Charting Our Own Course: Today’s Challenges, Tomorrow’s Opportunities, December 2008

The Office of Energy Independence presents Iowa’s second annual energy independence plan, which highlights accomplishments achieved thus far and makes recommendations for the coming year. This plan shows that Iowa has made significant progress in building the foundation for reaching energy independence in just the past year. Continued investment and further efforts will enable Iowa to push toward even greater advances, while creating new jobs and diversifying local economies. With those aims in mind, the state has been investing extensively in the new energy economy. One important example is the Iowa Power Fund, an annual appropriation from the Iowa General Assembly administered by the Office of Energy Independence. In less than one year, the Office has received more than 160 project applications totaling more than $308 million in requests. The projects approved thus far will help advance Iowa’s wind and solar industries, foster new energy efficiency practices, and develop the bio fuels industry for a more economically and environmentally sustainable future. Iowa’s position as a leader in the new energy economy is dependent on the success of the Power Fund, and on the success of this plan. This plan clearly states that Iowa must boldly pursue a strong position in the emerging energy economy worldwide.

Knowledge management: uncovering risky gaps underlying the criticisms and moving to another perspective

The comments related to the sustainability of knowledge management (KM) have shown signs that it possibly can be a discourse which determines a quick style, but otherwise have also allowed the building of a better understanding about the limits and weaknesses of the knowlege management. In addition to the criticisms, the conceptual bases of knowledge management have been undermined by a contradictory combination of paradigms; there are also contradictions between the theoretical perspective jubjacent to the knwoledge management and its operationality. As a way of minimizing the possibility that the knowledge management may be turned into an umbrella concept and fail, it is suggested that its approaches embody a more interpretative perspective, taking up the role of an instrument which enables and facilitates the processes and practices in building up knowledge and information, enhancing their focus on the support to the establishment of human competences in order to deal intelligently with the present overcharge of information resources and need for building up information in the organizations.

Recycled Asphalt Pavements - Kossuth County Iowa, HR-176, 1975

Kossuth County is located in North Central Iowa bordering on the State of Minnesota. It is the largest county in Iowa consisting of 28 congressional townships. The population of the county is 23,000 of which 11,000 people live in the rural area. There are 13 towns located in the county with the county seat, Algona, being the largest with a population of 6,100. Major industry of the area is grain farming with some beef and hog production. Naturally, where there is good grain farm land it follows that there is poor soil available for road construction and pavements. However, below the 3 to 4 feet of good farm land of Kossuth there is present a good grade of clay soil which does make an adequate base for surfacing when placed and compacted on top of the roadbed. As early as 1950, the then Kossuth County Engineer, H.M. Smith, embarked on a program of stage construction in building new grades and pavements. The goal of his program was primarily to conserve the county's rapidly dwindling supply of surfacing materials, and also, to realize the side effects of providing smooth and dustless roads for the public. Engineer Smith was fully aware of the poor soils that existed for road construction, but he also knew about the good clay that lay below the farm soil. Consequently, in his grading program he insisted that road ditches be dug deep enough to allow the good clay soil to be compacted on top of the roadbed. The presence of the compacted clay on top of the road resulted in a briding affect over the farm soil. The stage construction program satisfied the objectives of aggregate construction and dust control but did generate other problems which we are now trying to solve as economically as possible.

08018-010 Walnut Creek Final Report

In 2004 Walnut Creek was placed on the 303d list of impaired water bodies for lack of aquatic life with biological causes. Sediment from farmland as well as the stream banks was listed as the most likely stressor. In response to this listing a preliminary watershed assessment was completed by the six counties which have land in the Walnut Creek watershed. Walnut Creek flows through portions of Shelby, Pottawattamie, Montgomery, Mills, Page, and Fremont Counties before reaching its confluence with the West Nishnabotna River. The preliminary study assessed resource concerns and evaluated anticipated landowner participation levels for the six Huc 12 sub-watersheds which divide the Walnut Creek basin. These preliminary assessments revealed a priority sub-watershed which lies between US Hwy 6 and Hwy 34. A development grant was then funded by the Division of Soil Conservation to conduct a detailed assessment of this area. The detailed assessment involved an assessment of the uplands as well as the stream itself. A better understanding of the resource concerns was gained through the assessment, allowing for a comprehensive watershed plan to be developed. A variety of best management practices will be necessary for our project to be a success, many of which will be funded by other sources besides the WIRB. This grant is the first request for funding submitted by the East Pottawattamie and Montgomery SWCDs’. This grant will serve as the first critical step in building what is destined to be a true watershed success story.

