Associative Issue Ownership as a Determinant of Voters' Campaign Attention

Campaigns raise public interest in politics and allow parties to convey their messages to voters. However, voters' exposure and attention during campaigns are biased towards parties and candidates they like. This hinders parties' ability to reach new voters. This paper theorises and empirically tests a simple way in which parties can break partisan selective attention: owning an issue. When parties own issues that are important for a voter, that voter is more likely to notice them. Using survey data collected prior to the 2009 Belgian regional elections it is shown that this effect exists independent of partisan preferences and while controlling for the absolute visibility of a party in the media. This indicates that issue ownership has an independent impact on voters' attention to campaigns. This finding shows that owning salient issues yields (potential) advantages for parties, since getting noticed is a prerequisite for conveying electoral messages and increasing electoral success.

Kysynnän ennustaminen leipomotuotteille ja ennusteen tarkkuuden arviointi

Tässä diplomityössä tutkittiin kysynnän ennustamista Vaasan & Vaasan Oy:n tuotteille. Ensin työssä perehdyttiin ennustamiseen ja sen tarjoamiin mahdollisuuksiin yrityksessä. Erityisesti kysynnän ennustamisesta saatavat hyödyt käytiin läpi. Kysynnän ennustamisesta haettiin ratkaisua erityisesti ongelmiin työvuorosuunnittelussa.Työssä perehdyttiin ennustemenetelmiin liittyvään kirjallisuuteen, jonka oppien perusteella tehtiin koe-ennustuksia yrityksen kysynnän historiadatan avulla. Koe-ennustuksia tehtiin kuudelle eri Turun leipomon koe-tuotteelle. Ennustettavana aikavälinä oli kahden viikon päiväkohtainen kysyntä. Tämän aikavälin erityisesti peruskysynnälle etsittiin ennustetarkkuudeltaan parasta kvantitatiivista ennustemenetelmää. Koe-ennustuksia tehtiin liukuvilla keskiarvoilla, klassisella aikasarja-analyysillä, eksponentiaalisen tasoituksen menetelmällä, Holtin lineaarisella eksponenttitasoituksen menetelmällä, Wintersin kausittaisella eksponentiaalisella tasoituksella, autoregressiivisillä malleilla, Box-Jenkinsin menetelmällä ja regressioanalyysillä. Myös neuroverkon opettamista historiadatalla ja käyttämistä ongelman ratkaisun apuna kokeiltiin.Koe-ennustuksien tulosten perusteella ennustemenetelmien toimintaa analysoitiin jatkokehitystä varten. Ennustetarkkuuden lisäksi arvioitiin mallin yksinkertaisuutta, helppokäyttöisyyttä ja sopivuutta yrityksen monien tuotteiden ennustamiseen. Myös kausivaihteluihin, trendeihin ja erikoispäiviin kiinnitettiin huomiota. Ennustetarkkuuden huomattiin parantuvan selvästi peruskysyntää ennustettaessa, jos ensin historiadata esikäsittelemällä puhdistettiin erikoispäivistä ja –viikoista.

Prosessilähtöinen laadunarviointi ohutlevymekaniikkasopimusvalmistajan näkökulmasta

Diplomityö on tehty Lappeenrannan teknillisessä korkeakoulussa Konepajatekniikan laitoksella. Työ on osa Konepajatekniikan laitoksen toteuttamaa ”LELA” levytuotteiden laadunvalvontaprojektia. Projektiosapuolet olivat: Abloy Oy (Joensuu), Flextronics Enclosures (Oulu), Hihra Oy (Turku), Lillbacka Oy (Alahärmä), Nokia Networks (Oulu), Segerström & Svensson (Uusikaupunki) ja Scanfil Oy (Sievi). Lisäksi projektin pääasiallisena rahoittavana osapuolena toimi Teknologian kehittämiskeskus, Tekes. Työ perustui ohutlevykomponentteja valmistavissa kohdeyrityksissä suoritettuun laadunarviointitutkimukseen, joka sisälsi tuotantoon kohdistetun virhekartoituksen sekä laadunarviointikyselyn. Tutkimuksessa suoritetun tuotannon virhekartoituksen mukaan tyypillisessä ohutlevykomponentteja valmistavassa yrityksessä virheidenesiintymistodennäköisyys on n. 5 – 12 % / tuote. Eniten virheitä syntyi epäkeskopuristintöissä. Tutkimus osoittaa, että virhekartoituksen avulla yrityksen on mahdollista kartoittaa tuotannossa syntyvät virheet ja edelleen kohdistaa laadun kehitystoimenpiteet oikeisiin tuotannon osa-alueisiin.

