Social Cognition and Behavior in Relationship Context

Social information processing (SIP; Crick & Dodge, 1994) and social-cognitive learning theories have been often used to understand children’s problem behaviors, such as aggression. According to these theories, children’s thinking guides their subsequent behaviors. Although most of us agree that social behavior and underlying thought processes are context-dependent, personality and social development researchers have usually engaged in searching for stable patterns of dispositions and behaviors, ignoring (or treating as error) the variance across different situations and relationship types. This, however, can result in erroneous conclusions and question the interpretation of previous findings. Four studies were conducted to explore the influence of relationship context on children’s social-cognitive evaluations and behavior. Samples were fourth to sixth graders from Estonia and Finland. Social cognitions were assessed by presenting children with hypothetical vignettes where the previously identified relationship partner’s behavior had a negative consequence for the child (Studies I, II, and IV), followed by questions measuring different social-cognitive processes (e.g., hostile attributions, behavioral strategies, outcome expectations and self-efficacy beliefs for aggression). In addition, in Studies II and IV, children provided information about their behavior within a specific relationship context. In Study III, an affective priming paradigm was employed where participants were presented with a short display of photographs of children’s liked and disliked classmates, and unknown peers. The results of this thesis suggest that children’s thinking and behavior are largely influenced by the affective valence of the relationship. Moreover, cognitions guide behavior within the relationship. The current findings offer a fruitful avenue for studying the heterogeneity of peer interactions.

TV taskussa - tänään ja tulevaisuudessa

The objective of my thesis was to find out how mobile TV service will influence TV consumption behaviour of the Finns. In particular the study focuses on the consumption behaviour of a well educated urban people. For my thesis, I provided a detailed analysis of the study results of a large scale questionnaire research FinPilot from the year 2005 based on an assignment of Nokia Ltd. In order to deepen the study results, I focused on the above mentioned group of young people with good education. The goal of the FinPilot research was to give answers to the following questions: what kind of programs, in what kind of circumstances, and for which reasons are they watched when using the mobile television service. The results of the research consisted mainly of data like figures, graphics etc. The data was explaned from the helicopter perspective, for it gave additional value to the research and consequently to my own thesis. My study offered complementary, unique information about their needs as it was based on questionnaires supplemented by individual interviews of the group members, their free comments as well as group discussions. The study results proved that mobile TV service did not increase the total TV consumption time. The time used for watching the mobile TV was significantly shorter than the time for watching the traditional TV. According to my study, the young urban people with good education are more interested to adapt the mobile TV service than the average Finns. Being eager to utilize the added value offered by the mobile TVs they are a potential target group in launching and marketing processes. On the basis of the outcome of the thesis, the future of mobile TV service seems very promising. The content and the pricing, however, have to match the user's needs and expectations. All the study results prove that there exists a social order for mobile TV service.

Expectations of elderly people on the nurse-client relationship and interaction in home care : "When I see the nurse's smiling face it feels likes sunshine on a rainy and gloomy day"

The purpose of the thesis was to explore expectations of elderly people on the nurse-client relationship and interaction in home care. The aim is to improve the quality of care to better meet the needs of the clients. A qualitative approach was adopted. Semi-structured theme interviews were used for data collection. The interviews were conducted during spring 2006. Six elderly clients of a private home care company in Southern Finland acted as informants. Content analysis was used as the method of data analysis. The findings suggest that clients expect nurses to provide professional care with loving-kindness. Trust and mutual, active interaction were expected from the nurse-client relationship. Clients considered it important that the nurse recognizes each client's individual needs. The nurse was expected to perform duties efficiently, but in a calm and unrushed manner. A mechanic performance of tasks was considered negative. Humanity was viewed as a crucial element in the nurse-client relationship. Clients expressed their need to be seen as human beings. Seeing beyond the illness was considered important. A smiling nurse was described to be able to alleviate pain and anxiety. Clients hoped to have a close relationship with the nurse. The development of a close relationship was considered to be more likely if the nurse is familiar and genuine. Clients wish the nurses to have a more attending presence. Clients suggested that the work areas of the nurses could be limited so that they would have more time to transfer from one place to another. Clients felt that they would benefit from this as well. The nurses were expected to be more considerate. Clients wished for more information regarding changes that affect their care. They wished to be informed about changes in schedules and plans. Clients hoped for continuity from the nurse-client relationship. Considering the expectations of clients promotes client satisfaction. Home care providers have an opportunity to reflect their own care behaviour on the findings. To better meet the needs of the clients, nurses could apply the concept of loving-kindness in their work, and strive for a more attending presence.