Limitations and information needs for engineered nanomaterial-specific exposure estimation and scenarios: recommendations for improved reporting practices

The aim of this paper is to describe the process and challenges in building exposure scenarios for engineered nanomaterials (ENM), using an exposure scenario format similar to that used for the European Chemicals regulation (REACH). Over 60 exposure scenarios were developed based on information from publicly available sources (literature, books, and reports), publicly available exposure estimation models, occupational sampling campaign data from partnering institutions, and industrial partners regarding their own facilities. The primary focus was on carbon-based nanomaterials, nano-silver (nano-Ag) and nano-titanium dioxide (nano-TiO2), and included occupational and consumer uses of these materials with consideration of the associated environmental release. The process of building exposure scenarios illustrated the availability and limitations of existing information and exposure assessment tools for characterizing exposure to ENM, particularly as it relates to risk assessment. This article describes the gaps in the information reviewed, recommends future areas of ENM exposure research, and proposes types of information that should, at a minimum, be included when reporting the results of such research, so that the information is useful in a wider context.

Total Cost of Transportation Analysis of Road and Highway Issues, HR-388, 2002

In the administration, planning, design, and maintenance of road systems, transportation professionals often need to choose between alternatives, justify decisions, evaluate tradeoffs, determine how much to spend, set priorities, assess how well the network meets traveler needs, and communicate the basis for their actions to others. A variety of technical guidelines, tools, and methods have been developed to help with these activities. Such work aids include design criteria guidelines, design exception analysis methods, needs studies, revenue allocation schemes, regional planning guides, designation of minimum standards, sufficiency ratings, management systems, point based systems to determine eligibility for paving, functional classification, and bridge ratings. While such tools play valuable roles, they also manifest a number of deficiencies and are poorly integrated. Design guides tell what solutions MAY be used, they aren't oriented towards helping find which one SHOULD be used. Design exception methods help justify deviation from design guide requirements but omit consideration of important factors. Resource distribution is too often based on dividing up what's available rather than helping determine how much should be spent. Point systems serve well as procedural tools but are employed primarily to justify decisions that have already been made. In addition, the tools aren't very scalable: a system level method of analysis seldom works at the project level and vice versa. In conjunction with the issues cited above, the operation and financing of the road and highway system is often the subject of criticisms that raise fundamental questions: What is the best way to determine how much money should be spent on a city or a county's road network? Is the size and quality of the rural road system appropriate? Is too much or too little money spent on road work? What parts of the system should be upgraded and in what sequence? Do truckers receive a hidden subsidy from other motorists? Do transportation professions evaluate road situations from too narrow of a perspective? In considering the issues and questions the author concluded that it would be of value if one could identify and develop a new method that would overcome the shortcomings of existing methods, be scalable, be capable of being understood by the general public, and utilize a broad viewpoint. After trying out a number of concepts, it appeared that a good approach would be to view the road network as a sub-component of a much larger system that also includes vehicles, people, goods-in-transit, and all the ancillary items needed to make the system function. Highway investment decisions could then be made on the basis of how they affect the total cost of operating the total system. A concept, named the "Total Cost of Transportation" method, was then developed and tested. The concept rests on four key principles: 1) that roads are but one sub-system of a much larger 'Road Based Transportation System', 2) that the size and activity level of the overall system are determined by market forces, 3) that the sum of everything expended, consumed, given up, or permanently reserved in building the system and generating the activity that results from the market forces represents the total cost of transportation, and 4) that the economic purpose of making road improvements is to minimize that total cost. To test the practical value of the theory, a special database and spreadsheet model of Iowa's county road network was developed. This involved creating a physical model to represent the size, characteristics, activity levels, and the rates at which the activities take place, developing a companion economic cost model, then using the two in tandem to explore a variety of issues. Ultimately, the theory and model proved capable of being used in full system, partial system, single segment, project, and general design guide levels of analysis. The method appeared to be capable of remedying many of the existing work method defects and to answer society's transportation questions from a new perspective.

