BPMN process views construction

Process view technology is catching more attentions in modern business process management, as it enables the customisation of business process representation. This capability helps improve the privacy protection, authority control, flexible display, etc., in business process modelling. One of approaches to generate process views is to allow users to construct an aggregate on their underlying processes. However, most aggregation approaches stick to a strong assumption that business processes are always well-structured, which is over strict to BPMN. Aiming to build process views for non-well-structured BPMN processes, this paper investigates the characteristics of BPMN structures, tasks, events, gateways, etc., and proposes a formal process view aggregation approach to facilitate BPMN process view creation. A set of consistency rules and construction rules are defined to regulate the aggregation and guarantee the order preservation, structural and behaviour correctness and a novel aggregation technique, called EP-Fragment, is developed to tackle non-well-structured BPMN processes.

Josh lovegrove: Infinite

Research background: Infinite by Josh Lovegrove is an extended play album co-produced in collaboration with ARIA-nominated artist Mark Sholtez. The album consists of original songs written by Lovegrove, and songs co-written by Lovegrove, Carfoot and Sholtez. The scholarly context of the project is informed by studies of songwriting and ambiguity by Negus and Astor, new approaches to the study of record production associated with Zagorski-Thomas, and studies of creative labour by Hesmondhalgh and Baker. The project focused on the dynamics of musical performance and production in the recording studio, investigating the interface between the creative tasks of songwriting, production and performance in the recording of popular music. The project asked, in what ways do collaborative songwriting and production processes overlap, how has the nature of creative labour changed as a result of new forms of digital recording technology, and how can these aspects inform developments in the learning and teaching of popular music? Research contribution: The project has demonstrated the nuanced ways that the practices of record production have changed in the face of technological developments, and how this has impacted upon the specific forms and divisions of creative labour. Research significance: The project resulted in a well-reviewed album release that has further established Lovegrove’s reputation as a performer and songwriter. The creative work underpins ongoing research into the nature of popular music production, in particular how the nature of collaborative songwriting can inform innovation in the learning and teaching of popular music.

Ufologia ja ufokokemukset uskonnollisina ilmiönä : Teoreettinen tutkimus

The main question of my doctoral thesis is whether ufology and UFO experiences are or can be explained as religious phenomena. My research is theoretical in the sense that I combine and systematise cultural scientific knowledge concerning the religiosity of ufology and UFO experiences and complete this theoretical effort with empirical subject matter. The research material for my study consists of theoretical literature and empirical texts written by ufologists and those who have had UFO experiences. I defined the material in a way that it became full and extensive with regard to ufology, stories about UFO experiences and the cultural scientific literature concerning them. In addition, I present a source criticism for the literature because it is in part informal. The method is analysing and synthesising the material in the context of spiral of hermeneutic inferential process. Definitions of religion, ufology and UFO experience, developed by myself, serve as guide lines for the process. The conclusions of my research are as follows. For the most part, ufology and UFO experiences belong to the category of religion and only a fraction of these instances can be explained as something else, for example psychiatric phenomena. From the religious viewpoint I explain ufology and UFO experiences on four different but interlinked levels: historical, comparative, sociological and psychological. Historically ufology and UFO experiences include esoteristic, Christian and folk religious elements. In addition UFO experiences have significant similarities with folk religious stories and shamanistic experiences. From the perspective of the sociology, of religion ufology and UFO experiences can be analysed as products of our scientific and technological Western culture. Social crisis and social psychological group mechanisms affect the appearance of ufological ideas and UFO experiences. Psychologically, in the background of religious UFO experiences there can be found several factors, such as wishful thinking. Concerning UFO sightings these are misinterpretations of certain ordinary and some rare or exotic natural and technical phenomena. Intense UFO experiences, such as UFO abductions, are stimulated for the most part by hallucinations, sleep paralysis disorders, lively fantasies (in case of fantasy prone personalities) and false memories. In group cases social pressure, small group delusion and the guilt of exposing the true nature of a story come into play. A UFO experience can be traumatising because of certain inferential mechanisms and cognitive dissonance involved in the process of conversion as a UFO experiencer. UFO religiosity is a cross cultural, widespread and a significant field of phenomena, which can offer insight about religious developments in the future. However, UFO religiosity has not been studied extensively. This research is one effort to address this lack of documentation. The motivation behind my thesis was to make ufology and UFO experiences more understandable.

