Affärs- och chefscoaching ? Framtidens företagsutveckling?
During later years coaching has gained popularity. Coaching offers help to learn rather than to teach and enables optimal performance. The method that builds consciousness, strengthens choices and leads to change in the wanted direction, can deduce to some of history's most successful educationalists. A coaching area steadily increasing is business- and executive coaching. The overall purpose with this paper is to explain what coaching is generally speaking, with specific focus on business- and executive coaching.
Förstudie för en vindkraftpark på Malmölandet i Norrköping : En undersökning av förutsättningarna för en vindkraftpark på ett sen tidigare planerat område
This is a feasibility study that examines various aspects of building a wind farm on Malmön in Norrköping. The feasibility study deals with interests of conflict, park design, electrical connections, production calculation, financial calculations and operating- and timetable.The report is divided into two distinct parts. First a theoretical part, which deals with conflicting interests, park design and electrical connections. Second a part with simulations dealing with production calculations, and financial calculations.Opposing interests are mapped so that problem areas can be found, and help put focus on the right places at a future environmental impact assessment (EIA). There are a number of areas where planners have to assess on an EIA, this thesis point on the most important areas.
Värdet av tystnad : en värderingsstudie över Upplands Väsbybornas betalningsvilja för reducerat flygbuller
Since the spring 2003 the tenant-owner home association the Terrace in Upplands Väsby municipality lies straight under the approach route to Arlanda Airport?s new third landing chute. Noise levels of over 70 dB have been measured in the area, which exceeds National Board of Housing?s, values for traffic noise at a terrace in connection to housing.
By using the method of hedonisk pricing the essay tries to find out if there exists a willingness to pay to reduce the noise in the area.
Pedagogiska miljöer : Barns och pedagogers uppfattningar om den pedagogiska miljöns erbjudande utifrån ett genusperspektiv
Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.
Har fondstorleken någon betydelse? : En jämförande studie mellan fondstorlek och prestation
Det stora allmänna intresset för att spara i fonder är stort i Sverige. Detta har bidragit till att mer pengar kommit in på marknaden och många fonder växt sig större.Tidningarna skriver att det gått bäst för små, oberoende fondförvaltare som gång på gång slagit storbankerna i undersökningar om vilka fonder som lyckats slå index och som ger bäst avkastning.Tidigare studier som gjorts om fondstorlekens betydelse för dess prestation visar en effektivitetsförlust på ett väldigt tidigt stadium då fonden växer sig större. Detta på grund av att små fonder kan vara mer flexibla än stora fonder.Syftet med uppsatsen är att jämföra aktiefonder med varandra och se om storleken på fonden har betydelse för dess prestation. En undersökning genomförs för att se om små fonder ger bättre avkastning än stora fonder.För undersökningen har data valts att insamlas från alla Sverigefonder på den svenska marknaden som funnits sedan 2002 fram till år 2006. En storleksindelning av fonderna har skett för att utgöra uppsatsens beräkningsunderlag.
Does social activity and management routines affect the horses interest for humans? :
This work focuses on the relation between human and animals and especially on the relation between horses and human. I have brought up the human och horse relationsship, today, and in history and wrote about the behaviour of the horse. Some older studies with human and animal interaction, including animals like dog and cattle are discussed. I have also discussed physiological parameters that might influence the bond and the interaction between human and horse and some critical aspects concerning the methodology when studying this kind of physiology.
The purpose of the experimental study was to analyze if common management routines and grooming of horses increases horses interest in making contact with humans. Many horse owners feel that they have a good connection with their horse and factors that can influence the relationsship could be physical contact, feeding or some challange that make the horse trust the human.
Begomovirus susceptibility in wild Nicaraguan tomato populations
Tomato production is a common and important agricultural activity in Nicaragua. During the last decades tomato producers have suffered great yield losses due to begomoviruses (family Geminiviridae). The genome of begomoviruses generally consists of two circular ssDNA components, DNA-A and DNA-B. Tomato yellow leaf curl virus (TYLCV) is an example of a begomovirus with only one component. An approach to manage the virus epidemics has been to breed a cultivar with begomovirus resistance genes, which have been transferred from wild tomato.
Tillväxtreaktion på kvarlämnade träd i Hagners "Naturkultur" försök :
The primary goal of this study was to investigate how the radial growth of retained trees responds after thinning-from-above. The National Board of Forestry which initiated this study, was interested in whether there were differences in the growth-response between the tree species Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.). Another question of issue was if there were differences in the growth response between trees of different sizes. It is within the framework of the National Board of Forestry?s, Continuous Forests Project that these urgent questions are to be answered.
