Työhön liittyvä kilpailu 18 - 65-vuotiaiden pyhtääläisten kuvaamana

Tutkimuksen kohteena olivat Pyhtään työikäisten asukkaiden näkemykset ja kokemukset työssä esiintyvästä kilpailusta Tutkimusongelma oli työhön liittyvän kilpailun ilmiön hahmottaminen. Tutkimuksen tarkoitus oli valottaa työhön liittyvän kilpailun moninaisuutta antaen esimerkkejä sen eri muodoista, esittäen ajatuksia uusien tulkintojen tekemiselle ja herättäen ideoita kilpailun eri muotojen soveltamiselle työn ja työilmapiirin tutkimuksissa. Tavoitteena oli tutkia haastatteluissa esiintyviä tapoja käsittää työhön liittyvä kilpailu ja sitä, missä määrin eri ammateissa kuvattiin sosiaalista kilpailua verrattuna välineelliseen kilpailuun. Työyhteisöön samastumista tarkasteltiin kilpailun ja koetun oikeudenmukaisuuden näkökulmista. Työn arvostusta käsiteltiin tarkastellen haastateltujen käsitystä ammattinsa yleisestä arvostuksesta sekä haastateltujen omia arvioita ammatistaan, sekä millä tavalla ammattirooli nousi esiin haastateltujen itsen kuvauksissa. Työpaikan ihmissuhteita ja valtaa tarkasteltiin kohdistamalla huomio työtovereiden kanssa toimeen tulemiseen ja työpaikan ihmissuhteiden aiheuttamaan stressiin sekä haastateltujen työssään kokeman oman vaikutusvallan, tasavertaisuuden, epäreiluuden, arvostuksen ja kilpailun määrään. Selvitettiin myös miten vallankäyttöä ja kiusaamista kuvattiin ja millä tavalla vallankäytön ja kiusaamisen katsottiin edesauttavan tavoitteiden saavuttamisessa. Lopuksi tarkastelun kohteina olivat ongelmien käsittely, työssä viihtyminen ja viihtymiseen vaikuttavat seikat. Aineisto kerättiin Pyhtäällä kesällä 2007. Vastaajia oli yhteensä 245 ja vastausprosentti oli 50. Tutkimuksessa mukana olivat kalkki työilmapiiriä ja työpaikan ihmissuhteita koskeviin kysymyksiin vastanneet haastatellut (N = 167). Suurimmaksi osaksi tutkimus oli kuvailevaa, mutta siinä oli myös kvantitatiivista kysymyksenasettelua. Tutkimuksessa käytettiin sekä kvalitatiivisia että kvantitatiivisia analyysimenetelmiä. Puolistrukturoiduissa yksilöhaastatteluissa hyödynnettiin tulkitsevaa fenomenologista analyysia. Kirjattuja avovastauksia tutkittiin luokittavalla ja tulkitsevalla sisällönanalyysilla. Lisäksi laskettiin tilastollisia merkitsevyyksiä Työpaikalla esiintyvä kilpailu nähtiin haastateltujen selonteoissa hyvin moninaisena, sekä myönteisenä että haitallisena. Siihen ymmärrettiin kuuluvan niin resursseihin, työtehtäviin, tuloksiin ja palkkioihin liittyvää välineellistä kilpailua, kuin ihmisten välistä sosiaalista valtataisteluakin. Suhteessa välineelliseen kilpailuun sosiaalista kilpailua kuvattiin eniten hoiva- ja sosiaalialan ammateissa. Suhteessa sosiaaliseen kilpailuun välineellistä kilpailua kuvasivat eniten yrittäjät Vastausten perusteella suun kilpailun määrä korreloi työpaikan ihmissuhteiden aiheuttamaan stressiin, mutta vain silloin, kun kokemus työpaikan oikeudenmukaisuudesta oli matala. Kilpailun eri muotojen (kilpailu omien tavoitteiden saavuttamisesta vs. kilpailu organisaation tavoitteiden saavuttamisesta) väliset yhteydet työyhteisöön samastumiseen eivät aineistossa olleet tilastollisesti merkitseviä. Haastatellun arvio oman ammattinsa arvostuksesta ei myöskään ennustanut haastatellun todennäköisyyttä esittää itsensä ammattikuntansa edustajana avoimen itsen kuvauksen tilanteessa. Koettu oikeudenmukaisuus kuitenkin korreloi työyhteisöön samastumiseen. Mitä oikeudenmukaisempana haastatellut työpaikkaansa pitivät, sitä tärkeämmäksi samastumiskohteeksi he sen tyypillisesti arvioivat. Myös työssä viihtymisen ja työpaikan koetun oikeudenmukaisuuden välinen korrelaatio oli aineistossa voimakas. Lisäksi silloin, kun kokemus oikeudenmukaisuudesta oli matalalla tasolla, oli myös työpaikan ihmissuhteiden aiheuttama stressi yhteydessä vähäiseen työssä viihtymiseen.

Deus vult: Images of crusader violence c. 1095-1100.

