Hydrogen plasma induced photoelectron emission from metal surfaces

2018

Low temperature hydrogen plasmas are strong sources of vacuum ultraviolet radiation. The properties of laboratory plasmas can be influenced by surface processes induced by photons with their energies exceeding the surface work function of the wall material. In this work, the plasma induced photoelectron emission has been studied with different ion sources. The emission depends on the mechanical design of the plasma device, plasma heating method and the discharge power (density). Parametric studies include the quantifying of the emission from different metal surfaces, commonly used as plasma facing materials in ion sources, as well as alkali metal covered surfaces. Experimental studies sugges…

Funkcionālā imunitāte par trešajā valstī veiktiem noziegumiem

2016

Bakalaura darbs “Funkcionālā imunitāte par trešajā valstī veiktiem noziegumiem” sniedz ieskatu funkcionālās imunitātes būtībā, kā arī funkcionālās imunitātes piemērošanas subjektu noteikšanā un gadījumos, kad funkcionālā imunitāte kolidē ar citām starptautisko tiesību normām. Darba mērķis ir noskaidrot funkcionālās imunitātes (ratione materiae) tvērumu, personu un darbību loku, uz ko funkcionālā imunitāte ir attiecināma, kā arī izņēmumus no funkcionālās imunitātes piemērošanas. Darba gaitā tiek akcentēti tādi pastāvoši problēm jautājumi, kas izriet no ārvalstu tiesu jurisdikcijas, kā neskaidrība par personu loku, uz ko var attiecināt funkcionālo imunitāti, darbības, kas uzskatāmas par ofici…

La valeur et la vulnérabilité des espaces agricoles du département du Doubs : identification et évaluation multicritère des espaces agricoles

2019

This paper is part of the update of the atlas of the value and vulnerability of agricultural areas in the French territory of Doubs. It is a project initiated by the French “Direction Départementale des Territoires”, carried out in 2012 by the ThéMA laboratory, and whose update began in January 2019. The objective is to create a decision-making tool for spatial planning and development, for sustainable spatial management. This work presents the method for identifying agricultural areas in the Doubs and their evaluation based on a multi-criteria analysis built on four indices: environmental, spacial structure, financial assistance and labelling.

Essays on social capital and space

2014

The idea of specific values and beliefs as, ceteris paribus, the main explanatory of growth differentials, has recently received lot of attention by social scientists. The focus is in particular to specific shared values and beliefs, constituting a social "stock" of good values fostering growth and cooperation, thus the name, social capital. Unfortunately, social capital is an elastic concept. Moreover, to the extent that social interactions type and strength matter, social capital clearly requires attention for the role of space. Thus, this thesis attempts to clarify some of the issues related to social capital and space. In the first chapter we outline the main questions of this thesis, i…

València en la Restauración: reformas y percepciones sociales del espacio urbano (1875-1910)

2021

Esta tesis doctoral trata sobre la relación entre las reformas urbanas que experimentó València entre 1875 y 1910 con las percepciones espaciales de diversos grupos sociales que vivían, trabajaban en ella, la representaban y gobernaban. En concreto, explora cómo influyeron distintas maneras mediáticas y literarias de sentir y representar el espacio y el conflicto social en la ciudad en los proyectos de reforma urbana de València y, en concreto, en su casco histórico. Al igual que otras urbes europeas y españolas, las élites políticas y arquitectónicas de la ciudad del Turia plantearon la construcción de grandes vías e infraestructuras municipales, así como el derribo de barrios céntricos.

Māsu saskarsme ar vardarbību strādājot uzņemšanas nodaļā

2022

Bakalaura darba tēma “Māsu saskarsme ar vardarbību strādājot uzņemšanas nodaļā”. Darba aktualitāti nosaka vardarbīgu gadījumu skaita pieaugums pret māsām darba vidē. Pētījums tika veikts ar mērķi noskaidrot māsu saskarsmi ar vardarbību strādājot uzņemšanas nodaļā. Lai to sasniegtu, tika izvirzīti vairāki uzdevumi – analizēt Kalistas Rojas piemērošanās teoriju; analizēt un apkopot literatūras avotus par vardarbību, vardarbību darba vidē, vardarbību pret māsām; izstrādāt pētījuma instrumentu – anketu māsām, lai noskaidrotu, kāda ir māsu saskarsme ar vardarbību strādājot uzņemšanas nodaļā; veikt pētījumu, apkopojot un analizējot iegūtos datus; apkopot secinājumus. Izvirzītā hipotēze – māsas, k…

Diversity in warning coloration: selective paradox or the norm?

2019

Aposematic theory has historically predicted that predators should select for warning signals to converge on a single form, as a result of frequency-dependent learning. However, widespread variation in warning signals is observed across closely related species, populations and, most problematically for evolutionary biologists, among individuals in the same population. Recent research has yielded an increased awareness of this diversity, challenging the paradigm of signal monomorphy in aposematic animals. Here we provide a comprehensive synthesis of these disparate lines of investigation, identifying within them three broad classes of explanation for variation in aposematic warning signals: …

Características de los vecindarios y la distribución espacial de problemas sociales en la ciudad de Valencia

2018

The aim of this doctoral thesis is to explore the influence of neighborhood-level variables on the spatial and spatio-temporal distribution of different social problems in the city of Valencia. In Study 1, we present data on the development and validation of an observational instrument to assess neighborhood disorder. Results supported a three-factor model (physical disorder, social disorder and physical deterioration), and they showed good reliability and validity evidences. In Study 2, we assess the psychometric properties of a neighborhood disorder scale using Google Street View. Results supported a bifactorial solution with a general factor (general neighborhood disorder) and two specif…

Transformative technologies, spatial changes : essays on mobile phones and the Internet

2009

Sakari Taipale tarkastelee väitöskirjassaan sitä, kuinka matkapuhelimen ja internetin käyttö vaikuttaa sosiaalisten tilojen muodostumiseen.Uudet informaatio- ja kommunikaatioteknologiat ovat monipuolistaneet sosiaalisen vuorovaikutuksen muotoja. Matkapuhelimen ja internetin avulla sosiaalisia tiloja, erilaisia toimijoiden yhteenliittymiä, voidaan luoda tietoverkoissa ilman toisten ihmisten fyysistä läsnäoloa. Tämän seurauksena sosiaalisen tilan kahden keskeisen osatekijän, rajojen ja tarkoituksen, välinen suhde on muuttunut. Rajat näyttävät menettäneen suhteellista merkitystään sosiaalisen tilan koossapysyvyyden kannalta, kun taas tilan tarkoituksen merkitys on vahvistunut.- Verkkoympäristö…
