This report describes the continuation of the development of performance measures for the Iowa Department of Transportation (DOT) Offices of Construction. Those offices are responsible for administering transportation construction projects for the Iowa DOT. Researchers worked closely with the Benchmark Steering Team which was formed during Phase I of this project and is composed of representatives of the Offices of Construction. The research team conducted a second survey of Offices of Construction personnel, interviewed numerous members of the Offices and continued to work to improve the eight key processes identified during Phase I of this research. The eight key processes include Inspection of Work, Resolution of Technical Issues, Documentation of Work Progress and Pay Quantities, Employee Training and Development, Continuous Feedback for Improved Contract Documents, Provide Safe Traffic Control, External/Public Communication, and Providing Pre-Letting Information. Three to four measurements were specified for each key process. Many of these measurements required opinion surveys of employees, contractors, and others. During Phase II, researchers concentrated on conducting surveys, interviewing respondents to improve future surveys, and facilitating Benchmark Steering Team monthly meetings. Much effort was placed on using the information collected during the first year's research to improve the effectiveness and efficiency of the Offices of Construction. The results from Process Improvement Teams that studied Traffic Control and Resolution of Technical Issues were used to improve operations.

Granular shoulders need to be maintained on a regular basis because edge ruts and potholes develop, posing a safety hazard to motorists. The successful mitigation of edge-rut issues for granular shoulders would increase safety and reduce the number of procedures currently required to maintain granular shoulders in Iowa. In addition, better performance of granular shoulders reduces the urgency to pave granular shoulders. Delaying or permanently avoiding paving shoulders where possible allows more flexibility in making investments in the road network. To stabilize shoulders and reduce the number of maintenance cycles necessary per season, one possible stabilizing agent—acidulated soybean oil soapstock—was investigated in this research. A pilot testing project was conducted for selected problematic shoulders in northern and northeastern Iowa. Soapstock was applied on granular shoulders and monitored during application and pre- and post-application. Application techniques were documented and the percentage of application success was calculated for each treated shoulder section. As a result of this research, it was concluded that soybean oil soapstock can be an effective stabilizer for granular shoulders under certain conditions. The researchers also developed draft specifications that could possibly be used to engage a contractor to perform the work using a maintenance-type construction contract. The documented application techniques from this project could be used as guidance for those who want to apply soapstock for stabilizing granular shoulders but might not be familiar with this technique.

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.

Reconstruction of bridge approach slabs which have failed due to a loss of support from embankment fill consolidation or erosion can be particularly challenging in urban areas where lane closures must be minimized. Precast prestressed concrete pavement is a potential solution for rapid bridge approach slab reconstruction which uses prefabricated pavement panels that can be installed and opened to traffic quickly. To evaluate this solution, the Iowa Department of Transportation constructed a precast prestressed approach slab demonstration project on Highway 60 near Sheldon, Iowa in August/September 2006. Two approach slabs at either end of a new bridge were constructed using precast prestressed concrete panels. This report documents the successful development, design, and construction of the precast prestressed concrete bridge approach slabs on Highway 60. The report discusses the challenges and issues that were faced during the project and presents recommendations for future implementation of this innovative construction technique.

The Iowa Department of Transportation (Iowa DOT) UTW Project (HR-559) initiated Ultra-Thin Whitetopping in Iowa. The project is located on Iowa Highway 21 between Iowa Highway 212 and U.S. Highway 6 in Iowa County, near Belle Plaine, Iowa. The above listed research project lasted for five years, and then was extended for another five year period. The new phase of the project (TR 432) was initiated by removing cracked panels existing in the 2-inch thick PCC sections and replacing them with three inches of PCC. The project extension provides an increased understanding of slab bonding conditions over a longer period, as well as knowledge regarding the behavior of the newly rehabilitated areas. This report documents the rehabilitation of the PCC patching of all fractured panels and several cracked panels, taking place in September of 2001.