This study sets out to provide new information about the interaction between abstract religious ideas and actual acts of violence in the early crusading movement. The sources are asked, whether such a concept as religious violence can be sorted out as an independent or distinguishable source of aggression at the moment of actual bloodshed. The analysis concentrates on the practitioners of sacred violence, crusaders and their mental processing of the use of violence, the concept of the violent act, and the set of values and attitudes defining this concept. The scope of the study, the early crusade movement, covers the period from late 1080 s to the crusader conquest of Jerusalem in 15 July 1099. The research has been carried out by contextual reading of relevant sources. Eyewitness reports will be compared with texts that were produced by ecclesiastics in Europe. Critical reading of the texts reveals both connecting ideas and interesting differences between them. The sources share a positive attitude towards crusading, and have principally been written to propagate the crusade institution and find new recruits. The emphasis of the study is on the interpretation of images: the sources are not asked what really happened in chronological order, but what the crusader understanding of the reality was like. Fictional material can be even more crucial for the understanding of the crusading mentality. Crusader sources from around the turn of the twelfth century accept violent encounters with non-Christians on the grounds of external hostility directed towards the Christian community. The enemies of Christendom can be identified with either non-Christians living outside the Christian society (Muslims), non-Christians living within the Christian society (Jews) or Christian heretics. Western Christians are described as both victims and avengers of the surrounding forces of diabolical evil. Although the ideal of universal Christianity and gradual eradication of the non-Christian is present, the practical means of achieving a united Christendom are not discussed. The objective of crusader violence was thus entirely Christian: the punishment of the wicked and the restoration of Christian morals and the divine order. Meanwhile, the means used to achieve these objectives were not. Given the scarcity of written regulations concerning the use of force in bello, perceptions concerning the practical use of violence were drawn from a multitude of notions comprising an adaptable network of secular and ecclesiastical, pre-Christian and Christian traditions. Though essentially ideological and often religious in character, the early crusader concept of the practise of violence was not exclusively rooted in Christian thought. The main conclusion of the study is that there existed a definable crusader ideology of the use of force by 1100. The crusader image of violence involved several levels of thought. Predominantly, violence indicates a means of achieving higher spiritual rewards; eternal salvation and immortal glory.

F-18 Labelling Synthesis, Radioanalysis and Evaluation of A Dopamine Transporter and A Hypoxia Tracer

Positron emission tomography (PET) is an imaging technique in which radioactive positron-emitting tracers are used to study biochemical and physiological functions in humans and in animal experiments. The use of PET imaging has increased rapidly in recent years, as have special requirements in the fields of neurology and oncology for the development of syntheses for new, more specific and selective radiotracers. Synthesis development and automation are necessary when high amounts of radioactivity are needed for multiple PET studies. In addition, preclinical studies using experimental animal models are necessary for evaluating the suitability of new PET tracers for humans. For purification and analysing the labelled end-product, an effective radioanalytical method combined with an optimal radioactivity detection technique is of great importance. In this study, a fluorine-18 labelling synthesis method for two tracers was developed and optimized, and the usefulness of these tracers for possible prospective human studies was evaluated. N-(3-[18F]fluoropropyl)-2β-carbomethoxy-3β-(4-fluorophenyl)nortropane ([18F]β-CFT-FP) is a candidate PET tracer for the dopamine transporter (DAT), and 1H-1-(3-[18F]fluoro-2-hydroxypropyl)-2-nitroimidazole ([18F]FMISO) is a well-known hypoxia marker for hypoxic but viable cells in tumours. The methodological aim of this thesis was to evaluate the status of thin-layer chromatography (TLC) combined with proper radioactivity detection measurement systems as a radioanalytical method. Three different detection methods of radioactivity were compared: radioactivity scanning, film autoradiography, and digital photostimulated luminescence (PSL) autoradiography. The fluorine-18 labelling synthesis for [18F]β-CFT-FP was developed and carbon-11 labelled [11C]β-CFT-FP was used to study the specificity of β-CFT-FP for the DAT sites in human post-mortem brain slices. These in vitro studies showed that β-CFT-FP binds to the caudate-putamen, an area rich of DAT. The synthesis of fluorine-18 labelled [18F]FMISO was optimized, and the tracer was prepared using an automated system with good and reproducible yields. In preclinical studies, the action of the radiation sensitizer estramustine phosphate on the radiation treatment and uptake of [18F]FMISO was evaluated, with results of great importance for later human studies. The methodological part of this thesis showed that radioTLC is the method of choice when combined with an appropriate radioactivity detection technique. Digital PSL autoradiography proved to be the most appropriate when compared to the radioactivity scanning and film autoradiography methods. The very high sensitivity, good resolution, and wide dynamic range of digital PSL autoradiography are its advantages in detection of β-emitting radiolabelled substances.

