Kansallisen kokonaismaanpuolustuksemme toimintaympäristö on kylmän sodan jälkeisellä ajalla ollut voimakkaassa muutoksessa. Globalisoituvassa maailmassa turvallisuushaasteet ja -uhat muodostavat keskinäisriippuvuuden verkoston, joiden vaikutuksiltaan laajat seuraukset iskevät lyhyillä varoitusajoilla yhä voimakkaammin, etäämmälle ja perinteisistä valtioiden rajoista välittämättä. Kansainvälisessä toiminnassa on vakiintumassa käsitteellisellä tasolla termi ”Comprehensive Approach”- kuvaamaan kokonaisvaltaista lähestymistapaa uusiin turvallisuushaasteisiin vastaamiseksi laajan turvallisuuden käsiteympäristössä. Miten tämä käsite ymmärretään Suomelle keskeisimpien toimijoiden, eli Euroopan Unionin, Yhdistyneiden Kansakuntien, Naton, Yhdysvaltojen tai vaikkapa Pohjoismaiden osalta? Kansallisen varautumisemme päämäärä on kuitenkin säilynyt vuosien saatossa samana. Sen tehtävänä on ollut varmistaa ja ylläpitää yhteiskuntamme elintärkeät toiminnot kaikissa tilanteissa kansalaisten elinmahdollisuuksien turvaamiseksi sekä valtion toimintakyvyn säilyttämiseksi. Varautumisemme kulmakiveksi on vuosikymmenten kuluessa muotoutunut kokonaismaanpuolustuksen konsepti, jonka avulla kaikki tärkeimmät kansalliset voimavaramme on kyetty keskittämään kohti yhteistä päämäärää kriisitilanteesta selviämiseksi sekä on estetty pienen valtion rajallisten resurssien päällekkäinen kehittäminen tai käyttö. Suomen kriisivalmiuden nykytila ja tulevaisuus on kuitenkin yhä tiiviimmin sidoksissa kansainväliseen kehitykseen. Syrjäinen sijaintimme, riippuvuus ulkomaankaupasta pitkine kulje-tusyhteyksineen, talouden kasvava integraatio, sähköisen viestinnän kehitys, teknologinen kustannusten kasvu sekä erikoistumisen vaatimus lisäävät jatkuvasti alttiuttamme erilaisille häiriöille ja lisäävät varautumisen kokonaiskustannuksia. Myös luonnon ääri-ilmiöiden voimistuminen, energiariippuvuuden lisääntyminen sekä sotilaallisten kriisinhallintaoperaatioiden luonteen muutos edellyttävät kansallisen varautumisemme perusrakenteiden aktiivista ja kehittävää tarkastelua. Tämän diplomityön keskeisenä tarkoituksena on löytää ja tunnistaa konstruktivismin teorian viitekehyksessä niitä kansainvälisen kehityksen trendejä ja muutospaineita, jotka mahdollistavat oman kansallisen kokonaismaanpuolustuksen mallimme kehittämisen. Samalla Suomelle tarjoutuu mahdollisuus vaikuttaa aktiivisella omalla toiminnallaan ja osaamisellaan kansainväliseen kehitykseen sekä verkottumalla hyödyntää globaalia osaamispääomaa. Esimerkkeinä tästä onnistuneesta kaksisuuntaisesta vaikuttamisesta esitellään tässä tutkimustyössä Suomen toiminta monikansallisessa suorituskykyjen kehittämistoiminnassa (MNE- eksperimentaatiosarja) sekä merivalvonta-alalla toteutettu monenvälinen yhteistyö.

