Frequency of B cells in normal mice which recognize self proteins

The mechanism whereby the immune system avoids self-aggression is one of the central issues of Immunology. The discovery of natural autoantibodies, mainly of IgM isotype, and of idiotypic interactions between antibodies indicates that elements of the immune system interact with self constituents and with themselves. Results of studies with soluble antibodies have indicated that the pool of circulating IgM represents the end result of a highly selective process of B cells activation and differentiation by self proteins resulting in the formation of a network. The objective of the present work was to determine the frequency of self-reacting B cells in normal mice. We were able to detect B cells that recognize self proteins present in extracts of different organs in normal adult, 2-3-month old, BALB/c and C57BL/6 mice with an ELISA spot assay. About 1% of total IgM-secreting cells among small, LPS-stimulated spleen cells reacted with organ extracts, whereas among large spleen cells the frequency was 5- to 10-fold lower. Immunization induced an increase in the frequency of IgM-secreting cells. The present results provide cellular evidence for the results of studies done at the serological level. The physiological role of these self-recognizing cells, as well as their participation in autoimmune processes, remain to be established

Imbuing airborne electronic warfare self-protection : possibilities to disguise

Tutkielman nimi käännettynä suomeksi on Lentokoneiden omasuojajärjestelmien kyllästäminen – mahdollisuuksia kätkeytymiseen. Siinä keskitytään etsimään aktiivisia, ilmauhkaa kohti säteileviä keinoja ilmahyökkääjän, lentokoneen tai helikopterin, omasuojajärjestelmän harhauttamiseksi. Järjestelmät pyrkivät varoittamaan lentäjää laser- ja tutkasäteilyhavainnoista sekä ohjuksen laukaisusta ja lähestymisestä. Omasuojajärjestelmiin kuuluviin vastakeinoihin tutkimus ei keskity. Tavoitteena harhauttamisella on ilmapuolustuksen todellisen määrän ja sijainnin suojaaminen. Epätietoisuus voi saada lentäjän tekemään vääriä johtopäätöksiä. Työ ei fokusoi harhauttamisen taktiseen kehykseen työn kannalta tarpeellista määrää enempää. Tietosuojasyistä tutkimus ei käsittele käytössä olevien omasuojajärjestelmien operatiivisia ominaisuuksia vaan käsittelee teoriaa niiden taustalla. Tutkimus tehtiin käyttäen taustatutkimukselle enemmän tyypillistä kirjallisuustutkimusta. Jo tutki-muksen alkuvaiheessa oli oletettavaa, että elektronisiin sensoreihin perustuvaa omasuojajärjestelmää pystytään harhauttamaan. Systeemianalysoinnilla pyrittiin löytämään vastauksia tähän olettamukseen. Omasuojajärjestelmästä muodostettiin jo tutkimuksen varhaisessa vaiheessa malli. Tieteellistä kirjallisuutta omasuojajärjestelmistä on olemassa jonkin verran, ja niistä löydettyä tietoa omasuojajärjestelmien ominaisuuksista ja sensoreista yhdistettiin malliin niin, että siitä saatiin mahdollisimman tarkka systeemin kuvaus todellisesta omasuojajärjestelmästä. Analyysin tavoitteena oli löytää niitä kriteereitä, joilla omasuojajärjestelmä saataisiin kohtuullisen tehokkaasti uskomaan harhautusta oikeaksi hälytykseksi. Ohjuksen laukaisusta varoittava sensori perustuu ohjuksen moottorin muodostaman pilven lämpö-säteilyyn. Säteily kuitenkin muuttuu lennon eri vaiheissa, mikä tuottaa haasteita järjestelmälle. Millimetrialueen tutkan käyttö varoittimen sensorina on myös yksi vaihtoehto. Laser-varoittimet toimivat koko sillä taajuusalueella, mitä sotilaskäytössä tulenjohtamiseen ja ohjusten ohjaamiseen käytetään. Tutkavaroittimen tutkimus on vielä kesken. Löydettyjä tuloksia analysoimalla tulen tässä vaiheessa hieman ristiriitaisiin tuloksiin. Lämpösäteilyn käytön suurin haaste on sen eteneminen ilmakehässä. Varoittimen tavoitekaan ei ole toimia kymmentä kilometriä pidemmälle. Yksi mahdollinen ratkaisu on suunnitella ja toteuttaa raketti, jonka tuottaa lämpösäteilyä kuten tietty puolustavan joukon käytössä oleva ohjus. Jos koneessa on kuitenkin myös millimetrialueen tutka tukemassa varoitusjärjestelmää, hankaloituu rakettiharhautus merkittävästi, koska sen pitäisi oletettavasti olla lentokoneen kanssa melko tarkasti kohtaavalla reitillä. Laser-varoitin on ilmeisesti herkin järjestelmistä, koska se voi tietyissä olosuhteissa ja varsinkin matalalla lentokorkeudella aiheuttaa paljon vääriä hälytyksiä ilman tarkoituksellista harhauttamista. Laserin käyttö yhdistettynä raketin laukaisuun saattaisi tuottaa halutun tuloksen. Tutkavaroittimen harhautus onnistuu, jos valelaitteen signaali on uskottavan tarkka.