Tapping the innovation potential of corporate engagement with stakeholders

Summary This dissertation explores how stakeholder dialogue influences corporate processes, and speculates about the potential of this phenomenon - particularly with actors, like non-governmental organizations (NGOs) and other representatives of civil society, which have received growing attention against a backdrop of increasing globalisation and which have often been cast in an adversarial light by firms - as a source of teaming and a spark for innovation in the firm. The study is set within the context of the introduction of genetically-modified organisms (GMOs) in Europe. Its significance lies in the fact that scientific developments and new technologies are being generated at an unprecedented rate in an era where civil society is becoming more informed, more reflexive, and more active in facilitating or blocking such new developments, which could have the potential to trigger widespread changes in economies, attitudes, and lifestyles, and address global problems like poverty, hunger, climate change, and environmental degradation. In the 1990s, companies using biotechnology to develop and offer novel products began to experience increasing pressure from civil society to disclose information about the risks associated with the use of biotechnology and GMOs, in particular. Although no harmful effects for humans or the environment have been factually demonstrated even to date (2008), this technology remains highly-contested and its introduction in Europe catalysed major companies to invest significant financial and human resources in stakeholder dialogue. A relatively new phenomenon at the time, with little theoretical backing, dialogue was seen to reflect a move towards greater engagement with stakeholders, commonly defined as those "individuals or groups with which. business interacts who have a 'stake', or vested interest in the firm" (Carroll, 1993:22) with whom firms are seen to be inextricably embedded (Andriof & Waddock, 2002). Regarding the organisation of this dissertation, Chapter 1 (Introduction) describes the context of the study, elaborates its significance for academics and business practitioners as an empirical work embedded in a sector at the heart of the debate on corporate social responsibility (CSR). Chapter 2 (Literature Review) traces the roots and evolution of CSR, drawing on Stakeholder Theory, Institutional Theory, Resource Dependence Theory, and Organisational Learning to establish what has already been developed in the literature regarding the stakeholder concept, motivations for engagement with stakeholders, the corporate response to external constituencies, and outcomes for the firm in terms of organisational learning and change. I used this review of the literature to guide my inquiry and to develop the key constructs through which I viewed the empirical data that was gathered. In this respect, concepts related to how the firm views itself (as a victim, follower, leader), how stakeholders are viewed (as a source of pressure and/or threat; as an asset: current and future), corporate responses (in the form of buffering, bridging, boundary redefinition), and types of organisational teaming (single-loop, double-loop, triple-loop) and change (first order, second order, third order) were particularly important in building the key constructs of the conceptual model that emerged from the analysis of the data. Chapter 3 (Methodology) describes the methodology that was used to conduct the study, affirms the appropriateness of the case study method in addressing the research question, and describes the procedures for collecting and analysing the data. Data collection took place in two phases -extending from August 1999 to October 2000, and from May to December 2001, which functioned as `snapshots' in time of the three companies under study. The data was systematically analysed and coded using ATLAS/ti, a qualitative data analysis tool, which enabled me to sort, organise, and reduce the data into a manageable form. Chapter 4 (Data Analysis) contains the three cases that were developed (anonymised as Pioneer, Helvetica, and Viking). Each case is presented in its entirety (constituting a `within case' analysis), followed by a 'cross-case' analysis, backed up by extensive verbatim evidence. Chapter 5 presents the research findings, outlines the study's limitations, describes managerial implications, and offers suggestions for where more research could elaborate the conceptual model developed through this study, as well as suggestions for additional research in areas where managerial implications were outlined. References and Appendices are included at the end. This dissertation results in the construction and description of a conceptual model, grounded in the empirical data and tied to existing literature, which portrays a set of elements and relationships deemed important for understanding the impact of stakeholder engagement for firms in terms of organisational learning and change. This model suggests that corporate perceptions about the nature of stakeholder influence the perceived value of stakeholder contributions. When stakeholders are primarily viewed as a source of pressure or threat, firms tend to adopt a reactive/defensive posture in an effort to manage stakeholders and protect the firm from sources of outside pressure -behaviour consistent with Resource Dependence Theory, which suggests that firms try to get control over extemal threats by focussing on the relevant stakeholders on whom they depend for critical resources, and try to reverse the control potentially exerted by extemal constituencies by trying to influence and manipulate these valuable stakeholders. In situations where stakeholders are viewed as a current strategic asset, firms tend to adopt a