Insufficient understanding of entrepreneurial opportunities characterizes entrepreneurship research (Companys & McMullen 2006, 302). Subsequently, the purpose of this study was to analyze the concept of entrepreneurial opportunity and to explore and synthetize the integrated theory of entrepreneurial opportunity. A theoretical and concept analytical approach was adapted. Findings of this study was that entrepreneurial opportunity concept was used for variety of different phenomena. No commonly accepted definition existed. Altogether 24 attributes that described the concept were found. The most frequently attached attributes were agent and action, new goods and services, market, value, new means ends or both, and future. Further, the results implied that opportunity could be best understood as a part of a process. Opportunity emerges out of intervened factors. Changes in the environment together with factors related to knowledge, cognition and social ties are the most important drivers of opportunity. Preventing factors that impeded the emergence of opportunity were typically related to cognitive and organizational factors. This study found a tendency towards more integrated theory of entrepreneurial opportunity. The integrated theory acknowledged the usefulness of both discovery and creation theories of opportunity in explaining opportunity. Yet three argument types of integrating two different opportunity theories were identified. These were process category, contextual category and complementing category. Opportunity is at the same time cognitive, social and linguistic construct, although it is shaped by the objective environment. Opportunity requires linguistic endeavors to become explicit. Materialization of opportunity occurs in a social context. Moreover, it is always characterized by some extent of subjectivity, as opportunities cannot appear without the agent and their action. Due to these the concept remains always to some extent ambiguous. Tolerating and harnessing change and investing in human and social capital create the preeminent environment for the entrepreneurial opportunity to be identified.

Abstract—This paper discusses existing military capability models and proposes a comprehensive capability meta-model (CCMM) which unites the existing capability models into an integrated and hierarchical whole. The Zachman Framework for Enterprise Architecture is used as a structure for the CCMM. The CCMM takes into account the abstraction level, the primary area of application, stakeholders, intrinsic process, and life cycle considerations of each existing capability model, and shows how the models relate to each other. The validity of the CCMM was verified through a survey of subject matter experts. The results suggest that the CCMM is of practical value to various capability stakeholders in many ways, such as helping to improve communication between the different capability communities.

The purposes of this study were: a) to examine the prevalence and consequences associated with adolescent gambling, b) to examine the factors which influence adolescent gambling,. c) to detennine what factors discriminate among four groups of gamblers (no-risk/non-gamblers, low-risk gamblers, at-risk gamblers, and high-risk/problematic gamblers), and d) to examine the relation of gambling to nine other risk behaviours (i.e., alcohol use, smoking, marijuana use, hard drug use, sexual activity, minor delinquency, major delinquency, direct aggression, and indirect aggression). Adolescents (N = 3,767) from 25 secondary schools completed a twohour survey that assessed involvement in risk be~aviours as well as potential predictors from a wide range of contexts (school, neighbourhood, family, peer, and intrapersonal). The majority of adolescents reported gambling, although the frequency of gambling participation was low. The strongest predictors/discriminators of gambling involvement were gender, unstructured activities, structured activities, and risk attitudes/perceptions. In addition, the examination of the co-occurrence of gambling with other risk behaviours revealed that for high-risk/problem gamblers, the top three most frequent co-occurring high-risk behaviours were direct aggression, minor delinquency and alcohol. This study was the first to examine the continuum of gambling involvement (i.e., non-gambling to high risk/problematic gambling) using a comprehensive set ofpotential predictors with a large sample of secondary school students. The findings of this study support past research and theories (e.g., Theory of Triadic Influence) which suggest the importance ofproximal variables in predicting risk behaviors. The next step, however, will be to examine the direct and indirect 1 effects of the ultimate (e.g., temperament), distal (e.g., parental relationship), and proximal variables (e.g., risk attitudes/perceptions) on gambling involvement in a longitudinal study.

As children are becoming increasingly inactive and obese, there is an urgent need for effective early prevention and intervention programs. One solution is a comprehensive school health (CSH) program, a health promotion initiative aimed at educating students about healthy behaviours and lifestyles, which also provides a link between the school, students, families, and the surrounding community. The purpose of this study was to explore the relationship between different components of CSH programs, as well as three determinants of health (gender, social support, socio-economic status), and physical activity, on the aerobic fitness and body mass index (BMI) of children. A newly developed and pilot-tested survey derived from Health Canada's fourpart CSH model (instruction, social support, support services, and a healthy physical environment) was sent to elementary school principals. Data on the gender, physical activity, parental education, and social support levels of students from these schools were gathered from a previous study. Multiple regression procedures were conducted to estimate the relationships between CSH components, the social determinants of health, physical activity, and BMI and aerobic fitness. Results showed that three CSH components were significantly associated with both BMI and aerobic fitness values in children, but accounted for less than 5% of the variance in both variables. Physical activity partially mediated the relationship between the significant CSH components, BMI, and particularly aerobic fitness. Furthermore, the social determinant and physical activity variables played independent roles in aerobic fitness values. No moderating effects of the social determinants were discovered.