Deep inelastic electroproduction structure functions for polarized and unpolarized proton targets

Following Ioffe's method of QCD sum rules the structure functions F2(x) for deep inelastic ep and en scattering are calculated. Valence u-quark and d-quark distributions are obtained in the range 0.1 less, approximate x <0.4 and compared with data. In the case of polarized targets the structure function g1(x) and the asymmetry Image Full-size image are calculated. The latter is in satisfactory agreement in sign and magnitude with experiments for x in the range 0.1< x < 0.4.

Suomi kasvitieteen kieleksi : Elias Lönnrot termistön kehittäjänä

The development of botanical Finnish: Elias Lönnrot as the creator of new terminology In the 19th century the Finnish language was intentionally developed to meet the demands of civilised society and Finnish-language science. The development of the language involved several people from different fields of science. This study examines this enormous project in the field of botany. By which methods were scientific terms formed, and for which reasons were those terms used? Why has a certain word been chosen to represent a particular concept? The material of this study is the terminology of plant morphology in Finnish that Elias Lönnrot developed in the middle of the 19th century. The terms of plant morphology denote and describe the parts of the plant and the relationships between those parts. For instance, the terms emi pistill , hede stamen , terälehti petal and verholehti sepal , which are nowadays familiar in the general language, were used for the first time in Lönnrot s texts. The study integrates the methods of lexicology and terminology. In lexicology, the word and its various meanings serve as the focus, whereas the theory of terminology focuses on the concept and concept systems. A new, consciously developed terminology can be understood through the old, familiar vocabulary and structures as well as through the new, logical term system. Lönnrot s botanical terminology can be divided into three groups depending on their origin: 1) 19% of all terms have been accepted from the existing vocabulary and used in their original meanings, 2) 11% of all terms have been chosen from the existing vocabulary and used in the new, specific botanical meanings, and 3) 70% of all terms have been created on the basis of the existing vocabulary and used in the new, specific botanical meanings. Therefore, the study reveals that domestic materials primarily morphosemantic neologisms form the Finnish terminology of plant morphology. Characteristic of Lönnrot s botanical terms is the utilisation of the vocabulary of various Finnish dialects and particular repeating elements. Repeating elements include, for example, the prefixes that come from botanical Latin or Swedish as well as the particular Finnish derivation types. Such structures form term systems that reflect scientific concept systems. Two thirds of the created new words are formed loosely or precisely according to either Latin or Swedish terms; one third is formed completely differently from its equivalents in the foreign languages. Approximately half of the chosen terms are formed differently from the Latin and Swedish terms. It is worth noting that many loan translations use rare vocabulary from Finnish dialects as equivalents to foreign parts of terms. Lönnrot aimed to inspire scientific terminology with Finland s own language, thus making scientific text accessible to the Finnish agricultural population.

Low temperature electrical transport properties of carbon matrix containing iron nanoparticles

We present a comparative study of the low temperature electrical transport properties of the carbon matrix containing iron nanoparticles and the films. The conductivity of the nanoparticles located just below the metal-insulator transition exhibits metallic behavior with a logarithmic temperature dependence over a large temperature interval. The zero-field conductivity and the negative magnetoresistance, showing a characteristic upturn at liquid helium temperature, are consistently explained by incorporating the Kondo relation and the two dimensional electron-electron interaction. The films, in contrast, exhibit a crossover of the conductivity from power-law dependence at high temperatures to an activated hopping law dependence in the low temperature region. The transition is attributed to changes in the energy dependence of the density of states near the Fermi level. The observed magnetoresistance is discussed in terms of quantum interference effect on a three-dimensional variable range hopping mechanism.