Opettajan monikulttuurinen työ

Teacher's multicultural work The purpose of the present study is to explore teachers’ conceptions of their work as teachers of multicultural students. Teachers’ experiences of multicultural work and conceptions derived from them are part of the teacher’s multicultural competence which is seen as a key component of the teacher’s multicultural teachership. The teacher’s multicultural competence consists of the teacher’s cultural knowledge, pedagogical skills and experiences and attitudes related to multiculturalism. The teacher’s multicultural competence constitutes the basis on which the teacher implements multicultural education. The foundation for the teacher’s work is laid by laws and decrees, curricula, regulations issued by authorities in charge of the education of immigrant students, resources available and other demands and expectations set by the ambient society. The study was conducted in the city of Turku, Finland. The sample consisted of class teachers who taught both immigrant and majority students. Main objects of study in the theoretical part are the multicultural and pluralistic school and the multicultural teachership. The basic assumption is that the multicultural and pluralistic school forms the frame of activity in which the teacher implements multicultural teaching. The research strategy is based on methodological triangulation. The quantitative part of the study was carried out using a questionnaire typical of survey methods. The questionnaire was returned by 71 teachers. The qualitative part was conducted using theme-based interviews typical of phenomenological philosophical research. Of the total of teachers who returned the questionnaire, twelve (12) teachers were selected for interviews. According to the results, the participating teachers enjoyed their work regardless of the ample extra work caused by the students with immigrant backgrounds. The teachers experienced their work as teachers of multicultural student groups as strenuous, yet challenging. Students with immigrant backgrounds had caused many changes in the teacher’s work. The teachers regarded their multicultural skills as inadequate in relation to the demands of the work. They had not received education related to teaching students with immigrant backgrounds, but they were ready for in-service education. The teachers’ previous attitudes concerning immigrant students had been enforced. Teaching experiences strengthened the earlier, both positive and negative, attitudes. The central problems related to multiculturalism in the teacher’s work were caused by the deficient Finnish skills of the students with immigrant background. This was apparent in both teaching and learning as well as in contacts with parents. The teachers reported on relatively few inclusions of multicultural angles in their teaching. However, they believed that they could aid students with different cultural backgrounds in their integration process. At the same time they felt that their own chances to enhance the students’ cultural identities were slim. On the basis of the interviews conducted in connection with the teacher’s multicultural competence, the teachers were divided into three groups: assimilative, indeterminate and integrating multicultural teachers. The present study provides a strong indication that teachers tend to interpret multiculturalism in narrow terms. School activities, such as Finnish as a second language, first language and religious instruction, which were targeted exclusively at immigrant students were in most cases considered adequate. A holistic, cross-disciplinary, all-inclusive multicultural education that would permeate all school activities remains largely unimplemented.

Do standard burn mortality formulae work on a population of severely burned children and adults?

Accurate prediction of mortality following burns is useful as an audit tool, and for providing treatment plan and resource allocation criteria. Common burn formulae (Ryan Score, Abbreviated Burn Severity Index (ABSI), classic and revised Baux) have not been compared with the standard Acute Physiology and Chronic Health Evaluation II (APACHEII) or re-validated in a severely (≥20% total burn surface area) burned population. Furthermore, the revised Baux (R-Baux) has been externally validated thoroughly only once and the pediatric Baux (P-Baux) has yet to be. Using 522 severely burned patients, we show that burn formulae (ABSI, Baux, revised Baux) outperform APACHEII among adults (AUROC increase p<0.001 adults; p>0.5 children). The Ryan Score performs well especially among the most at-risk populations (estimated mortality [90% CI] original versus current study: 33% [26-41%] versus 30.18% [24.25-36.86%] for Ryan Score 2; 87% [78-93%] versus 66.48% [51.31-78.87%] for Ryan Score 3). The R-Baux shows accurate discrimination (AUROC 0.908 [0.869-0.947]) and is well-calibrated. However, the ABSI and P-Baux, although showing high measures of discrimination (AUROC 0.826 [0.737-0.916] and 0.848 [0.758-0.938]) in children), exceedingly overestimates mortality, indicating poor calibration. We highlight challenges in designing and employing scores that are applicable to a wide range of populations.

Determinación de la glucosa salival en adultos sanos

Objetivos: Determinar la concentración de glucosa salival de individuos sanos y compararla con la glicemia capilar. Diseño del estudio: Se realizó una recolección de saliva total en reposo, en 63 individuos no diabéticos. Se midió la concentración de glucosa salival y sanguinea capilar en todos los individuos. La glucosa salival fue determinada por método enzimático y espectrofotometría. Los datos fueron analizados usando el test de correlación de Spearman, considerando significativos valores de p<0,05. Resultados: Del total de la muestra, 47,6% eran varones y 52,4% mujeres, con una media de edad de 37,5±15,7 años. Las medias del flujo salival en reposo fueron de 0,41±0,2l ml/min en el género masculino y de 0,31±0,15 ml/min en el género femenino. No hubo diferencia significativa (p=0,07S). La media de glucosa sanguínea entre los varones fue de l00,05± 13,51 mg/dL y de 99 ,5± 13,9 mg/dL en las mujeres. La media de glucosa salival en el total de la muestra fue de 5,97±1 ,87 mg/dL, siendo 5,91±2, 19m9/dL en los varones y 5,97±1 ,56mg/dL en las mujeres, sin presentarse diferencias significativas (p=0,908). La concentración de la glucosa salival no presentó correlación estadísticamente significativa con la glicemia capilar (p=0,732). Conclusiones: De los resultados se desprende que: la concentración de la glucosa salival no depende de la glicemia capilar; la concentración de la glucosa salival no presenta diferencias entre géneros
