Påverkar kvinnor i bolagsstyrelser bolagens lönsamhet? : En svensk studieValmila, Daniel, Mellberg, Eric January 2015 (has links)
I den politiska debatten är jämställdhetsfrågan ett ständigt diskussionsämne. Även EU uppmärksammar detta och lägger fram ett förslag som innebär att minst 40 % av styrelseledamöterna ska vara kvinnor år 2020. Det finns flertalet internationella studier som undersöker om det finns något samband mellan kvinnor i bolagsstyrelsen och bolagens lönsamhet, resultaten är varierande. Med detta i åtanke inriktar sig studiens syfte åt att undersöka om det finns något samband mellan de två variablerna i de svenska aktiebolagen noterade på Large Cap-listan. Denna uppsats använder sig av en kvantitativ metod. Lönsamhetsmåttet som granskas i denna studie är räntabilitet på totalt kapital och jämställdhetsmåttet är andelen kvinnor, denna information hämtas ifrån bolagens årsredovisningar. För att undersöka om kvinnor i bolagsstyrelserna samvarierar med bolagens lönsamhet används Pearsons korrelationsanalys. Studien konstaterar att det inte finns något samband mellan de två variablerna som är kvinnor i bolagsstyrelser och bolagens lönsamhet hos de svenska Large Cap-bolagen. Anledningen till detta kan vara att kvinnorna i bolagsstyrelserna är en minoritet, vilket innebär att det blir svårt för de att påverka lönsamheten. Kvinnor i bolagsstyrelserna kan dock bidra med andra positiva effekter som i sin tur är värdeskapande för organisationerna. Denna uppsats undersöker ej om det finns någon kausalitet mellan variablerna. Detta är något som vidare forskning bör ta hänsyn till. Ytterligare ett förslag är att involvera fler lönsamhetsmått i sin undersökning för att få en heltäckande bild över bolagens lönsamhet. Uppsatsen visar på att det ej finns något samband mellan kvinnor i bolagsstyrelser och bolagens lönsamhet. Detta visar på att bolagen ej kan höja sin lönsamhet enbart genom att tillsätta kvinnor i bolagsstyrelsen.

Příspěvek na péči ve vztahu k osobám se zrakovým postižením / Care allowance in relation to the visually impaired personsZajíc, Luboš January 2011 (has links)
My master's degree thesis focuses on special Czech social security benefit, which can be perhaps called "benefit for personal care". In the first chapter I explicate the topic and conceptions I will work with in the following text. The second chapter describes legislation which precedes the Act of social services containing the "benefit for personal care". This Act had come in force in 2006 and has come into effect since 1st January 2007. I compared construction of previous supports and " benefit for personal care" The third chapter explains in detail rules of law which regulate conditions of claim for benefit for personal care, administrative procedure, etc. The level of benefit relates to the degree in which needy person depends on help of other individual. The method used for establishing this degree is highlighted in the 4th chapter. The 4th chapter is subdivided into two major parts according to operations and procedures used to establish degree of applicant's dependence. I especially focused on aspects of establishing proper degree of dependence for visually impaired people. In final part I reflected on alternative ways how to regulate this social security issue based on a reflection of functioning of chosen system and I have mentioned the latest novel social service Act which will come into...