proactive/offensive posture in an effort to tap stakeholder contributions and connect the organisation to its environment - behaviour consistent with Institutional Theory, which suggests that firms try to ensure the continuing license to operate by internalising external expectations. In instances where stakeholders are viewed as a source of future value, firms tend to adopt an interactive/innovative posture in an effort to reduce or widen the embedded system and bring stakeholders into systems of innovation and feedback -behaviour consistent with the literature on Organisational Learning, which suggests that firms can learn how to optimize their performance as they develop systems and structures that are more adaptable and responsive to change The conceptual model moreover suggests that the perceived value of stakeholder contribution drives corporate aims for engagement, which can be usefully categorised as dialogue intentions spanning a continuum running from low-level to high-level to very-high level. This study suggests that activities aimed at disarming critical stakeholders (`manipulation') providing guidance and correcting misinformation (`education'), being transparent about corporate activities and policies (`information'), alleviating stakeholder concerns (`placation'), and accessing stakeholder opinion ('consultation') represent low-level dialogue intentions and are experienced by stakeholders as asymmetrical, persuasive, compliance-gaining activities that are not in line with `true' dialogue. This study also finds evidence that activities aimed at redistributing power ('partnership'), involving stakeholders in internal corporate processes (`participation'), and demonstrating corporate responsibility (`stewardship') reflect high-level dialogue intentions. This study additionally finds evidence that building and sustaining high-quality, trusted relationships which can meaningfully influence organisational policies incline a firm towards the type of interactive, proactive processes that underpin the development of sustainable corporate strategies. Dialogue intentions are related to type of corporate response: low-level intentions can lead to buffering strategies; high-level intentions can underpin bridging strategies; very high-level intentions can incline a firm towards boundary redefinition. The nature of corporate response (which encapsulates a firm's posture towards stakeholders, demonstrated by the level of dialogue intention and the firm's strategy for dealing with stakeholders) favours the type of learning and change experienced by the organisation. This study indicates that buffering strategies, where the firm attempts to protect itself against external influences and cant' out its existing strategy, typically lead to single-loop learning, whereby the firm teams how to perform better within its existing paradigm and at most, improves the performance of the established system - an outcome associated with first-order change. Bridging responses, where the firm adapts organisational activities to meet external expectations, typically leads a firm to acquire new behavioural capacities characteristic of double-loop learning, whereby insights and understanding are uncovered that are fundamentally different from existing knowledge and where stakeholders are brought into problem-solving conversations that enable them to influence corporate decision-making to address shortcomings in the system - an outcome associated with second-order change. Boundary redefinition suggests that the firm engages in triple-loop learning, where the firm changes relations with stakeholders in profound ways, considers problems from a whole-system perspective, examining the deep structures that sustain the system, producing innovation to address chronic problems and develop new opportunities - an outcome associated with third-order change. This study supports earlier theoretical and empirical studies {e.g. Weick's (1979, 1985) work on self-enactment; Maitlis & Lawrence's (2007) and Maitlis' (2005) work and Weick et al's (2005) work on sensegiving and sensemaking in organisations; Brickson's (2005, 2007) and Scott & Lane's (2000) work on organisational identity orientation}, which indicate that corporate self-perception is a key underlying factor driving the dynamics of organisational teaming and change. Such theorizing has important implications for managerial practice; namely, that a company which perceives itself as a 'victim' may be highly inclined to view stakeholders as a source of negative influence, and would therefore be potentially unable to benefit from the positive influence of engagement. Such a selfperception can blind the firm from seeing stakeholders in a more positive, contributing light, which suggests that such firms may not be inclined to embrace external sources of innovation and teaming, as they are focussed on protecting the firm against disturbing environmental influences (through buffering), and remain more likely to perform better within an existing paradigm (single-loop teaming). By contrast, a company that perceives itself as a 'leader' may be highly inclined to view stakeholders as a source of positive influence. On the downside, such a firm might have difficulty distinguishing when stakeholder contributions are less pertinent as it is deliberately more open to elements in operating environment (including stakeholders) as potential sources of learning and change, as the firm is oriented towards creating space for fundamental change (through boundary redefinition), opening issues to entirely new ways of thinking and addressing issues from whole-system perspective. A significant implication of this study is that potentially only those companies who see themselves as a leader are ultimately able to tap the innovation potential of stakeholder dialogue.