"Wicca=..." : Sosiaalisen identiteetin vaikutus wiccan määrittelyyn Suomiwicca-keskustelulistalla

Kysymys wiccan määrittelystä nousi ajankohtaiseksi vuosituhannen vaihteessa, kun joukko wiccoja päätti hakea uskonnolleen virallisen yhdyskunnan asemaa. Yritys ei onnistunut, sillä opetusministeriö piti wiccaa liian hajanaisena, eikä katsonut sen täyttävän laissa määriteltyjä uskonnon tunnusmerkkejä. Tutkielman tarkoitus on paneutua nimenomaan virallistamis-prosessin puitteissa käytyyn määrittelykeskusteluun diskurssianalyysin tarjoamin keinoin. Aineistona käytän projektin avuksi perustettua Suomiwicca-keskustelulistaa. Keskeisiä kysymyksiä ovat mm. miksi määrittely loppujen lopuksi on niin vaikeaa, ja miten siihen liittyviä ongelmia on pyritty ratkaisemaan. Samalla kiinnitän huomiota yleiseen uskonnon määrittelyyn uskonnonvapauslain näkökulmasta sekä länsimaissa tapahtuvaan uskonnollisuuden individualistumiseen. Määrittelyvaikeuksien juuret nousevat wiccan historiasta ja avoimen lähteen uskonnolle tyypillisistä piirteistä. Aineistossani lisäväriä keskusteluun tuovat lainsäädännön vaatimukset sekä oman sosiaalisen identiteetin varjeleminen. Teoreettisena viitekehyksenä toimiikin H. Tajfelin ja J. C. Turnerin sosiaalisen identiteetin teoria. Määrittelyyn kiinteässä yhteydessä olevan kategorisoinnin kognitiiviset periaatteet on niin ikään huomioitu. Analyysi paljastaa, että määrittely koetaan vaikeaksi, koska wicca on luonteeltaan epä-dogmaattinen, yksilön autonomiaa korostava mysteeriuskonto. Tällaista uskontoa ei kukaan voi eikä kenenkään pitäisi määritellä, vaan wiccalaisuus perustuu itsemäärittelyyn. Silti tunnustetaan, ettei kaikki wiccaksi nimetty ole wiccaa, ja käytännössä itsemäärittelyn rinnalle astuu muita tekijöitä. Eroa wiccan ja ei-wiccan välille yritetään tehdä mm. erottautumalla sosiaalista identiteettiä heikentävistä liikkeistä (esim. satanismi, new age), jotka ulkopuoliset usein yhdistävät wiccaan. Erotteluja tehdään myös wiccan sisällä. Kritiikin kohteeksi joutuvat sekä yksittäiset henkilöt että eklektinen wicca-suuntaus kokonaisuutena. Oikeudesta wicca-nimitykseen ja siihen liittyvään sosiaaliseen identiteettiin pidetään kuitenkin lujasti kiinni, ja vihjailuja epäaitoudesta pidetään loukkaavina. Käytännössä itsemäärittely osoittatuu siis toimimattomaksi ja liian löyhäksi strategiaksi, vaikka onkin sopusoinnussa wiccan ideologian kanssa. Itseidentifikaatio on toki oleellinen osa wiccana olemista, mutta sen lisäksi on oltava uskottava, ja tultava muiden wiccojen hyväksymäksi perheyhtäläisyyden perusteella. Perheyhtäläisyyspiirteiden sijasta listalla keskitytään kuitenkin wiccaa monoteettisesti määrittävän piirteen etsimiseen. Tällaiseksi ehdotetaan mm. redeä, jumalkäsitystä sekä luontosuhdetta, mutta tulkinnallisten erimieli-syyksien vuoksi yhtäkään niistä ei kelpuuteta. Sen sijaan selkeyttä wiccakenttään näyttää tuovan taksonomisten jaotteluiden tekeminen ja wicca-suuntausten erojen korostaminen. Näin kaikki wiccaksi nimittäytyvät tunnustetaan wiccoiksi, mutta kenenkään sosiaalinen identiteetti ei silti heikkene. Strategia vaikuttaa lupaavalta, mutta sen tasa-arvoinen toteutuminen vaatii vielä hiomista ja uudenlaisten jaottelujen vakiinnuttamista. Tämä kuitenkin todistaa, ettei tyydyttävän määritelmän löytyminen ole täysin mahdotonta, kunhan kaikki wicca-ryhmittymät huomioidaan eikä keneltäkään yritetä väkisin riistää sosiaalista identiteettiä.

