On the different growth conditions affecting silver antimicrobial efficacy on Listeria monocytogenes and Salmonella enterica.
2012
Abstract Silver is known to inhibit microorganisms and therefore it is an ideal candidate for its incorporation in a wide variety of materials for food applications. However, there is still a need for understanding how silver prolonged exposure to bacterial contamination affects the bioavailability of the active silver species. In the present study, growth curves of Listeria monocytogenes and Salmonella enterica were performed for 3–5 days in Tryptic Soy Broth (TSB) and M9 minimal medium (M9) in the presence of silver ions and silver solutions previously in contact with the growth media. The cultivability of the bacteria under these conditions was correlated with the viability of the bacter…
Advanced Statistical Tools for Six Sigma and other Industrial Applications
Six Sigma is a methodological approach and philosophy for quality improvement in operations management; its main objectives are identifying and removing the causes of defects, and minimizing variability in manufacturing and business processes. To do so, Six Sigma combines managerial and statistical tools, with the creation of a dedicated organizational structure. In this doctoral thesis and the three years of study and research, we have had the purpose to advance the potential applications of the methodology and its tools; with a specific attention on issues and challenges that typically prevent the realization of the expected financial and operational gains that a company pursue in applyin…

Business intelligence requirements in small sized enterprises
2016
Pienet ja keskisuuret yritykset keräävät nykyisin suuren määrän tietoa ja ovat kiinnostuneet Business Intelligencestä (BI), liiketoimintatiedon hallinnasta, pärjätäkseen kilpailussa liiketoimintaympäristössä. PK-yritykset ovat merkittäviä paikallisessa, kansallisessa ja jopa globaalissa mittakaavassa, sillä ne muodostavat ison osan taloudesta. Siitä huolimatta on tutkittu hyvin vähän sitä, minkälaisia vaatimuksia ja tarpeita näillä yrityksillä on BI:tä kohtaan. Tämän Pro gradu -tutkimuksen tavoitteena on selvittää näitä vaatimuksia kvalitatiivisessa tutkimuksessa teema- ja puolistrukturoidulla haastatteluilla. Yhdistävä tekijä BI-termistössä ja näkökulmissa on, se että kaikissa määrityksiss…
Environmental Management Systems (Ems) - Control Instrument of the Impact of the Organization Activities on the Environment
2015
Abstract Due to the ability to create and use technology, the human being has found various ways to transform the resources of the Earth in all sorts of new materials, equipment and energy sources. At least since the last industrial revolution until now, each generation has added more technology to the received legacy, but at the same time, left the planet in a far more degraded state than the inherited condition. Within these changes, small and medium enterprises (SME) in their capacity as pillars of the economic development of a nation, have been compelled to change their previous strategies. Implementing an Environmental Management Systems (EMS) can be seen as the only way to connect the…
Les déterminants de la complexité des systèmes d’information comptables des dirigeants de PME : contingences culturelles et endogénéité
2018
Le premier objectif est d’étudier le lien entre les dimensions de la culture nationale et la complexité des systèmes d’information comptables (SIC) des dirigeants de PME. Le second est de contribuer au débat sur la présence potentielle de biais d’endogénéité dans les précédentes études réalisées sur le thème. Une régression multiple et un test d’Hausman ont été mobilisés en utilisant les réponses de 276 dirigeants de PME françaises, tunisiennes et syriennes. Les quatre dimensions de la culture proposées par Hofstede sont des déterminants significatifs de la complexité des SIC. Le test d’Hausman révèle que l’existence d’endogénéité est peu plausible.
Do social enterprises walk the talk? Assessing microfinance performances with mission statements
2019
We study mission drift in social enterprises by examining whether these organizations stick to the actual mission enshrined in their mission statements. We use data from microfinance organizations (MFOs), a homogeneous group of social enterprises which have been scrutinized—and sometimes criticized—for mission drift. We focus on three publicly recognized and non-mutually-exclusive microfinance social missions identified by previous studies: poverty alleviation, women's empowerment, and rural financial inclusion. Based on hand-collected data from 199 MFOs worldwide, our results suggest strong coherence between social missions and actual practices. Hence, we argue that, with respect to MFOs' …
Lyties dimensija socialiniame versle: Lietuvos socialinių verslininkių patirtys
2017
Straipsnyje nagrinėjama, kaip moterys – socialinės verslininkės – suvokia socialinį verslą ir lyties dedamąją tokiame versle. Interviu (n=18) su socialinių verslų Lietuvoje atstovėmis analizė parodė, kad socialinio verslo misija yra arba labai pragmatiška (organizacijų, turinčių socialinės įmonės juridinį statusą), atsiejama nuo socialinio poveikio, kurį tokie verslai paprastai kuria, arba gana neapibrėžta, tačiau akcentuojanti gėrio kūrimą. Tačiau į lyties dedamąją socialiniuose versluose žvelgiama stereotipiškai, t. y. lyties poveikis arba ignoruojamas, arba interpretuojamas stereotipiškai skirstant į tradiciškai laikomas vyriškomis ir moteriškomis veiklos sritis. This paper explores how …
Volunteer satisfaction in sports clubs: A multilevel analysis in 10 European countries
2020
Regular voluntary engagement is a basic resource for sports clubs that may also promote social cohesion and active citizenship. The satisfaction of volunteers is an imperative factor in this engagement, and the purpose of this article is to explore individual and organizational determinants of volunteer satisfaction in sports clubs. Theoretically, our study builds on the actor-theory concepts where volunteer satisfaction depends on subjective evaluations of expectations and experiences in a sports club (‘logic of situation’), so that positive evaluations lead to higher satisfaction and, hopefully, retention of volunteers. This research uses a sample of 8131 volunteers from 642 sports clubs…
Efficient DNA Packaging of Bacteriophage PRD1 Requires the Unique Vertex Protein P6
2007
ABSTRACT The assembly of bacteriophage PRD1 proceeds via formation of empty procapsids containing an internal lipid membrane, into which the linear double-stranded DNA genome is subsequently packaged. The packaging ATPase P9 and other putative packaging proteins have been shown to be located at a unique vertex of the PRD1 capsid. Here, we describe the isolation and characterization of a suppressor-sensitive PRD1 mutant deficient in the unique vertex protein P6. Protein P6 was found to be an essential part of the PRD1 packaging machinery; its absence leads to greatly reduced packaging efficiency. Lack of P6 was not found to affect particle assembly, because in the P6-deficient mutant infecti…