This report describes test results from a full-scale embankment pilot study conducted in Iowa. The intent of the pilot project was to field test and refine the proposed soil classification system and construction specifications developed in Phase II of this research and to evaluate the feasibility of implementing a contractor quality control (QC) and Iowa DOT quality assurance (QA) program for earthwork grading in the future. One of the primary questions for Phase III is “Was embankment quality improved?” The project involved a “quality conscious” contractor, well-qualified and experienced Iowa Department of Transportation field personnel, a good QC consultant technician, and some of our best soils in the state. If the answer to the above question is “yes” for this project, it would unquestionably be “yes” for other projects as well. The answer is yes, the quality was improved, even for this project, as evidenced by dynamic cone penetrometer test data and the amount of disking required to reduce the moisture content to within acceptable control limits (approximately 29% of soils by volume required disking). Perhaps as important is that we know what quality we have. Increased QC/QA field testing, however, increases construction costs, as expected. The quality management-earthwork program resulted in an additional $0.03 per cubic meter, or 1.6%, of the total construction costs. Disking added about $0.04 per cubic meter, or 1.7%, to the total project costs. In our opinion this is a nominal cost increase to improve quality. It is envisioned that future contractor innovations have the potential for negating this increase. The Phase III results show that the new soil classification system and the proposed field test methods worked well during the Iowa Department of Transportation soils design phase and during the construction phase. Recommendations are provided for future implementation of the results of this study by city, county, and state agencies.

Tutkimus keskittyy hankintatoimen kehittämiseen osana laitosprojektien toteutusta. Työ pohjautuu empiiriseltä taustaltaan Pöyry Oyj:n projektiliiketoimintaan ja työn tarkastelunäkökulmaksi onvalittu projektihallinnosta vastaavan yrityksen näkökulma. Tutkimus on hyvin käytännönläheinen ¿ se lähtee hankinnan ja sen seurannan ongelmista ja pyrkii tarjoamaan niihin uudenlaisia ratkaisuja. Pohjimmiltaan tutkimus kuuluu teollisuustalouden piiriin, vaikka tietojärjestelmätieteellä on vahva tukirooli. Työn tavoitteet ja tulokset liittyvät teollisuustaloudelle ominaisesti yrityksen toiminnan kehittämiseen, käytetyt välineet ja ratkaisut puolestaan hyödyntävät tietojärjestelmätieteen antamia mahdollisuuksia. Tutkimuksessa on käytetty konstruktiivista tutkimusotetta, jonka mukaisesti on luotu innovatiivisia konstruktioita ratkaisemaan aitoja reaalimaailman ongelmia ja tätä kautta tuotettu kontribuutioita teollisuustaloudelle. Tavoitteena oli järjestää hankintatoimi ja sen seuranta suurissa laitosprojekteissa tehokkaammin. Tätä varten uudistettiin ensin projektihallinnon ja hankintatoimen toimintaohjeet vastaamaan paremmin nykyajan vaatimuksia. Toimintaohjeiden perusteella ryhdyttiin toteuttamaan hankintaohjelmistoa, joka pystyisi kattamaan kaikki toimintaohjeissa kuvatut piirteet. Lopulta hankintaohjelmisto toi mukanaan uusia piirteitä projektihallintoon ja hankintatoimeen ja nämä sisällytettiin toimintaohjeisiin. Tähän kehitystyöhön ryhdyttiin, jotta laitosprojektien projektihallinto ja hankintatoimi toimisivat paremmin, eli pienemmin kustannuksin tuottaen projekteissa tarvittavat tulokset nopeammin, tarkemmin ja laadukkaammin. Tutkimuksella on kolmenlaisia tuloksia: hankintatoimen parannetut metodit, hankintaohjelmiston pohjana olevat toiminta- ja laskentamallit sekä implementaationa hankintasovellus. Uudistetut projekti- ja hankintaohjeet kuvaavat hankintatoiminnan parannettuja metodeja. Hankintaohjelmistoasuunnitellessa ja kehitettäessä tehdyt kuvaukset sisältävät uusia malleja niin hankintaprosessille kuin hankinnan seuraamiseksi suurissa laitosprojekteissa. Itse ohjelmisto on tuloksena implementaatio, joka perustuu parannettuihin hankintametodeihin ja uusiin toiminta- ja laskentamalleihin. Uudistetut projekti- ja hankintaohjeet ovat olleet käytössä Pöyry Oyj:ssä vuodesta 1991. Vuosien varrella nämä toimintaohjeet ovat auttaneet ja tukeneet satojen laitosprojektientoteutusta ja ylläpitäneet Pöyry Oyj:n kilpailukykyä kansainvälisenä projektitalona. Hankintasovellus puolestaan on ollut käytössä useissa projekteissa ja sen on havaittu pienentävän hankintatoimen suoria työkustannuksia laitosprojekteissa. Sovelluksen katsotaan myös tuovan epäsuoria kustannussäästöjä parempien hankintapäätösten muodossa, mutta näiden säästöjen suuruutta ei pystytä luotettavasti arvioimaan.