Essays on Misplanning Wealth and Health: A Behavioural Approach

The dissertation consists of three essays on misplanning wealth and health accumulation. The conventional economics assumes that individual's intertemporal preferences are exponential (exponential preferences, EP). Recent findings in behavioural economics have shown that, actually, people do discount near future relatively heavier than distant future. This implies hyperbolic intertemporal preferences (HP). Essays I and II concentrate especially on the effects of a delayed completion of tasks, a feature of behaviour that HP enables. Essay III uses current Finnish data to analyse the evolvement of the quality adjusted life years (QALYs) and inconsistencies in measuring that. Essay I studies the existence effects of a lucrative retirement savings program (SP) on the retirement savings of different individual types having HP. If the individual does not know that he will have HP also in the future, i.e. he is the naïve, for certain conditions, he delays the enrolment on SP until he abandons it. Very interesting finding is that the naïve retires then poorer in the presence than in the absence of SP. For the same conditions, the individual who knows that he will have HP also in the future, i.e. he is the sophisticated, gains from the existence of SP, and retires with greater retirement savings in the presence than in the absence of SP. Finally, capabilities to learn from past behaviour and about intertemporal preferences improve possibilities to gain from the existence but an adequate time to learn must be then guaranteed. Essay II studies delayed doctor's visits, theirs effects on the costs of a public health care system and government's attempts to control patient behaviour and fund the system. The controlling devices are a consultation fee and a deductible for that. The deductible is effective only for a patient whose diagnosis reveals a disease that would not get cured without the doctor's visit. The naives delay their visits the longest while EP-patients are the quickest visitors. To control the naives, the government should implement a low fee and a high deductible, while for the sophisticates the opposite is true. Finally, if all the types exist in an economy then using an incorrect conventional assumption that all individuals have EP leads to worse situation and requires higher tax rates than assuming incorrectly but unconventionally that only the naives exists. Essay III studies the development of QALYs in Finland 1995/96-2004. The essay concentrates on developing a consistent measure, i.e. independent of discounting, for measuring the age and gender specific QALY-changes and their incidences. For the given time interval, use of a relative change out of an attainable change seems to be almost intact to discounting and reveals that the greatest gains are for older age groups.

A curve shortening flow rule for closed embedded plane curves with a prescribed rate of change in enclosed area

Motivated by a problem from fluid mechanics, we consider a generalization of the standard curve shortening flow problem for a closed embedded plane curve such that the area enclosed by the curve is forced to decrease at a prescribed rate. Using formal asymptotic and numerical techniques, we derive possible extinction shapes as the curve contracts to a point, dependent on the rate of decreasing area; we find there is a wider class of extinction shapes than for standard curve shortening, for which initially simple closed curves are always asymptotically circular. We also provide numerical evidence that self-intersection is possible for non-convex initial conditions, distinguishing between pinch-off and coalescence of the curve interior.

RF Sputtered Er2O3 Thin Films as High-k Gate Dielectrics for Germanium MOS Devices

We report the material and electrical properties of Erbium Oxide (Er2O3) thin films grown on n-Ge (100) by RF sputtering. The properties of the films are correlated with the processing conditions. The structural characterization reveals that the films annealed at 550 degrees C, has densified as compared to the as-grown ones. Fixed oxide charges and interface charges, both of the order of 10(13)/cm(2) is observed.

Microbially induced flotation of galena and quartz from pyrite

Selective separation of pyrite from galena and quartz was achieved through microbiologically induced flotation in presence of Bacillus subtilis. B. subtilis functions as a depressant for pyrite while it promotes the flotation of galena and quartz. Bacterial extracellular protein (EP) was isolated and the protein profile of bacterial cells grown in presence and absence of minerals established.

Quasi-periodic, global oscillations in sea level pressure on intraseasonal timescales

The sea level pressure (SLP) variability in 30-60 day intraseasonal timescales is investigated using 25 years of reanalysis data addressing two issues. The first concerns the non-zero zonal mean component of SLP near the equator and its meridional connections, and the second concerns the fast eastward propagation (EP) speed of SLP compared to that of zonal wind. It is shown that the entire globe resonates with high amplitude wave activity during some periods which may last for few to several months, followed by lull periods of varying duration. SLP variations in the tropical belt are highly coherent from 25A degrees S to 25A degrees N, uncorrelated with variations in mid latitudes and again significantly correlated but with opposite phase around 60A degrees S and 65A degrees N. Near the equator (8A degrees S-8A degrees N), the zonal mean contributes significantly to the total variance in SLP, and after its removal, SLP shows a dominant zonal wavenumber one structure having a periodicity of 40 days and EP speeds comparable to that of zonal winds in the Indian Ocean. SLP from many of the atmospheric and coupled general circulation models show similar behaviour in the meridional direction although their propagation characteristics in the tropical belt differ widely.

