Franchisingyrittäjä–valmennus ja franchisingin tila Suomessa

Tutkielman tavoitteena oli selvittää: - Miten franchisingvalmennus eroaa klassisesta yrittäjäkoulutuksesta? - Mitä mieltä franchisingyrittäjä-valmennuksen läpikäyneet ovat valmennuksesta? - Mikä on franchisingin tila Suomessa? Yrittäjyyttä tarkasteltaessa huomiota kiinnitettiin käsitteen määrittämiseen yrittäjätypologioiden, motivaatioteorioiden ja toimintaympäristön kautta. Tutkielmassa selvitettiin myös yrittäjäksi ryhtymiseen vaikuttavia tekijöitä ja Suomen yrittäjyysaktiivisuuden tasoa. Franchisingin osalta määriteltiin eri toimintamuodot ja keskityttiin Business Format Franchising-toimintamalliin. Työssä selvitettiin myös franchisingyrittäjyyden eroja klassiseen yrittäjyyteen ja tarkasteltiin franchisingin tilaa Suomessa. Koulutuksen osalta keskityttiin tarkastelemaan aikuiskoulutusta ja vielä tarkemmin työvoimapoliittista yrittäjäkoulutusta sekä koulutuksen arviointia. Työssä tarkasteltiin myös franchisingyrittäjä-valmennusta ja sen tavoitteet käytiin myös läpi. Empiirinen tutkimus koostui 118:ta franchisingyrittäjä-valmennukseen vuosina 1998–2000 osallistuneesta henkilöstä. Tutkimus suoritettiin postikyselynä. Tutkimusaineistoa analysoitiin SPSS for Windows-tietojenkäsittelyohjelmalla ja tutkimusjoukon kuvailuun käytettiin frekvenssejä, prosenttilukuja ja ristiintaulukointia. Franchisingvalmennus ja klassinen yrittäjäkoulutus erosivat siinä vaiheessa, kun tarkasteltiin franchisingantajan ja – ottajan näkökulmaa. Franchisingyrittäjä-valmennuksessa käsiteltiin hyvinkin tarkasti sekä franchisingantajan, että – ottajan roolit, velvollisuudet ja oikeudet. Franchisingyrittäjä-valmennuksessa ei myöskään käsitelty lainkaan tuotekehitystä ja lanseerausta. Franchisingyrittäjä-valmennus oli suurimmalle osalle koulutuksen läpäisseistä positiivinen kokemus. Yhdeksän kymmenestä oli myös valmiita suosittelemaan valmennusta franchisingyrittäjyydestä kiinnostuneille henkilöille. Suomessa franchisingin kehitys on siirtymässä suvantovaiheesta uuden kasvun vaiheeseen. Uusia franchisingketjuja perustetaan ja vanhat ketjut lisäävät toimipaikkojensa määrää. Jatkossa voidaan odottaa naisyrittäjien määrän lisääntyvän, sillä uusimmat Suomeen perustetut ketjut ovat terveys- ja hoiva-alalla, jotka ovat perinteisesti naisvaltaisia aloja.

Wavefront reconstruction by adding modulation capabilities of two liquid crystal devices

We analyze the behavior of complex information in the Fresnel domain, taking into account the limited capability to display complex values of liquid crystal devices when they are used as holographic displays. To do this analysis we study the reconstruction of Fresnel holograms at several distances using the different parts of the complex distribution. We also use the information adjusted with a method that combines two configurations of the devices in an adding architecture. The results of the error analysis show different behavior for the reconstructions when using the different methods. Simulated and experimental results are presented.

Comparative effectiveness of gemcitabine plus cisplatin versus methotrexate, vinblastine, doxorubicin, plus cisplatin as neoadjuvant therapy for muscle-invasive bladder cancer.

BACKGROUND: Gemcitabine plus cisplatin (GC) has been adopted as a neoadjuvant regimen for muscle-invasive bladder cancer despite the lack of Level I evidence in this setting. METHODS: Data were collected using an electronic data-capture platform from 28 international centers. Eligible patients had clinical T-classification 2 (cT2) through cT4aN0M0 urothelial cancer of the bladder and received neoadjuvant GC or methotrexate, vinblastine, doxorubicin, plus cisplatin (MVAC) before undergoing cystectomy. Logistic regression was used to compute propensity scores as the predicted probabilities of patients being assigned to MVAC versus GC given their baseline characteristics. These propensity scores were then included in a new logistic regression model to estimate an adjusted odds ratio comparing the odds of attaining a pathologic complete response (pCR) between patients who received MVAC and those who received GC. RESULTS: In total, 212 patients (146 patients in the GC cohort and 66 patients in the MVAC cohort) met criteria for inclusion in the analysis. The majority of patients in the MVAC cohort (77%) received dose-dense MVAC. The median age of patients was 63 years, they were predominantly men (74%), and they received a median of 3 cycles of neoadjuvant chemotherapy. The pCR rate was 29% in the MVAC cohort and 31% in the GC cohort. There was no significant difference in the pCR rate when adjusted for propensity scores between the 2 regimens (odds ratio, 0.91; 95% confidence interval, 0.48-1.72; P = .77). In an exploratory analysis evaluating survival, the hazard ratio comparing hazard rates for MVAC versus GC adjusted for propensity scores was not statistically significant (hazard ratio, 0.78; 95% confidence interval, 0.40-1.54; P = .48). CONCLUSIONS: Patients who received neoadjuvant GC and MVAC achieved comparable pCR rates in the current analysis, providing evidence to support what has become routine practice.