"Typically German" - Cultural Expectations and Experiences

Tutkielman tavoite ja tutkimusmenetelmät Tutkielman päätavoitteena oli selvittää millaisia stereotyyppisiä odotuksia ihmisillä liike-elämässä on saksalaisista. Tutkimusmenetelmä oli laadullinen tutkimus ja aineistonkeruumenetelmänä käytettiin teemahaastatteluja. Haastatteluilla saatua materiaalia täydennettiin ja peilatiin managementkirjallisuudesta poimituilla kuvauksilla saksalaisista. Johtopäätökset Tutkielman empiriaosassa muodostettiin kolme erillistä stereotyyppiä saksalaisista. Suomalaisten kuva saksalaisista oli suhteellisen yhtenäinen, kun taas kansainvälisissä mielikuvissa oli enemmän hajontaa. Rehellisyys, järjestelmällisyys, muodollisuus ja laadun tuottaminen olivat yleisesti hyväksyttyjä "saksalaisia ominaisuuksia". Toisin kuin auto-stereotypiat yleensä, vaikutti saksalaisten kuva omasta kansallisuudestaan suhteellisen negatiiviselta.

Peso problem anddevaluation expectations: Evidence from Latin America

Tämän tutkielman tavoitteena on tutkia peso-ongelmaa sekä devalvaatio-odotuksia seuraavissa Latinalaisen Amerikan maissa: Argentiina, Brasilia, Costa Rica, Uruguay ja Venezuela. Lisäksi tutkitaan, onko peso-ongelmalla mahdollista selittää korkojen epäsäännöllistä käyttäytymistä ennen todellisen devalvaation tapahtumista. Jotta näiden tutkiminen olisi mahdollista, lasketaan markkinoiden odotettu devalvaation todennäköisyys tutkittavissa maissa. Odotettu devalvaation todennäköisyys lasketaan aikavälillä tammikuusta 1996 joulukuuhun 2006 käyttäen kahta erilaista mallia. Korkoero-mallin mukaan maiden välisestä korkoerosta on mahdollista laskea markkinoiden devalvaatio-odotukset. Toiseksi, Probit-mallissa käytetään useita makrotaloudellisia tekijöitä selittävinä muuttujina laskettaessa odotettua devalvaation todennäköisyyttä. Lisäksi tutkitaan, miten yksittäisten makrotaloudellisten muuttujien kehitys vaikuttaa odotettuun devalvaation todennäköisyyteen. Empiiriset tulokset osoittavat, että tutkituissa Latinalaisen Amerikan maissa oli peso-ongelma aikavälillä tammikuusta 1996 joulukuuhun 2006. Korkoero-mallin tulosten mukaan peso-ongelma löytyi kaikista muista tutkituista maista lukuun ottamatta Argentiinaa. Vastaavasti Probit-mallin mukaan peso-ongelma löytyi kaikista tutkituista maista. Tulokset osoittavat myös, että korkojen epäsäännöllinen kehitys ennen varsinaista devalvaatiota on mahdollista selittää peso-ongelmalla. Probit-mallin tulokset osoittavat lisäksi, että makrotaloudellisten muuttujien kehityksellä ei ole mitään tiettyä kaavaa liittyen siihen, kuinka ne vaikuttavat markkinoiden devalvaatio-odotuksiin Latinalaisessa Amerikassa. Pikemmin vaikutukset näyttävät olevan maakohtaisia.