The purpose of this ethnographic case study was to describe the characteristics of one school's Comprehensive School Health (CSH) initiative and to explore the experiences of school community members in order to gain an understanding of how one school embraced a Comprehensive School Health approach. An elementary school (grades Junior Kindergarten to six) in Burlington, Ontario was the research site for this study. Multiple methods of data collection (observations, document analysis, interviews) were used in keeping with the ethnographic and case study approach. The data were coded using both a deductive and then inductive process (Merriam, 1998). From a deductive perspective, the coding system and the subsequent identification of categories were based on a priori categories identified by using the elements of CSH based on the Comprehensive School Health Consensus Statement prepared by the Canadian Association of School Health and the research questions. Findings included the role that various school community members as well as the implementation of different programs and policies played in applying a CSH approach. The impact ofthe physical environment was described as well as successes and challenges related to the school's experience in implementing CSH. Three main themes emerged that characterized this school's experience. The first theme relates to the fundamental question about CSH which is the school community's understanding o/the concept. The second theme focused on positive school culture and the third and most diverse theme was that of capacity. Engaging in CSH is a complex and long-term undertaking involving both the school and greater community. Based on the experiences of this school's community members, recommendations address the different levels of influence on the health of children.

The purpose of this research is to describe the journey towards Comprehensive School Health at two Aboriginal elementary schools. An advocate and a healthy schools committee were identified at both schools and were responsible for developing initiatives to create a healthy school community. A case study was used to gather an in-depth understanding of Comprehensive School Health for the two schools involved. As a researcher, I functioned within the role of a participantobserver, as I was actively involved in the programs and initiatives completed in both schools. The research process included: the pilot study, ethics clearance and distribution of letters of invitation and consent forms. Data collection included 16 semi-structured, guided interviews with principals, teachers, and stupents. Participant observations included sites of the gymnasium, classroom, playgrounds, school environments, bulletin boards as well as artifact analysis of decuments such as school newsletters, physical education schedules and school handbooks. The interviews were transcribed and coded using an inductive approach which involves finding patterns, themes and categories from the data (patton, 2002). Research questions guided the findings as physical activity, physical education, nutrition and transportation were discussed. Themes developed t~rough coding were teacherstudent interactions, cultural traditions, time constraints and professional development and were discussed using a Comprehensive School Health framework.

The rationalizability of a choice function on arbitrary domains by means of a transitive relation has been analyzed thoroughly in the literature. Moreover, characterizations of various versions of consistent rationalizability have appeared in recent contributions. However, not much seems to be known when the coherence property of quasi-transitivity or that of P-acyclicity is imposed on a rationalization. The purpose of this paper is to fill this significant gap. We provide characterizations of all forms of rationalizability involving quasi-transitive or P-acyclical rationalizations on arbitrary domains.

Dans la foulée des scandales financiers ayant secoué le milieu des affaires ces dernières années, l’efficacité des pratiques de régie d’entreprise, et, en particulier celles liées à l’indépendance des administrateurs, a été passée au crible. L’administrateur désigné par une partie pour la représenter est un type d’administrateur que l’on rencontre fréquemment au sein des conseils d’administration des entreprises. Toutefois, l’on peut se questionner sur l’indépendance réelle de ces administrateurs, considérant leur loyauté envers la personne les ayant désignés, laquelle détient habituellement un intérêt à titre d’actionnaire ou de partie prenante dans l’entreprise visée. En outre, alors que les principes légaux requièrent que les administrateurs agissent dans le meilleur intérêt de l’entreprise, la réalité pratique est parfois toute autre: aux prises avec les instructions ou les souhaits de la personne les ayant nommés, les administrateurs désignés se retrouvent placés en situation inhérente de conflit d’intérêts. Ce texte vise à offrir une analyse détaillée au sujet de l’administrateur désigné et du conflit d’intérêts résultant de cette double exigence de loyauté. L’objectif est de présenter un examen approfondi des diverses difficultés résultant de la nomination d’un administrateur désigné ou associées à celle-ci, ainsi que des réponses judiciaires et législatives liées à cette problématique. Cette réflexion mènera à une exploration de certains systèmes législatifs et légaux, en particulier ceux du Royaume-Uni, de l’Australie et de la Nouvelle-Zélande, afin d’obtenir une meilleure compréhension et d’offrir une perspective éclairée quant aux enjeux analysés par la présente.

