinho, ora ao filho. A hipótese apresentada é a de que a variação do MPI modifica de maneira compreensível e previsível as relações familiares em organizações matrilineares e patrilineares. A prova da hipótese será feita por meio da aplicação do método intercultural com pesquisa etnográfica nos bancos de dados do HRAF, e utilizando-se da amostra PSF. Os resultados do presente trabalho indicarão que em sociedades em que o tio tem uma relação afetuosa com seu sobrinho, o marido espanca a mulher; e quando o pai se relaciona de maneira indulgente e amigável com seu filho, irmãos e irmãs se evitam, alinhando esses fatos de maneira que possam ser coerentemente entendidos com a teoria sociobiológica. A riqueza cultural, o sem número de costumes, as tradições, os tabus, as normas explícitas ou ocultas, os aparatos de coerção de toda sorte, as regras sobre herança, casamento, dote, preço da noiva, divisão de trabalho, enfim, todas as regras observadas em todos os agrupamentos humanos podem ser explicadas à luz das seguintes teorias: a) da “seleção de consangüíneos" (Hamilton, 1963), b) do “altruísmo recíproco" (Trivers, 1971), c) do “investimento parental e seleção sexual" (Trivers, 1972), e d) do “conflito entre prole e parentais" (Trivers, 1974). / The present work proposes to account for cultural variability in connection to human family organization, through Darwin’s theories of natural selection and sexual selection. It is also founded on evidence based on the comparison of ethnographic data of diverse human societies. It intends to demonstrate that there is a significant alteration in the behavior of family members when the rules of inheritance of wealth change. These alterations are triggered because the rules of inheritance dictate the MPI – Male Parental Investment – sometimes in the nephew and sometimes in the son. The hypothesis is that this variation in MPI (male investment in either the nephew or the son) modifies family relations in matrilineal and patrilineal organizations in a predictable manner. The role played by MPI in determining family tensions will be shown by applying cross cultural analysis to the data obtained from HRAF (Human Relations Area Files), using PSF (Probability Sample Files). The results of the present work show that societies in which the uncle’s relation with his nephew is affectionate, the husband beats the wife; on the other hand, when the father’s relation with his son is indulgent and friendly, brother and sister avoid each other. This variability of behavior can be coherently explained by sociobiological theory. Cultural wealth: the innumerable customs, the traditions, the taboos, the manifest and hidden norms, the apparatus of coercion, the rules of inheritance, marriage, dowry, bride price, the division of labor, in short, all the rules observed in all human groups can be explained in the light of the following theories: a) ‘kinship selection’ (Hamilton, 1963); b) ‘reciprocal altruism’ (Trivers, 1971; Axelrod, 1981); c) ‘parental investment and sexual selection’ (Trivers, 1972); and d) ‘parentoffspring conflict’ (Trivers, 1974).

Dilema do prisioneiro evolucionário Darwiniano e Pavloviano no autômato celular unidimensional: uma nova representação e exploração exaustiva do espaço de parâmetros / Darwinian and Pavlovian Evolutionary Prisoner Dilemma in the One-Dimensional Cellular Automata: a new representation and exhaustive exploration of parameter space

Pereira, Marcelo Alves 11 April 2008 (has links)
O Dilema do Prisioneiro (DP) é o jogo mais proeminente da Teoria dos Jogos devido à emergência da cooperação entre jogadores egoístas. O comportamento de cada jogador depende da estratégia que ele adotada e do seu ganho, que é determinado em função dos parâmetros do DP (T, R, P e S) e do número z de vizinhos com que ele joga. Portanto, a estrutura espacial dos jogadores não é relevante. Em nosso trabalho, utilizamos um autômato celular unidimensional onde cada jogador pode cooperar ou desertar ao interagir, simetricamente, com seus z vizinhos mais próximos. O sistema proposto nos permitiu realizar um estudo exaustivo do espaço de parâmetros para as estratégias