User evaluation of learning resource programs in Virginia community collegesHuber, C. Edward 22 June 2010 (has links)
The purpose of this study was to determine the relationship between qualitative evaluation of community college learning resource programs, as measured by a questionnaire distributed to selected faculty and students at eighteen single-campus Virginia community colleges, and quantitative measures frequently used as comparative indicators of program quality. The questionnaire, in two almost identical versions, one for students and one for faculty, was developed from Evaluative Criteria (4th edition, 1969), published by the National Study of Secondary School Evaluation, and consisted of six groups of five questions, each group related to a single quantitative measure, plus one additional overall evaluation question. / Ed.

Hur hamnade vi här? : En kvantitativ innehållsanalys av svenska webbtidningar om hamnkonflikten 2019 / How did we end up here? : A quantitative content analysis of Swedish web magazines on the harbour conflict 2019.Andreasson, Simon, Olsson, Mattias January 2019 (has links)
The purpose of this essay was to examine how eight Swedish newspapers reported on a trade union conflict between dock workers and a employer organisation in the winter of 2019. Further it will examine how the conflict is portrayed in the newspaper and if both of the organisations gets their voices heard in the newspapers. We will also examine what context the conflict mention within. We analyzed eight Swedish newspapers that wrote about the conflict, at the time 7 January - 14 Mars 2019, with help of a quantitative content analysis. The result of this study showed us that the newspapers in Sweden in generally used Primary Definers to get their information so they could write articles about this conflict. It also showed us that the two parties in this conflict, the trade union and the employer, get the chance to speak in the newspaper almost as much as each other. Other findings were made and one of those was that two of Sweden’s largest newspaper barely wrote about this conflict. But when they were writing about this conflict they wrote that this conflict has a big impact on the Swedish economy.

Quantitative Modelling Methods for the Incorporation of Uncertainty into Construction Project EstimatesAdams, Russell John 12 1900 (has links)
Thesis (MEng (Civil Engineering))--University of Stellenbosch, 2006. / Most construction projects do not complete exactly as scheduled or exactly as priced.
During the implementation of a project there is almost certainly some deviation from the
original estimate. The implementation of a majority of projects has actually been shown
to cost more and take longer than originally estimated. However, the duration and cost
performance of a project’s implementation is measured against the initial estimate
produced. Thus if a project is considered to have completed late or over budget then
essentially the duration or cost estimated was insufficient.
Due to the fact that estimates are produced in a present day environment for inherently
unique projects that occur in uncertain future environments, the estimates produced will
need to incorporate uncertainty to increase their likelihood of achievability.
This study aims to derive methods to incorporate future uncertainty into project
estimates. This uncertainty is incorporated, analysed and manipulated through the use
of Probabilistic models and First Order Second Moment Reliability methods. The derived
methods provide project management professionals with tools that enable them to
design estimates that incorporate future uncertainty and are reliable to a specified
degree. Further methods are then derived to probabilistically assess the commercial
feasibility of a project in an uncertain future environment.
These derived methods then provide project managers and decision makers with more
reliable procedures and information which in turn should assist them in making correct,
project orientated decisions and ultimately increase profit reliability and client
satisfaction.

