Aktiivinen ikääntyminen

Tämän tutkimuksen tarkoitus oli tutkia hoitohenkilökunnan näkemyksiä aktiivisesta ikääntymisestä ja sen toteutumisesta Kyläsaaren Palvelukodissa. Tutkimuksen tuloksia voidaan hyödyntää aktiivisen ikääntymisen edistämisessä palvelukoti ympäristössä. Tutkimus on kvalitatiivinen, ja aineistonkeruumenetelmänä käytettiin avoimista ky- symyksistä tehtyä kyselylomaketta. Aineistonkeruu tapahtui loka- marraskuun 2013 vaihteessa ja kyselylomakkeita annetiin yhteensä 10 kappaletta. Kyselylomakkeita tuli takaisin 9 kappaletta eli vastausprosentti oli 90. Aineiston analyysissä käytettiin teemoittelua ja sanallista kuvailua. Tulosten analysoinnissa esitettiin myös suoria lainauksia hoitohenkilökunnan vastauksista. Tutkimustuloksista todettiin, että Kyläsaaren palvelukodin hoitohenkilökunnalla oli hyvin samankaltaisia käsityksiä aktiivisesta ikääntymisestä. Suurin osa oli sitä miel- tä, että aktiivista ikääntymistä on havaittavissa Kyläsaaren palvelukodissa, mutta sitä ei ole riittävästi. Tämän todettiin johtuvan henkilöstöresurssien vähyydestä ja sen aiheuttamasta kiireestä. Hoitohenkilökunta haluaisi enemmän aikaa, jotta he pystyisivät järjestämään enemmän toimintaa asukkaille

ANVÄNDARVÄNLIGHET PÅ WEBBEN –En analys av bensinföretagen

Webbsidor är mer än ett företags visitkort, en webbsida är för besökaren en viktig kanal för information. Internet används idag av företag, stater och kommuner världen över. Mitt ämne handlar om webbsidor och hur man kan göra dem bättre. I teoridelen klargör jag vad internet-användbarhet är. I analysdelen använder jag Eye tracking som ett verk-tyg för att analysera tre bensinföretags webbsidor. Eye tracking går ut på att man spelar in ögonrörelser då en testperson tittar på en webbsida och analyserar resultatet via bl.a. Heat-maps. Bensinföretagen vars webbsidor jag undersöker är Teboil, St1 och SEO. Syftet med analysen är att få djupare syn på hur man ser på sidorna och hur man möjlig-en kunde göra dem bättre. Via Eye trackningen svarar testpersonerna på två frågor per bensinföretag. Tid per fråga har testpersonerna en minut. Jag får också via testet svar på hur testpersonerna upplever nätsidorna i sin helhet. Testet utförs lyckat i Arcadas ut-rymmen av 20 studerande. Resultatet från min undersökning visade att man med färger, text i staplar, navigering, större text samt bättre utnyttjande av webbsidan i sin helhet kan göra sidorna användarvänligare. En uppenbar förbättring för besökaren skulle vara om man för de större bemannade bensinstationer, med bilserviceverkstäder och café-verksamhet, skulle ha egna webbsidor länkade till huvudsidan.Webpages are more than a company’s business card - a website is for the visitor an im-portant channel of information. Internet is used by companies, governments and munici-palities worldwide. My thesis deals with websites and how to make them better. In the theoretical part I clarify what internet usability is. In the analysis part I use Eye tracking as a tool to analyze three gasoline companies' websites. Through Eye tracking you can record eye movements when a test person is looking at a webpage and analyze the result by e.g. heat-maps. Gasoline companies whose websites I examine are Teboil, St1, SEO. The purpose of this analysis is to gain a deeper understanding of how you look at the pag-es and how you possibly could make them better. Via Eye tracking test persons seeks the answer to two questions per gasoline company. Time per question is one minute. I also get through the test answers on how the test persons experiencing the webpages. The test is performed successfully in Arcada’s (University of Applied Science, Helsinki) premises by 20 students. The results showed that you can with colors, text in columns, navigating tools, larger text and better use of the webpage as a whole make the pages more user friendly. An obvious improvement for the visitor would be if the larger manned gasoline stations, with car service and café, would have their own web- pages linked to the main page