evolucionárias Darwiniana (EED) e a Pavloviana (EEP) e compara-las. A geometria unidimensional nos possibilita obter os mesmos resultados dos sistemas em dimensionalidade arbitrária d, além de apresentar várias vantagens em relação a elas. No sistema que propomos os efeitos de borda são menores, exige menos tempo para a execução das simulações numéricas, permite variar o valor de z e é fácil obter uma representação visual da evolução temporal do sistema. Tal visualização simplifica a compreensão das interações entre os jogadores, pois surgem padrões nos agrupamentos de cooperadores/desertores, semelhantes aos pertencentes às classes dos autômatos celulares elementares. O estudo destes padrões nos permite compreender simplesmente a emergência da cooperação ou deserção nos sistemas. A evolução temporal do sistema que adota a EED gera um diagrama de fases muito rico com a presença das fases cooperadora, desertora e caótica. Já para a EEP, obtivemos um novo resultado analítico para as transições de fase, que neste caso são: cooperadora e quasi-regular. O estudo numérico exaustivo determinou as regiões do espaço de parâmetros onde acontecem cada uma das fases, e os efeitos da auto-interação podendo assim validar os resultados teóricos. O estudo do caso particular T = 1, tradicionalmente considerado como trivial, mostrou que ele apresenta comportamentos inusitados. Nossa principal contribuição para o estudo do DP é a obtenção de um novo paradigma. A geometria unidimensional com interação de vizinhos simétricos permitiu a visualização da evolução de padrões de cooperadores e desertores, o cálculo analítico de Tc para a EEP e o estudo de T = 1 para tais sistemas. / The Prisoner Dilemma (PD) is the most prominent game of the Game Theory due to emergency of the cooperation between selfish players. The behavior of each player depends on his/her strategy and the payoff, which is determined in function of the PD parameters (T, R, P and S) and by the number z of neighbors with whom he/she plays. Therefore, the spatial structure of the players does not matter. In our work, we have used a one-dimensional cellular automaton where each player can cooperate or defect when interacting, symmetrically, with his/her z nearest neighbors. The considered system allowed us to carry out an exhaustive exploration of the parameters space for the Darwinian Evolutionary Strategy (EED) and Pavlovian (EEP) and compares them. One-dimensional geometry makes possible to us get the same results of the systems in arbitrary d dimensional networks, besides, it presents some advantages. For the system that we proposed compared to the others dimensional networks, the boundary effects are less present, it needs less time for run the numerical simulations, it allows to vary the z value and is easier to get the visual representation of the system temporal evolution. Such visualization simplifies the understanding of the interactions between the players, therefore patterns appear in the clusters of cooperator/defectors, and these patterns belong to the elementary cellular automata classes. The study of these patterns allows them to understand in an easy way the emergence of the cooperation or defection in the systems. The temporal evolution of the system that adopts the EED yields a very rich phases diagram with the presence of cooperative, defective and chaotic phases. By the other hand, for the EEP, we have got a new analytical result for the phase transitions that in this case are: quasi-regular and cooperative. The exhaustive exploration study determines the regions on the parameters space where happen each phases occurs, and the effect of the self-interaction and thus validate the theoretical results. The study of the particular case T = 1, traditionally considered as trivial one, showed that it presents unusual behaviors, that we will present. Our main contribution for the study of the DP is the attainment of a new paradigm. One-dimensional geometry with interaction of symmetrical neighbors allowed to visualizes the evolution of cooperators and defectors patterns, the analytical result for Tc for the EEP and the study of T = 1 for such systems.