European Union Eastern Enlargement - Expectations and Experiences of Doing Business in the New Member States

Customer Expectations and Organizational Buying Behavior in the Flexible Packaging Markets

Tämä työ on tehty yhteistyössä kansainvälisen metsäteollisuusyrityksen Stora Enson kanssa. Työ on osa Stora Enson strategiaa kehitettäessä uusia ja innovatiivisia pakkausmateriaaleja ja ratkaisuja joustopakkausmarkkinoille. Työn päätavoitteina oli selvittää, millaisia odotuksia tuotemerkkienomistajilla ja jatkojalostajilla on joustopakkauksista ja kuinka pakkausten ostopäätökset syntyvät monitahoisessa liikeympäristössä. Työn teoreettinen viitekehys jaettiin kahteen osaan. Asiakasodotuksia lähestyttiin tutkimalla eri palvelu- ja tuotelaadun ulottuvuuksia, ja teollisuuden ostokäyttäytymistä tutkittiin organisaatioiden ostokäyttämistä kuvaavien mallien avulla. Työn empiirisessä osuudessa käytettiin laadullista tutkimusmenetelmää käsittäen asiakashaastatteluja lähinnä Yhdysvalloissa. Haastateltavat yritykset koostuivat maailman johtavista kuluttajatuotteita valmistavista yrityksistä sekä jatkojalostajista. Tutkimustulosten mukaan odotukset pakkauksista liittyvät lähinnä tuotteen suojaamiseen sekä myynnin edistämiseen. Pääodotuksina on myös saada mahdollisimman edullisia papereita, mahdollisimman hyvillä barrier- ja paino-ominaisuuksilla. Tutkimustulokset osoittavat myös, että paperiyhtiöt ovat epäonnistuneet tekemään itseään tunnetuksi teollisuudelle ja heidän odotetaan olevan tulevaisuudessa aggressiivisempia ja innovatiivisempia. Tuotemerkkienomistajat ostavat pakkaukset ja pakkausmateriaalit normaalisti mieluiten jatkojalostajiensa kautta, mutta silti he toivovat yhteistyötä paperintoimittajien kanssa kunhan vain myös jatkojalostajat sisällytetään toimintaan mukaan.

Hammaslääkärin ura. Odotukset ja kokemukset. [Career Expectations and Experiences of Dentists]