Digital Humanities For Everyone’s Benefit?: interplay in social media with the great audience, high-esteemed researcher and self-conscious library

The National Library of Finland realizes the Digitization Project of Kindred Languages in 2012–15. The project is financially supported by the Kone Foundation. During this project the National Library of Finland has digitized and made available approximately 1200 monograph and more than 100 newspaper titles in several Uralic languages. The materials are available to both researchers and citizens in the National Library’s Fenno-Ugrica collection. The project will produce digitized materials in the Uralic languages as well as their development tools to support linguistic research and citizen science. The resulting materials will constitute the largest resource for the Uralic languages in the world. Through this project, researchers will gain access to corpora which they have not been able to study before and to which all users will have open access regardless of their place of residence. In my presentation, I will discuss 1) how we utilized the social media (Facebook, Twitter, VKontakte etc) to gain audience for our collection and 2) how the needs of researchers and laymen were met in crowdsourcing.

Mistä on hyvät tytöt tehty? Somalitytöt ja maineen merkitykset

Tutkimus käsittelee islaminuskoisten somalityttöjen hyvään ja huonoon maineeseen liittyviä uskonnollisia, kulttuurisia ja etnisiä määrittelyjä ja niiden merkityksiä heidän arjessaan. Turussa hankittu etnografinen tutkimusaineisto koostuu osallistuvaan havainnointiin perustuvasta kenttäpäiväkirja-aineistosta sekä kahdestakymmenestäviidestä 17‒35-vuotiaiden somalityttöjen ja -naisten teemahaastattelusta vuosilta 2003–2006. Tutkimuksen tehtävänä on selvittää, minkälaista somalityttöä pidetään maineeltaan hyvänä ja miten tytön maine voi mennä. Tutkimuksessa tarkastellaan yhtäältä sitä, mikä merkitys sosiaalisilla verkostoilla on tyttöjen maineen määrittelyssä. Toisaalta kysytään, mitä somalitytöt ja nuoret naiset itse ajattelevat tytön maineeseen liittyvistä odotuksista ja miten he niistä tietoisina toimivat. Lähestymistapa rakentuu uskontotieteen, antropologian, sukupuolentutkimuksen, tyttötutkimuksen, nuorisotutkimuksen ja kulttuurimaantieteen näkökulmia yhdistelemällä. Ensimmäisessä aineistontulkintaluvussa tarkastellaan tyttöyteen ja maineen rakentumiseen liittyvää ruumiillista merkityksenantoa pukeutumisen, seksuaalisuuden, tyttöjen ympärileikkausta koskevan asennemuutoksen ja seurustelun teemojen kautta. Toisessa luvussa keskitytään kaupunkitilan ja tyttöjen vapaa-ajanvieton sosiotilallisiin tulkintoihin sekä tyttöjen käytöstä kodin ulkopuolella määritteleviin ja mainetta rakentaviin puheisiin. Haastatellut arvostivat islamiin ja somaliperinteeseen liittyviä arvoja ja pitivät niitä oman käytöksensä ohjenuorina. Omanarvontunto, itsekontrolli ja vastuuntunto omista teoista liitettiin ”hyvään tyttöyteen”. Tyttöjen toimijuus ilmeni heihin kohdistuvien odotusten suuntaisena käyttäytymisenä ja näiden ihanteiden arvostamisena. Toimijuus näkyi myös tiettyjen tyttöihin ja poikiin kohdistuvien erilaisten odotusten kyseenalaistamisena ja joissakin tapauksissa vastoin odotuksia toimimisena. Turkua myös verrattiin somalityttöjen käytöksen osalta pääkaupunkiseutuun. Tässä vertailussa Turku nimettiin kulttuurisen jatkuvuuden, pääkaupunkiseutu kulttuurisen muutoksen paikaksi. Haastateltujen mukaan yhteisöllisiä tulkintoja tyttöjen käytöksestä tehtiin puheissa ja juoruissa, usein suhteessa havaintoihin suomalaistyttöjen käytöksestä. Tyttöjen arkeen nämä etniset ja moraaliset eroteot eivät kuitenkaan vaikuttaneet aina samalla tavoin, koska tulkinnat tyttärille sopivasta ja mahdollisesta käytöksestä voivat vaihdella perheiden välillä. Tutkimus tuo esille, että tytön hyvä maine on eräs perheen hyvinvointiin vaikuttavista tekijöistä. Somalityttöjen käytös on myös eräs yhteisöllinen peili, jota vasten tehdään laajempia tulkintoja somalikulttuurin ja uskonnollisten arvojen tilasta diasporassa. Liiallinen muutos tyttöjen käyttäytymisessä uhkasi yhteisöllistä jatkuvuutta ja uskonnolliskulttuuristen arvojen välittymistä seuraaville sukupolville. Laajasti ymmärrettynä ”hyvä tyttöys” ja hyvä maine oli onnistuneen kulttuurisen neuvottelun tulosta diasporassa. Se tarkoitti, että tyttö kiinnittyi somalialaiseen taustaansa ja sen välittämiin arvoihin, osallistuen samalla kuitenkin myös suomalaiseen yhteiskuntaan.

