No full textSAMMANFATTNING Examensarbete, Human Resource Management, Ekonomihögskolan vid Linnéuniversitetet, Organisation, VT2013. Titel: ”Medarbetarsamtal – vilken funktion fyller de?” Handledare: Kjell Arvidsson Författare: Josephine Berg, Magnus Ivarsson och Martina Jonsson Examinator: Mikael Lundgren Bakgrund: Att det hålls årliga medarbetarsamtal tillhör vanligheterna på de flesta företag, såväl inom privat som inom offentlig sektor. Men är det någon mening med att ha medarbetarsamtal? Vi undrar om de finns endast för att fylla ett ceremoniellt syfte, om det är något ledningen bestämt utan att förklara varför för de anställda? Syfte: Syftet med vår studie är att försöka ta reda på hur chefer och medarbetare upplever medarbetarsamtalför att se om dessa samtal fyller någon funktion eller om de existerar någon egentlig anledning. Metod: För att besvara studiens syfte har ett induktivt angreppssätt med en kvalitativ metod valts som grund för uppsatsen. Vi har intervjuat sex medarbetare och lika många chefer. Resultat och slutsatser: Vi har i vår studie sett att många företag använder sig av medarbetarsamtal utan att de egentligen inte vet varför. Det är något som görs för att det ska göras och för att alla andra gör det. Men trots att de flesta inte vet varför de genomförs tycker våra respondenter att det är bra att de finns, om inte annat så får de lite ensamtid med sin chef och det kan vara nog så viktigt. Vi har i vår studie kommit fram till att det inte finns något entydigt svar, samtalen fyller olika funktioner i olika organisationer och för olika människor.ABSTRACT Bachelor Thesis, Human Resource Management, Linnaeus University, Organization, 2013. Title: ”Medarbetarsamtal – vilken funktion fyller de?” Supervisor: Kjell Arvidsson Author: Josephine Berg, Magnus Ivarsson och Martina Jonsson Examiner: Mikael Lundgren Background: That annual performance is held every now and then is quite usual for most companies, both in the private and public sector. But is there any point in having appraisals? We wonder if they are only there to fill a ceremonial purpose, whether it is something that the management decided without explaining why the employees? Purpose: The aim of our study is to try to find out how managers and employees are experiencing performance reviews to see if these conversations have any point or if they exist without any proper reason. Method: To answer the study's end, an inductive approach with a qualitative method was selected as the basis for the essay. We interviewed six employees and an equal number of directors. Results and conclusions: We have in our study found that many companies use appraisals but they do not really know why. It is something they do just to have it done and because others do it. But even though most do not know why they implemented our respondents think that it is good that they are, if nothing else, they get some time alone with the boss, and that may be just as important. We have in our study concluded that there is no clear answer; the appraisals serve different functions in different organizations and for different people

Fossilized anaerobic and possibly methanogenesis-fueling fungi identified deep within the Siljan impact structure, Sweden
No full textRecent discoveries of extant and fossilized communities indicate that eukaryotes, including fungi, inhabit energy-poor and anoxic environments deep within the fractured igneous crust. This subterranean biosphere may constitute the largest fungal habitat on our planet, but knowledge of abyssal fungi and their syntrophic interactions with prokaryotes and their concomitant metabolisms is scarce. Here we report findings of fossilized, chitin-bearing fungal hyphae at ~540 m depth in fractured bedrock of the Siljan impact structure, the largest crater in Europe. Strong 13C-enrichment of calcite precipitated with and on the fungi suggests formation following methanogenesis, and that the anaerobic fungi decomposed dispersed organic matter producing for example H2 that may have fueled autotrophic methanogens. An Eocene age determined for the calcite infers the first timing constraint of fossilized fungi in the continental igneous crust. Fungi may be widespread decomposers of organic matter and overlooked providers of H2 to autotrophs in the vast rock-hosted deep biosphere

Zygomycetes in Vesicular Basanites from Vesteris Seamount, Greenland Basin - A New Type of Cryptoendolithic Fungi
No full textFungi have been recognized as a frequent colonizer of subseafloor basalt but a substantial understanding of their abundance, diversity and ecological role in this environment is still lacking. Here we report fossilized cryptoendolithic fungal communities represented by mainly Zygomycetes and minor Ascomycetes in vesicles of dredged volcanic rocks (basa- nites) from the Vesteris Seamount in the Greenland Basin. Zygomycetes had not been reported from subseafloor basalt previously. Different stages in zygospore formation are documented in the studied samples, representing a reproduction cycle. Spore structures of both Zygomycetes and Ascomycetes are mineralized by romanechite-like Mn oxide phases, indicating an involvement in Mn(II) oxidation to form Mn(III,VI) oxides. Zygospores still exhibit a core of carbonaceous matter due to their resistance to degradation. The fungi are closely associated with fossiliferous marine sediments that have been introduced into the vesicles. At the contact to sediment infillings, fungi produced haustoria that penetrated and scavenged on the remains of fragmented marine organisms. It is most likely that such marine debris is the main carbon source for fungi in shallow volcanic rocks, which favored the establishment of vital colonies.