Tutkimuksella selvitettiin eri tekijöiden merkitystä hammaslääkärien tehdessä uraansa koskevia valintoja lähtien ammatinvalinnasta. Tutkimuksessa verrattiin erilaisissa työpaikoissa toimivien hammaslääkärien sekä hammaslääketieteen opiskelijoiden odotuksia ja kokemuksia. Tutkimus tehtiin kyselynä postitse lähetetyin lomakkein. Kyselyyn osallistui 350 hammaslääkäriä ja 115 opiskelijaa. Kiinnostus lääketieteeseen ja työn konkreettisuus olivat keskeisimmät syyt lähteä hammaslääketiedettä opiskelemaan. Suurin osa sekä hammaslääkäreistä että opiskelijoista valitsisi vähintään todennäköisesti saman ammatin uudelleen, hammaslääkäreistä yksityishammaslääkärit useimmin. 69 % hammaslääkäreistä oli aloittanut työuransa terveyskeskuksessa, opiskelijoista 46 % toivoi työpaikkaa yksityissektorilta ja 37 % terveyskeskuksesta. Hammaslääkärit kokivat työn mielekkyyden, positiivisen kaiun, työn ja elämän reunaehtojen sekä taloudellisen turvallisuuden vaikuttaneen ensimmäiseen työpaikkaan menoon vähemmän kuin opiskelijat arvioivat niiden vaikuttavan. Työssä tärkeänä sekä hammaslääkärit että opiskelijat pitivät hyviä työolosuhteita ja mielekästä työn sisältöä. Toimiva yhteistyö työparin kanssa oli myös erittäin tärkeää. Hammaslääkärit pitivät hyviä työoloja ja autonomiaa tärkeämpinä kuin opiskelijat, joille puolestaan uralla eteneminen ja työajan joustot olivat tärkeämpiä. Hammaslääkärit arvostivat työtä ja työssä suoriutumista sekä hyvää työpaikkaa enemmän kuin opiskelijat. Parhaiten työssään toteutuvana suhteessa asian merkitykseen hammaslääkärit kokivat autonomian ja huonoiten ilmapiirin. Naiset kokivat asioiden toteutumisessa enemmän puutteita kuin miehet. Työpaikkaansa heikosti sitoutuneita oli 8 %, joista valtaosa terveyskeskushammaslääkäreitä. Heikosti sitoutuneet kokivat sitoutuneita huonompina varsinkin työilmapiirin, työolosuhteet ja mahdollisuuden uralla etenemiseen. Hammaslääkärit olivat halukkaampia jatkokoulutukseen kuin kokivat siihen olevanmahdollisuuksia; 25 % oli harkinnut erikoistumista, mutta luopunut ajatuksesta, ja20 % halusi erikoistua, mutta koki siihen käytännön esteitä. Jatkossa tulisi tarkemmin analysoida ja toistettavin tutkimuksin seurata hammaslääkärien urakokemuksia ja valintoja sekä koetun työssä vallitsevan tilanteen ja asioiden merkityksen välistä suhdetta. Myös opiskelijoiden urasuunnitelmia ja arvostuksia tulisi tutkia säännöllisin väliajoin.

Expectations and Experiences of International Students in Information Technology Department

Education in Finland plays a significant role. International students are becoming an essential part of Finnish Educational system. The study was meant to examine their expectations and experiences in a Finnish University. As a case, Lappeenranta University of Technology (LUT) was chosen and, in particular, Information Technology (IT) Department. The main objectives of the study were to examine students’ satisfaction of their study experiences, their evaluation of the teaching quality of courses and last but not least the cultural impact on those. Data for the study were mainly collected with the help of three Internet surveys from a sample of 50 students – currently studying at LUT or already graduated. Response rate from questionnaire to questionnaire varied, however, still close to average and was considered as good and relevant enough. The study was initially meant as qualitative, however, a number of quantitative data analysis methods were used as well. Most of students’ expectations appear to become true, majority of students are satisfied with their experiences. Results show that teaching quality in LUT is evaluated as ‘good’. Nevertheless, students prefer particular courses to the other ones. In conclusion, it can be said that culture does affect students’ expectations, experiences, perception of the world, however, cultural differences do not cause any serious problems.

Trolley R&D project for a small portal log yard crane

This master’s thesis was done for Andritz Inc. Atlanta Georgia. The purpose of the thesis was to develop a new trolley for a small portal log yard crane. In the beginning of the thesis the basic principles of the systematic design processes have been described, along which the design work of the trolley has proceeded. The second literature part consists of the design and dimensioning of the welded steel structures under fatigue loading. The design work of the trolley consists of the engineering and the selection of the mechanical components and the design of the load carrying structure for the trolley. The realization of the steel structure of the trolley is based on the fatigue and static dimensioning. The fatigue dimensioning is grounded in the life expectations estimated for the trolley and the static dimensioning is based on the CMAA guidelines. The computer aided element method was utilized in the design of the steel structure. The effective notch method and the hot spot method were used in the fatigue calculations. The trolley structure was carried out by using the sheet metal parts in order to manufacture the structure as effective and low cost way as possible. The corner stone of the dimensioning of the trolley structure was the utilization of the open profiles made of welded or cold formed sheet metals, which provide better weldability, weld inspection, access for repairs and corrosion protection. As a last part of the thesis a new trolley traveling system was developed. The distribution of the wheel loads of the trolley bogies on the main girder was also studied, which led to an innovative suspension arrangement between the trolley leg and the bogie. The new bogie solution increases the service life of the main girder of the crane and improves the stability of the bogies. The outcome of the thesis is an excellent trolley structure from the weight and the service life point of view.