Selvitys yliopistorakennuksen energiatehokkuudesta

Rakennusten energiatehokkuusdirektiivi astui voimaan vuonna 2003. Yksi direktiivinkeskeisimmistä kohdista on energiatodistuksen hankkiminen silloin kun rakennusta tai sen osaa myydään tai vuokrataan. Kiinteistön omistaja voi hankkia energiatodistuksen joko erillisenä todistuksena, isännöitsijäntodistuksen osana tai katselmuksen yhteydessä. Tässä työssä verrataan jo olemassa olevaa katselmusmenettelyä erilliseen energiatodistukseen ja energiatodistuksen myöntämiseen isännöitsijätodistuksen yhteydessä case-kohteen kautta arvioituna. Vertailun suorittamiseksi tehtiin osana diplomityötä energiakatselmus Lappeenrannan teknillisen yliopiston rakennusvaiheesta 7. Energiakatselmukseen verrattuna energiatodistus on huomattavasti suppeampi selvitys rakennuksen energiankulutuksesta. Arvioitu energiankulutuksen säästöpotentiaali energiatodistuksessa oli noin puolet energiakatselmuksessa löydetyistä, kustannusten ollessa huomattavasti alhaisemmat. Erillisenä osana työssä käsitellään tilaustehojen tarkistusta Lappeenrannan teknillisen yliopiston rakennuskannasta. Rakennusvaiheen 7 tilausteho oli oikeansuuruinen, muiden rakennusvaiheiden osalta tilaustehojen uudelleen tarkastamista kannattaa harkita.

Kumppanuusyrityksen jakelurakenne rakentamisen toimitusketjussa - Case: Starkki Oy Ab

Tutkimuksen tavoitteena on selvittää tarvitseeko Starkki Oy Ab keskusvarastotoimintoja rakennustyömaan toimitusketjussa. Tutkimuksen teoriaosa esittelee reagoivan toimitusketjun hallinnan menetelmiä ja jakelun merkitystä toimitusketjussa. Lisäksi teoriaosassa esitellään kumppanuus-ajattelun perusteita. Empiriaosassa esitellään kohdeyritys, rakennustyömaan logistiikkaa tällä hetkellä ja pohditaan kolmea erilaista yrityksen jakelurakennetta. Tutkimus on kuvaileva. Rakennustyömaan logistiikan voidaantodeta jäävän helposti materiaalitoimittajien vastuulle. Vaikka materiaalitoimittajat pysyvätkin yleensä sovitussa aikataulussa, ei rakennustyömaa itsessään siinä välttämättä onnistu. Tämä johtaa rakentamisen logistiikan hallitsemattomuuteen ja rakentamisen tehokkuuden heikkenemiseen. Ongelma voidaan kuitenkin välttäätehokkaalla informaation jakamisella ja rakennustyömaan toimitusketjun läpi ulottuvalla yhteistyöllä.