Nonparametric criteria for sparse contingency tables / Neparametriniai kriterijai retų įvykių dažnių lentelėmsSamusenko, Pavel 18 February 2013 (has links)
In the dissertation, the problem of nonparametric testing for sparse contingency tables is addressed.
Statistical inference problems caused by sparsity of contingency tables are widely discussed in the literature. Traditionally, the expected (under null the hypothesis) frequency is required to exceed 5 in almost all cells of the contingency table. If this condition is violated, the χ2 approximations of goodness of fit statistics may be inaccurate and the table is said to be sparse . Several techniques have been proposed to tackle the problem: exact tests, alternative approximations, parametric and nonparametric bootstrap, Bayes approach and other methods. However they all are not applicable or have some limitations in nonparametric statistical inference of very sparse contingency tables.
In the dissertation, it is shown that, for sparse categorical data, the likelihood ratio statistic and Pearson’s χ2 statistic may become noninformative: they do not anymore measure the goodness-of-fit of null hypotheses to data. Thus, they can be inconsistent even in cases where a simple consistent test does exist.
An improvement of the classical criteria for sparse contingency tables is proposed. The improvement is achieved by grouping and smoothing of sparse categorical data by making use of a new sparse asymptotics model relying on (extended) empirical Bayes approach. Under general conditions, the consistency of the proposed criteria based on grouping is proved. Finite-sample behavior of... [to full text] / Disertacijoje sprendžiami neparametrinių hipotezių tikrinimo uždaviniai išretintoms dažnių lentelėms.
Problemos, susijusios su retų įvykių dažnių lentelėmis yra plačiai aptartos mokslinėje literatūroje. Yra pasiūlyta visa eilė metodų: tikslieji testai, alternatyvūs aproksimavimo būdai parametrinė ir neparametrinė saviranka, Bayeso ir kiti metodai. Tačiau jie nepritaikomi arba yra neefektyvūs neparametrinėje labai išretintų dažnių lentelių analizėje.
Disertacijoje parodyta, kad labai išretintiems kategoriniams duomenims tikėtinumo santykio statistika ir Pearsono χ2 statistika gali pasidaryti neinformatyviomis: jos jau nėra tinkamos nulinės hipotezės ir duomenų suderinamumui matuoti. Vadinasi, jų pagrindu sudaryti kriterijai gali būti net nepagrįsti net tuo atveju, kai egzistuoja paprastas pagrįstas kriterijus.
Darbe yra pasiūlytas klasikinių kriterijų patobulinimas išretintų dažnių lentelėms. Siūlomi kriterijai remiasi išretintų kategorinių duomenų grupavimu ir glodinimu naudojant naują išretinimo asimtotikos modelį, kuris remiasi (išplėstine) empirine Bayeso metodologija. Prie bendrų sąlygų yra įrodytas siūlomų kriterijų, naudojančių grupavimą, pagrįstumas. Kriterijų elgesys baigtinių imčių atveju tiriamas taikant Monte Carlo modeliavimą.
Disertacija susideda iš įvado, 4 skyrių, literatūros sąrašo, bendrų išvadų ir priedo.
Įvade atskleidžiama nagrinėjamos mokslinės problemos svarba, aprašomi darbo tikslai ir uždaviniai, tyrimo metodai, mokslinis naujumas, praktinė gautų... [toliau žr. visą tekstą]

En utvärdering av IT-investeringar på banker med fokus på IT-styrningsmetoder / An evaluation of the archetypes in banking and its impact on IT investmentsAfaneh, Mashour January 2011 (has links)
This report discusses the IT archetypes "governance strategy" and how it could be linked to the IT benefits at the company. The study is based on IT investments that have taken place in ten banks operating in Sweden today, where the reality was modeled on the basis of a questionnaire survey and an additional interview. The aim was to examine whether it is possible to find any correlation between the governance in the banks and obtained benefits for an IT investments. While the competition is intensifying in most companies there is a greater demand for efficiency in IT. The need for IT solutions is greater than ever and the number of IT investments is increasing significantly in most workplaces today, especially on banks. But even if the investments are increasing in numbers it does not necessarily mean that all types of investments are effective and beneficial to the company. The benefits of IT investments are often difficult to measure, and the calculations become even more complex the larger the organization is. According to the framework Val IT Framework 2.0, from 2008, there was a global study made by Price Waterhouse Coopers in Belgium. The surveys, which were based on the response of 750 IT executives and managers, showed that the importance of IT is increasing and that there is much room for improvements in terms of returns on IT investments. To make it easier finding the underlying structures the study was divided into two parts, one benefit study and one archetype study. The structure of both the studies is based on research done by Peter Weill and Jeanne Ross in the field of IT governance and research in IT benefits by Gunasekaran. The main purpose of this report is to present a new way of thinking - where banks can predict the benefits of an IT investment just by viewing their corporate governance and invest in the most profitable IT investments only. The results of this study shows that there are some relations between received benefits in IT investments on the examined banks and their archetype. Most of the banks have an archetype that is similar to the IT duopoly and investments which generally results in strategic benefits.