Designing new learning experiences? : exploring corporate E-learners’ self-regulated learning

The context of this study is corporate e-learning, with an explicit focus on how digital learning design can facilitate self-regulated learning (SRL). The field of e-learning is growing rapidly. An increasing number of corporations use digital technology and elearning for training their work force and customers. E-learning may offer economic benefits, as well as opportunities for interaction and communication that traditional teaching cannot provide. However, the evolving variety of digital learning contexts makes new demands on learners, requiring them to develop strategies to adapt and cope with novel learning tools. This study derives from the need to learn more about learning experiences in digital contexts in order to be able to design these properly for learning. The research question targets how the design of an e-learning course influences participants’ self-regulated learning actions and intentions. SRL involves learners’ ability to exercise agency in their learning. Micro-level SRL processes were targeted by exploring behaviour, cognition, and affect/motivation in relation to the design of the digital context. Two iterations of an e-learning course were tested on two groups of participants (N=17). However, the exploration of SRL extends beyond the educational design research perspective of comparing the effects of the changes to the course designs. The study was conducted in a laboratory with each participant individually. Multiple types of data were collected. However, the results presented in this thesis are based on screen observations (including eye tracking) and video-stimulated recall interviews. These data were integrated in order to achieve a broad perspective on SRL. The most essential change evident in the second course iteration was the addition of feedback during practice and the final test. Without feedback on actions there was an observable difference between those who were instruction-directed and those who were self-directed in manipulating the context and, thus, persisted whenever faced with problems. In the second course iteration, including the feedback, this kind of difference was not found. Feedback provided the tipping point for participants to regulate their learning by identifying their knowledge gaps and to explore the learning context in a targeted manner. Furthermore, the course content was consistently seen from a pragmatic perspective, which influenced the participants’ choice of actions, showing that real life relevance is an important need of corporate learners. This also relates to assessment and the consideration of its purpose in relation to participants’ work situation. The rigidity of the multiple choice questions, focusing on the memorisation of details, influenced the participants to adapt to an approach for surface learning. It also caused frustration in cases where the participants’ epistemic beliefs were incompatible with this kind of assessment style. Triggers of positive and negative emotions could be categorized into four levels: personal factors, instructional design of content, interface design of context, and technical solution. In summary, the key design choices for creating a positive learning experience involve feedback, flexibility, functionality, fun, and freedom. The design of the context impacts regulation of behaviour, cognition, as well as affect and motivation. The learners’ awareness of these areas of regulation in relation to learning in a specific context is their ability for design-based epistemic metareflection. I describe this metareflection as knowing how to manipulate the context behaviourally for maximum learning, being metacognitively aware of one’s learning process, and being aware of how emotions can be regulated to maintain volitional control of the learning situation. Attention needs to be paid to how the design of a digital learning context supports learners’ metareflective development as digital learners. Every digital context has its own affordances and constraints, which influence the possibilities for micro-level SRL processes. Empowering learners in developing their ability for design-based epistemic metareflection is, therefore, essential for building their digital literacy in relation to these affordances and constraints. It was evident that the implementation of e-learning in the workplace is not unproblematic and needs new ways of thinking about learning and how we create learning spaces. Digital contexts bring a new culture of learning that demands attitude change in how we value knowledge, measure it, define who owns it, and who creates it. Based on the results, I argue that digital solutions for corporate learning ought to be built as an integrated system that facilitates socio-cultural connectivism within the corporation. The focus needs to shift from designing static e-learning material to managing networks of social meaning negotiation as part of a holistic corporate learning ecology.

