Portfolion allokointi Euroopan markkinoilla: toimiala- vai maakohtainen strategia?

Tutkimuksen tarkoituksena on selvittää, kumpi on suomalaisen sijoittajan näkökulmasta tehokkaampi tapa allokoida portfolio Euroopan alueelle, maa- vai toimialalähestymistapa. Tätä tutkitaan käyttämällä aineistoa vuosilta 1999-2003. Tilanne ennen vuotta 1999 on aikaisempien tutkimusten perusteella melko hyvin selvillä, joten tutkimus antaa tuoretta tietoa siitä, miten poikkeuksellinen tuottohistoria vaikuttaa portfolion allokointiin. Aihetta tutkitaan käyttämällä 16 Euroopan alueen maaindeksiä ja kymmentä toimialaindeksiä. Indeksit ovat logaritmisia nettotuottoindeksejä, ja niistä on laskettu korrelaatiot, keskihajonnat sekä tehokkaat rintamat. Indekseistä on myös muodostettu 11 esimerkkiportfoliota, joiden avulla on analysoitu erilaisten portfolioiden suorituskykyä. Tuloksien mukaan maakohtaisella sijoitusstrategialla on etenkin laskevilla markkinoilla mahdollisuus saavuttaa parempi riski/tuotto-suhde, vaikka sijoitettaisiin pelkästään toimialoihin, joita yleisen käsityksen mukaan kannattaa suosia laskevilla markkinoilla. Toimialasijoittaminen taas tarjoaa hieman parempia mahdollisuuksia portfolion hajautukseen. Hajautuksen hyödyt suomalaiselle sijoittajalle tulivat tutkimuksessa selvästi esiin. Toimialasijoittamisesta on suomalaiselle sijoittajalle erityistä hyötyä hajautuksen kannalta, koska näin voidaan valita toimialoja, joiden paino Suomen markkinaindeksissä on vähäinen.

Ydinvoimalaitoksen höyryturbiinin suorituskyvyn laskenta

Diplomityön tavoitteena on selvittää Loviisan ydinvoimalaitoksen höyryturbiinin hyötysuhteen parantamismahdollisuuksia. Työn kuvaan liittyvät oleellisesti höyryturbiinin siipivyöhykkeiden nopeuskolmioiden sekä hyötysuhteiden laskenta. Höyryturbiinien kehityskaarta sekä turbiinin häviökerrointen laskentayhtälöitä on esitetty useasta eri lähteestä ja vuosikymmeniltä. Työssä selvitettiin uusimpia ydinvoimalaitosten kostea höyryturbiinien suunnitteluperusteita lukuisista eri lähteistä. Kaikkien lähteiden mukaan kostean höyryn alueella tapahtuvaa paisuntaa on haasteellista mallintaa. Työssä on esitelty artikkeleissa tulleita eri näkökulmia höyryturbiinien suorituskyvyn parantamiseksi, sekä rakenteellisia että laskennallisia. Työssä esitellään monia turbiinin virtauksen ja suorituskyvyn laskentamenetelmiä. Esimerkiksi Baumannin säännön laskenta on yksinkertainen tapa käsitellä turbiinin suorituskykyä kostean höyryn alueella. Keskeisimpiä tehtyjä havaintoja oli se, että korkeapaineturbiinin ensimmäisestä vaiheesta löytyi mahdollista parannuspotentiaalia Loviisaan ydinvoimalaitoksen tehon lisäämiseksi. Ensimmäisessä vaiheessa on oletettu siipien olevan Laval –tyyppisiä, mutta käytännössä näin ei ole. Korkeapaineturbiinin nykyisen turbosuuttimen toimintaa voitaisiin tehostaa. Lisäksi Loviisan matalapaineturbiinin viimeisen siipivaiheen jälkeen aiheutuu suuret ulosvirtaushäviöt. Osa suurinopeuksisen virtauksen energiasta pystyttäisiin kuitenkin hyödyntämään vielä ulosvirtauskanavassa olevalla diffuusorilla.

