LORAN-C prediction problems

Control of time and frequency at remote stations and the maintenance of a constant time scale for LORAN-C chains are problems of practical importance. The stability of stations monitoring a LORAN-C chain is analyzed, in particular, those stations monitoring the Northwest Pacific chain. Individual determinations of the quantity, U.S. Naval Observatory Master lock are compared with an averaged value and monitored data

Euclidean decompositions of hyperbolic manifolds and their duals

Epstein and Penner constructed in [EP88] the Euclidean decomposition of a non-compact hyperbolic n-manifold of finite volume for a choice of cusps, n >= 2. The manifold is cut along geodesic hyperplanes into hyperbolic ideal convex polyhedra. The intersection of the cusps with the Euclidean decomposition determined by them turns out to be rather simple as stated in Theorem 2.2. A dual decomposition resulting from the expansion of the cusps was already mentioned in [EP88]. These two dual hyperbolic decompositions of the manifold induce two dual decompositions in the Euclidean structure of the cusp sections. This observation leads in Theorems 5.1 and 5.2 to easily computable, necessary conditions for an arbitrary ideal polyhedral decomposition of the manifold to be a Euclidean decomposition

Prison Education in Slovakia from the Teacher\u27s Perspective

The present study deals with teaching practices in prison education in Slovakia. Attention is paid to secondary school teachers who, at the same time, teach adult prisoners. The aim of the qualitative research conducted was to find out in what ways, in the view of the teachers approached, prison education and school education differ and how they react to the differences. Another objective was to find out whether the teachers feel competent enough to teach prisoners. It was found out that theabsence of teacher training for prison education and the power of the prison regime strongly affect teaching practice. The teachers adjusted the syllabus, the pace and demands placed on the learners to the limited conditions of the prison regime. The authors believe that the present study could shed more light on teaching practices in prison education and help recognize such areas where specific teacher training is needed

Tree species’ tolerance to water stress, salinity and fire

According to climate change predictions, water availability might change dramatically in Europe and adjacent regions. This change will undoubtedly have an adverse effect on existing tree species and affect their ability to cope with a lack or an excess of water, changes in annual precipitation patterns, soil salinity and fire disturbance. The following chapter will describe tree species and proven-ances used in European forestry practice which are the most suitable to deal with water stress, salinity and fire. Each subchapter starts with a brief description of each of the stress factors and discusses the predictions of the likelihood of their occurrence in the near future according to the climate change scenarios. Tree spe-cies and their genotypes able to cope with particular stress factor, together with indication of their use by forest managers are then introduced in greater detail

The role of closed ecological systems in carbon cycle modelling

Acquiring a mechanistic understanding of the role of the biotic feedbacks on the links between atmospheric CO2 concentrations and temperature is essential for trustworthy climate predictions. Currently, computer based simulations are the only available tool to estimate the global impact of the biotic feedbacks on future atmospheric CO2 and temperatures. Here we propose an alternative and complementary approaches by using materially closed and energetically open analogue/physical models of the carbon cycle. We argue that there is potential in using a materially closed approach to improve our understanding of the magnitude and sign of many biotic feedbacks, and that recent technological advance make this feasible. We also suggest how such systems could be designed and discuss the advantages and limitations of establishing physical models of the global carbon cycle

Context Based Visual Content Verification

In this paper the intermediary visual content verification method based on multi-level co-occurrences is studied. The co-occurrence statistics are in general used to determine relational properties between objects based on information collected from data. As such these measures are heavily subject to relative number of occurrences and give only limited amount of accuracy when predicting objects in real world. In order to improve the accuracy of this method in the verification task, we include the context information such as location, type of environment etc. In order to train our model we provide new annotated dataset the Advanced Attribute VOC (AAVOC) that contains additional properties of the image. We show that the usage of context greatly improve the accuracy of verification with up to 16% improvement.Comment: 6 pages, 6 Figures, Published in Proceedings of the Information and Digital Technology Conference, 201

Let’s talk about sex: female therapists’ experience of working with male clients who are sexually attracted to them

Sexual attraction in psychotherapy is an under researched area of psychotherapeutic practice. Literature suggests that the direction of the work with sexual attraction is determined by the therapist’s emotional reaction to it which can either halt or spur its exploration with the client and occasionally cause serious ethical misconduct such as sexual acting out and premature therapeutic termination. Given the suggestion that our socio-cultural context is particularly prohibitive of the exploration of the male client’s erotic feelings towards his female therapist, this study focused on female therapists, exploring the nature of their experience working with male clients who are sexually attracted to them and the extent to which they used the experience in their work. The study used Hollway and Jefferson’s (2008) hybrid method ‘Free association narrative interview’. This involved multiple unstructured interviews with five female participants. Follow up interviews provided opportunities for building trust, consideration of non-conscious communication and permitted collaborative meaning-making with participants as co-researchers, considered particularly important given the ‘taboo’ status of the topic. Each participant’s data was initially analysed on its own merit after which data was compared across participants. The results of the study included participants’ emphasis on the uniqueness of working with each different client, the importance of confidentiality, trust and supervision in the work and the link between issues of sexual attraction and our identity. Participants’ experience differed depending on whether they felt reciprocally towards their clients or not. On occasions when therapists were not attracted towards their clients, they expressed a sense of vulnerability, discomfort with power inequality and a sense of being at fault. Conversely, when therapists felt sexually attracted to their clients, they experienced a sense of the splitting of the roles of being a woman and a therapist, as well as the experience of love and mutuality in relation to clients. In terms of the therapists’ use of the experience in their work, the ability to do so was reported within both categories of responses, albeit it seemed that this was easier done in the context of a therapeutic relationship which was described as ‘mutual and loving’. The implications of these results are manifold. In practical terms, my research suggests a need for therapists to consider the safety of the location at which they work. In relation to therapy training, the findings suggest that working with sexual dynamics is not something which can be learnt and mastered but instead needs to be explored reflectively and reflexively. From the clinical point of view, this research suggests that sexual dynamics can be experienced as merging the gap between ‘personal’ and ‘professional’ parts of therapists’ identity because of which the role of personal therapy and clinical supervision are highlighted as particularly important. Finally, my study considered the impact of power inequality on the therapists’ sense of authority from the clinical perspective as well as the context of wider societal dynamics and offered links with previously published research, suggesting future areas for research and clinical practice

Effect of soil waterlogging on below-ground biomass allometric relations in Norway spruce

An increasing importance is assigned to the estimation and verification of carbon stocks in forests. Forestry practice has several long-established and reliable methods for the assessment of aboveground biomass; however we still miss accurate predictors of belowground biomass. A major windthrow event exposing the coarse root systems of Norway spruce trees allowed us to assess the effects of contrasting soil stone and water content on belowground allocation. Increasing stone content decreases root/shoot ratio, while soil waterlogging leads to an increase in this ratio. We constructed allometric relationships for belowground biomass prediction and were able to show that only soil waterlogging significantly impacts model parameters. We showed that diameter at breast height is a reliable predictor of belowground biomass and, once site-specific parameters have been developed, it is possible to accurately estimate belowground biomass in Norway spruce