The effect of the birth hospital and the time of birth on the outcome of Finnish very preterm infants

The purpose of this study was to evaluate the effect of the birth hospital and the time of birth on mortality and the long-term outcome of Finnish very low birth weight (VLBW) or very low gestational age (VLGA) infants. This study included all Finnish VLBW/VLGA infants born at <32 gestational weeks or with a birth weight of ≤1500g, and controls born full-term and healthy. In the first part of the study, the mortality of VLBW/VLGA infants born in 2000–2003 was studied. The second part of the study consisted of a five-year follow-up of VLBW/VLGA infants born in 2001–2002. The study was performed using data from parental questionnaires and several registers. The one-year mortality rate was 11% for live-born VLBW/VLGA infants, 22% for live-born and stillborn VLBW/VLGA infants, and 0% for the controls. In live-born and in all (including stillbirths) VLBW/VLGA infants, the adjusted mortality was lower among those born in level III hospitals compared with level II hospitals. Mortality rates of live-born VLBW/VLGA infants differed according to the university hospital district where the birth hospital was located, but there were no differences in mortality between the districts when stillborn infants were included. There was a trend towards lower mortality rates in VLBW/VLGA infants born during office hours compared with those born outside office hours (night time, weekends, and public holidays). When stillborn infants were included, this difference according to the time of birth was significant. Among five-year-old VLBW/VLGA children, morbidity, use of health care resources, and problems in behaviour and development were more common in comparison with the controls. The health-related quality of life of the surviving VLBW/VLGA children was good but, statistically, it was significantly lower than among the controls. The median and the mean number of quality-adjusted life-years were 4.6 and 3.6 out of a maximum five years for all VLBW/VLGA children. For the controls, the median was 4.8 and the mean was 4.9. Morbidity rates, the use of health care resources, and the mean quality-adjusted life-years differed for VLBW/VLGA children according to the university hospital district of birth. However, the time of birth, the birth hospital level or university hospital district were not associated with the health-related quality of life, nor with behavioural and developmental scores of the survivors at the age of five years. In conclusion, the decreased mortality in level III hospitals was not gained at the expense of long-term problems. The results indicate that VLBW/VLGA deliveries should be centralized to level III hospitals and the regional differences in the treatment practices should further be clarified. A long-term follow-up on the outcome of VLBW/VLGA infants is important in order to recognize the critical periods of care and to optimise the care. In the future, quality-adjusted life-years can be used as a uniform measure for comparing the effectiveness of care between VLBW/VLGA infants and different patient groups

Salivary gland cancer in Finland: Incidence, histological distribution, outcome and prognostic factors

Salivary gland cancer (SGC) is a rare cancer. The histological classification of SGC is complex and its biological behavior highly variable: it may vary from a low-grade tumor to a high-grade and often fatal malignancy. These circumstances make this cancer a diagnostic and therapeutic challenge. Older age and exposure to ionizing radiation are known risk factors. The mainstay of treatment is surgery combined with adjuvant radiation therapy, when appropriate. In addition to the histological type, the only well known prognostic factor is the TNM classification, which describes the tumor size and the amount of metastases. This study was performed using a full population-based nationwide cohort of SGC patients and tumors diagnosed in Finland in 1991-1996. The annual incidence of SGC in the entire population was, on average, 47.7 per year. By histological re-evaluation of 237 specimens the most frequent histological types were the adenoid cystic carcinoma (n=65; 27%), the mucoepidermoid carcinoma (n=45; 19%) and the acinic cell carcinoma (n=41; 17%). The highest 10-year disease-specific survival rate occurred among patients with acinic cell carcinoma (90%), followed by mucoepidermoid carcinoma (81%) and adenoid cystic carcinoma (60%). A high volume-corrected index (VCI) of Ki-67 correlated with worse survival of patients with SGC. Computer-assisted morphometric analyses of CD34-positive vessels indicated an unfavorable prognosis for patients with mucoepidermoid carcinoma and an association with poor survival among patients with acinic cell carcinoma. A high level of expression of matrix metalloproteinase-9 (MMP-9) showed a trend for a poorer prognosis in salivary duct carcinoma, and a high level of MMP-13 and a low level of MMP-1 had a trend for a poorer prognosis of patients with SGC. A low level of MMP-7 was associated with a poor prognosis of patients with acinic cell and mucoepidermoid carcinoma.