Affektitehdas. Työn rationalisoinnin historiallisia jatkumoita

Affektit, kapitalismi ja työn rationalisointi yhdistyvät toisiinsa erottamattomasti. Nykykeskusteluissa työstä ja työelämästä rationalisointi jaetaan usein tekniseen fordistiseen rationalisointiin ja sitä tunteellisempaan postfordistiseen rationalisointiin. Tämä tutkimus osoittaa, affektiivisen rationalisoinnin käsitteen kautta, että työn vanhat ja uudet tieteet asettuvat jatkumoon. Työn tieteissä tietoa työläisestä tuotetaan asettamalla ominaisuuksia aina uudelleen määriteltävään työläisen luokittuneeseen ja sukupuolittuneeseen affektiiviseen figuuriin. Tiedon tuottamisen näkökulmasta muun muassa tayloristiset työn tehostamisen fantasiat, ihmissuhdekoulukunnan ideologiat sekä uuden työn autonomiset järjestykset sisältävät yhtenäisiä piirteitä. Tutkimuksen pääkysymys on: miten affekteja rationalisoidaan työssä, työn tieteissä ja niiden kerrostumissa. Tutkimuksessa kysytään myös, miten affekti kiinnittää luokittuneet ja sukupuolittuneet subjektit työn rationalisoinnin aatteeseen ja millaisia mahdollisuuksia työläiseksi tulemiseen niissä tarjotaan. Kysymystä lähestytään monipuolisen aineiston ja lukuisten teemojen kautta. Aineistoina toimivat muun muassa rationalisoinnin klassikko-teokset, operaismo-vaikutteisen prekariaattiliikkeen pamfletit, ajatushautomoiden uuden työn visiot, self-help-teokset uranaisille sekä Helsingin Sanomien työelämäkeskustelut. Tutkimuksen monipuolista aineistoa lähiluetaan ja tulkitaan siihen luodun erityisen metodologian kautta, joka koostuu kolmesta osa-alueesta: historiallistaminen, paikantuminen ja figuurit. Kaksi ensimmäistä korostavat kontekstien ja position merkitystä tiedon tuotannossa, kolmas osoittaa tiedon tuottamisen valtasuhteita. Työn tieteiden visiot ideaalityöläisestä materialisoituvat figuurien kautta negaatioina kuvaten sitä, millainen ideaalityöläinen ei ole. Väitöskirja aineistoineen paikantuu Suomeen, mutta se osoittaa työn tieteiden ja affektiivisen rationalisoinnin globaaliutta sekä sidonnaisuutta Yhdysvaltoihin, sen yrityskulttuuriin ja esimerkiksi työtehotutkimuksiin Hawthornen elektroniikkatehtaalla vuosina 1924–1933. Väitöskirja tuo uusia näkökulmia nykykeskusteluun työstä, työläisistä, kapitalismista ja affekteista. Se osoittaa, että itsen tuntemisen ja kertomisen tieteitä, kuten psykologiaa, tarjotaan usein ratkaisuksi kapitalistisen tuotannon aiheuttamiin suuriin ja pieniin kurjuuksiin, vaikka terapeuttinen tunnekulttuuri itsessään on muodostunut osana rationalisoinnin ja kapitalismin ambivalentteja kehiä. Tutkimus myös muistuttaa, että työn järjestyksien keskiössä säilyy työläisen ja affektitehtaan konflikti silloinkin, kun fordistinen imperatiivi ”älä!” vaihtuu postfordistiseen kehotukseen ”tunne”.