Publishing in the Networked World: Transforming the Nature of Communication, 14th International Conference on Electronic Publishing 16-18 June 2010, Helsinki, Finland

The title of the 14th International Conference on Electronic Publishing (ELPUB), “Publishing in the networked world: Transforming the nature of communication”, is a timely one. Scholarly communication and scientific publishing has recently been undergoing subtle changes. Published papers are no longer fixed physical objects, as they once were. The “convergence” of information, communication, publishing and web technologies along with the emergence of Web 2.0 and social networks has completely transformed scholarly communication and scientific papers turned to living and changing entities in the online world. The themes (electronic publishing and social networks; scholarly publishing models; and technological convergence) selected for the conference are meant to address the issues involved in this transformation process. We are pleased to present the proceedings book with more than 30 papers and short communications addressing these issues. What you hold in your hands is a by-product and the culmination of almost a Year long work of many people including conference organizers, authors, reviewers, editors and print and online publishers. The ELPUB 2010 conference was organized and hosted by the Hanken School of Economics in Helsinki, Finland. Professors Turid Hedlund of Hanken School of Economics and Yaşar Tonta of Hacettepe University Department of Information Management (Ankara, Turkey) served as General Chair and Program Chair, respectively. We received more than 50 submissions from several countries. All submissions were peer-reviewed by members of an international Program Committee whose contributions proved most valuable and appreciated. The 14th ELPUB conference carries on the tradition of previous conferences held in the United Kingdom (1997 and 2001), Hungary (1998), Sweden (1999), Russia (2000), the Czech Republic (2002), Portugal (2003), Brazil (2004), Belgium (2005), Bulgaria (2006), Austria (2007), Canada (2008) and Italy (2009). The ELPUB Digital Library, http://elpub.scix.net serves as archive for the papers presented at the ELPUB conferences through the years. The 15th ELPUB conference will be organized by the Department of Information Management of Hacettepe University and will take place in Ankara, Turkey, from 14-16 June 2011. (Details can be found at the ELPUB web site as the conference date nears by.)

Campylobacter jejuni and C.coli in Finnish poultry production

Campylobacter, mainly Campylobacter jejuni and C. coli, are worldwide recognized as a major cause of bacterial food-borne gastroenteritis (World Health Organization 2010). Epidemiological studies have shown handling or eating of poultry to be significant risk factors for human infections. Campylobacter contamination can occur at all stages of a poultry meat production cycle. In summer 1999, every broiler flock from all three major Finnish poultry slaughterhouses was studied during a five month period. Caecal samples were taken in the slaughterhouses from five birds per flock. A total of 1 132 broiler flocks were tested and 33 (2.9%) of those were Campylobacter-positive. Thirty-one isolates were identified as C. jejuni and two isolates were C. coli. The isolates were serotyped for heat-stable antigens (HS) and genotyped by pulsed-field gel electrophoresis (PFGE). The most common serotypes found were HS 6,7, 12 and 4-complex. Using a combination of SmaI and KpnI patterns, 18 different PFGE types were identified. Thirty-five Finnish C. jejuni strains with five SmaI/SacII PFGE types selected among human and chicken isolates from 1997 and 1998 were used for comparison of their PFGE patterns, amplified fragment length polymorphism (AFLP) patterns, HaeIII ribotypes, and HS serotypes. The discriminatory power of PFGE, AFLP and ribotyping with HaeIII were shown to be at the same level for this selected set of strains, and these methods assigned the strains into the same groups. The PFGE and AFLP patterns within a genotype were highly similar, indicating genetic relatedness. An HS serotype was distributed among different genotypes, and different serotypes were identified within one genotype. From one turkey parent flock, the hatchery, six different commercial turkey farms (together 12 flocks) and from 11 stages at the slaughterhouse a total of 456 samples were collected during one and the half year. For the detection of Campylobacter both conventional culture and a PCR method were used. No Campylobacter were detected in either of the samples from the turkey parent flock or from the hatchery samples using the culture method. Instead PCR detected DNA of Campylobacter in five faecal samples from the turkey parent flock and in one fluff and an eggshell sample. Six out of 12 commercial turkey flocks were found negative at the farm level but only two of those were negative at slaughter. Campylobacter-positive samples within the flock at slaughter were detected between 0% and 94%, with evisceration and chilling water being the most critical stages for contamination. All of a total of 121 Campylobacter isolates were shown to be C. jejuni using a multiplex PCR assay. PFGE analysis of all isolates with KpnI restriction enzyme resulted in 11 PFGE types (I-XI) and flaA-SVR typing yielded nine flaA-SVR alleles. Three Campylobacter-positive turkey flocks were colonized by a limited number of Campylobacter genotypes both at the farm and slaughter level.In conclusion, in our first study in 1999 a low prevalence of Campylobacter in Finnish broiler flocks was detected and it has remained at a low level during the study period until the present. In the turkey meat production, we found that flocks which were negative at the farm became contaminated with Campylobacter at the slaughter process. These results suggest that proper and efficient cleaning and disinfection of slaughter and processing premises are needed to avoid cross-contamination. Prevention of colonization at the farm by a high level of biosecurity control and hygiene may be one of the most efficient ways to reduce the amount of Campylobacter-positive poultry meat in Finland. In Finland, with a persistent low level of Campylobacter-positive flocks, it could be speculated that the use of logistic slaughtering, according to Campylobacter status at farm, might have be advantageous in reducing Campylobacter contamination of retail poultry products. However, the significance of the domestic poultry meat for human campylobacteriosis in Finland should be evaluated.
