Designing a System of Time Allowances for the Nurme Production OÜ
No full textAntud uurimistöö kujunes välja ettevõtte Nurme Production OÜ soovist parendada normeerimissüsteemi. Ettevõttes oli normeermisprotsessis kasutusel üks abiajakoefitsient, milletõttu ei võimaldanud see täpsete standardaegade väljatöötamist. Sellest tulenevalt kujunes lõputöö eesmärgiks abiaegade süsteemi väljatöötamine ettevõttele Nurme Production OÜ.
Lõputöö I osas anti ülevaade ettevõttest, ettevõtte toodangust, selle struktuurist ja töökorraldusest.
Lõputöö II osas keskendus autor tööuuringute ettevalmistamisele, läbiviimise kirjeldamisele ja vaatlustulemuste analüüsile. Ettevalmistuste käigus kaardistas autor ettevõttes olevad seadmed ja liigitas need erinevateks uurimisrühmadeks: süstikpiste-, äärelõikusega süstikpiste-, äärestusühendus-, teipimismasinad, pressimisseadmed, pool-automaadid ja kattemasinad.
Autor kogus andmeid tööajakulutuste uuringute ehk päevapildistamiste näol, kus märkis vaatluslehele minuti täpsusega ülesse vaadeldava isiku poolt tehtavad tegevused tööpäeva jooksul ning seejärel arvutas abiaja kestuse, koefitsiendi ja analüüsis tulemusi.
Päevapildistamisi viidi läbi perioodil 9.02.2021 – 30.04.2021, kus vaadeldi 23 tööpäeva jooksul 24 töötajat ja viidi läbi 50 päevavaatlust. Päevavaatluste käigus uuriti 15x süstikpiste-, 7x äärestusühendus-, 10x teipimis-, 8x pressimis-, 6x äärelõikuriga süstikspiste- ja 4x pool-automaatide masinate tööd. Vaatlusperioodi hulka jäi 5 nädala pikkune vahemik, kus koroonaviiruse leviku tõttu ei olnud tootmises võimalik päevavaatlusi läbi viia.
Lõputöö III osas keskendus autor töö järeldustele ja ettepanekutele. Arvutuste ja analüüsi tulemusena selgus keskmine abiaja koefitsiendi tulemus järgnevatele seadmetele: teipimisseadmetele 1,10, süstikpistemasinatele ja pool-automaatidele 1,11 ning pressimis- ja äärestusühendusseadmetele 1,12.
Abiaja koefitsiendi täpsustamine erinevatele seadmetele on üks osa normeerimissüsteemi parendamisest ettevõttes, mistõttu tegi autor ettepaneku edaspidi uurida laialdasemalt eksperimentaal- ja õmblusliinide tööoperatsioonide aegu ning luua ja võtta kasutusele töötajate jõudlustabel. Lisaks tuleb täpsustada pool-automaatide abiajakoefitsienti lisavaatluste näol ja uurida kattemasinate tööpäevajaotust, kuna uuritud perioodil ei olnud vastvad seadmed piisavalt tööga koormatud. Lisaks tegi autor ettepaneku rohkem tähelepanu pöörata taastusaja sihipärasele kasutamisele ja töövõimlemise olulisusele.
Lõputöö valmis koostöös Nurme Production OÜ-ga. Autor tänab Nurme Production OÜ tootmisjuhti ja ühtlasi ka selle lõputöö ühte juhendajatest Kristi Sildet võimaluse eest teostada ja läbi viia uuringuid ning tänab ettevõtte tehnolooge ja töötajaid koostöö eest. Ühtlasi tänab autor põhjaliku juhendamise eest koolipoolset juhendajat Merje Beilmanni.The aim of the thesis was to develop a system of assistance times for Nurme Production OÜ. This thesis resulted from the desire of the company Nurme Production OÜ to improve the standardization system. The company used an equivalent coefficient of assistance time in the standardization process, which did not allow the development of precise standard times.
Part I of the thesis gave an overview of the company, the company's production, its structure and work organization.
In Part II of the thesis, the author focused on the preparation of the research, the description of the conduct and the analysis of the observation results. In the course of the preparations, the author mapped the sewing machinery in the company and classified it into different research groups: single needle lock stitch, single needle lockstitch with edge cutter, overlock, taping machines, pressing machines, semi-automatic machines and flatlock machines.
The author collected data while observing workers use of time which she recorded on the observation sheets and therefore calculated the duration, coefficient and analyzed the results.
Daily observings were taken in the period 9.02.2021 - 30.04.2021, where 24 employees were observed during 23 workdays which resulted in 50 observations altogether. The author of this research observed 15 times single-needle lock stitch, 7 times overlock, 10 times taping, 8 times pressing, 6 times single-needle lock stitch machines with edge cutter and 4 times semi-automatic machines. The observation stage included a 5-week period during which it was not possible to perform daily observations due to the spread of the coronavirus in production.
In Part III, the author focused on the conclusions and suggestions of the thesis. As a result of the calculations and analysis, the average result of the coefficient of the assistance time was found for the following machines: taping machine 1.10, single needle lockstitch and semi-automatic machines 1.11, and pressing and overlock machines 1.12.
The coefficient of the assistance time for different machines is a small part of improving the standardization system, which is why the author proposed to study standard times of experimental and sewing lines in more detail and to create a workers rating factor table. In addition, it is necessary to specify the assistance time coefficient of the semi-automatic machines in the form of additional observations and also to research flatlock machines, as the corresponding machines were not in use during the studied period. In addition, the author suggested paying more attention to the purposeful use of recovery time and the importance of physical exercise.
The thesis was completed in cooperation with Nurme Production OÜ. The author acknowledges Kristi Silde, the production manager of Nurme Production OÜ, for the opportunity to conduct research, and thanks the company's technologists and employees for their cooperation. The author also acknowledges the supervisor of this thesis, Merje Beilmann, for the thorough guidance
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
