Elämänkokemukset ja koherenssin tunne – typologinen tutkimus grounded theory -metodologiaa soveltaen

Tutkimuksen tarkoituksena on laadullisin menetelmin syventää tietoa työikäisten (28–60-vuotiaiden) suomalaisten kvantitatiivisesti mitatun koherenssin tunteen takana olevista tekijöistä. Tutkimuksella halutaan tuottaa aineistolähtöisesti tietoa siitä, mitkä käsitteet kuvaavat tutkittavien kerrottujen elämänkokemusten kautta selvitettyä koherenssin tunnetta ja samalla lisäämään ymmärrystä Antonovskyn salutogeenisesta teoreettisesta mallista. Tutkimukseen osallistuneet olivat Health and Social Support tutkimukseen vuosina 1998 ja 2003 osallistuneita. Koko kyseinen tutkimusotos edusti vuonna 1998 20–24, 30–34, 40–44 ja 50–54 -vuotiasta Suomen väestöä. Tutkimuksen metodina käytettiin glaserilaista grounded theory -metodologiaa. Tutkimuksen aineistonkeruu toteutettiin kolmessa eri vaiheessa. Ensimmäisessä vaiheessa haastateltiin 27 tutkittavaa. Toisessa vaiheessa haastateltavilta kerättiin lisäaineistoa kirjallisesti. Kahdeksan vastasi tähän pyyntöön. Kolmannessa vaiheessa haastateltiin seitsemää. Haastattelujen yhteydessä haastateltavat täyttivät koherenssin tunteen mittarin (13-osainen). Aineisto analysoitiin koherenssipisteiden mukaisesti kolmena eri aineistona. Tulokseksi saatiin substantiivinen teoria. Tutkimuksen tuloksena kuvattiin sosiaalinen perusprosessi, joka nimitettiin Elämän kokonaisuudeksi tässä hetkessä. Sosiaalisen perusprosessin sisällä on typologia. Jokaisesta koherenssipisteryhmästä muodostettiin oma typologia. Kukin typologia sisälsi neljä tyyppiä. Sosiaalisen perusprosessin vaiheet olivat: ehdot tämän hetken taustalla, eläminen ehtojen varassa ja uusia luoden (tietynlainen ihminen, eläminen tässä hetkessä, kokonaisnäkemys elämästä) sekä jatkaminen ehtojen varassa ja uusia luoden. Typologiat ovat nimeltään eheät, pärjäävät ja sinnittelijät. Haastateltavien kokemuksia ei analyysivaiheessa pyritty liittämään tiettyyn kontekstiin, vaan ne liittyivät toimintaan ja käyttäytymiseen. Tulosten tarkasteluvaiheessa tehtiin kuitenkin lyhyt kuvaus elämänkulkututkimuksesta sekä sosiaalisesta ja kulttuurisesta ympäristöstä. Tutkimustulokset ovat kuvailevia ja niiden perusteella saadaan viitteitä siitä, millaiset asiat ovat yhteydessä koherenssin tunteeseen ja millä tavalla yhteys rakentuu. Saatu substantiivinen teoria on pätevä tässä aineistossa. Tulokset noudattelevat Antonovskyn salutogeenista teoreettista mallia siltä osin, että mitä korkeammat koherenssipisteet olivat, sitä enemmän typologiassa oli eheyttä lisääviä tekijöitä. Eheys tuo elämään henkistä liikkumavaraa, jota typologian tyypit (rakentava, ilmavasti elävä, elämänmyönteinen, juureva realisti) ilmentävät. Typologioiden kuvauksista voidaan lukea, että kaikissa tyypeissä kuvataan vaikeita elämänkokemuksia. Olennaista on se, miten näihin vaikeuksiin suhtaudutaan. Eheillä on parhaat edellytykset käsitellä elämän haasteita. Voidaan kuitenkin todeta, että kaikki tähän tutkimukseen osallistuneet olivat selviytyjiä.

Social ventures : the development of the theory of sustainable contributive advantage and initial empirical tests

This thesis attempts to fill gaps in both a theoretical basis and an operational and strategic understanding in the areas of social ventures, social entrepreneurship and nonprofit business models. This study also attempts to bridge the gap in strategic and economic theory between social and commercial ventures. More specifically, this thesis explores sustainable competitive advantage from a resource-based theory perspective and explores how it may be applied to the nonmarket situation of nonprofit organizations and social ventures. It is proposed that a social value-orientation of sustainable competitive advantage, called sustainable contributive advantage, provides a more realistic depiction of what is necessary in order for a social venture to perform better than its competitors over time. In addition to providing this realistic depiction, this research provides a substantial theoretical contribution in the area of economics, social ventures, and strategy research, specifically in regards to resource-based theory. The proposed model for sustainable contributive advantage uses resource-based theory and competitive advantage in order to be applicable to social ventures. This model proposes an explanation of a social venture’s ability to demonstrate consistently superior performance. In order to determine whether sustainable competitive advantage is in fact, appropriate to apply to both social and economic environments, quantitative analyses are conducted on a large sample of nonprofit organizations in a single industry and then compared to similar quantitative analyses conducted on commercial ventures. In comparing the trends and strategies between the two types of entities from a quantitative perspective, propositions are developed regarding a social venture’s resource utilization strategies and their possible impact on performance. Evidence is found to support the necessity of adjusting existing models in resource-based theory in order to apply them to social ventures. Additionally supported is the proposed theory of sustainable contributive advantage. The thesis concludes with recommendations for practitioners, researchers and policy makers as well as suggestions for future research paths.

Towards conceptually comprehensive and integrated theory of entrepreneurial opportunity

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.