Human resource management practices for self-initiated expatriates

The aim of this study is to increase the understanding of human resource management practices of self-initiated expatriates (foreign nationals hired externally), and to formulate a model of HRM of SIEs. In this study, it is found out how the HRM practices affect the SIEs, which factors affect the formation of HRM practices for SIEs and what kind of HRM practices organizations have for their SIEs. The study consists of theoretical and empirical parts. The first theoretical part deals with SIEs and their characteristics compared to assigned expatriates (AEs). The second part of the theoretical framework focuses on the changing patterns of international staffing in multinational enterprises and discusses the HRM practices for SIEs. In the end of the theoretical part, a model of HRM practices for SIEs is formulated which is used as the base for the empirical study. This study was conducted as a qualitative case study, and three different organizations from multinational enterprises were chosen to the interviews. From each organization an SIE and HR professional / manager were interviewed. The research results indicate that HRM practices for SIEs do exist and the organizations modify and adjust their basic HRM practices according to the fact that the hired employee is a foreign national. Various organizational, institutional and individual factors shape the way the HRM practices are developed and thus they depend on these factors. It was also found out that in terms of adjustment, the companies provide extensive non-financial and financial support to their SIEs.fi=Opinnäytetyö kokotekstinä PDF-muodossa.|en=Thesis fulltext in PDF format.|sv=Lärdomsprov tillgängligt som fulltext i PDF-format

Affecting corporate image through sustainable business model innovation

Abstract. The main goal of this research was to find out how a sustainable business model innovation can affect corporate image. Additional goals of this research were to also find out if consumer trust is needed for a sustainable business model innovation to affect corporate image, and if customer service linked to the innovation can affect it as well. Based on the previous research, this research proposed corporate image can be affected through corporate social responsibility actions, with a focus on mainly philanthropical actions, and customer service. The research was conducted as qualitative research, and as a case study. The chosen case company was Fiskars Group, and the sustainable business model innovation was Iittala’s Vintage Service. The data was gathered through an online questionnaire, where students at university of Oulu answered short text answers and multiple-choice questions. The responders were asked what has affected their image of Fiskars Group, if finding out about the Vintage Service had any effects on said image, and if they had used the Vintage Service. The main findings of this research are that consumer trust is needed for the sustainable business model innovation to affect corporate image, and customer service experiences linked to the innovation can affect corporate image as well. It was discovered that without consumer trust, the sustainable business model innovation either does not affect corporate image at all, or the effects are negative. The research also found that without consumer trust, the consumers are more likely to question the motives behind the sustainable business model innovation, and even suspect greenwashing. The results cannot be generalized due to the small sample of the research. However, to gain results that can be generalized, this research could be recreated with a bigger sample, or with other sustainable business model innovations. Deeper understanding of how a sustainable business model innovation can affect corporate image can also be discovered through interviews, or by having a bigger sample of answers in a questionnaire