Energiatiedon hallintajärjestelmän suorituskyvyn määrittäminen ja todentaminen

Sähkömarkkinoiden vapautumisen jälkeen energia-alalle on muodostunut entistä suurempi kysyntä kehittyneille energiatiedon hallintaaan erikoistuneille tietojärjestelmille. Uudet lakisäädökset sekä tulevaisuuden kokonaisvaltaiset tiedonkeruujärjestelmät, kuten älykkäät mittarit ja älykkäät sähköverkot, tuovat mukanaan entistä suuremman prosessoitavan tietovirran. Nykyaikaisen energiatietojärjestelmän on kyettävä vastaamaan haasteeseen ja palveltava asiakkaan vaatimuksia tehokkaasti prosessien suorituskyvyn kärsimättä. Tietojärjestelmän prosessien on oltava myös skaalautuvia, jotta tulevaisuuden lisääntyneet prosessointitarpeet ovat hallittavissa. Tässä työssä kuvataan nykyaikaisen energiatietojärjestelmän keskeiset energiatiedon hallintaan ja varastointiin liittyvät komponentit. Työssä esitellään myös älykkäiden mittareiden perusperiaate ja niiden tuomat edut energia-alalla. Lisäksi työssä kuvataan visioita tulevaisuuden älykkäiden sähköverkkojen toteutusmahdollisuuksista. Diplomityössä esitellään keskeisiä suorituskykyyn liittyviä kokonaisuuksia. Lisäksi työssä kuvataan keskeiset suorituskyvyn mittarit sekä suorituskykyvaatimukset. Järjestelmän suorituskyvyn arvioinnin toteuttamiseen on erilaisia menetelmiä, joista tässä työssä kuvataan yksi sen keskeisine periaatteineen. Suorituskyvyn analysointiin käytetään erilaisia tekniikoita, joista tässä diplomityössä esitellään tarkemmin järjestelmän mittaus. Työssä toteutetaan myös case-tutkimus, jossa analysoidaan mittaustiedon sisääntuontiin käytettävän prosessin kahta eri kehitysversiota ja näiden suorituskykyominaisuuksia. Kehitysversioiden vertailussa havaitaan, että uusi versio on selkeästi edellistä versiota nopeampi. Case-tutkimuksessa määritetään myös suorituskyvyn kannalta optimaalinen rinnakkaisprosessien määrä ja tutkitaan prosessin skaalautuvuutta. Tutkimuksessa todetaan, että uusi kehitysversio skaalautuu lineaarisesti.

