School Bullies’ Quest for Power: Implications for Group Dynamics and Intervention

Bullying is characterized by an inequality of power between perpetrator and target. Findings that bullies can be highly popular have helped redefine the old conception of the maladjusted school bully into a powerful individual exerting influence on his peers from the top of the peer status hierarchy. Study I is a conceptual paper that explores the conditions under which a skillful, socially powerful bully can use the peer group as a means of aggression and suggests that low cohesion and low quality of friendships make groups easier to manipulate. School bullies’ high popularity should be a major obstacle for antibullying efforts, as bullies are unlikely to cease negative actions that are rewarding, and their powerful position could discourage bystanders from interfering. Using data from the Finnish program KiVa, Study II supported the hypothesis that antibullying interventions are less effective with popular bullies in comparison to their unpopular counterparts. In order to design interventions that can address the positive link between popularity and aggression, it is necessary to determine in which contexts bullies achieve higher status. Using an American sample, Study III examined the effects of five classroom features on the social status that peers accord to aggressive children, including classroom status hierarchy, academic level and grade level, controlling for classroom mean levels of aggression and ethnic distribution. Aggressive children were more popular and better liked in fifth grade relative to fourth grade and in classrooms of higher status hierarchy. Surprisingly, the natural emergence of status hierarchies in children’s peer groups has long been assumed to minimize aggression. Whether status hierarchies hinder or promote bullying is a controversial question in the peer relations’ literature. Study IV aimed at clarifying this debate by testing the effects of the degree of classroom status hierarchy on bullying. Higher hierarchy was concrrently associated with bullying and predictive of higher bullying six months later. As bullies’ quest for power is increasingly acknowledged, some researchers suggest teaching bullies to attain the elevated status they yearn for through prosocial acts. Study V cautions against such solutions by reviewing evidence that prosocial behaviors enacted with the intention of controlling others can be as harmful as aggression.

Nuori vertaisryhmässä : tekeekö seura kaltaisekseen?

Naisyrittäjien välinen vertaistuki, Case: Yrittäjyyden Tuki-projekti

Yrittäjyyden Tuki - projekti toimi osana valtakunnallista WomEqual - kehittämiskumppanuushanketta vuosina 2005-2007 tavoitteenaan tukea naisyrittäjien toimintaedellytyksiä kehittäen heille vertaisryhmätoimintaan perustuvaa tukimallia. Tässä tutkimuksessa ensisijaisena tavoitteena on selvittää, miten kyseisen projektin vertaisryhmätoimintaan osallistuneet naisyrittäjät kokivat naisyrittäjien välisen vertaistuen toimintamuotona. Pyrkimyksenä on myös ymmärtää, mitkä seikat sitouttivat naisyrittäjiä vertaisryhmätoimintaan ja mitä he kokivat oppineensa vertaisryhmätoiminnan seurauksena. Lisäksi kiinnostuksen kohteena on tarkastella, kuinka vertaistukiryhmä toimii naisyrittäjien välisen verkostoitumisen välineenä. Tutkimus on laadullinen ja aineistolähtöinen. Tutkimuksen primääriaineisto on kerätty puolistrukturoiduin teemahaastatteluilla ja sekundaariaineisto kyselytutkimuksen avulla. Tutkimustulokset osoittavat, että naisyrittäjät kokevat henkisen ja sosiaalisen tuen tärkeäksi. Toiselta naisyrittäjältä, vertaiselta, saatu tuki koettiin vertaistukiryhmän vahvuudeksi. Vertaisryhmässä oppiminen tapahtui kokemusten jakamisen kautta. Uusien verkostojen luomisessa vertaistukiryhmä ei täysin vastannut odotuksia.

Lentopetrolin hinnanmuutoksilta suojautuminen johdannaisilla Case Jetflite Oy

Tutkielman tavoitteena on selvittää, miten lentoyhtiöt, kuten case-yritys Jetflite Oy, voivat hyödyntää johdannaisinstrumentteja suojautuessaan polttoainekustannusten nousulta. Tutkielmassa kootaan tietoa eri lentoyhtiöiden riskienhallintastrategioista ja niiden implementoinnissa käytetyistä johdannaissopimustyypeistä. Tutkielmassa pyritään tuottamaan tietoa case-yrityksen johdolle riskienhallintastrategian luomista varten kartoittamalla toteutuneita polttoainekustannuksia Jetfliten ostolaskuista. Lentoyhtiöt voivat määritellä suojausstrategian, jonka mukaisesti määrättynä ajanjaksona haluttu osuus tulevista polttoainehankinnoista suojataan johdannaissopimuksin muun muassa futuureita, optioita ja swappeja käyttäen. Johdannaisia käytetään sekä lähitulevaisuuden polttoainehankintojen suojauksissa että pitkän aikavälin riskienhallintastrategioita toteutettaessa. Koska polttoainekustannukset ovat lentoyhtiöiden toiminnan kannattavuuden kannalta keskeinen kuluerä, on em. kustannusten nousulta suojautuminen lentoyhtiöille myös strateginen menestystekijä.