MgO/Ag(001) interface structure and STM images from first principles

The interface of MgO/Ag(001) has been studied with density functional theory applied to slabs. We have found that regular MgO films show a small adhesion to the silver substrate, the binding can be increased in off-stoichiometric regimes, either by the presence of O vacancies at the oxide film or by a small excess of O atoms at the interface between the ceramic to the metal. By means of theoretical methods, the scanning tunneling microscopy signatures of these films is also analyzed in some detail. For defect free deposits containing 1 or 2 ML and at low voltages, tunnelling takes place from the surface Ag substrate, and at large positive voltages Mg atoms are imaged. If defects, oxygen vacancies, are present on the surface of the oxide they introduce much easier channels for tunnelling resulting in big protrusions and controlling the shape of the image, the extra O stored at the interface can also be detected for very thin films.

Toiminnan kehittäminen ohutlevykonepajassa

Yritysmaailma elää jatkuvassa muutoksessa. Yrityksen kehittäminen on yrityksen menestymisen kannalta välttämätöntä. Mikäli yritystä ei aktiivisesti kehitetä, kilpailijat valtaavat yrityksen elintilan ja yritys taantuu ja lopulta yrityksen toiminta lakkaa. Tämän työn tarkoituksena oli kehittää Compusteel Oy:n toimintaa ja edistää yhtiön kilpailukykyä lähitulevaisuudessa. Compusteel Oy on luonteeltaan alihankkija / komponenttitoimittaja. Tällaisen yrityksen tärkein kilpailutekijä on tehokas tuotanto. Tässä työssä keskityttiin tutkimaan erityisesti keinoja, millä tuotantoa voidaan tehostaa. Useissa työn lähteenä käytetyissä tutkimuksissa on havaittu tiedon välittämisen merkitys nykyaikaisen yrityksen kilpailutekijänä. Tyypillisimmillään toiminnan virheet johtuvat tiedon puutteellisesta välittämisestä sekä tiedon käytettävyyden heikosta tasosta tarvetilanteessa. Tutkimus toteutettiin kirjallisuuden ja muun lähdeaineiston kuten koulutusten avulla. Tutkimuksessa paneuduttiin erityisesti erilaisten tuotannonohjausmenetelmien kartoittamiseen sekä niiden hyödyntämiseen yrityksen toiminnassa. Työn tuloksena syntyi Compusteel Oy:öön uusi toimintamalli tiettyihin yrityksen ydin prosesseihin. Erityisen tärkeänä nähtiin uuden ajattelumallin omaksuminen tuotannonohjaushenkilöstössä. Uutta ajattelumallia voidaan tulevaisuudessa soveltaa useissa yrityksen kehittämishankkeissa. Lisäksi työn tuloksena käyttöönotettiin uusi toiminnanohjausjärjestelmä, joka tukee uutta toimintamallia.

The Coordinated Radio and Infrared Survey for High-mass Star Formation. II. Source Catalog

The CORNISH project is the highest resolution radio continuum survey of the Galactic plane to date. It is the 5 GHz radio continuum part of a series of multi-wavelength surveys that focus on the northern GLIMPSE region (10° < l < 65°), observed by the Spitzer satellite in the mid-infrared. Observations with the Very Large Array in B and BnA configurations have yielded a 1.''5 resolution Stokes I map with a root mean square noise level better than 0.4 mJy beam 1. Here we describe the data-processing methods and data characteristics, and present a new, uniform catalog of compact radio emission. This includes an implementation of automatic deconvolution that provides much more reliable imaging than standard CLEANing. A rigorous investigation of the noise characteristics and reliability of source detection has been carried out. We show that the survey is optimized to detect emission on size scales up to 14'' and for unresolved sources the catalog is more than 90% complete at a flux density of 3.9 mJy. We have detected 3062 sources above a 7σ detection limit and present their ensemble properties. The catalog is highly reliable away from regions containing poorly sampled extended emission, which comprise less than 2% of the survey area. Imaging problems have been mitigated by down-weighting the shortest spacings and potential artifacts flagged via a rigorous manual inspection with reference to the Spitzer infrared data. We present images of the most common source types found: H II regions, planetary nebulae, and radio galaxies. The CORNISH data and catalog are available online at http://cornish.leeds.ac.uk.

