Do Cultures Really Matter? : A Case Study of Human Resource Management StrategiesPAN, Shumin January 2009 (has links)
<p>The purpose of this research study is to explore the relationship between cultures and Human Resource Management Strategies in Swedish Multinational Corporations. In order to achieve this purpose, a multiple-methods research design is adopted. The study consists of two steps. The first step is a pilot study which aims to give a general picture and the direction for the further case study. A case study is the second step; here, three companies are studied by conducting interviews: ArtsNordica, TeliaSonera and Company A, with the intention of highlighting the important issues of cultures and HRM strategies.</p>

Évaluation des mélanges multi-espèces de cultures de couverture en grandes cultures biologiquesLavergne, Stéphanie 10 February 2024 (has links)
La gestion de l’azote (N) est un défi pour les producteurs de maïs-grain (Zea mays L.) biologique qui comptent sur les cultures de couverture (CC) pour combler les besoins en N de cette culture. L’objectif de cette étude était de déterminer l’effet de mélanges de CC semés en dérobée sur l’approvisionnement en N du maïs-grain. Une expérience de deux ans a été répétée sur trois années sites. Le dispositif expérimental était un plan factoriel en tiroir avec quatre blocs, où les CC étaient en parcelles principales : un témoin enherbé sans CC, une CC de pois (Pisum sativum L.) et des mélanges de 2, de 6 et de 12 espèces. La fertilisation organique du maïs-grain était en parcelle secondaire (0 ou 120 kg N ha-1 ). Aux trois années-sites, la proportion du pois fourrager variait entre 45 et 93 % de la biomasse aérienne des mélanges. La CC de pois a produit la biomasse aérienne la plus élevée (2,636 kg ha-1 ), mais la biomasse racinaire la plus faible (693 kg ha-1 ) en comparaison avec les mélanges. Le contenu en N de la biomasse aérienne totale variait entre 8 et 140 kg N ha-1 , alors que le contenu en N de la biomasse racinaire était en moyenne de 13 kg N ha-1 . À l’implantation des CC, la biomasse des plantes adventices était inversement corrélée à la biomasse aérienne des CC. Le rendement le plus élevé de maïs-grain a été observé dans la CC de pois et les mélanges de 2 et de 12 espèces, tandis que le rendement le plus faible, dans le témoin enherbé et le mélange de 6 espèces. Finalement, la fertilisation organique a permis d'augmenter le rendement du maïs-grain de 10 % en moyenne. D’autres pratiques innovantes de gestion des CC sont nécessaires pour rendre le système de culture du maïs-grain biologique plus productif. / Grain corn (Zea mays L.) is a high nitrogen (N) demanding crop, and synchronizing N supply with crop N needs is particularly challenging for organic producers. Therefore, they rely heavily on legume cover crops (CC) for N input. The overall goal of the research project was to assess the effect of fall-seeded cover crop mixtures on nitrogen supply to corn. A two-year field experiment was repeated at Laval University experimental farm (2017-2018; 2018-2019) and on an organic commercial farm (2017-2018). The experimental design was a split-plot with four blocks, in which CC treatment (Year 1) was the main plot factor: a weedy control without CC, a pure stand of field pea (Pisum sativum L.), and mixtures of 2, 6 and 12 species. The corn organic fertilization (Year 2) was the subplot factor (0 or 120 kg N ha-1 ). Among all site-years, the proportion of field pea in the total aboveground biomass ranged from 45 to 93%, within all mixtures. The highest aboveground plant biomass (2,636 kg ha-1 ) and the lowest belowground plant biomass (693 kg ha-1 ) were both observed in the pure stand of field pea. In the fall, weed biomass was inversely correlated with cover crop aboveground biomass. Nitrogen content in the aboveground plant biomass ranged from 8 to 140 kg N ha-1 , whereas N content of the belowground plant biomass averaged 13 kg N ha-1 . The highest corn yield was observed in the pure stand of field pea, the 2-species, and the 12-species mixtures, while the lowest yield was observed in the weedy control and the 6-species mixture. Moreover, organic fertilization only increased corn yield by 10% for all CC treatments and site-years. Additional innovative CC management practices are needed to make organic CC-based corn cropping systems more productive.