Visual Customer Segmentation and Data Exploration with the Self-Organizing Map

Advancements in information technology have made it possible for organizations to gather and store vast amounts of data of their customers. Information stored in databases can be highly valuable for organizations. However, analyzing large databases has proven to be difficult in practice. For companies in the retail industry, customer intelligence can be used to identify profitable customers, their characteristics, and behavior. By clustering customers into homogeneous groups, companies can more effectively manage their customer base and target profitable customer segments. This thesis will study the use of the self-organizing map (SOM) as a method for analyzing large customer datasets, clustering customers, and discovering information about customer behavior. Aim of the thesis is to find out whether the SOM could be a practical tool for retail companies to analyze their customer data.

Business intelligence – enabling self-service: A case study in a global manufacturing company

Business intelligence (BI) is an information process that includes the activities and applications used to transform business data into valuable business information. Today’s enterprises are collecting detailed data which has increased the available business data drastically. In order to meet changing customer needs and gain competitive advantage businesses try to leverage this information. However, IT departments are struggling to meet the increased amount of reporting needs. Therefore, recent shift in the BI market has been towards empowering business users with self-service BI capabilities. The purpose of this study was to understand how self-service BI could help businesses to meet increased reporting demands. The research problem was approached with an empirical single case study. Qualitative data was gathered with a semi-structured, theme-based interview. The study found out that case company’s BI system was mostly used for group performance reporting. Ad-hoc and business user-driven information needs were mostly fulfilled with self-made tools and manual work. It was felt that necessary business information was not easily available. The concept of self-service BI was perceived to be helpful to meet such reporting needs. However, it was found out that the available data is often too complex for an average user to fully understand. The respondents felt that in order to self-service BI to work, the data has to be simplified and described in a way that it can be understood by the average business user. The results of the study suggest that BI programs struggle in meeting all the information needs of today’s businesses. The concept of self-service BI tries to resolve this problem by allowing users easy self-service access to necessary business information. However, business data is often complex and hard to understand. Self-serviced BI has to overcome this challenge before it can reach its potential benefits.

Quality of outsourced IT services in different degrees of offshoring

The Finnish IT service market can be described to be at a turning point. The clients are ever more interested on services delivered from offshore but certain issues keep them cautious. There is a lack of knowledge on what implications different degrees of offshoring have on service quality. Although there has been significant amount of research related to both service quality and offshoring, several questions are unanswered, terminology remains ambivalent and research findings are inconsistent. The study focuses on the interception of these two fields. The purpose of the study is to learn more about service quality in different degrees of offshoring. At the same time it aims to contribute in narrowing the research gaps. The degree of offshoring can be divided to three delivery modes: onshore, collaboration and offshore. The study takes a mixed method approach where the quantitative and qualitative phases are executed sequentially. First data was gathered from incident management system. Resolution time in different degrees of offshoring was analyzed with Kruskal-Wallis and Jonckheere-Terpstra tests. In addition, the compliance to Service Level Agreement (SLA) in different degrees of offshoring was examined with cross tabulation. The findings from the quantitative analysis suggested that the services with offshore delivery mode perform the best in terms of promptness and SLA compliance. However, several issues were found related to the data and for that reason, the findings should be considered with prudence. After the quantitative analysis, the study moved on to qualitative data collection and analysis. Four semi-structured interviews were held. The interviewees represented different organizational roles and had experiences from different delivery modes. Several themes were covered in the interviews, including: the concept of quality, the subjectivity or objectivity of service quality, expectations and prejudices towards offshore deliveries, quality produced in India, proactiveness of offshore resources, quality indicators and the scarcity of collaborative deliveries. Several conclusions can be made from the empirical research. Firstly, the quality in different delivery modes was found to be controversial topic. Secondly, in the collaborative delivery covered in the study, the way tasks and resources are allocated seem to cause issues. On the other hand inexperienced offshore resources are assigned to the delivery and on the other hand only routine tasks are assigned to the resources. This creates a self-enforcing loop that results in low motivation, low ownership and high employee turnover in offshore. Nevertheless, this issue is not characteristic only to collaborative deliveries but rather allocation of tasks and resources. Moreover, prejudices were identified to affect the perceived service quality in non-predictable way. The research also demonstrated that there is a need in focal company for further data gathering and analysis.