Nursing Ethics Education in Finland from the Perspective of Codes of Ethics

The purpose of this study was to analyze nursing ethics education from the perspective of nurses’ codes of ethics in the basic nursing education programmes in polytechnics in Finland with the following research questions: What is known about nurses’ codes in practice and education, what contents of the codes are taught, what teaching and evaluation methods are used, which demographic variables are associated with the teaching, what is nurse educators’ adequacy of knowledge to teach the codes and nursing students’ knowledge of and ability to apply the codes, and what are participants’ opinions of the need and applicability of the codes, and their importance in nursing ethics education. The aim of the study was to identify strengths and possible problem areas in teaching of the codes and nursing ethics in general. The knowledge gained from this study can be used for developing nursing ethics curricula and teaching of ethics in theory and practice. The data collection was targeted to all polytechnics in Finland providing basic nursing education (i.e. Bachelor of Health Care). The target groups were all nurse educators teaching ethics and all graduating nursing students in the academic year of 2006. A total of 183 educators and 214 students from 24 polytechnics participated. The data was collected using a structured questionnaire with four open-ended questions, designed for this study. The data was analysed by SPSS (14.0) and the open-ended questions by inductive content analysis. Descriptive statistics were used to summarize the data. Inferential statistics were used to estimate the differences between the participant groups. The reliability of the questionnaire was estimated with Cronbach’s coefficient alpha. The literature review revealed that empirical research on the codes was scarce, and minimal in the area of education. Teaching of nurses’ codes themselves and the embedded ethical concepts was extensive, teaching of the functions of the codes and related laws and agreements was moderate, but teaching of the codes of other health care professions was modest. Issues related to the nurse-patient relationship were emphasised. Wider social dimensions of the codes were less emphasized. Educators’ and students’ descriptions of teaching emphasized mainly the same teaching contents, but there were statistically significant differences between the groups in that educators assessed their teaching to be more extensive than what students had perceived it had been. T he use of teaching and evaluation methods was rather narrow and conventional. However, educators’ and students’ descriptions of the used methods differed statistically significantly. Students’ knowledge of the codes and their ability to apply them in practice was assessed as mediocre by educators and by students themselves. Most educators assessed their own knowledge of the codes as adequate to teach the codes, as did most of the students. Educators who regarded their knowledge as adequate taught the codes more extensively than those who assessed their knowledge as less adequate. Also students who assessed their educators’ knowledge as adequate perceived the teaching of the codes to be more extensive. Otherwise educators’ and students’ demographic variables had little association with their descriptions of the teaching. According to the participants, nurses need their own codes, and they are also regarded as applicable in practice. The codes are an important element in nursing ethics education, but their teaching needs development. Further research should focus on the organization of ethics teaching in the curricula, the teaching process, and on the evaluation of the effectiveness of ethics education and on educators’ competence. Also the meaning and functions of the codes at all levels of nursing deserve attention. More versatile use of research methods would be beneficial in gaining new knowledge.

CFD Simulation of Two-phase and Three-phase Flows in Internal-loop Airlift

Airlift reactors are pneumatically agitated reactors that have been widely used in chemical, petrochemical, and bioprocess industries, such as fermentation and wastewater treatment. Computational Fluid Dynamics (CFD) has become more popular approach for design, scale-up and performance evaluation of such reactors. In the present work numerical simulations for internal-loop airlift reactors were performed using the transient Eulerian model with CFD package, ANSYS Fluent 12.1. The turbulence in the liquid phase is described using κ- ε the model. Global hydrodynamic parameters like gas holdup, gas velocity and liquid velocity have been investigated for a range of superficial gas velocities, both with 2D and 3D simulations. Moreover, the study of geometry and scale influence on the reactor have been considered. The results suggest that both, geometry and scale have significant effects on the hydrodynamic parameters, which may have substantial effects on the reactor performance. Grid refinement and time-step size effect have been discussed. Numerical calculations with gas-liquid-solid three-phase flow system have been carried out to investigate the effect of solid loading, solid particle size and solid density on the hydrodynamic characteristics of internal loop airlift reactor with different superficial gas velocities. It was observed that averaged gas holdup is significantly decreased with increasing slurry concentration. Simulations show that the riser gas holdup decreases with increase in solid particle diameter. In addition, it was found that the averaged solid holdup increases in the riser section with the increase of solid density. These produced results reveal that CFD have excellent potential to simulate two-phase and three-phase flow system.

Hissien tasonovien palotestauspalveluiden arviointi.

Elevator landing doors are fire tested to measure their fire resistance. The objective of this master’s thesis was to create a method to evaluate the fire tests and the organizations that provide these testing services. The main focus area was in creating accurate evaluation criteria and weighting the criteria. The thesis was formed by first presenting the reader with the literature review of the closest related theories. The theories which were chosen were systematic decision making, supplier selection, and make or buy and outsourcing theories. In the empirical section the created process of evaluating fire testing is presented, with analysis of the current situation of fire testing processes and evaluation methods. Evaluating fire testing services required two types of criteria to be formed, technical criteria to evaluate the technical requirements, and service criteria to evaluate the organization which was offering the testing service. These criteria formed the core for the evaluation process which consisted of five different phases that were developed based on the literature review. The process was tested to create best practices and to make improvement proposals accordingly. Systematical process for evaluating fire testing helps to recognize the most important technical and service related aspects. The created criteria can be also used in future to benchmark and monitor the situation of fire testing. The results of the process can be used when deciding whether to outsource the service or to keep it in-house.