Size-dependent magnetic properties of iron carbide nanoparticles embedded in a carbon matrix

Here we report on the magnetic properties of iron carbide nanoparticles embedded in a carbon matrix. Granular distributions of nanoparticles in an inert matrix, of potential use in various applications, were prepared by pyrolysis of organic precursors using the thermally assisted chemical vapour deposition method. By varying the precursor concentration and preparation temperature, compositions with varying iron concentration and nanoparticle sizes were made. Powder x-ray diffraction, transmission electron microscopy and Mossbauer spectroscopy studies revealed the nanocrystalline iron carbide (Fe3C) presence in the partially graphitized matrix. The dependence of the magnetic properties on the particle size and temperature (10 K < T < 300 K) were studied using superconducting quantum interference device magnetometry. Based on the affect of surrounding carbon spins, the observed magnetic behaviour of the nanoparticle compositions, such as the temperature dependence of magnetization and coercivity, can be explained.

Siirtonaisena Singaporessa : Ulkomaantyökomennuksille mukaan muuttaneet suomalaisnaiset kertovat kokemuksistaan

The objective of this qualitative study is to reveal the discursive reality of Finnish women, who have chosen to follow their husbands to expatriate assignments. The research material includes interviews of seventeen (17) Finnish housewives who lived in Singapore in 1999. The primary theoretical framework of the study is a social-constructive view, in which the reality is seen to have been constructed through meanings that create and maintain cultural practices, social roles and institutions. Gender is interpreted as produced socially, politically and in language. Human beings in the study exist as cultural and social beings with sex. An underlying assumption of the analysis is that the women in the study do not recognize their experience from their position that has been located to the prompt box in a play of expatriate assignment a role that is offered to them by the business sciences. Referring to Somers (1994) these women suffer of narrative silence as they lack public narratives that correspond to their circumstances. According to Williams (1983), an experience is an evidence of conditions. Therefore, the experiences of the women, who have followed their husbands to expatriate assignments, include information of their conditions. The analysis of the interview material has been performed in two phases: First, the women's experiences are identified from the research material. Thereafter, by means of discourse analysis the experiences are revealed analytically. This revealing process can also be regarded as an articulation of a counter-narrative. The research results can be found from three such discursive interpretations that are offered to the women and from eight such discursive interpretations that can be drawn from the women's own experiences. One of the discursive interpretations, which came out from the women's own experiences, is named as cultural dysphasia. In the study, cultural dysphasia is defined as a condition, in which the women have a difficulty in making their lived reality understood by others outside the sphere of their situation. Finnish women do not only lack public narrative, but the absence of a housewife-culture in Finland prevents them from any public narrative that would have a positive tone. To avoid dependence on the housewife concept, a woman's decision to follow her husband to an expatriate assignment is interpreted as a demonstration of solidarity to the relationship. In this connection, these Finnish women are re-named as 'siirtonainen' (Finnish, literally 'transfer woman'). This is the first scientific study to make visible the lived reality of Finnish women who have followed their husbands to expatriate assignments. The study will help the women in similar circumstances to find their marks among the current narratives. By reducing dichotomy between housewives and career women, which is damaging to women, and by creating the concept of 'siirtonainen' it will be possible to expand the cultural space of Finnish women. Finally, the study argues that a Finnish career woman, grown together with the imperative of self-support, has been lifted up as one symbol of modern Finland. Key words: expatriate research, experience, public narrative, narrative silence, cultural dysphasia, siirtonainen - transfer woman

Paluu paratiisiin : Polkuja hyvän ja pahan tuolle puolen Martti Lutherin ja Friedrich Nietzschen perinteissä