Pig behaviour during crowding : a study in organic and conventional herds
Rearing in organic pig production differs from conventional rearing; pigs have outdoor access and larger space allowances. Regardless of production system all pigs are transported before slaughter and during transport pigs are crowded together in a new environment and in a space smaller than they are used to. As pigs in organic herds are reared at even larger space allowances than conventional pigs, such crowding could possibly have a stronger impact on pig behaviour and well-being. Six pig producing herds, three conventional and three organic, were visited and pigs from each herd were enclosed during 12 minutes in a test area corresponding to the crowding on a transport vehicle. During the crowding, pigs? behaviour was observed, before and after enclosure in the test area skin lesion scores were recorded, and also measures of heart girth (for weight estimation) was done.
Tillväxt och potentiell sågtimmerkvalitet i gallringsmogna jämförelseplanteringar med Pinus contorta och P. sylvestris :
The Swedish Cellulosa Companiy, SCA, has today 280 000 ha planted with lodgepole pine (Pinus contorta var. latifolia) (?C?) which is equivalent to 14 % of its total forest area. Exotic lodgepole pine has in previous experimental stands shown a superior growth than the native Scots pine (Pinus sylvestris L.) (?S?).But also the comparison could be questioned because stand histories were was unknown and also differences in age between C and S existed.
Svenska kronan, en potentiell safe haven? : En undersökning om den svenska kronans karaktär efter den finansiella krisen
Tack vare Sveriges bibehållet starka inhemska ekonomi i kölvattnet av finanskrisen 2008-2010 har en diskussion angående svenska kronans eventuella övergång från en procyklisk tillgång till en säker tillgång förts. Samtidigt har det inom populärvetenskap och bland yrkesmän även uttryckts åsikter mot detta påstående. Tidigare studier har gjorts på den amerikanska dollarns roll som safe haven, både genom analys av dess trend före jämfört med efter signifikanta globala händelser men även genom att undersöka dess betingade kovarians gentemot andra valutor. Liknande studier har dock inte genomförts lika grundligt för den svenska kronan efter finanskrisen. Denna uppsats syftar därmed att utröna om någon signifikant förändring i svenska kronans karaktär kan ses före och efter centrala händelser under finanskrisen.
Truppgymnastik
According to recent research the basics for a good body posture is balance between the muscles, if unbalance originates this can be strengthen by gymnastics when most of the practise performs only in one direction. Because of limited research in the area was an explorative study conducted. The purpose of the study was to inquire if exercise adjusted to the individual contributes for balanced muscles and if it contributes for a positive or negative development for the team.On the basics of that the team is not equable an other team in the area has the results for two different periods been measured, during the first period the exercise continued as usual but during the second period each gymnast (n=9) received an individual strength- and stretch program that was performed during the teampractise twice a week. The gymnasts were tested in areas that are imported for them as body posture, balance between the muscles, vigour, range of movement, balance, the running and coordination. The results showed on that the difference is largest between test two and three, except the coordination and balance which did not show any particular change.
Kronunionens återkomst : En empirisk underso?kning av konjunkturscykler, arbetskraftsro?rlighet och handelsintegration fo?r att avgo?ra mo?jligheten att info?ra en gemensam valuta i Norden
This paper is an assessment of whether the Nordic countries constitute an optimum currency area (OCA) or not. Hodrick Prescott-?filtered data of real Gross Domestic Product (GDP) and rate of employment are used to investigate the similarity of business cycles between the target countries through a series of correlation analysis with Sweden as the base reference country and also by using a linear regression model. Additionally there is an evaluation of trade volume and labour mobility between the countries. Our results indicate that Iceland had the least similar business cycles within the Nordic countries and that the area should therefore possibly comprise Denmark, Finland, Norway and Sweden. .
Hållbar utveckling + turism = sant? Intressen inom projektet Exportmogen destination i biosfärområdet Vänerskärgården med Kinnekulle
This essay examines whether, and if so to which extent, the project Export MatureDestination in the Biosphere Reserve Vänerskärgården with Kinnekulle can combine the goalof the tourism industry, i.e. to double tourism between 2010 and 2020, and the goals of theBiosphere reserve, i.e. sustainable societal development and a sustainable biosphere economy.The aim is to examine how key individuals in the project approach sustainable developmentand economic growth, representing the two main interests in the area. Examining the state ofthe two interests the following examples are used: the position of sustainable development inregard to economic growth, the opportunities and challenges in the area and unity concerningthe goals of the tourism development in the region. The study is conducted through qualitativeinterviews with key individuals and a descriptive document analysis of the most importantpolicy documents.