Le long bio-polymère d'ADN est condensé à l’intérieur du noyau des cellules eukaryotes à l'aide de petites protéines appelées histones. En plus de leurs fonctions condensatrices,ces histones sont également la cible de nombreuses modifications post-traductionnelles(MPT), particulièrement au niveau de leur section N-terminale. Ces modifications réversibles font partie d’un code d’histones épi-génétique transmissible qui orchestre et module dynamiquement certains événements impliquant la chromatine, tels l’activation et la désactivation de gènes ainsi que la duplication et la réparation d’ADN. Ces modifications sont impliquées subséquemment dans la signalisation et la progression de cancers, tels que la leucémie. En conséquence, l'élucidation des modifications d’histones est importante pour comprendre leurs fonctions biologiques. Une méthodologie analytique a été mise au point en laboratoire pour isoler, détecter, et quantifier les MPT d’histones en utilisant une approche rapide à deux volets à l’aide d’outils bioinformatiques spécialisés. La méthodologie développée en laboratoire a été validée en utilisant des histones de souche sauvage ainsi que deux types d’histones mutants déficients en enzymes acétyltransferase. Des trois sources d’histones utilisées, la seule MPT qui a démontré un changement significatif est l’acétylation de l’histone H3 à lysine 56 (H3K56ac). L’expression et la stoechiométrie de cette MPT, issue de cellules de souche sauvage et de cellules mutantes, ont été déterminées avec précision et comparées. Les fonctions de balayage polyvalentes d'un instrument à trappe ionique quadrupôle linéaire hybride ont été utilisées pour améliorer la détection de protéines intactes. Le mode de balayage « enhanced multiply charged » (EMC) a été modifié pour contenir et détecter les ions de protéines intactes situées dans la trappe ionique linéaire. Ce mode de balayage nommé « targeted EMC » (tEMC) a permis de quadrupler le niveau de sensibilité (signal/interférence), et quintupler la résolution du mode de balayage conventionnel. De plus, la capacité de séparation des charges du tEMC a réduit de façon significative les effets de « space charge » dans la trappe ionique linéaire. La résolution supérieure du mode tEMC a permis de différencier plusieurs isoformes modifiées, particulièrement pour l’histone H3. L’analyse des peptides d’histones trypsiques à l’aide du mode de balayage « MRM » a permis le séquençage et la quantification de MPT avec un haut degré de précision. La seule MPT qui était sous-exprimée entre l’histone de souche sauvage et le mutant DOT1L fut la méthylation de l’histone H3 lysine 79(H3K79me1). Les effets de deux inhibiteurs d’enzymes HDAC (HDACi) sur l’expression de MPT d’histone ont été évalués en utilisant la méthodologie analytique mentionnée. Les histones extraites de cellules normales et cancéreuses ont été exposées à du Vorinostat(SAHA) ou du Entinostat (MS-275) pour une période de 24 à 72 heures. Deux histones furent principalement affectées, soit H3 et H4. Étonnamment, les mêmes effets n'ont pas été détectés lorsque les cellules normales ont été traitées avec le HDACi pour une période de 48 à 72 heures. Une méthode absolue de quantification avec une courbe d’étalonnage a été développée pour le peptide H3K56ac. Contrairement à certaines publications, nos résultats démontrent que cette MPT est présente dans les cellules mammifères avec une stoechiométrie très basse (< 0,1%) et n'est pas surexprimée de façon significative après le traitement au HDACi.