Tutkimukseni tarkoitus on paikallistaa polkuja hyvän ja pahan tuolle puolen. Tutkimukseni termit hyvä ja paha määrittyvät moraalisesti. Täten tutkimusaiheeni on ihmisen ja moraalin välinen suhde. Tutkin ihmisen moraalista olotilaa, siinä tapahtuvaa muutosta ja tämän muutoksen ehtoja. Tutkimuksellani on kaksi pääkysymystä: kuinka on mahdollista päästä hyvän ja pahan tuolle puolen ja miksi meidän tulisi siirtyä hyvän ja pahan tuolle puolen. Polut hyvän ja pahan tuolle puolen vievät myös etiikan tuolle puolen. Tutkimukseni pyrkii selvittämään mitä vikaa etiikassa on ja kuinka on mahdollista perustella toimintaa ilman etiikkaa. Tutkimukseni metodi on systemaattinen analyysi. Johdanto-osassa käsittelen yleisesti moraalia, sen vaikutuspiiriä ja niitä syitä, joiden vuoksi se täytyy hylätä. Tarkastelen myös etiikkaa ja selvitän sitä laajempaa kontekstia mihin se liittyy. Ensimmäisessä luvussa käsittelen Martti Lutherin teologiaa. Lutherilla moraalia edustaa Jumalan laki, jonka alaisuudesta kristitty pääsee vapaaksi kun Jeesus ottaa ristinkuolemassaan ihmisten synnin itselleen ja kärsii Jumalan lain mukaisen kuolemanrangaistuksen. Uskon yhteydessä Kristukseen kristitty kohoaa lain ulkopuolelle tekemään rakkauden tekoja. Toinen luku on omistettu Søren Kierkegaardin kristilliselle eksistentialismille. Kierkegaardin eksistenssitasojen filosofiassa uskonnollinen olemisen taso paljastuu korkeammaksi kuin eettinen. Tässä nousee tärkeäksi Kierkegaardin kirja Pelko ja vavistus. Kierkegaard tutkii Raamatun kertomusta Aabrahamista, jolle Jumala antaa käskyn uhrata oma poikansa Iisak. Kierkegaardille tarina on esimerkki eettistä korkeammasta ja sitä tilapäisesti vastustavasta olemisen tavasta. Kolmannessa luvussa käsittelen Dietrich Bonhoefferin teologiaa. Bonhoefferin mukaan Jeesus kutsuu ihmisiä seuraamaan häntä. Tämä on kutsu hyvän ja pahan tuolle puolen paratiisin viattomuuteen, joka rikkoo eettisyyden ihmisen ja Jeesuksen välillä. Neljännessä luvussa tarkastelen Friedrich Nietzschen filosofiaa ja pyrin ymmärtämään mitä hänen ohjelmansa hyvän ja pahan tuolle puolen tarkoittaa. Nietzschen vallantahdon filosofiassa moraali on heikkojen keino alistaa vahvat. Tarkastelen Nietzschen käsitystä moraalin synnystä ja sen haitallisuudesta ja pyrin selvittämään kuinka herrat elävät hyvän ja pahan tuolla puolen. Viidennessä luvussa tutkin Jaques Derridan grammatologiaa. Derridan mukaan teksti on suljettu tila, jonka ulkopuolelle on mahdoton päästä. Derrida sanoittaa kuitenkin sanoittamatonta tilattomuutta tekstin tuolla puolen. Tästä ei-paikasta käsin hypereettinen dekonstruktio purkaa perinteistä etiikkaa. Kuudennessa luvussa tarkastelen Mark C. Taylorin epä/teologiaa. Taylorille olotilan muutosta kuvaa termi harhautuminen , joka vie ihmisen lainsuojattomuuteen hyvän ja pahan tuolle puolen. Selvitän mitä harhautuminen tarkoittaa ja miten se liittyy Taylorin Jumalan kuoleman epä/teologiaan. Johtopäätösluvussa tuon esiin tutkimustuloksia, nostan esille joitain pääluvuissa esiintyviä teemoja ja vertaan tutkimuskohteitteni näkemyksiä toisiinsa. Lutherin ja Nietzschen perinteissä on paljon yhteistä, mutta pohjimmiltaan ne sotivat toisiaan vastaan. Hyvän ja pahan tuolle puolen johtaa kaksi polkua. Toinen niistä vie paratiisiin, toinen tuhoon.