Induction practices : experiences of newly qualified teachers

The thesis consists of four studies (articles I–IV) and a comprehensive summary. The aim is to deepen understanding and knowledge of newly qualified teachers’ experiences of their induction practices. The research interest thus reflects the ambition to strengthen the research-based platform for support measures. The aim can be specified in the following four sub-areas: to scrutinise NQTs’ experiences of the profession in the transition from education to work (study I), to describe and analyse NQTs’ experiences of their first encounters with school and classroom (study II), to explore NQTs’ experiences of their relationships within the school community (study III), to view NQTs’ experiences of support through peer-group mentoring as part of the wider aim of collaboration and assessment (study IV). The overall theoretical perspective constitutes teachers’ professional development. Induction forms an essential part of this continuum and can primarily be seen as a socialisation process into the profession and the social working environment of schools, as a unique phase of teachers’ development contributing to certain experiences, and as a formal programme designed to support new teachers. These lines of research are initiated in the separate studies (I–IV) and deepened in the theoretical part of the comprehensive summary. In order to appropriately understand induction as a specific practice the lines of research are in the end united and discussed with help of practice theory. More precisely the theory of practice architectures, including semantic space, physical space-time and social space, are used. The methodological approach to integrating the four studies is above all represented by abduction and meta-synthesis. Data has been collected through a questionnaire survey, with mainly open-ended questions, and altogether ten focus group meetings with newly qualified primary school teachers in 2007–2008. The teachers (n=88 in questionnaire, n=17 in focus groups), had between one and three years of teaching experience. Qualitative content analysis and narrative analysis were used when analysing the data. What is then the collected picture of induction or the first years in the profession if scrutinising the results presented in the articles? Four dimensions seem especially to permeate the studies and emerge when they are put together. The first dimension, the relational ˗ emotional, captures the social nature of induction and teacher’s work and the emotional character intimately intertwined. The second dimension, the tensional ˗ mutable, illustrates the intense pace of induction, together with the diffuse and unclear character of a teacher’s job. The third dimension, the instructive ˗ developmental, depicts induction as a unique and intensive phase of learning, maturity and professional development. Finally, the fourth dimension, the reciprocal ˗ professional, stresses the importance of reciprocity and collaboration in induction, both formally and informally. The outlined four dimensions, or integration of results, describing induction from the experiences of new teachers, constitute part of a new synthesis, induction practice. This synthesis was generated from viewing the integrated results through the theoretical lens of practice architecture and the three spaces, semantic space, physical space-time and social space. In this way, a more comprehensive, refined and partially new architecture of teachers’ induction practices are presented and discussed.

Same- and Other-Sex Victimization : Risk Factors, Consequences, and Protection by Peers

Bullying can be viewed as goal-oriented behavior in the strive for dominance and prestige in the peer group (Salmivalli, 2010). To ensure the effectiveness of their power demonstrations, bullies often choose targets from among their vulnerable peers (Salmivalli, 2010; Veenstra et al., 2007). A large number of studies have also shown that victimization has severe consequences for the victims’ psychosocial adjustment (Reijntjes, Kamphuis, Prinzie, & Telch, 2010; Ttofi, Farrington, Lösel, & Loeber, 2011). In this thesis I investigate – based on three empirical studies – whether similar dynamics on the risk factors and consequences apply to same- and other-sex victimization. In the empirical studies, we used the data from the randomized control trial of the KiVa antibullying program for the elementary school grades 4–6 (2007–2008), and for the middle school grades 7–9 (2008–2009). We measured same- and other-sex victimization, and victims’ defending relationships by dyadic questions: “By which classmates are you victimized?” and “By which classmates are you supported, comforted, or defended?” In addition, we used self-reports and peer reports to measure adjustment and social status. The findings imply that other-sex victimization may be challenging for antibullying work. First, although targets of bullying seemed to be selected from among vulnerable peers for the most part, perceived popularity increased the risks of other-sex victimization. Popularity of these victims may falsely lead to an impression that the victims are doing well. Second, the consequences considering victims’ later psychosocial adjustment were alarming concerning girls bullied by boys. Thus, despite the fact that the targets may be perceived as popular, other-sex victimization can have even more severe consequences than same-sex victimization. Third, we found that defending relationships were mostly same-sex relationships, and consequently, we may ask whether defending is effective against other-sex bullies. Finally, the KiVa antibullying program was less effective against other-sex victimization in the adolescent sample. The findings altogether emphasize the importance of taking into account the sex composition of the bully-victim dyad, both considering future research on bullying and in the antibullying work with children and adolescents.

The effects of potentiallydisruptive technology on business model - a case study of new technologies in ICT industry

This study examines how firms interpret new, potentially disruptive technologies in their own strategic context. The work presents a cross-case analysis of four potentially disruptive technologies or technical operating models: Bluetooth, WLAN, Grid computing and Mobile Peer-to-peer paradigm. The technologies were investigated from the perspective of three mobile operators, a device manufacturer and a software company in the ICT industry. The theoretical background for the study consists of the resource-based view of the firm with dynamic perspective, the theories on the nature of technology and innovations, and the concept of business model. The literature review builds up a propositional framework for estimating the amount of radical change in the companies' business model with two middle variables, the disruptiveness potential of a new technology, and the strategic importance of a new technology to a firm. The data was gathered in group discussion sessions in each company. The results of each case analysis were brought together to evaluate, how firms interpret the potential disruptiveness in terms of changes in product characteristics and added value, technology and market uncertainty, changes in product-market positions, possible competence disruption and changes in value network positions. The results indicate that the perceived disruptiveness in terms ofproduct characteristics does not necessarily translate into strategic importance. In addition, firms did not see the new technologies as a threat in terms of potential competence disruption.

Online peer to peer lending: clustering borrowers using self-organizing maps

The purpose of this thesis is to find out whether all the peer to peer lenders are unworthy of credit and also if there are single qualities or combinations of qualities that determine the probability of default of a person or group of people. Distinguishing qualities are searched with self-organizing maps (SOM). Qualities and groups of people found by the self-organizing map are then compared to the average. The comparison is carried out by looking how big proportion of borrowers meeting the criteria is two months or more behind with their payments. Research data used is collected by an Estonian peer to peer lending company during the years of 2011-2014. Data consists of peer to peer borrowers and information gathered from them.
