Biophysical parameter retrieval with warped Gaussian processes
2015
This paper focuses on biophysical parameter retrieval based on Gaussian Processes (GPs). Very often an arbitrary transformation is applied to the observed variable (e.g. chlorophyll content) to better pose the problem. This standard practice essentially tries to linearize/uniformize the distribution by applying non-linear link functions like the logarithmic, the exponential or the logistic functions. In this paper, we propose to use a GP model that automatically learns the optimal transformation directly from the data. The so-called warped GP regression (WGPR) presented in [1] models output observations as a parametric nonlinear transformation of a GP. The parameters of such prior model are…
The Influence of Cultural Competence on the Interpretations of Territorial Identities in European Capitals of Culture
2014
Abstract The EU’s cultural initiative ‘the European Capital of Culture’ (ECOC) includes high identity political aims. It requires the designated cities to introduce and foster local, regional, and European cultural identities. In addition, the cities have used the designation as an opportunity to promote national cultural identity. Audiences of the ECOC events recognize and interpret different kinds of representations of territorial cultural identities from what the cities have to offer in culture. However, the contents of these interpretations vary drastically in the ECOCs. The article discusses whether the competence of interpreting the representations of territorial cultural identities i…
Narkotisko un psihotropo vielu diskurss Holivudas filmās: jauniešu realitātes konstruēšana
2016
Pētījuma problēma Bakalaura darbā „Narkotisko un psihotropo vielu diskurss Holivudas filmās: jauniešu realitātes konstruēšana” ir kā Holivudas filmās attēlotais narkotisko un psihotropo vielu saturs ietekmē jauniešu realitāti. Darba autore vēlas koncentrēties uz to, kā Holivudas filmas ietekmē tās auditorijas realitāti un viedokli, kā arī meklēt izvēlēto filmu saturā attēlotās narkotiskās un psihotropās vielas, lai noteiktu, cik bieži auditorijas ar to sakaras un vai tas ir spējīgs ietekmēt šīs auditorijas. Tas tiks veikts ar kvantitatīvās kontentanalīzes, semiotiskās analīzes un fokusa grupas palīdzību. Darba teorētiskajā daļā tiks aprakstītas teorētiskās izpratnes par to, kas ir populārā …
Exploring Links between Internal and International Migration in Albania: a View from Internal Migrants
2013
Over the last 20years, Albania has experienced sweeping economic and social changes, caused in part by increasing internal and international migration flows. Migration trajectories of Albanians represent a combination of internal, international, and return migration. Whereas scholars have previously focused mainly on international migration, the current research explores the dynamics between internal and international migration. Typically, the internal migration of a family is supported, psychologically and financially, by the international migration of other household members. This paper reports on the influence that social and economic remittances have on the livelihoods of internal migra…
Sequential Monte Carlo Methods in Random Intercept Models for Longitudinal Data
2017
Longitudinal modelling is common in the field of Biostatistical research. In some studies, it becomes mandatory to update posterior distributions based on new data in order to perform inferential process on-line. In such situations, the use of posterior distribution as the prior distribution in the new application of the Bayes’ theorem is sensible. However, the analytic form of the posterior distribution is not always available and we only have an approximated sample of it, thus making the process “not-so-easy”. Equivalent inferences could be obtained through a Bayesian inferential process based on the set that integrates the old and new data. Nevertheless, this is not always a real alterna…
Biophysical parameter estimation with adaptive Gaussian Processes
2009
We evaluate Gaussian Processes (GPs) for the estimation of biophysical parameters from acquired multispectral data. The standard GP formulation is used, and all hyperparameters (kernel parameters and noise variance) are optimized by maximizing the marginal likelihood. This gives rise to a fully-adaptive GP to data characteristics, both in terms of signal and noise properties. The good numerical results in the estimation of oceanic chlorophyll concentration and leaf membrane state confirm GPs as adequate, alternative non-parametric methods for biophysical parameter estimation. GPs are also analyzed by scrutinizing the predictive variance, the estimated noise variance, and the relevance of ea…
The community conserved landscape of the Borana Oromo, Ethiopia
2011
Purpose - This paper seeks to describe an attempt to assess at the local level the progress that has been internationally achieved in recognition of community and indigenous rights, and of indigenous and community conserved areas. An action-research exercise was implemented in Ethiopia with a mobile indigenous people of evaluating customary as well as government-led governance of the environment, with the objective of strengthening the capacity of the Borana-Oromo to conserve their landscape. Design/methodology/approach - This paper is based on collaborative research implemented by the authors in 2002 while SOS Sahel Ethiopia was introducing collaborative forest management, and on a 2007 ac…
Structure and function of the vacuolar Ccc1/VIT1 family of iron transporters and its regulation in fungi
2020
Iron is an essential micronutrient for most living beings since it participates as a redox active cofactor in many biological processes including cellular respiration, lipid biosynthesis, DNA replication and repair, and ribosome biogenesis and recycling. However, when present in excess, iron can participate in Fenton reactions and generate reactive oxygen species that damage cells at the level of proteins, lipids and nucleic acids. Organisms have developed different molecular strategies to protect themselves against the harmful effects of high concentrations of iron. In the case of fungi and plants, detoxification mainly occurs by importing cytosolic iron into the vacuole through the Ccc1/V…
Vecāku audzināšanas stilu saistība ar iekšējo runu un emociju regulāciju pusaudžiem.
2019
Bakalaura darba pētījuma mērķis bija noskaidrot, vai pastāv saistības starp vecāku audzināšanas stilu, iekšējo runu un emociju regulāciju pusaudžiem. Pētījumā piedalījās 53 jaunieši vecumā no 12 līdz 16 gadiem (M=13,98, SD=1,39), no tiem 35 meitenes un 18 zēni. Pētījumā tika izmantota Vecāku autoritātes aptauja (Parental Authority Questionnaire, PAQ; Buri, 1991) un Emociju regulācijas aptauja (Emotion Regulation Questionnaire, ERQ; Gross & John, 2003), kā arī Papildināta iekšējās runas aptauja (Varieties of Inner Speech Questionnaire – Revised, VISQ-R; Alderson-Day, Mitrenga, Wilkinson, McCarthy-Jones, & Fernyhough, 2018), kuru adaptējusi bakalaura darba autore šī pētījuma ietvaros. Pētījum…
Veselības aprūpes sistēma ieslodzījuma iestādēs
2022
Viena no cilvēktiesību daļām ir arī personas tiesības uz veselību, kas pieder ikvienam, neatkarīgi no tā, vai persona atrodas ieslodzījumā vai brīvībā. Respektīvi, cilvēktiesības ir ikvienam, bez diskriminācijas, un tādas cilvēktiesības kā tiesības uz dzīvību un tiesības uz veselību nedrīkst ierobežot, jo šīs tiesības nodrošina cilvēka būtību un eksistenci pasaulē. Personas, kas izdarījušas noziedzīgus nodarījumus un notiesātas ar brīvības atņemšanu, iekļūst ieslodzījuma vietās, kur tām tiek ierobežotas tādas cilvēktiesības kā tiesības uz brīvību, tomēr tas nenozīmē, ka šīm personām nav tiesības uz veselības aprūpi, ko garantē gan starptautiskie normatīvie akti, gan nacionālie normatīvie ak…