Tämän diplomityön tavoitteena oli tutkia erään projektiliiketoimintaa harjoittavan yrityksen toimintajärjestelmää. Työn lähtökohtana oli yrityksen toimittamien projektien laajuuden nopea kasvu lähivuosien aikana. Työssä tutkittiin yrityksen nykyistä toimintajärjestelmää ja sen ohjeistusta nimen omaan EPC (engineering procurement construction) projekteissa. Toimintajärjestelmän ohjeistusta tutkittiin yrityksessä tehdyillä henkilöhaastatteluilla sekä vertaamalla olemassa olevia ohjeita ja kuvauksia projektin hallinnan ja johtamisen teorioihin. Teoriat, joihin yrityksen toimintajärjestelmää työssä verrattiin olivat Project Management Institute:n, Project Management Body of Knowledge ja International standard ISO 10006, Quality Management guidelines to quality in project management. Työn teoriaosassa käsiteltiin projektin hallintaa ja johtamista, projektin eri vaiheita, projektin organisointia ja ositusta sekä projektikulttuuria. Työn tuloksena luotiin käsitys siitä, mitä osaprosesseja EPC-projektin hallintaan ja johtamiseen kohdeyrityksessä liittyy. Prosesseja tutkimalla muodostettiin käsitys yrityksen toimintajärjestelmän ohjeistuksen tasosta ja esitettiin tältä pohjalta mahdollisuuksia toimintajärjestelmän kehittämiseksi. Yhtenä työn keskeisimmistä tuloksista esitettiin EPC-projektin projektikuvaus.

The European Cancer Registry-based project on hematologic malignancies (HAEMACARE), setup to improve the availability and standardization of data on hematologic malignancies in Europe, used the European Cancer Registry-based project on survival and care of cancer patients (EUROCARE-4) database to produce a new grouping of hematologic neoplasma(defined by the International Classification of Diseases for Oncology, Third Edition and the 2001/2008 World Health Organization classifications) for epidemiological and public healthpurposes. We analyzed survival for lymphoid neoplasms in Europe by disease group, comparing survival between different European regions by age and sex. Design and Methods Incident neoplasms recorded between 1995 to 2002 in 48 population-based cancer registries in 20 countries participating in EUROCARE-4 were analyzed. The period approach was used to estimate 5-year relative survival rates for patients diagnosed in 2000-2002, who did not have 5years of follow up. Results: The 5-year relative survival rate was 57% overall but varied markedly between the definedgroups. Variation in survival within the groups was relatively limited across European regions and less than in previous years. Survival differences between men and women were small. The relative survival for patients with all lymphoid neoplasms decreased substantially after the age of 50. The proportion of ‘not otherwise specified’ diagnoses increased with advancing age.Conclusions: This is the first study to analyze survival of patients with lymphoid neoplasms, divided into groups characterized by similar epidemiological and clinical characteristics, providing a benchmarkfor more detailed analyses. This Europe-wide study suggests that previously noted differences in survival between regions have tended to decrease. The survival of patients with all neoplasms decreased markedly with age, while the proportion of ‘not otherwise specified’ diagnoses increased with advancing age. Thus the quality of diagnostic work-up and care decreased with age, suggesting that older patients may not be receiving optimal treatment

The aim of this study is to develop a suitable project control procedure for a target company that can be used in engineering, procurement, and construction or con-struction management contracts. This procedure contains suitable project control software and a model for the use of the software in practice. This study is divided into two main sections. Theoretical part deals with project management, focusing on cost and time dimensions in projects. Empirical part deals with the development of the project control procedure for the target compa-ny. This development takes place in two parts. In the first part, semi-structured interviews are used to find out the company’s employees’ demands and desires for the project control software which will then be used in the developed procedure. These demands and desires are compared to available software in the market and the most suitable one will be chosen. Interview results show that important factors are cost tracking, integration with other software, English language availability, references, helpdesk, and no need for regular updates. The most suitable one is CMPro5 cost control software. The chosen software is used in a pilot project, where its functions and use are analyzed. Project control procedure which will be used in the future is developed based on these procedures. The five steps in developed procedure include employment of a cost engineer, whose task is to maintain the procedure in the target company.