Expressing the self in postmodern travel consumption: a case study of students

The study approaches student travel from the perspective of postmodern consumption. The background is in the observation that the student travel market has a vast potential, but it is not necessarily capitalized upon to the extent it could. This might partly have to do with the peculiarities of postmodernity: consumption is characterized by unpredictability and abstract motives. The research questions are built around what constitutes student travel consumption and how can students be categorized according to motivation, behaviour and values. Also identity and expressiveness are present and it is evaluated, if travel services facilitate these background is the observation that the student travel market has a vast potential, but it is not necessarily capitalized upon to the extent it could be. This might partly have to do with the peculiarities of postmodernity: consumption is characterized by unpredictability and abstract motives. The research questions are built around what constitutes student travel consumption and how can students be categorized according to motivation, behaviour and values. Also identity and expressiveness are present and it is evaluated whether travel services facilitate these constructs. The topic is approached by discovering the key concepts such as self-identity. This was done in order to create survey questions that reflect the underlying theories. The survey was sent to chosen student groups of Turku School of Economics. The data was analyzed using statistical methods, mainly principal component analysis, in order to categorize students’ motives and behaviour into distinct profiles. The findings indicate that students have a high level of awareness in their travel consumption choices. Travel services seem to facilitate identity and lifestyle expressiveness, one central dimension of postmodernity. Psychographics such as motivation seem to work well as a segmentation criteria when it comes to the student traveler market. Travel offers students an opportunity for relaxation, escape, enjoyment and gaining new experiences and social contacts. Furthermore, the enjoyment of the travel experience extends to the pre- and post-trip time.

Perceived modifiability of self-blame attributions for negative life events : implications for well-being /

Research suggests that self-blame attributions are important in the process of adjustment to negative life events. Much of the research originates from JanofTBulman's (1979) theory regarding behavioural and characterological self-blame. She argued that attributing negative events to one's behaviour is adaptive because behavioural self-blame involves attributions to a modifiable source, which implies that a similar event can be avoided in the future. In contrast, attributing negative events to one's character is believed to be maladaptive because character is seen as relatively stable and unmodifiable. Unfortunately, the empirical literature does not show consistent relations between these two types of self-blame attributions and well-being as predicted by Janoff-Bulman. For this thesis, I proposed that one reason for this inconsistency is that Janoff-Bulman's assumption about the perceived modifiability of behavioural versus characterological causes is incorrect — people often dlo perceive character (as well as behaviour) to be modifiable. Sixty-two participants completed a questionnaire regarding a recent negative life event and its impact on their well-being. Consistent with my argument, I found that both behavioural and characterological self-blame attributions following a negative life event were seen as modifiable. As hypothesized, perceived modifiability of causes v^as related to well-being. For example, overall modifiability was related to greater coping efficacy, less social dysfunction, less severe depression, and greater positive affect; however. contrary to predictions, the relation between perceived modifiability of causes and wellbeing was not mediated by the perception that similar events could be avoided in the future. Individual differences in attributional style were also assessed in this study. An attributional style that tended to be more internal, stable, and specific was related to wellbeing as expected; however, neither the perceived modifiability of blame attributions nor the perceived avoidability of similar future events mediated this relation. Implications for professionals dealing with trauma victims and potential directions for future research are discussed.

Registered nurses' perceptions of factors impacting on their continuing education /

This qualitative study examined the effects of hospital restructuring on a group of nurses at a community hospital. Eleven nurses were asked questions in order to gain insight into their experience in this situation. Ten of these participants were female, and one was male. The intent was to gather information about how restructuring has affected their lives, including, their motivational factors and barriers to participation in continuing education, and their descriptions of their workplace environment. Audiotaped interviews were conducted on two occasions to obtain this data. Emergent themes included the nurses' comments about continuing education, motivational factors, barriers that included geography and time, reactions of co-workers, restructuring, the College of Nurses' Quality Assurance Program including peer feedback, and performance appraisals. The literature review compares the barriers and motivational factors to the previous research findings. Thus, this study gave voice to the experience of this group of nurses, working in a healthcare setting that is involved in restructuring. This information is important to the healthcare system, since many areas are involved in restructuring. The whole process, if it is to be successful, depends on the frontline workers, namely the nurses. Thus, if there is anything to be learned from this group of people, that could be used to improve this progression, everyone would benefit from this information, were it to be implemented. Everyone is a stakeholder in the quality of healthcare in our province. The frontline workers are the ones that hold the vantage point to be able to provide suggestions for the changes needed to successful. These nurses are not just motivated by work issues however, and educating them and motivating them will also improve the care provided through increased knowledge and enhanced self-esteem.