Balanced Scorecardin implementointi ja käytön nykytila Suomessa

Lisääntynyt Balanced Scorecardin käyttö herätti kiinnostuksen tutkia, mistä BSC:ssä oli oikein kysymys. Epäonnistumiset BSC-projekteissa vaikuttivat siihen, että haluttiin tutkia, mikä nykyisissä projektimalleissa oli vikana. Kirjallisuudessa on esitetty useita BSC:n käyttöönoton projektimalleja, joista tunnetuin on Kaplanin ja Nortonin kehittämä malli. Alun perin kyseessä oli varsin operatiivinen suoritusmittaristo, jonka tavoitteena oli nostaa ei-taloudelliset mittarit taloudellisten mittareiden rinnalle. Sittemmin lähestymistapa onlaajentunut strategiapohjaiseksi johtamisen järjestelmäksi, mutta mallin rakentamisessa on vielä puutteita. Havaitut puutteet BSC-projektimalleissa loivat tarpeen uuden mallin kehittämiselle. Tutkimuksen tavoitteena oli kehittää suomalaisten yritysjohtajien ja alan asiantuntijoiden avulla BSC-projektimalli, jota käyttämällä yritykset voisivat menestyksekkäämmin toteuttaa BSC-projektinsa. Lisäksi tavoitteena oli selvittää BSC:n käytön nykytila Suomen 500 suurimmassa yrityksessä. Tutkimuksessa haluttiin myös hankkia tietoa siitä, miksi yritykset olivat lähteneet BSC-projektiin, mitkä tekijät vaikuttivat BSC-projektin onnistumiseen jamitä muutoksia yritykset olivat tehneet BSC:n käytännön kokemuksen pohjalta. Tutkimuksen teoriaosassa tarkasteltiin yrityksen strategista suunnittelua ja johtamista, yrityksen johtamisessa käytettyjä ohjausjärjestelmiä, toiminnan kehittämistä ja BSC-projektien toteuttamista. Tutkimuksen empiriisessä osassa kehitettiinkymmenvaiheinen BSC-projektin toteuttamismalli. Se tehtiin tutustumalla 15 konsultointiyrityksen tapaan toteuttaa BSC-projekti ja paneutumalla 50 yrityksen BSC-projektista saamiin kokemuksiin. Kehitettyä mallia testattiin Tulikivi-casessa,ja sitä arvioitiin kyselytutkimuksessa ja työistunnossa. Kyselytutkimuksen mukaan ensimmäiset suomalaiset yritykset aloittivat BSC:n käytön vuonna 1995. Vuonna1996 käyttö yleistyi jonkin verran, ja vuosia 1997 ja 1998 voidaan Suomessa kutsua BSC:n läpimurtovuosiksi. Vastanneista yrityksistä 23,2 % ilmoitti käyttävänsä BSC:tä. Yrityksistä 14,8 % oli ottamassa sitä käyttöön, ja 19,2 % harkitsi käyttöönottamista. Yritykset olivat lähteneet BSC-projektiin mm. paremman ohjausjärjestelmän, toiminnan tehostamisen ja muutoksen aikaansaamisen toivossa. BSC-projektin onnistumisen tärkeimpinä tekijöinä pidettiin johdon sitoutumista hankkeeseen, mittariston kytkeytymistä strategiaan ja mittareiden selkeyttä. BSC:n nähtiin vaikuttaneen yrityksissä eniten liiketoiminnan kokonaisuuden ymmärtämiseen, strategian toteutumiseen ja ei-taloudellisten asioiden seurantaan. Yrityksissä olimuutettu toimintaa mm. niin, että se suuntautuisi enemmän asiakkaisiin ja tulevaisuuteen. Tulevaisuudessa BSC:llä uskottiin olevan suurimmat vaikutukset kokonaisvaltaiseen ja strategiseen johtamiseen sekä strategian toteutumisen seurantaan. Kyselytutkimuksen perusteella voitiin osoittaa, että suuret yritykset käyttävät BSC:tä enemmän kuin pienet yritykset. Myös alueellisia eroja on: pääkaupunkiseudulla BSC:tä käytetään enemmän kuin muualla maassa. Mitä kannattavammaksi kyselyyn vastaaja arvioi yrityksensä, sitä parempana se piti tässä tutkimuksessa kehitettyä BSC-projektimallia verrattuna Kaplanin ja Nortonin kehittämään BSC-projektimalliin. BSC-projekti on niin kokonaisvaltainen, että sen onnistuminen edellyttää koko henkilöstön osallistuvan siihen. Ylimmän johdon aito sitoutuminen on välttämätöntä, jotta BSC-projekti saa riittävästi resursseja. Projektissa visio jastrategiat puretaan käytännön toimiksi, joten ilman ylimmän johdon mukanaoloa projektilla ei ole asiakasta. Keskijohto ja henkilöstö toteuttavat laaditut strategiat, jolloin heidän panoksensa on erittäin merkittävä projektin onnistumiseksi. Henkilöstö pitää saada osallistumaan mittaristotyöhön, jotta he sitoutuisivat asetettuihin tavoitteisiin. Ellei henkilöstöä saada mukaan, mittaristo jää helposti ylimmän johdon työkaluksi. Tällöin strategian toteuttaminen koko organisaatiossa on hyvin työlästä, jopa mahdotonta. Mittariston pitää olla strategialähtöinen, eikä se saa olla liian monimutkainen. Mitä alemmalle tasolle organisaatiossamennään, sitä yksinkertaisempi mittariston pitää olla. Ylimmillä tasoilla mittareita voi olla kahdeksasta kahteentoista, mutta alemmilla tasoilla niitä on oltava hieman vähemmän. Projektin nopea läpivienti yrityksessä ei saa olla itsetarkoitus, mutta nopeasti saadut konkreettiset tulokset auttavat, että projekti saa resursseja ja mahdollistavat palautteen saamisen ja oppimisen. Kerralla ei BSC:täsaada täydellisesti toimivaksi, vaan se on oppimisprosessi, joka mahdollistaa syvällisemmän strategian toteuttamiseen. Tässä tutkimuksessa kehitetty BSC-projektin toteuttamismalli perustuu kymmenien asiantuntijoiden kokemuksiin ja näkemyksiin BSC-projektin toteuttamisesta. Kyselytutkimuksesta, työistunnosta ja Tulikivi-casesta saadut tulokset osoittavat, että kehitetyn mallin avulla yrityksillä on entistä paremmat mahdollisuudet saada BSC-projekti onnistumaan. Näin tutkimuksen päätavoite saavutettiin. Muut tavoitteet saavutettiin kyselytutkimuksen tulosten avulla.