Excelling in procurement : IT Contract Management with Lean and Six Sigma. Case study on legacy contract management at Philips Global IT.

Few people see both opportunities and threats coming from IT legacy in current world. On one hand, effective legacy management can bring substantial hard savings and smooth transition to the desired future state. On the other hand, its mismanagement contributes to serious operational business risks, as old systems are not as reliable as it is required by the business users. This thesis offers one perspective of dealing with IT legacy – through effective contract management, as a component towards achieving Procurement Excellence in IT, thus bridging IT delivery departments, IT procurement, business units, and suppliers. It developed a model for assessing the impact of improvements on contract management process and set of tools and advices with regards to analysis and improvement actions. The thesis conducted case study to present and justify the implementation of Lean Six Sigma in IT legacy contract management environment. Lean Six Sigma proved to be successful and this thesis presents and discusses all the steps necessary, and pitfalls to avoid, to achieve breakthrough improvement in IT contract management process performance. For the IT legacy contract management process two improvements require special attention and can be easily copied to any organization. First is the issue of diluted contract ownership that stops all the improvements, as people do not know who is responsible for performing those actions. Second is the contract management performance evaluation tool, which can be used for monitoring, identifying outlying contracts and opportunities for improvements in the process. The study resulted in a valuable insight on the benefits of applying Lean Six Sigma to improve IT legacy contract management, as well as on how Lean Six Sigma can be applied in IT environment. Managerial implications are discussed. It is concluded that the use of data-driven Lean Six Sigma methodology for improving the existing IT contract management processes is a significant addition to the existing best practices in contract management.

