Full text linkMagistritöö
Ettevõtluse ja ökonoomika õppekavalEttevõtte tähtsaimaks ressursiks on tema töötajad ning nende heaolu. Lisaks keemilistele,
bioloogilistele, füüsikalistele ja füsioloogilistele ohuteguritele esinevad töökeskkonnas ka
psühhosotsiaalsed ohutegurid, millele tähelepanu pööramata võib tekkida töötajal
tööstress. Ohutegurite hindamiseks ettevõttes tuleb teostada riskianalüüs, mida uuritavas
ettevõttes ei olnud veel tehtud.
Töö eesmärk on välja selgitada kas ja millised psühhosotsiaalsed ohutegurid esinevad
ettevõttes Sievert Eesti AS ning uurimistulemustest tulenevalt teha ettepanekud juhatusele
nende tegurite ennetamiseks ja maandamiseks. Uurimismeetodina kasutati kirjalikku
ankeetküsimustikku ja uurimisvahendina tööstressi kaardistaja küsimustikku, milles
hinnatakse kuut peamist psühhosotsiaalset faktorit. Nendeks on: töö poolt esitatud nõuded,
kontroll (sõnaõigus), toetus (kolleegide ja juhipoolne), suhted tööl, roll ja muutuste
juhtimine. Küsitluse tulemuste analüüsimisel selgitati välja ettevõttes esinevad
ohutegurid, mille põhjal teostati riskianalüüs.
Küsitluse tulemustest selgus, et kõige problemaatilisemateks psühhosotsiaalseteks
ohuteguriteks ettevõttes on töötajate omavahelised suhted, tööle esitatavad nõudmised
ning juhi ja kolleegide poolse toetuse puudumine. Tuginedes küsitluse tulemustele, teeb
töö autor ettepanekud juhatusele edaspidiseks tegevuseks ettevõttes.The most important resource of a company is its employees and their well-being. In
addition to chemical, biological, physical and physiological risks in work environment,
there is also psychosocial risks which if ignored, can lead to work related stress. In order
to assess risk factors, a risk analysis must be performed, which had not yet been done in
the company under this study.
The aim of this study is to find out if and which psychosocial risks occur in Sievert Eesti
AS and based on the research results, to make proposals to management for prevention
and mitigate these factors. As a research method, questionnaire was used and a work stress
mapping questionnaire was used as a research tool, in which six main psychosocial factors
were assessed. There are: job demands, control, support (colleagused and manager),
relationships at work, role and changes. Based on reasearch results the factors were
identified and based on them risk analysis was performed.
The results showed that the most problematic psychosocial risk factors in the company are
the relationship between employees, the job demands and lack of support from the
manager and colleagues. Based on the results on the survey, author makes suggestions to
the management for future activities in the company
High-resolution spectroscopy of gaseous 83m Kr conversion electrons with the KATRIN experiment
No full text© 2020 The Author(s). Published by IOP Publishing Ltd. In this work, we present the first spectroscopic measurements of conversion electrons originating from the decay of metastable gaseous 83mKr with the Karlsruhe Tritium Neutrino (KATRIN) experiment. The obtained results represent one of the major commissioning milestones for the subsequent direct neutrino mass measurement with KATRIN. The successful campaign demonstrates the functionalities of the KATRIN beamline. Precise measurement of the narrow K-32, L3-32, and N2,3-32 conversion electron lines allowed to verify the eV-scale energy resolution of the KATRIN main spectrometer necessary for competitive measurement of the absolute neutrino mass scale

KATRIN: Status and Prospects for the Neutrino Mass and Beyond
Full text linkThe Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to measure a
high-precision integral spectrum of the endpoint region of T2 beta decay, with
the primary goal of probing the absolute mass scale of the neutrino. After a
first tritium commissioning campaign in 2018, the experiment has been regularly
running since 2019, and in its first two measurement campaigns has already
achieved a sub-eV sensitivity. After 1000 days of data-taking, KATRIN's design
sensitivity is 0.2 eV at the 90% confidence level. In this white paper we
describe the current status of KATRIN; explore prospects for measuring the
neutrino mass and other physics observables, including sterile neutrinos and
other beyond-Standard-Model hypotheses; and discuss research-and-development