Intervention de la pensée représentative de futurs enseignant-e-s dans leurs prises de position envers l'intégration scolaire

In the past two decades, international recommendations have made inclusive education a priority issue. Many countries have adopted school policies inciting players to question their representations about the duties and purposes of schooling and their role therein. In Switzerland, a new national and cantonal framework defines the integration of students with disabilities or special educational needs in the regular classroom as a priority. However, progress in this area is modest and many researchers are left wondering how teachers could be better prepared to meet the special needs of some students. Initial training is thus seen as essential in bringing pre-service teachers to develop open attitudes toward students with disabilities or special educational needs. While many studies have examined the role of training in building professional attitudes, very few deal with teacher representations of inclusive education, let alone those of future teachers. Our research focuses on two samples of pre-service teachers in the beginning, middle or end of their initial training. 261 pre-service teachers for primary education and 212 pre-service teachers for secondaiy education are involved in the study. The research aims to highlight the role of their representative thinking in building their attitudes towards inclusive education. Our results show that objectification remains essentialist and focuses on the prototypes of the most publicized disabilities. They also showed the weakness of the training system as perceived by future teachers. Even though they have maintained or strengthened positive attitudes towards integration, most leave their training with a reinforced sense of apprehension when faced with the disabilities or special educational needs that they expect to encounter in their future work. Although pre-service teachers consider their training insufficient, it nevertheless positively influences their attitudes toward integration. In particular, greater internship practice, however modest it may be, has a significant effect on attitudes of future teachers by increasing their perception of competence and confidence. -- Ces deux dernières décennies, les recommandations internationales ont fait de l'inclusion scolaire une thématique prioritaire. De nombreux pays ont adopté des politiques scolaires obligeant les acteurs scolaires à interroger leurs représentations des missions de l'école et leur rôle au sein de celle-ci. En Suisse, un nouveau cadre national et cantonal a défini comme prioritaire l'intégration dans l'école ordinaire des élèves en situation de handicap ou ayant des besoins éducatifs particuliers. Or, les avancées en la matière restent modestes et de nombreux chercheurs se questionnent sur la manière dont les enseignant-e-s pourraient être mieux préparés à répondre aux besoins éducatifs particuliers de certains élèves. La formation initiale est ainsi perçue comme essentielle pour amener les futurs enseignant-e-s pour développer des attitudes ouvertes envers les élèves en situation de handicap ou ayant des besoins éducatifs particuliers. Si beaucoup d'études portent sur le rôle de la formation dans la construction d'attitudes professionnelles, très peu traitent des représentations des enseignant-e-s à l'égard de l'intégration scolaire et encore moins de celles des futurs enseignant-e-s. Notre recherche porte sur deux populations de futurs enseignant-e-s en début, au milieu ou en fin de formation. Elles sont composées respectivement de 261 étudiant-e-s se destinant à l'enseignement primaire et de 212 étudiant-e-s se destinant à l'enseignement secondaire. La recherche vise à mettre en évidence l'intervention de leur pensée représentative dans leurs prises de position envers l'intégration scolaire. Nos résultats montrent que l'objectivation reste essentialiste et se focalise sur les prototypes de situations de handicap les plus médiatisés. Nos résultats font également fait apparaître la faiblesse du dispositif de formation tel que perçu les futurs enseignant-e-s. Quand bien même ont-ils conservé ou renforcé des attitudes favorables à l'intégration, ils quittent pour la plupart leur formation avec une appréhension renforcée à l'égard des situations de handicap ou de besoins éducatifs particuliers qu'ils s'attendent à rencontrer dans leur future pratique. Bien que la formation soit jugée insuffisante par les étudiant-e-s, elle oriente néanmoins favorablement leurs prises de position envers l'intégration des élèves concernés. En particulier, une plus grande pratique de stage, si modeste soit-elle, a un effet important sur ces prises de position par l'augmentation du sentiment de compétence et la perception d'assurance des futurs enseignant-e-s.