Chromatographic recovery of chemicals from acidic biomass hydrolysates

Lignocellulosic biomasses (e.g., wood and straws) are a potential renewable source for the production of a wide variety of chemicals that could be used to replace those currently produced by petrochemical industry. This would lead to lower greenhouse gas emissions and waste amounts, and to economical savings. There are many possible pathways available for the manufacturing of chemicals from lignocellulosic biomasses. One option is to hydrolyze the cellulose and hemicelluloses of these biomasses into monosaccharides using concentrated sulfuric acid as catalyst. This process is an efficient method for producing monosaccharides which are valuable platforn chemicals. Also other valuable products are formed in the hydrolysis. Unfortunately, the concentrated acid hydrolysis has been deemed unfeasible mainly due to high chemical consumption resulting from the need to remove sulfuric acid from the obtained hydrolysates prior to the downstream processing of the monosaccharides. Traditionally, this has been done by neutralization with lime. This, however, results in high chemical consumption. In addition, the by-products formed in the hydrolysis are not removed and may, thus, hinder the monosaccharide processing. In order to improve the feasibility of the concentrated acid hydrolysis, the chemical consumption should be decreased by recycling of sulfuric acid without neutralization. Furthermore, the monosaccharides and the other products formed in the hydrolysis should be recovered selectively for efficient downstream processing. The selective recovery of the hydrolysis by-products would have additional economical benefits on the process due to their high value. In this work, the use of chromatographic fractionation for the recycling of sulfuric acid and the selective recovery of the main components from the hydrolysates formed in the concentrated acid hydrolysis was investigated. Chromatographic fractionation based on the electrolyte exclusion with gel type strong acid cation exchange resins in acid (H+) form as a stationary phase was studied. A systematic experimental and model-based study regarding the separation task at hand was conducted. The phenomena affecting the separation were determined and their effects elucidated. Mathematical models that take accurately into account these phenomena were derived and used in the simulation of the fractionation process. The main components of the concentrated acid hydrolysates (sulfuric acid, monosaccharides, and acetic acid) were included into this model. Performance of the fractionation process was investigated experimentally and by simulations. Use of different process options was also studied. Sulfuric acid was found to have a significant co-operative effect on the sorption of the other components. This brings about interesting and beneficial effects in the column operations. It is especially beneficial for the separation of sulfuric acid and the monosaccharides. Two different approaches for the modelling of the sorption equilibria were investigated in this work: a simple empirical approach and a thermodynamically consistent approach (the Adsorbed Solution theory). Accurate modelling of the phenomena observed in this work was found to be possible using the simple empirical models. The use of the Adsorbed Solution theory is complicated by the nature of the theory and the complexity of the studied system. In addition to the sorption models, a dynamic column model that takes into account the volume changes of the gel type resins as changing resin bed porosity was also derived. Using the chromatography, all the main components of the hydrolysates can be recovered selectively, and the sulfuric acid consumption of the hydrolysis process can be lowered considerably. Investigation of the performance of the chromatographic fractionation showed that the highest separation efficiency in this separation task is obtained with a gel type resin with a high crosslinking degree (8 wt. %); especially when the hydrolysates contain high amounts of acetic acid. In addition, the concentrated acid hydrolysis should be done with as low sulfuric acid concentration as possible to obtain good separation performance. The column loading and flow rate also have large effects on the performance. In this work, it was demonstrated that when recycling of the fractions obtained in the chromatographic fractionation are recycled to preceding unit operations these unit operations should included in the performance evaluation of the fractionation. When this was done, the separation performance and the feasibility of the concentrated acid hydrolysis process were found to improve considerably. Use of multi-column chromatographic fractionation processes, the Japan Organo process and the Multi-Column Recycling Chromatography process, was also investigated. In the studied case, neither of these processes could compete with the single-column batch process in the productivity. However, due to internal recycling steps, the Multi-Column Recycling Chromatography was found to be superior to the batch process when the product yield and the eluent consumption were taken into account.

The results of this study indicate that the comparing systems provide usable interfaces, and WordPress is recognized as the most usable system.

Johdon laskentatoimen ohjaus- ja hallintajärjestelmien hyödyntäminen yritysverkostoissa

Tutkimuksen aiheena on johdon laskentatoimen ohjaus- ja hallintajärjestelmien hyödyntäminen yritysverkostoissa. Yritysten välisten suhteiden hallinnassa käytettävät menetelmät koostuvat pääasiassa johdon laskentatoimen ja suorituskyvyn mittaamisen menetelmistä. Verkostojen ohjaus ja hallinta on tärkeää, koska se on verkostojen tehokkaan toiminnan kriittinen menestystekijä ja kilpailuedun lähde. Suorituskyvyn mittaamisella, johdon laskentatoimella ja johdon kontrollitehtävällä on keskenään riippuvuussuhteet, joiden pitäisi toimia sopusoinnussa. Suorituskyvyn mittaamisen ja johdon laskentatoimen tutkimus yritysten verkostoympäristöissä on kohtalaisen tuore ilmiö, jonka vuoksi aihealueen tutkimus on vielä varsin pirstaleista ja hajanaista. Tämän vuoksi tutkimuksen tavoite on muodostaa selkeä kokonaiskuva siitä kuinka johdon laskentatoimen ohjaus- ja hallintajärjestelmiä voidaan hyödyntää yritysverkostojen ohjauksessa ja hallinnassa. Tutkimuksessa myös selvitetään mitä haasteita näiden menetelmien hyödyntämiseen yritysverkostoissa sisältyy. Tutkimusaineistona on käytetty aikaisempia tutkimuksia sekä tutkimusta varten tehtyjä haastatteluita. Tutkimukseen haastateltiin neljästä yritysverkostosta henkilöitä, jotka vastasivat verkoston toiminnasta. Haastatteluiden avulla pyritään täydentämään kirjallisuuskatsauksen pohjalta luotua teoriaa ja selvittämään kuinka verkoston ohjaus- ja hallinta hoidetaan haastateltavissa verkostoissa, millä menetelmin ja mitä haasteita siihen liittyy. Verkostotoimintaan soveltuvien menetelmien ja suorituskykymittareiden kehittäminen on hankalaa, koska jokaisen verkoston tarpeet ja haasteet ovat erilaiset. Uusien menetelmien kehittämiselle ei nähdä tarvetta, vaan kyse on olemassa olevien menetelmien soveltamisesta verkostonäkökulmasta. Menetelmät on rakennettu yksittäisen yrityksen mittaamiseen, joten ne eivät sovellu sellaisenaan käytettäväksi verkostoihin, vaan niitä täytyy kehittää verkoston yksilöllisten tarpeiden mukaan. Tämä vaatii kuitenkin verkostolta osaamista ja halua kehittyä. Verkostojen haasteet liittyvät sekä yritystasolle että verkostotasolle. Yritysten tuottaman informaation, laskentajärjestelmien, tietotaidon, resurssien ja kehityshalun tulee olla hyvällä tasolla, jotta koko verkoston mittaaminen onnistuu luotettavasti. Lisäksi verkostotoiminta pitää sisällään laskentateknisiä, menetelmiin ja informaation vaihtamiseen liittyviä haasteita. Verkostoympäristön laskentatoimen tutkimuksessa ei ole yhtenäistä, laajasti hyväksyttyä teoriaa, koska tutkimussuuntaukset ja –tulokset ovat moniulotteisia ja vaihtelevia.