projects that may further improve the KATRIN sensitivity.Comment: Contribution to Snowmass 2021. 70 pages excluding references; 35

Exosome Secretion Ameliorates Lysosomal Storage of Cholesterol in Niemann-Pick Type C Disease
No full textNiemann-Pick type C1 disease is an autosomal-recessive lysosomal storage disorder. Loss of function of the npc1 gene leads to abnormal accumulation of free cholesterol and sphingolipids within the late endosomal and lysosomal compartments resulting in progressive neurodegeneration and dysmyelination. Here, we show that oligodendroglial cells secrete cholesterol by exosomes when challenged with cholesterol or U18666A, which induces late endosomal cholesterol accumulation. Up-regulation of exosomal cholesterol release was also observed after siRNA-mediated knockdown of NPC1 and in fibroblasts derived from NPC1 patients and could be reversed by expression of wild-type NPC1. We provide evidence that exosomal cholesterol secretion depends on the presence of flotillin. Our findings indicate that exosomal release of cholesterol may serve as a cellular mechanism to partially bypass the traffic block that results in the toxic lysosomal cholesterol accumulation in Niemann-Pick type C1 disease. Furthermore, we suggest that secretion of cholesterol by exosomes contributes to maintain cellular cholesterol homeostasis
The haunted public sphere: women and the power of emotion in the works of Alexander Kluge and the films of the Berlin School
No full textMy dissertation sheds light on the German filmmaker and author Alexander Kluge and his ideas on filmmaking as they evolved out of his conception of the public versus the private spheres since the early 1960s. It was Kluge’s contention that personal experiences of war and violence could not be expressed publicly in the postwar Federal Republic, causing a rift between the two realms and a haunting presence of trauma within individuals and society as a whole. What Kluge, in cooperation with Oskar Negt, called “alternative public sphere” in Public Sphere and Experience (1972) and History and Obstinacy (1981) is closely linked to Woman and so-called “proletarian” forces countering instrumental reason and the bourgeois cultural matrix. Analyzing four crucial films from Kluge’s creative work, I outline the increasingly allegorical role of his concept of “female mode of production,” which constitutes Kluge’s aesthetics and thematic focus. How the ideas of “alternative public sphere” and “female mode of production” are linked to the cinema and Kluge’s theory of film is the focus of another chapter that scrutinizes Kluge’s recent literary compilation Cinema Stories (2007). Finally, I read a selection of contemporary German films considered the new filmic avant-garde through the lens of Kluge’s approach to film, to the “female mode of production,” and to the public sphere. This allows me to compare the ethics, the formal and political attitude of the so-called Berlin School directors to the vanguard movement of Young German Film in the sixties and early seventies. I conclude that the filmic Autoren today deal with a similar problem as Alexander Kluge has done throughout his career, namely the dissociation of personal, lived experience from public representation. They also employ formal and thematic strategies that can be related to the thoughts behind the Oberhausen generation of German filmmakers. While the generation of the leftist student movements sought public recognition of the atrocities committed under National Socialism, the Berlin School directors deal with mediated experience in times of media and finance corporatism as virtual realities threaten to take over the empiric world.Ph.

ecological education and practice-based design
Full text linkDieser Titel ist parallel zur Online-Version in gedruckter Form im Universitätsverlag der TU Berlin unter der ISBN 978-3-7983-2726-9 erschienen.Urbane Landwirtschaft ist ein Thema, dass viele anspricht und dabei ständig neue AnhängerInnen gewinnt. Es scheint ein zutiefst menschliches Bedürfnis zu sein, sich trotz fortschreitender Urbanisierung mit der Herkunft und Erzeugung von Nahrungsmitteln auseinanderzusetzen und sich damit sowohl der Natur als auch einer nachhaltigen Zukunft (wieder) ein Stück anzunähern.