Polychlorinated and polybrominated biphenyls

This volume of the IARC Monographs provides evaluations of the carcinogenicity of polychlorinated biphenyls and polybrominated biphenyls. Polychlorinated biphenyls are a class of aromatic compounds comprising 209 congeners, each containing 1 to 10 chlorine atoms attached to a biphenyl nucleus. Technical products, which were manufactured to obtain a certain degree of chlorination, are mixtures of numerous congeners. These products were widely used as dielectric fluid in capacitors and transformers, and to a lesser extent in building materials. Although their production and use has been banned in most countries, these compounds are ubiquitous environmental pollutants, including in polar regions and the deep ocean, because they are persistent and bioaccumulate. Worldwide monitoring programmes have shown that polychlorinated biphenyls are present in most samples of human milk. An IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans of polychlorinated biphenyls, of the subclass of dioxinlike polychlorinated biphenyls, and of polybrominated biphenyls.

Fundamentos de un programa de tutoría entre iguales en los estudios universitarios de las artes

[spa]En este artículo, se presenta el programa de tutoría entre iguales implantado por el Observatorio sobre la Didáctica de las Artes (ODAS, Universidad de Barcelona) en la Facultad de Bellas Artes durante el curso académico 2010-2011. Sin embargo, en la exposición de su finalidad, objetivos y proceso de implantación, se ha buscado que la descripción y comentario de las particularidades de esta experiencia incorporara también una reflexión más general sobre algunos de los puntos clave de la tutoría entre iguales. En el plano teórico, y a partir de las ideas de Lave y Wenger, el artículo defiende la importancia de la teoría entre iguales en la construcción de la identidad del estudiante como uno de los ejes de la mejora de sus aprendizajes y de su participación en la institución educativa.

Virtauslaskentaa ja energia-analyysiä hyödyntävä huoneilman lämpöolosuhteiden simulointimalli

Huonetilojen lämpöolosuhteiden hallinta on tärkeä osa talotekniikan suunnittelua. Tavallisesti huonetilan lämpöolosuhteita mallinnetaan menetelmillä, joissa lämpödynamiikkaa lasketaan huoneilmassa yhdessä laskentapisteessä ja rakenteissa seinäkohtaisesti. Tarkastelun kohteena on yleensä vain huoneilman lämpötila. Tämän diplomityön tavoitteena oli kehittää huoneilman lämpöolosuhteiden simulointimalli, jossa rakenteiden lämpödynamiikka lasketaan epästationaarisesti energia-analyysilaskennalla ja huoneilman virtauskenttä mallinnetaan valittuna ajanhetkenä stationaarisesti virtauslaskennalla. Tällöin virtauskentälle saadaan jakaumat suunnittelun kannalta olennaisista suureista, joita tyypillisesti ovat esimerkiksi ilman lämpötila ja nopeus. Simulointimallin laskentatuloksia verrattiin testihuonetiloissa tehtyihin mittauksiin. Tulokset osoittautuivat riittävän tarkoiksi talotekniikan suunnitteluun. Mallilla simuloitiin kaksi huonetilaa, joissa tarvittiin tavallista tarkempaa mallinnusta. Vertailulaskelmia tehtiin eri turbulenssimalleilla, diskretointitarkkuuksilla ja hilatiheyksillä. Simulointitulosten havainnollistamiseksi suunniteltiin asiakastuloste, jossa on esitetty suunnittelun kannalta olennaiset asiat. Simulointimallilla saatiin lisätietoa varsinkin lämpötilakerrostumista, joita tyypillisesti on arvioitu kokemukseen perustuen. Simulointimallin kehityksen taustana käsiteltiin rakennusten sisäilmastoa, lämpöolosuhteita ja laskentamenetelmiä sekä mallinnukseen soveltuvia kaupallisia ohjelmia. Simulointimallilla saadaan entistä tarkempaa ja yksityiskohtaisempaa tietoa lämpöolosuhteiden hallinnan suunnitteluun. Mallin käytön ongelmia ovat vielä virtauslaskennan suuri laskenta-aika, turbulenssin mallinnus, tuloilmalaitteiden reunaehtojen tarkka määritys ja laskennan konvergointi. Kehitetty simulointimalli tarjoaa hyvän perustan virtauslaskenta- ja energia-analyysiohjelmien kehittämiseksi ja yhdistämiseksi käyttäjäystävälliseksi talotekniikan suunnittelutyökaluksi.