Grounded theory -tutkimusmenetelmä ja sen käyttö akateemisissa julkaisuissa

Työn tavoitteena on selvittää mitä on grounded theory, miten se on sovellettavissa akateemisissa julkaisuissa ja miten eri julkaisujen grounded theory -tutkimukset eroavat toisistaan. Työ on toteutettu järjestelmällisesti analysoimalla neljän markkinointia käsittelevän lehden julkaisemat GT-tutkimukset vuosina 2000-2012. Tuloksina havaitaan lehdille tyypillisiä ominaispiirteitä. Tarkastelun kohteena ovat tutkimusotannat, tutkimusprosessit, tutkimusten aihealueet sekä tutkimuksissa esitetyt lopputulokset. Lisäksi työssä tarkastellaan havaittuja trendejä grounded theory tutkimuksissa sekä pohditaan tutkimusmenetelmän tulevaisuutta. Perinteinen GT-tutkimus on tietyissä akateemisissa lehdissä yhä yleisesti käytetty menetelmä, mutta sen soveltava käyttö, sekä monimenetelmäiset tutkimukset ovat selvässä kasvussa.

In this paper, a systematic and quantitative view is presented for the application of the theory of constraints in manufacturing. This is done employing the operational research technique of mathematical programming. The potential of the theory of constraints in automated manufacturing is demonstrated.

Application of the center manifold theory to the study of slewing flexible Non-ideal structures with nonlinear curvature: a case study

In this paper is Analyzed the local dynamical behavior of a slewing flexible structure considering nonlinear curvature. The dynamics of the original (nonlinear) governing equations of motion are reduced to the center manifold in the neighborhood of an equilibrium solution with the purpose of locally study the stability of the system. In this critical point, a Hopf bifurcation occurs. In this region, one can find values for the control parameter (structural damping coefficient) where the system is unstable and values where the system stability is assured (periodic motion). This local analysis of the system reduced to the center manifold assures the stable / unstable behavior of the original system around a known solution.

Det planlagda och det som visar sig : klasslärarstuderandes syn på undervisning i teknisk slöjd

Sloyd as an activity concretizes man’s ability to, with the help of mind and body, reshape materials into objects and change her conditions for survival. The sloyd actor outside school works when the spirit moves her, while the pupil in school is expected to sloyd regardless of motivation. Subject teachers become experts on sloyd in educational settings, while the qualification requirements may set the class teachers’ voluntariness within parenthesis. All class teachers qualify to teach all core subjects of the national curriculum in Finland from preschool to grade six. The aim of the current thesis is to deepen the knowledge on how the science of sloyd education can support class teacher students’ future teaching in sloyd. In the empirical part of the study, Swedish-speaking Finnish class teacher students’ views on technical sloyd as one of their future subjects for teaching are examined. The class teacher’s qualifying skills in teaching technical sloyd are expected to take shape during only a few ECTS study points. The teacher students’ experience of the subject from the pupil’s perspective is supposed to move into a budding teacher subject. In a research-based teacher education, self-reflection and reflection as a dialogue are extended aided by research results. Intuitive thinking interplays with rational thinking during this time. The teacher student’s approach to make use of the autonomous free space in teaching is, in the current thesis, as considerations where the individual weighs the pros and cons in relation to various phenomena in sloyd and the school overall. The basis for an individual autonomy is shaped and is expected to interplay on the common arena of autonomy. In the exercise of their profession, the class teacher teaching sloyd is expected to oscillate between the sloyd educational practice and theory. The first step in this movement within the teacher education is the coverage of a selection of theories during the studies. The empirical part of the study is carried out at two separate occasions with directed open-ended interviews with fifteen class teacher students in the beginning and end of their first year of study. The data was analysed with a hermeneutic approach and a qualitatively oriented approach to content analysis. The results are mirrored against theory within the science of sloyd education. The results show that class teacher students have a versatile view of educational sloyd. The overall results overthrow parts of the researcher’s pre-understanding. The viewpoint of the students seems to broaden from a merely manual activity to seeing sloyd as an educational activity. In order for the results to gain significance in the teacher education of the future, a line of reasoning is conducted in order to recommend an extended dialogue and thirteen possible themes for enriching discussions are put forth as a result of the present study. The extended dialogue focuses on that teacher education should make conscious ventures to create opportunities for the students to take part in effective discussions on the subject of sloyd, complementing the existing dialogue between the teacher educator and the students. This thesis lends support to reflections on the following aspects of educational sloyd in these dialogues: the reasons for why the sloyd subject exists, the ambitions of the subject, the content and organization of the subject for students as well as for the teacher educators.

A Modified phosphate-carrier protein theory is proposed as a non-target site mechanism For glyphosate resistance in weeds

Glyphosate is an herbicide that inhibits the enzyme 5-enolpyruvyl-shikimate-3-phosphate synthase (EPSPs) (EC 2.5.1.19). EPSPs is the sixth enzyme of the shikimate pathway, by which plants synthesize the aromatic amino acids phenylalanine, tyrosine, and tryptophan and many compounds used in secondary metabolism pathways. About fifteen years ago it was hypothesized that it was unlikely weeds would evolve resistance to this herbicide because of the limited degree of glyphosate metabolism observed in plants, the low resistance level attained to EPSPs gene overexpression, and because of the lower fitness in plants with an altered EPSPs enzyme. However, today 20 weed species have been described with glyphosate resistant biotypes that are found in all five continents of the world and exploit several different resistant mechanisms. The survival and adaptation of these glyphosate resistant weeds are related toresistance mechanisms that occur in plants selected through the intense selection pressure from repeated and exclusive use of glyphosate as the only control measure. In this paper the physiological, biochemical, and genetic basis of glyphosate resistance mechanisms in weed species are reviewed and a novel and innovative theory that integrates all the mechanisms of non-target site glyphosate resistance in plants is presented.