Spiel/Feld Urbane Landwirtschaft eröffnet den Lesenden das kreative Potenzial produktiver Stadtlandschaften durch die Vorstellung eines Projektbeispieles – Spiel/Feld Marzahn -, welches das Fachgebiet Stadt & Ernährung der Technischen Universität Berlin zwischen 2011 und 2014 betreute.
Von am Projekt beteiligten sowie zusätzlich eingeladenen AutorInnen werden besonders solche Fragen genauer beleuchtet, die sich mit den vielfältigen Wechselwirkungen von Urbaner Landwirtschaft und ökologischer Bildung beschäftigen. Ziel ist es zum einen, die Notwendigkeit solcher Verknüpfungen aufzuzeigen und zum anderen darzustellen, wie sie praktisch umsetzbar und erfahrbar sein können.
Das Buch richtet sich an alle, die mehr über Themen der Urbanen Landwirtschaft und produktiven Stadtlandschaft und über mögliche Lehr- und Lernmethoden zu ihrer Verbreitung erfahren bzw. erleben möchten. Von GraswurzelaktivistInnen bis zu StadtplanerInnen, von KleingärtnerInnen bis zu urbanen AgrarunternehmerInnen, vom Schulkind zu Studierenden zu Niemalsauslernenden sind Menschen aller Herkunft und Schichten angesprochen.Urban agriculture is a topic that is currently finding an increasing number of supporters. For good reason: Despite the progression of urbanisation, it seems to be a human desire to understand our food’s origin and its methods of production as a means of getting closer again to nature and a sustainable future.
Playing/Field Urban Agriculture introduces the reader to the creative potential of productive urban landscapes by looking at a case study project – Playing/Field Marzahn – that was supervised by the Department City & Nutrition at the Technical University between 2011 and 2014.
In this book, questions concerning the manifold interdependencies of urban agriculture and ecological education will be discussed by those involved in the project and other invited authors. Our goal is to not only show the necessity of such connections, but also to illustrate how they may be practically implemented and become experienceable.
This book addresses those who would like to explore the topics of urban agriculture and productive urban landscapes, as well as possible teaching and learning methods for their further expansion
Thoughts on the Importance of the Meso Perspective: the “ Plattform Produktives Stadtgrün” / Gedanken zur Bedeutung der Mesoperspektive: „Plattform Produktives Stadtgrün“
No full textInvited to contribute to a book section on Berlin, Katrin Bohn thinks about the importance of a middle ground between the big pressing macro questions of climate change and the micro spaces of individual food system activities. She writes: ‘Judging by the realities of environmental degradation, traditional urban planning has failed. Concerns of experts have not been sufficiently acknowledged. It requires a middle ground—a meso perspective—to better enable conversation between the various urban stakeholders and bring about widely supported and lasting change. How can this be initiated? In a time of social media, the author proposes to look at a recently developed tool for information, communication, networking, and—ultimately—urban planning’.Bohn uses the Plattform Produktives Stadtgrün [Plattform Productive Urban Green], a Berlin-based interactive online tool developed in a collaboration between the local council, local community gardeners and external experts, including Katrin, to illustrate such a meso perspective.The book Urban Open Space + is edited by Carolin Mees and published by Jovis. Subtitled Strategies inbetween architecture and open space planning, the bi-lingual publication (English/German) explores ‘commonly used and designed open spaces [as] anchor points in the city and a possible response to the consequences of urbanization and climate change, as well as to the presence of social and cultural differences’
The influence of employer`s brand on the employee recruitment in the Lasita Maja group
Full text linkMagistritöö
Ökonoomika ja ettevõtluse õppekavaKäesoleva magistritöö eesmärk on välja selgitada, milline on Lasita Maja grupi bränd tööandjana ja kuidas see mõjutab personali värbamist.