Using computational fluid dynamics to predict head losses in the auxiliary elements of a microirrigation sand filter

It is often assumed that total head losses in a sand filter are solely due to the filtration media and that there are analytical solutions, such as the Ergun equation, to compute them. However, total head losses are also due to auxiliary elements (inlet and outlet pipes and filter nozzles), which produce undesirable head losses because they increase energy requirements without contributing to the filtration process. In this study, ANSYS Fluent version 6.3, a commercial computational fluid dynamics (CFD) software program, was used to compute head losses in different parts of a sand filter. Six different numerical filter models of varying complexities were used to understand the hydraulic behavior of the several filter elements and their importance in total head losses. The simulation results show that 84.6% of these were caused by the sand bed and 15.4% were due to auxiliary elements (4.4% in the outlet and inlet pipes, and 11.0% in the perforated plate and nozzles). Simulation results with different models show the important role of the nozzles in the hydraulic behavior of the sand filter. The relationship between the passing area through the nozzles and the passing area through the perforated plate is an important design parameter for the reduction of total head losses. A reduced relationship caused by nozzle clogging would disproportionately increase the total head losses in the sand filter

La integración de Internet en la educación escolar española : situación actual y perspectivas de futuro

The main objectives and findings of this first research report are presented in this chapter."The Implementation of the Internet in the Spanish Education System: State of Affairs and Future Prospects" is a large-scale research project that seeks to obtain relevant data about the introduction and dissemination of Information and Communication Technology, particularly the internet, in the practical and organizational general procedures of the Spanish schools and high schools. The project articulates the processes of ICT implementation on the primary and secondary education levels embracing a holistic approach, propped up by an empirical and analytical research methodology. Thus, our survey does not intend to detect which is the impact of ICT on school activities but how all the agents involved in the school community incorporate ICT and what use they make of it. We are especially interested in identifying the teachers' pedagogical and professional uses of ICT, how students use it in their activities and to what extent it contributes in reinforcing teamwork and participation proceedings in the institutions, as well as the relations between the latter and their context. It is also of our interest to know the factors that exert the strongest influence on the way teachers, head teachers and students make use of ICT. Finally, we intend to identify the ways ICT may contribute to the improvementof educational practices.

A Computer program for estimating population size by the removal method

A BASIC computer program (REMOVAL) was developed to compute in a VAXNMS environment all the calculations of the removal method for population size estimation (catch-effort method for closed populations with constant sampling effort). The program follows the maximum likelihood methodology,checks the failure conditions, applies the appropriate formula, and displays the estimates of population size and catchability, with their standard deviations and coefficients of variation, and two goodness-of-fit statistics with their significance levels. Data of removal experiments for the cyprinodontid fish Aphanius iberus in the Alt Emporda wetlands are used to exemplify the use of the program

Interfície gràfica per a la valoració d'operadors de preprocessat d'imatge en imatges d'ultrasò

El càncer de mama és una de les causes de més mortalitat entreles dones dels països desenvolupats. És tractat d'una maneramés eficient quan es fa una detecció precoç, on les tècniques d'imatge són molt importants. Una de les tècniques d'imatge més utilitzades després dels raigs-X són els ultrasons. A l'hora de fer un processat d'imatges d'ultrasò, els experts en aquest camp es troben amb una sèrie de limitacions en el moment d'utilitzar uns filtrats per les imatges, quan es fa ús de determinades eines. Una d'aquestes limitacions consisteix en la falta d'interactivitat que aquestes ens ofereixen. Per tal de solventar aquestes limitacions, s'ha desenvolupat una eina interactiva que permet explorar el mapa de paràmetres visualitzant el resultat del filtrat en temps real, d'una manera dinàmica i intuïtiva. Aquesta eina s'ha desenvolupat dins l'entorn de visualització d'imatge mèdica MeVisLab. El MeVisLab és un entorn molt potent i modular pel desenvolupament d'algorismes de processat d'imatges, visualització i mètodes d'interacció, especialment enfocats a la imatge mèdica. A més del processament bàsic d'imatges i de mòduls de visualització, inclou algorismes avançats de segmentació, registre i moltes análisis morfològiques i funcionals de les imatges.S'ha dut a terme un experiment amb quatre experts que, utilitzantl'eina desenvolupada, han escollit els paràmetres que creien adientsper al filtrat d'una sèrie d'imatges d'ultrasò. En aquest experiments'han utilitzat uns filtres que l'entorn MeVisLab ja té implementats:el Bilateral Filter, l'Anisotropic Difusion i una combinació d'un filtrede Mediana i un de Mitjana.Amb l'experiment realitzat, s'ha fet un estudi dels paràmetres capturats i s'han proposat una sèrie d'estimadors que seran favorables en la majoria dels casos per dur a terme el preprocessat d'imatges d'ultrasò