Análise do efeito do investimento inicial no dilema do prisioneiro contínuo iterado simultâneo e alternado na presença e ausência de ruído em diferentes cenários de incerteza: contrapondo as estratégias RTS e LRS por meio da simulação bas / Analysis of the effect of the initial investment in the continuous iterated prisoners dilema with simultaneous and alternating moves in the presence and absence of noise in different scenarios of uncertainty: opposing the RTS and LRS strategies through agent-based simulation

Wu, Marcio Jolhben 11 September 2015 (has links)
O dilema do prisioneiro é geralmente visto como o ponto de partida para entender o problema da cooperação. Em comparação com o dilema do prisioneiro discreto e iterado, poucos estudos existem sobre o dilema do prisioneiro contínuo e iterado. A maioria dos trabalhos que investigaram o dilema do prisioneiro contínuo e iterado concentrou-se no período de 1990 a 2000, não obtendo resultados conclusivos sobre a melhor estratégia a ser adotada neste tipo de jogo. Duas estratégias diferentes se destacam neste tipo de dilema. A primeira é a estratégia RTS (Raise-the-Stakes) de Roberts e Sherrat (1998) que testa o terreno antes de aumentar os investimentos na relação. A segunda deriva do modelo LRS (Linear Reactive Strategies) de Wahl e Nowak (1999a). Esta última estratégia estando em equilíbrio de Nash cooperativo apresenta três características: (i) generosidade, i.e., investir o máximo possível no início da relação de cooperação; (ii) otimismo, i.e., contar com o melhor cenário para as próximas rodadas, e (iii) intransigência. Esta pesquisa tem como objetivo principal contrapor as estratégias RTS e LRS num dilema do prisioneiro contínuo e iterado, na presença e ausência de ruído, com jogadas simultâneas e alternadas e para diferentes valores do parâmetro w (probabilidade de interagir novamente). Restringimos a nossa análise a um conjunto de seis estratégias: ALLC, ALLD, TFT, RTS, LRS e RTSM. O método utilizado foi o da simulação baseada em agente (ABM) no formato de torneios, semelhante ao de Axelrod (2006), Roberts & Sherratt (1998), Nowak & Sigmund (1992) e Nowak & Sigmund (1993). Utilizamos o software Netlogo e documentamos todo o processo da concepção e construção do modelo por meio da ferramenta TRACE (TRAnsparent and Comprehensive model Evaludation). Os resultados mostram que as estratégias mais cooperativas são mais favorecidas quando o jogo consiste em jogadas alternadas ao invés de simultâneas. A estratégia RTS teve melhor desempenho em jogos simultâneos para valores intermediários de w, na presença ou ausência de ruído. Por sua vez, a estratégia LRS teve melhor desempenho nos jogos simultâneos, na presença ou ausência de ruído, ou alternados e na presença de ruído, em ambos os casos para valores grandes de w / The prisoner\'s dilemma is generally seen as the starting point for understanding the problem of cooperation. In comparison with the discreet and iterated prisoner\'s dilemma, few studies exist on the continuous iterated prisoner\'s dilemma. Most of the works that have investigated the continuous iterated prisoner\'s dilemma has concentrated in the period from 1990 to 2000, not getting conclusive results on the best strategy to be adopted in this type of game. Two different strategies stand out in this kind of dilemma. The first is the RTS strategy (Raise-the-Stakes) of Roberts and Sherrat (1998) that tests the ground before increasing investment in the relationship. The second is the model deriva LRS (Linear Reactive Strategies) de Wahl and Nowak (1999a). This last strategy being in Nash equilibrium cooperative presents three characteristics: (i) generosity, i.e., investing as much as possible at the beginning of the cooperation relationship; (ii) optimism, i.e., rely on the best scenario for the next rounds, and (iii) intransigence. This research has as main goal to reconcile opposing RTS strategies and LRS in a continuous iterated prisoner\'s dilemma, in the presence and absence of noise, with simultaneous moves and alternate and for different values of the parameter w (probability of interacting again). We restrict our analysis to a set of six strategies: ALLC, ALLD, TFT, RTS, LRS and RTSM (halfway between RTS and LRS). The method used was the agent-based simulation (ABM) in tournament format, similar to that of Axelrod (2006), Roberts (1998), Sherratt & Nowak & Sigmund (1992) and Nowak & Sigmund (1993). We use the NetLogo software and document the whole process of design and construction of the tool model TRACE (TRAnsparent and Comprehensive model Evaludation). The results show that most strategies are more favoured unions when the game consists of alternating plays rather than simultaneous. The RTS strategy had better performance in simultaneous games for intermediate values of w, in the presence or absence of noise. In turn, the IRS strategy had better performance when simultaneous games, in the presence or absence of noise, or switched, and in the presence of noise, in both cases, for large values of w