Uurimismeetodina kasutas autor kvantitatiivuuringut, koostades ankeetküsimustiku, mida ettevõtte töötajad täitsid paberkandjal ja võrdlusgrupp elektrooniliselt. Lisaks koguti andmeid poolstruktureeritud intervjuu kaudu tootmisjuhiga. Teema aktuaalsus seisneb kvalifitseeritud vaba tööjõu nappuses tööturul ja ettevõtte suurenevas vajaduses kvalifitseeritud personali järele.
Magistritöö teema valik on seotud asjaoluga, et tööandja brändi pole ettevõttes eraldi uuritud ja soov on teada saada peamistest tööandja brändiga seotud põhjustest, mis puudutavad tulemuslikku värbamist ja tööandja brändi
Käesolev magistritöö koosneb erinevatest kirjandusallikatest ja teadusartiklitest. Kirjandusallikatest on kasutatud nii kodumaiseid kui ka välisautorite töid
Käesoleva töö tulemusi saab kasutada ettevõtte siseinfoallikana eelolevate uuringute planeerimisel ja korraldamisel, ettevõtte tulemusliku värbamisprotsessi ja strateegia väljatöötamisel ja oma töötajaskonna soovituste andmisel potentsiaalsetele töötajatele.
Käesoleva magistritöö eesmärgi täitmiseks on autori poolt teostatud kvantitatiivne juhtumiuuring Lasita Maja Eesti grupi kolmest tööandjast: Lasita Maja Production AS, Lasita Maja AS ja Bohlen AS ja võrdlusuuring ettevõttega mitte seotud inimestest.
Autor analüüsis käesoleva uuringu tulemusi demograafiliste näitajate põhiselt, et saada faktipõhist informatsiooni parendusettepanekute tarbeks.
Tähtsamate tulemustema võib välja tuua, et ettevõtte tööandja bränd ei ole väga tuntud, kuid mainet pidasid vastajad pigem heaks. Enimkasutavaks infokanaliks on ettevõtte koduleht, sõbra/tuttava soovitus ja internetiportaalid. Vastajad teavad, mis tooteid ettevõte toodab ja ettevõte on tuntud oma kvaliteetsete toodete poolest. Üle 60% kõikidest vastajatest soovitaks Lasita Maja kui tööandjat kõigile. Peamine põhjus, miks inimesed püsivad tööandja juures on tööaeg, tööga rahulolu ja ettevõtte maine. Ettevõtte brändi mõju värbamisele on pigem positiivne ja soodustab tulemuslikku värbamist.The aim of this Master's thesis is to identify what is the brand of the Lasita Maja group as an employer and how it affects the recruitment of staff.
As a research method, the author used a quantitative study, by drawing up a questionnaire filled out by the employees of the company on paper and by the reference group electronically. In addition, the data was collected through a semi-structured interview with the production manager.
The actuality of the topic lies in the shortage of skilled free labor in the labor market and the company´s growing need for qualified personnel.
The choice of the topic of the Master's thesis is related to the fact that the employer's brand has not been individually investigated in the company and the desire to know the reasons for the main employers' brand related to effective recruitment and the employer's brand.
This Master's thesis consists of various sources of literature and scientific articles. The sources of literature used are both domestic and foreign.
The results of this work can be used as an internal source for the company in planning and organizing future studies, developing a company's effective recruitment process and strategy, and providing its employees with recommendations for potential employees.
For the purpose of this Master's thesis, the author has conducted a quantitative case study and benchmarking of three employers of Lasita Maja Estonian Group: Lasita Maja Production AS, Lasita Maja AS and Bohlen AS.
The author analyzed the results of this study on the basis of demographic indicators in order to obtain factual information for improvement proposals.
The most important results show that the employer's trademark is not very well known, but respondents considered the reputation rather good
The most commonly used information channel is the company's homepage, a friend´s/acquaintance´s tips, and internet portals. Respondents know what products the company produces and the company is known for its high quality products. More than 60% of all respondents would recommend Lasita Maja as an employer for everyone. The main reason why people stay with the employer is working hours, job satisfaction and company's reputation. The brand's impact on recruitment is rather positive and encourages effective recruitment
