Chefsintroduktioner : En satsning som lönar sig
No full textChefsintroduktioner har visat sig, i forskning, vara av största vikt för att en chef på rätt sätt ska komma in i sitt arbete, utföra bästa möjliga jobb och stanna hos organisationen så länge som möjligt. Forskning lyfter fram tre delar som viktiga för att underlätta för inträdet i organisationen. De delar som bör ingå i en chefsintroduktion är att skapa en systemförståelse, bli insocialiserad i kulturen på arbetsplatsen och nätverksskapande. Syftet med min studie är att undersöka om dessa delar finns i chefsintroduktioner i praktiken. Min studie är fokuserad kring en större organisation med cirka 10 000 anställda där jag har intervjuat 7 nyanställda verksamhetschefer om deras chefsintroduktion. Under intervjuerna framkom att systemförståelsen och insocialiseringen ingår i chefsintroduktionen, men att förbättringspotential finns. Nätverksskapande är inte något som i nuläget ingår i chefsintroduktionen, men som efterfrågas av de flesta cheferna. Cheferna presenterade förbättringsförslag som ska kunna verka för att hjälpa organisationen utveckla och förbättra chefsintroduktionen ytterligar
Food Thinking : How can we reduce the food waste in the households?
No full text70% of the fresh water and 40% of the earth surface is used for agriculture purposes. Today we throw away nearly every 3rd grocery bag we buy. By doing this we waste a lot of the worlds resources. Only in Sweden we spoil 1.2 billion tons of food every year. 700 000 tons of this is from the households. The biggest source to the waste is single households and families with children, this became the target group for this project. We have to change our behavior to preserve the earth’s resources. The research showed that the biggest reasons that we throw so much food is that we first of all buy too much food. We don’t have time to eat all the food we buy and it get therefore spoiled. This is a consequence from that we don’t see it as a problem. There is a lack of knowledge in how much we throw away and how to store food correctly. We are bad at planning our meals and grocery shopping and we end up with too much food because of this. This project investigates how we can reduce the food waste. The analyzed problem areas was used as a starting point in the ideation. The project focus is during the storing of the food in the households and how to keep track on the food we have. The storing of the food can be divided in three parts, make food last longer, plan the meals and shopping and keep track on the food we have. The final result is the smart food storage. It is a concept that helps the user to get a good overview of the food and to store it in the optimized way. It enables for planning of grocery shopping and helps you keep track on the food you have
The Minimum Wage and a Non-Competitive Market for Qualifications
No full textIn this paper we consider an equilibrium model of demand and supply for several qualifications first in a competitive setting and then in a non-competitive setting. We propose a tractable analytical framework, i.e. when workers choose between qualifications according to a multinomial logit model of choice and when a CES production function describes the substitutions possibilities between the different types of labour. While in the competitive case the effects of the minimum wage are those we expect, in the imperfectly competitive case we find that a minimum wage can create unemployment and we find that the welfare of the population as a function of the minimum wage is not unimodal. We show furthermore that allowing one qualification to be exempted from the minimum wage does not mean that its relative demand is unaffected by changes to the minimum wage
Drosophila melanogaster transcriptional response to Nora virus infection
No full textPathogens induce the activation and suppression of several genes, including potent immune response genes in Drosophila melanogaster. Although several different immune response pathways have been shown to play important roles in the defense against viruses, most of these responses are virus-specific and there appears to be no pathway or set of genes that are induced in response to all viruses. We have here identified genes that are differentially expressed in Drosophila melanogaster in response to Nora virus infection. Our results indicate that none of the known immune response pathways are induced following Nora virus infection, but among the upregulated genes we find three members of the same family as CHKov1 and CHKov2 (ref(3)D), which are involved in resistance to the σ virus. Although Nora virus is a known target of the RNAi pathway, none of the genes belonging to this antiviral system were affected. On the contrary, known immunity responders, such as targets of the Toll and Imd pathways, were downregulated. Several heat-shock proteins, which are usually activated in response to external stimuli, are induced during Nora virus infection. Strikingly, several stress response genes, chaperones and genes required for repair were induced, while digestive enzymes and proteins involved in nutrient uptake and transport were shut down