Analyse de l'effet d'un adjuvant biosourcé pour élaborer des matériaux cimentaires plus éco-respectueux / Study of environmental friendly concrete : use of bacterial products to improve their durabilityHe, Huan 17 July 2015 (has links)
Cette thèse s’inscrit dans le cadre du projet SEPOLBE qui a pour ambition d’élaborer des adjuvants respectueux de l’environnement qui doivent se substituer à des produits soumis à autorisation REACH. Elle a pour but de mettre en évidence les propriétés de mortiers enrichis d’un adjuvant fabriqué à partir de produits extracellulaires issus de bactéries selon un protocole original. Ce travail consiste en l’étude des caractéristiques de mortiers bioadjuvantés dans le but de développer l’usage de bétons plus éco‐respectueux en améliorant leurs compositions chimiques et leur durabilité. L’action du produit biologique utilisé a été évaluée aussi bien sur sa capacité à modifier le réseau poreux des mortiers et pâtes cimentaires que sur ses effets sur la prise du ciment, la rhéologie à l’état frais et les caractéristiques mécaniques à l’état durci des mortiers permettant ainsi de qualifier ce produit comme bioadjuvant. Il a présenté un effet notable sur l’ouvrabilité de mortiers (de CEM I ou CEM V) avec une action plastifiante. De plus, quel que soit le temps de cure, un optimum de concentration en bioadjuvant de 1,5% a été déterminé pour obtenir des résistances mécaniques dumême ordre de grandeur que les échantillons non adjuvantés, et supérieures au minimum requis par la norme EN 196‐1. Le bioadjuvant n’influence pas la porosité totale accessible à l’eau des mortiers et des pâtes de ciment, toutefois, pour ces dernières, les mesures par porosimétrie par injection de mercure ont révélé l’existence d’un seuil (entre 0,5 et 0,75% de bioadjuvant) à partir duquel la structure poreuse des pâtes cimentaires est modifiée. Les effets de modification de surface de pâtes cimentaires – le liant du béton pouvant constituer un maillon faible en ce qui concerne les problèmes de durabilité de celui‐ci – ont été analysés. Pour des temps de cure élevés, la rugosité des surfaces des pâtes cimentaires diminue en présence du bioadjuvant. Ce travail a permis de lever des verrous techniques concernant l’emploi d’un produit biosourcé en tant qu’adjuvant, ainsi que d’apporter une contribution à la connaissance des interactions entre les micro‐organismes et les matériaux cimentaires. En effet, une approche originale, grâce à la PCR – technique peu utilisée avec les matériaux cimentaires – a permis de mettre en évidence qu’il y avait des bactéries au coeur du béton ayant une capacité à se développer dans des conditions de cures normalisés pour des temps de cure supérieurs à 120 jours. Le bioadjuvant est susceptible de modifier le développement bactérien et présente ainsi la possibilité de conférer aux bétons des capacités de résistances aux agressions environnementales plus importantes lui permettant d’être plus éco‐respectueux, aussi bien par sa composition que par sa meilleure durabilité. / This work is a part of the SEPOLBE project, which aims to develop eco‐friendly admixtures. The active principle of this admixture is made of extra‐cellular substances, secreted by microorganisms into their surroundings. It contributes to the effort in sustainable development that consists to limit the impact of buildings on environment and human health, with a guarantee of better quality concerning esthetical, durability and resistance criteria, according to the REACH regulation. The action of thisorganic product was evaluated on its setting time effects on cement as well as the mechanical behavior to the hardened state. The bioadmixture presents a significant effect on the workability of mortar (CEM I or CEM V) with a plasticizing action. Whatever the curing time, the compressive strength values of samples containing 1.5% of bioadmixture remain higher than the minimum data of standard strength according to the EN 196‐1 standard. The porosimetry by intrusion with mercury carried out with cement pastes showed the existence of a threshold (in the range 0.5‐0.75% of bioadmixture) from which the porous structure of cement pastes changes, while no modification were observed with the measurement of porosity accessible to water. For higher curing times, thesurface roughness of cement pastes, more heterogeneous, decreases with the presence of the bioadmixture. This work allowed to better control the use of a bio‐product assimilated as an admixture, as well as to contribute to the knowledge of the interactions between microorganisms and cementitious materials. An original approach, using the PCR ‐ not routinely used technique forthat purpose with cementitious materials ‐ helped to highlight that bacteria were present inside the mortar samples with a capacity to grow to higher curing time. The studied bioadmixture allows giving to the concrete the ability to resist against environmental stresses while being eco‐friendly, concerning both its chemical composition and its durability.

Hög tid: att undersöka kvällspressens cannabisrapportering : En kvantitativ och kvalitativ studie av medierapporteringen om cannabis sedan 2010 i Aftonbladet och Expressen / High time: a study of cannabis coverage in the evening press : A quantitative and qualitative study of cannabis media moverage since 2010 in Aftonbladet and ExpressenNeemé, Kevin, Zetterquist, Viktor January 2024 (has links)
This study delves into the media coverage of cannabis by analyzing articles from Aftonbladet and Expressen between 2010 and 2024. Through a combination of quantitative and qualitative methods, the study examines the tone, content, and trends in reporting on cannabis through these years. A total of 904 articles were analyzed, with a focus on identifying patterns, trends, and shifts in the portrayal of cannabis in the two newspapers. The quantitative content analysis involves coding and categorizing a large sample of articles to uncover key themes and frequencies of coverage. Additionally, a qualitative discourse analysis is conducted on a subset of texts to deepen the understanding of how cannabis is framed and represented in the media. The methodological rigor includes inter-coderreliability checks and statistical evaluations to ensure consistency and validity in the analysis process. The findings reveal a predominance of negative articles, with a particular focus on domestic issues in Sweden such as increasing gang violence. The study also highlights the influence of media discourse in shaping perceptions of cannabis, portraying it both as an illegal commodity associated with violence and as a symbol of deviance. By scrutinizing the language and narratives used in media representations, this research sheds light on the construction of cannabis in Swedish newspapers and the potential impact on public attitudes and policies.