Delivery, Outcome, and Costs of Orthodontic Care in Finnish Health Centres

The goal of the study was to analyse orthodontic care in Finnish health centres with special reference to the delivery, outcome and costs of treatment. Public orthodontic care was studied by two questionnaires sent to the chief dental officers of all health centres (n = 276) and to all specialist orthodontists in Finland (n = 146). The large regional variation was mentioned by the orthodontists as the most important factor requiring improvement. Orthodontic practices and outcome were studied in eight Finnish municipal health centres representing early and late timing of treatment. A random sample of 16- and 18-year-olds (n = 1109) living in these municipalities was examined for acceptability of occlusion with the Occlusal Morphology and Function Index (OMFI). In acceptability of occlusion, only minor differences were found between the two timing groups. The percentage of subjects with acceptable morphology was higher among untreated than among treated adolescents. The costs of orthodontic care were estimated among the adolescents with a treatment history. The mean appliance costs were higher in the late, and the mean visit costs higher in the early timing group. The cost-effectiveness of orthodontic services differed among the health centres, but was almost equal in the two timing groups. National guidelines and delegation of orthodontic tasks were suggested as the tools for reducing the variation among the health centres. In the eight health centres, considerable variation was found in acceptability of occlusion and in cost-effectiveness of services. The cost-effectiveness was not directly connected with the timing of treatment.

Treatment of Acute Otitis Media

Background: Acute otitis media (AOM) is the most common bacterial infection in young children, but the optimal management of AOM remains controversial. The aim of this study was to assess the efficacy of antimicrobial treatment, either immediate or delayed, for AOM and to compare parental experiences regarding the management of AOM in two countries with very different treatment guidelines. Methods: Altogether, 322 children participated in a randomized, double-blind, placebocontrolled trial. Children 6–35 months of age with AOM received amoxicillin-clavulanate or placebo for 7 days. The primary outcome was the time to treatment failure. In the second study, the delayed antimicrobial treatment group consisted of recipients of placebo who had received rescue treatment. The immediate antimicrobial treatment group consisted of children allocated to amoxicillin-clavulanate group. Parental expectations and opinions were evaluated by questionnaires sent via public day care in Turku, Finland, and Utrecht, the Netherlands. Results: Treatment failure occurred significantly more often in children receiving placebo as compared to antimicrobial treatment (45% vs. 19%, P<0.001). Delayed initiation of antimicrobial treatment did not worsen the recovery from AOM, but it was associated with worsening of the child’s condition, prolongation of symptoms, and absenteeism from day care and parental absenteeism from work. According to the comparative questionnaire, antimicrobial use was more common in Finland than in the Netherlands. Finnish parents believed more often than Dutch parents that antimicrobials are necessary in the treatment of AOM. Conclusions: Children with AOM benefit from antimicrobial treatment. Delayed initiation of antimicrobial does not worsen the overall recovery from AOM, but it might increase the symptom burden and create economic losses. Treatment practices and parental expectations seem to interact with each other. This needs to be considered when AOM treatment guidelines are updated.
