This paper addresses the ways in which humour is used by university academics to shape teaching personas. Based upon the work of Mauss and Foucault, and employing semi-structured, in-depth interviews with a range of university teachers, this research suggests that most tertiary teachers deliberately fashion various kinds of teaching persona, which they then perform in lectures and tutorials. The use of humour is widely seen as an important component within this form of self-shaping, as it fits within dominant frameworks of expectation regarding contemporary models of “edutainment”. This research demonstrates that a wide range of practices of the self—including physical, verbal, and relational elements—are employed by academics as part of shaping various humorous teaching personas. Some boundaries exist limiting the use of these pedagogic characters; for example, arguments about natural ability with humour prefigure who is most likely to deploy humour as a practice of professional self-formation. Also, professional concerns regarding seniority and job security are also factored into decision-making regarding those humorous personas likely to be considered appropriate within particular tertiary teaching contexts.

In semi-arid areas such as western Nebraska, interest in subsurface drip irrigation (SDI) for corn is increasing due to restricted irrigation allocations. However, crop response quantification to nitrogen (N) applications with SDI and the environmental benefits of multiple in-season (IS) SDI N applications instead of a single early-season (ES) surface application are lacking. The study was conducted in 2004, 2005, and 2006 at the University of Nebraska-Lincoln West Central Research and Extension Center in North Platte, Nebraska, comparing two N application methods (IS and ES) and three N rates (128, 186, and 278 kg N ha(-1)) using a randomized complete block design with four replications. No grain yield or biomass response was observed in 2004. In 2005 and 2006, corn grain yield and biomass production increased with increasing N rates, and the IS treatment increased grain yield, total N uptake, and gross return after N application costs (GRN) compared to the ES treatment. Chlorophyll meter readings taken at the R3 corn growth stage in 2006 showed that less N was supplied to the plant with ES compared to the IS treatment. At the end of the study, soil NO3-N masses in the 0.9 to 1.8 m depth were greater under the IS treatment compared to the ES treatment. Results suggested that greater losses of NO3-N below the root zone under the ES treatment may have had a negative effect on corn production. Under SDI systems, fertigating a recommended N rate at various corn growth stages can increase yields, GRN, and reduce NO3-N leaching in soils compared to concentrated early-season applications.

This study examined the nature and lifetime prevalence of two types of victimization among Finnish university students: stalking and violence victimization (i.e. general violence). This study was a cross-sectional study using two different datasets of Finnish university students. The stalking data was collected via an electronic questionnaire and the violence victimization data was collected via a postal questionnaire. There were 615 participants in the stalking study (I-III) and 905 participants in the violence victimization study. The thesis consists of four studies. The aims regarding the stalking substudies (Studies I-III) were to examine the lifetime prevalence of stalking among university students and to analyze how stalking is related to victim and stalker characteristics and certain central variables of stalking (victim-stalker relationship, stalking episodes, stalking duration). Specifically, the aim was to identify factors that are associated with stalking violence and to factors contributing to the stalking duration. Furthermore, the aim was also to investigate how university students cope with stalking and whether coping is related to victim and stalker background characteristics and to certain other core variables (victim-stalker relationship, stalking episodes, stalking duration, prior victimization, and stalking violence). The aims for the violence victimization substudy (Study IV) were to examine the prevalence of violence victimization, i.e. general violence (minor and serious physical violence and threats) and how violence victimization is associated with victim/abuser characteristics, symptomology, and the use of student health care services. The present study shows that both stalking and violence victimization (i.e. general violence) are markedly prevalent among Finnish university students. The lifetime prevalence rate for stalking was 48.5% and 46.5% for violence victimization. When the lifetime prevalence rate was restricted to violent stalking and physical violence only, the prevalence decreased to 22% and 42% respectively. The students reported exposure to multiple forms of stalking and violence victimization, demonstrating the diversity of victimization among university students. Stalking victimization was found to be more prevalent among female students, while violence victimization was found to be more prevalent among male students. Most of the victims of stalking knew their stalkers, while the offender in general violence was typically a stranger. Stalking victimization often included violence and continued for a lengthy period. The victim-stalking relationship and stalking behaviors were found to be associated with stalking violence and stalking duration. Based on three identified stalking dimensions (violence, surveillance, contact seeking), the present study found five distinct victim subgroups (classes). Along with the victim-stalker relationship, the victim subgroups emerged as important factors contributing to the stalking duration. Victims of violent stalking did not differ greatly from victims of non-violent stalking in their use of behavioral coping tactics, while exposure to violent stalking had an effect on the use of coping strategies. The victim-offender relationship was also associated to a set of symptoms regarding violence victimization. Furthermore, violence victimization had a significant main effect on specific symptoms (mental health symptoms, alcohol consumption, symptom index), while gender had a significant main effect on most symptoms, yet no interaction effect was found. The present results also show that victims of violence are overrepresented among frequent health care users. The present findings add to the literature on the prevalence and nature of stalking and violence victimization among Finnish university students. Moreover, the present findings stress the importance of violence prevention and intervention in student health care, and may be used as a guideline for policy makers, as well as health care and law enforcement professionals dealing with youth violence prevention.