Methods to improve debug flow for intellectual property protection

Abstract. Every company wants to protect their intellectual property and limit customer visibility of confidential information. A company may protect its proprietary information by different ways. This thesis will compare different methods that try to protect intellectual property while maintaining the software debugging capability. Working with binary libraries without debug information makes customer support very difficult. When a company is developing a new product, time to market is important. Usually, the last months are very busy resolving urgent customer issues. Especially during this period, the slow process of debugging customer issues without debug information can cause delays and increase time to market. The goal of this thesis is to compare methods that protects intellectual property by making reverse engineering more difficult. Study of the upcoming GNU Compiler Collection (GCC) features related to debug data formats, such as DWARF5, is also carried out while working with the thesis. The approaches tried were split DWARF, injecting ELF files, stripping debug data, and code obfuscation. Also optimisation and their effect on disassembly was studied. The best solution was to compile the software with debug symbols and strip them to a separate file. This way the symbol data can be loaded separately into GDB. The symbol data layout and addresses are also always correct with the solution.Virheiden etsinnän työnkulun parantaminen immateriaaliomaisuudet huomioiden. Tiivistelmä. Yritykset haluavat suojella immateriaaliomaisuuksiaan ja rajoittaa asiakkaiden näkyvyyttä tietylle tasolle asti. Tämä lopputyö vertailee eri metodeja jotka koittavat suojata immateriaaliomaisuuksia, ilman että ohjelmiston virheidenkorjattavuus kärsii. Binäärikirjastot ilman virheenkorjaustietoja vaikeuttavat asiakkaan tukemista. Uutta tuotetta kehitettäessä, markkinoille tuloaika on yritykselle tärkeää. Yleensä viimeiset kuukaudet ovat kiireisiä asiakkaan ongelmien tutkimuksien kanssa ja kyseiset ongelmat tulisi olla ratkaistuna mahdollisimman nopeasti. Tämän lopputyön tavoitteena on vertailla mahdollisia metodeja, jotka suojaavat immateriaaliomaisuutta takaisinmallinnusta vastaan. Tarkoituksena on myös tutkia tulevia GNU kääntäjä-kokoelman (GCC:n) ominaisuuksia liittyen virheenkorjaustietoformaatteihin, kuten DWARF5. Ongelman ratkaisuun koitettiin pilkottuja virheenkorjaustietoja, ELFtiedoston injektointia, virheenkorjaustiedon riisumista ohjelmistosta ja koodin obfuskointia. Myös optimoinnin vaikutusta konekielestä takaisinmallinnettuun Assembly-muotoon tutkittiin. Paras ratkaisu oli kääntää ohjelmisto virheenkorjaustiedolla ja riisua ne omaan erilliseen tiedostoon. Näin ohjelmiston symbolitieto pystytään latamaan erikseen virheenjäljittemänä käytettyyn GNU Debuggeriin (GDB:hen). Näin symbolitietojen rakenne ja osoitteet ovat myös aina paikkansapitävät

Heating system decision:a study based on newly built detached houses in Finland

Abstract. This study examines new detached house owners’ residential heating system choice determinants in Finland. The randomly drawn survey-based research includes three separate interrelated empirical models. An overview of Finnish household space heating is included. Residential space heating system is a long-term investment, and the sector forms a significant part of energy consumption. The theoretical framework builds on the random utility theory and discrete choice models. With binomial logit formulations, we study the factors that impact the ground source heat pump adoption and the determinants to acquire innovative supplementary heating systems. Study of the primary heating system choice determinants among five distinct alternative categories is done with a multinomial logit model. The dependent variables are actual heating system choices. The survey design gives us the chance to observe stated preferences as explanatory variables. We discover substantial heterogeneity in consumer preferences. There are statistically significant explanatory variables related to socio-demographics, house-type, the geographical area and heating system specific factors. Variable cost is the largest driver for ground source heat pump selection. Other issues that have a considerable impact are system comfort, larger home, self-sufficiency requirement and expert opinions. Innovative supplementary heating system as a part of hybrid generation can create significant efficiency gains. The determinants to acquire such system suggest the desire to remain interconnected with the grid, whereas investment cost can hinder the adoption. Energy performance certificate seems to drive the air-source heat pump choice. It appears that impacting variable price expectations could alter heating system choice. The multinomial analysis implies to cost and comfort considerations having a bigger impact than environmental attitudes. Post-decision satisfaction comments suggest a considerable need for system function check-up including the settings, especially for the heat pumps

Speed and Accuracy of Gaze Gestures

We conducted an experiment where participants carried out six gaze gesture tasks. The gaze paths were analyzed to find out the speed and accuracy of the gaze gestures. As a result, the gaze gestures took more time than we anticipated and only the very fastest participants got close to what was expected. There was not much difference in performance times between small and large gaze gestures, because the participants reached significantly faster speed when making large gestures than small gestures. Curved shapes were found difficult to follow and time-consuming when followed properly. In general, the accuracy in following shapes was sometimes very poor. We believe that to improve the speed and accuracy of gaze gestures, proper feedback must be used more than in our experiment

Monte Carlo Simulations of the Transition Radiation Detector of the AMS-02 Experiment

The Transition Radiation Detector of the AMS-02 experiment on the International Space Station is used for the separation of cosmic-ray positrons and electrons from protons and anti-protons, and for the identification of nuclei up to carbon (Z<=6). We present the Geant4 simulation that is used to describe the ionization and transition radiation processes and compare its results to flight data from AMS-02. After applying empirical corrections to the simulated data, the particle energy deposition and likelihood distributions in the TRD are described with high accuracy.Comment: 7 pages, 9 figures.