Nurse Competence of Graduating Nursing Students

The competence of graduating nursing students is an important issue in health care as it is related to professional standards, patient safety and the quality of nursing care. Many changes in health care lead to increased demand with respect to nurses’ competence as well the number of nurses. The purpose of this empirical study was to i) describe the nurse competence areas of nursing students in Europe, ii) evaluate the nurse competence of graduating nursing students, iii) identify factors related to the nurse competence, and to iv) assess the congruence between graduating nursing students’ self-assessments and their mentors’ assessments of students’ nurse competence. The study was carried out in two phases: descriptive phase and evaluation phase. The descriptive phase focused on describing the nurse competence areas of nursing students in Europe with the help of a literature review (n=10 empirical studies and n=4 additional documents). Thematic analysis was used as the analysis method. In the evaluation phase, the nurse competence with particular focus on nursing skills of graduating nursing students (n=154) was assessed. In addition, factors related to the nurse competence were examined. Also, the congruence between graduating nursing students’ self-assessments and their mentors’ assessments of students’ nurse competence was evaluated by comparing graduating nursing students’ self-assessments with the assessments by their mentors (n=42) in the final clinical placement in four university hospitals. Descriptive statistics and inferential statistics were used to analyse the data. Based on the results, the nurse competence of nursing students in Europe consists of nine main competence areas: (1) professional/ethical values and practice, (2) nursing skills and interventions, (3) communication and interpersonal skills, (4) knowledge and cognitive ability, (5) assessment and improving quality in nursing, (6) professional development, (7) leadership, management and teamwork, (8) teaching and supervision, and (9) research utilization. Graduating nursing students self-assessed their nurse competence as good. However, when graduating nursing students’ nurse competence was assessed by their mentors, the results were poorer. Readiness for practice based on nurse education, pedagogical atmosphere on the ward, supervisory relationship between student and mentor and being in paid work in health care at the moment of the study were the most significant factors related to the nurse competence. Conclusions: Nurse competence can be evaluated with a scale based on self-assessment, but other evaluation methods could be used alongside to ensure that nurse competence can be completed and evaluated critically. Practical implications are presented for nurse education and nursing practice. In future, longitudinal research is needed in order to understand the development of nurse competence during nurse education and the transition process from a nursing student to a professional nurse.
