DESIGN OF GEODETIC NETWORKS BASED ON OUTLIER IDENTIFICATION CRITERIA: AN EXAMPLE APPLIED TO THE LEVELING NETWORK

We present a numerical simulation method for designing geodetic networks. The quality criterion considered is based on the power of the test of data snooping testing procedure. This criterion expresses the probability of the data snooping to identify correctly an outlier. In general, the power of the test is defined theoretically. However, with the advent of the fast computers and large data storage systems, it can be estimated using numerical simulation. Here, the number of experiments in which the data snooping procedure identifies the outlier correctly is counted using Monte Carlos simulations. If the network configuration does not meet the reliability criterion at some part, then it can be improved by adding required observation to the surveying plan. The method does not use real observations. Thus, it depends on the geometrical configuration of the network; the uncertainty of the observations; and the size of outlier. The proposed method is demonstrated by practical application of one simulated leveling network. Results showed the needs of five additional observations between adjacent stations. The addition of these new observations improved the internal reliability of approximately 18%. Therefore, the final designed network must be able to identify and resist against the undetectable outliers – according to the probability levels

Student midwives' perceptions on the organisation of maternity care and alternative maternity care models in the Netherlands - a qualitative study

BACKGROUND: A major change in the organisation of maternity care in the Netherlands is under consideration, going from an echelon system where midwives provide primary care in the community and refer to obstetricians for secondary and tertiary care, to a more integrated maternity care system involving midwives and obstetricians at all care levels. Student midwives are the future maternity care providers and they may be entering into a changing maternity care system, so inclusion of their views in the discussion is relevant. This study aimed to explore student midwives' perceptions on the current organisation of maternity care and alternative maternity care models, including integrated care. METHODS: This qualitative study was based on the interpretivist/constructivist paradigm, using a grounded theory design. Interviews and focus groups with 18 female final year student midwives of the Midwifery Academy Amsterdam Groningen (AVAG) were held on the basis of a topic list, then later transcribed, coded and analysed. RESULTS: Students felt that inevitably there will be a change in the organisation of maternity care, and they were open to change. Participants indicated that good collaboration between professions, including a shared system of maternity notes and guidelines, and mutual trust and respect were important aspects of any alternative model. The students indicated that client-centered care and the safeguarding of the physiological, normalcy approach to pregnancy and birth should be maintained in any alternative model. Students expressed worries that the role of midwives in intrapartum care could become redundant, and thus they are motivated to take on new roles and competencies, so they can ensure their own role in intrapartum care. CONCLUSIONS: Final year student midwives recognise that change in the organisation of maternity care is inevitable and have an open attitude towards changes if they include good collaboration, client-centred care and safeguards for normal physiological birth. The graduating midwives are motivated to undertake an expanded intrapartum skill set. It can be important to involve students' views in the discussion, because they are the future maternity care providers. (aut. ref.

O estabelecimento de padrões de referência altimétrica utilizando o nivelamento geométrico para a definição de alvos altos e inacessíveis

As estruturas geodésicas altimétricas são fundamentais para os projetos de Engenharia. Neste contexto, pode-se utilizar a tecnologia do nível digital para a determinação de pontos de referência altimétrica através do método do nivelamento geométrico. Outra solução é a utilização da tecnologia da estação total para a determinação de altitudes em pontos situados em locais altos e inacessíveis nas estruturas arquitetônicas, como por exemplo, alvos em estrutura de edificação situados em torres de igrejas e para a realização de uma estrutura geodésica através do método de nivelamento trigonométrico. As estruturas geodésicas altimétricas, implantadas e determinadas pelo método do nivelamento geométrico, materializam, neste trabalho, pontos para o estabelecimento de padrões de referência altimétrica e para a determinação altimétrica de alvos altos e inacessíveis. As estruturas geodésicas foram implantadas e determinadas, no Sítio Histórico de Olinda, empregando-se nível digital de alta precisão e mira de ínvar com código de barras. Este trabalho tem como objetivo definir padrões de referência altimétrica utilizando o método de nivelamento geométrico, resultando na implantação e análise da qualidade de estruturas geodésicas altimétricas

Deliberating Animal Values: a Pragmatic-Pluralistic Approach to Animal Ethics.

Debates in animal ethics are largely characterized by ethical monism, the search for a single, timeless, and essential trait in which the moral standing of animals can be grounded. In this paper, we argue that a monistic approach towards animal ethics hampers and oversimplifies the moral debate. The value pluralism present in our contemporary societies requires a more open and flexible approach to moral inquiry. This paper advocates the turn to a pragmatic, pluralistic approach to animal ethics. It contributes to the development of such an approach in two ways. It offers a pragmatist critique of ethical monism in animal ethics and presents the results of a qualitative study into the value diversity present in the different ways of thinking about animals in the Netherlands. Carefully arranged group discussions resulted in the reconstruction of four distinctive moral value frameworks that may serve as instruments in the future process of moral inquiry and deliberation in the reflection on animal use. © 2010 The Author(s)

Learning from parents: A qualitative interview study on how parents experience their journey through the Dutch child protection system

The quality of parents' experiences with the child protection system (CPS) is related to the outcomes of their family's process in the system. The importance of collaboration with parents in child protection is underpinned by human and children's rights conventions addressing the right for family life and parents being first responsible in fulfilling children's rights. We interviewed 20 parents about their experiences with the Dutch CPS. Our thematic analysis shows that a CPS serving the best interests of their children is most important to parents. To realize this, professionals should (1) “not let it happen but do something,” (2) “get a clear picture of the family's situation,” and (3) “take parents seriously.” Parents emphasize that a system providing sufficient “money, time, and knowledge” is needed to facilitate professionals. Their experiences seem to influence their trust in the system and their attitude towards it. This study shows new insights in parents' experiences, such as their advice to professionals to determine the truth and to be decisive. This deepened knowledge about parents' experiences is essential for evaluating and improving the CPS

Displacement response of a concrete arch dam to seasonal temperature fluctuations and reservoir level rise during the first filling period: evidence from geodetic data

© 2015 Taylor & Francis. The present study evaluates the dynamic behaviour of the Ermenek Dam, the second highest dam in Turkey, based on conventional geodetic measurements and Finite Element Model (FEM) analyses during its first filling period. In total, eight periods of measured deformation are considered from the end of construction until the reservoir reached its full capacity. The displacement response of the dam to the reservoir level and to seasonal temperature variations is examined in detail. Time series of apparent total displacements at the middle of the crest of the dam exhibits periodicity and linear trends. Correlation analysis revealed that periodic and linear displacement responses of the dam are related to variations of seasonal temperature and linearly increased reservoir level, respectively, indicating a relation between temperature, water load and dam deformation. It is also concluded that measured deformations based on geodetic data show good agreement with the predicted deformation obtained by the FEM analysis