This thesis was carried out as a case study of a company YIT in order to clarify the sev-erest risks for the company and to build a method for project portfolio evaluation. The target organization creates new living environment by constructing residential buildings, business premises, infrastructure and entire areas worth for EUR 1.9 billion in the year 2013. Company has noted project portfolio management needs more information about the structure of project portfolio and possible influences of market shock situation. With interviews have been evaluated risks with biggest influence and most appropriate metrics to examine. The major risks for the company were evaluated by interviewing the executive staff. At the same time, the most appropriate risk metrics were considered. At the moment sales risk was estimated to have biggest impact on company‟s business. Therefore project port-folio evaluation model was created and three different scenarios for company‟s future were created in order to identify the scale of possible market shock situation. The created model is tested with public and descriptive figures of YIT in a one-year-long market shock and the impact on different metrics was evaluated. Study was conducted using con-structive research methodology. Results indicate that company has notable sales risk in certain sections of business portfolio.

Cette thèse part du constat que le cadre théorique dont les sciences sociales disposent pour décrire l’expérience de mixité conjugale n’est pas adapté à la mouvance de la situation contemporaine. La plupart des théories qui ont été élaborées pour parler de cette expérience de rencontre se conjuguent sous l’emprise de notions vieillies. En s’intéressant aux trajectoires de mixité conjugale dans le contexte du Maroc, cette thèse contribuera à développer un cadre conceptuel qui reflète la mouvance de la réalité contemporaine et ce, en posant les bases d’un habitus discursif valorisant, ce qui constitue l’originalité principale de ce projet de recherche. À partir d’un terrain ethnographique qui a placé l’anthropologie de l’expérience partagée et les récits d’expérience au cœur de la méthodologie de recherche, cette thèse dresse également un portrait ethnographique de la mixité conjugale au Maroc, ce qui a permis de documenter un sujet encore très peu exploré par les sciences sociales. Dans le cadre de cette thèse, la mixité conjugale a été appréhendée sous l’angle de la métaphore du voyage prolongé de Fernandez (2002), ce qui a contribué à dynamiser le cadre théorique entourant la mixité conjugale. En arrière-fond de cette thèse, une réflexion autour du concept de « home » (le chez-soi) suggère que le projet de construction de soi des individus contemporains qui négocient leur quotidien au croisement de références culturelles différentes (dont font partie les participants de cette recherche) n’est pas nécessairement synonyme de déracinement et de fragmentation, mais qu’il porte l’idée d’attachement et de cohérence.

El objetivo de este trabajo de grado es describir una disputa política por el significado del concepto de explotación en el marco de la redacción del “Protocolo para prevenir, reprimir y sancionar la trata de personas, especialmente mujeres y niños”, en el cual se define aquello que se entiende por trata de personas. La construcción de este concepto excluye e invisibiliza otros tipos de explotación comunes en el sistema de producción capitalista contemporánea que pertenecen al universo de violencia objetiva sistémica a través del énfasis en la explotación sexual que hace parte de la violencia subjetiva.

Actualmente se considera que las organizaciones con resultados positivos y rendimientos crecientes tienen aspectos y características particulares que las diferencian de aquellas organizaciones que no obtienen los mejores resultados en el mercado. Para que las organizaciones sean saludables deben garantizar el bienestar del empleado y comprometerse con el mejoramiento continuo del mismo. Es así como surgen las escalas de medidas de bienestar, las cuales contribuyen directamente al bienestar del empleado y sus resultados positivos dentro de la organización. Este estudio hace referencia a las medidas de bienestar más utilizadas en un periodo de diez años (2002-2012), con el propósito de establecer la relación entre las medidas de bienestar, el bienestar de los empleados y las organizaciones saludables. Para determinar dicha relación, se llevó a cabo un análisis detallado de los estudios realizados sobre las escalas de medidas de bienestar utilizadas durante el periodo de tiempo 2002 y 2012. Los resultados arrojados señalan que las medidas de bienestar más utilizadas durante este periodo son: Satisfacción laboral, Clima organizacional, Engagement y Calidad de vida laboral, mientras que las cuatro medidas de bienestar menos utilizadas son: Remuneración y Bienestar subjetivo.