The aim of this dissertation was to explore how different types of prior knowledge influence student achievement and how different assessment methods influence the observed effect of prior knowledge. The project started by creating a model of prior knowledge which was tested in various science disciplines. Study I explored the contribution of different components of prior knowledge on student achievement in two different mathematics courses. The results showed that the procedural knowledge components which require higher-order cognitive skills predicted the final grades best and were also highly related to previous study success. The same pattern regarding the influence of prior knowledge was also seen in Study III which was a longitudinal study of the accumulation of prior knowledge in the context of pharmacy. The study analysed how prior knowledge from previous courses was related to student achievement in the target course. The results implied that students who possessed higher-level prior knowledge, that is, procedural knowledge, from previous courses also obtained higher grades in the more advanced target course. Study IV explored the impact of different types of prior knowledge on students’ readiness to drop out from the course, on the pace of completing the course and on the final grade. The study was conducted in the context of chemistry. The results revealed again that students who performed well in the procedural prior-knowledge tasks were also likely to complete the course in pre-scheduled time and get higher final grades. On the other hand, students whose performance was weak in the procedural prior-knowledge tasks were more likely to drop out or take a longer time to complete the course. Study II explored the issue of prior knowledge from another perspective. Study II aimed to analyse the interrelations between academic self-beliefs, prior knowledge and student achievement in the context of mathematics. The results revealed that prior knowledge was more predictive of student achievement than were other variables included in the study. Self-beliefs were also strongly related to student achievement, but the predictive power of prior knowledge overruled the influence of self-beliefs when they were included in the same model. There was also a strong correlation between academic self-beliefs and prior-knowledge performance. The results of all the four studies were consistent with each other indicating that the model of prior knowledge may be used as a potential tool for prior knowledge assessment. It is useful to make a distinction between different types of prior knowledge in assessment since the type of prior knowledge students possess appears to make a difference. The results implied that there indeed is variation between students’ prior knowledge and academic self-beliefs which influences student achievement. This should be taken into account in instruction.

Tutkimuksen tarkoituksena oli selvittää, voidaanko oppimispäiväkirjaa käyttää kliinisen laboratoriotyönkäytännön opiskelijaohjaustoiminnassa oppimisen apuvälineenä. Tutkimuksessa lähdetään liikkeelle teoreettisten tietojen ja käytännön taitojen yhdistämisen tärkeydestä. Tutkimuksessa tarkastellaan oppimista kokemuksellisen oppimisen näkökulmasta ja kuinka se auttaa laboratoriohoitajaopiskelijaa laatimaan mieleensä käytännön opiskelun skeemoja ja kuinka ne toteutuvat heidän käytännön taitojen karttuessa. Tutkimukseen osallistui vuoden 1997 aikana HYKS:n laboratoriossa käytännön opiskelujaksolla olleita laboratoriohoitajaopiskelijoita. Heitä pyydettiin laatimaan käytännön opiskeluohjauksestaan oppimispäiväkirja. Laatiminen oli vapaaehtoista. Oppimispäiväkirjamerkinnöissä kiinnitettiin huomiota, kuinka he oppivatkäytännön taitoja ja kuinka heidän oppimisprosessinsa kehittyy heidän itsearvioimana. Jotkut laboratoriohoitajaopiskelijat halusivat laatia useammalta käytännön opiskelujaksoltaan oppimispäiväkirjan, joten oppimispäiväkirjoja (n=9) on enemmän kuin tutkimukseen osallistuneita laboratoriohoitajaopiskelijoita (n=6). Tutkimuksen keskeisenä menetelmenä on kvalitatiivinen analyysimenetelmä. Sisällönanalyysiä ja luokittelumenetelmää käyttäen pyrittiin löytämään käsityksiä ja niistä edelleen käsitysluokkia. Käsitysluokat tukivat sitä käsitystä, että oppimispäiväkirjaa voidaan käyttää apuvälineenä laboratoriohoitajaopiskelijoiden oppimisen tukena kliinisen laboratoriotyön käytännön opiskelussa. Tutkimustulokset osoittavat, että oppimispäiväkirjat toimivat laboratoriohoitajaopiskelijoiden tiedon jäsentäjinä käytännön opiskelujakson aikana. Oppimispäiväkirjan avulla laboratoriohoitajaopiskelija selventää itselleen kokonaiskuvaa kliinisen laboratoriotyön prosessista. Oppimispäiväkirjan avulla voidaan kerrata jo opittuja asioita ja voidaan suorittaa itsearviointia ja reflektoida oppimiskokemuksien antamia hyötyjä ja haittoja. Oppimispäiväkirjoissa tuli esille se, että laboratoriohoitajaopiskelijat selkiyttivät oppimiaan asioita ja omiaajatuksiaan suhteessa työelämään silloin, kun he kirjoittivat oppimispäiväkirjojaan. Oppimispäiväkirjojen kirjoittaminen koko käytännön opiskelujakson aikana tuki myös muiden käytännön opiskelujaksojen tavoitteiden asettamista. Oppimispäiväkirja on ammatillisen kehittymisen kannalta hyvä kertauksen, kriittisen ajattelun ja reflektoinnin väline. Oppimispäiväkirjoissa tuli kuvauksia itsearvioinnista, laboratoriohoitajaopiskelijat asettivat itsensä alttiiksi omalle arvioinnilleen hyvinkin helposti ja esittivät kriittisiä kannanottoja työskentelytapojen kehittämiseksi, huolellisuuden, tarkkuuden ja vastuuntunnon vahvistamiseksi. Tärkeimmät lähteet taustateorian kannalta olivat Engeströmin, Hätösen, Lonka & al, Leino-Kilven, Rauste-von Wrightin ja Silven & Kinnunen & Keskisen teokset. Tutkimusmenetelmän kannalta tärkeimmät lähteet olivat Hirsjärvi & Remes & Sajavaara, Lincoln & Cubanja Varton teokset. Avainsanat: Oppimispäiväkirja, reflektio, itsearviointi, kliininen laboratoriotyö, sisällönanalyysi
