Are Evaluation of ICTs Investment Using Decision Support Systems:Case Applications from Distributor's and End User's Perspective Group Decision

The evaluation of investments in advanced technology is one of the most important decision making tasks. The importance is even more pronounced considering the huge budget concerning the strategic, economic and analytic justification in order to shorten design and development time. Choosing the most appropriate technology requires an accurate and reliable system that can lead the decision makers to obtain such a complicated task. Currently, several Information and Communication Technologies (ICTs) manufacturers that design global products are seeking local firms to act as their sales and services representatives (called distributors) to the end user. At the same time, the end user or customer is also searching for the best possible deal for their investment in ICT's projects. Therefore, the objective of this research is to present a holistic decision support system to assist the decision maker in Small and Medium Enterprises (SMEs) - working either as individual decision makers or in a group - in the evaluation of the investment to become an ICT's distributor or an ICT's end user. The model is composed of the Delphi/MAH (Maximising Agreement Heuristic) Analysis, a well-known quantitative method in Group Support System (GSS), which is applied to gather the average ranking data from amongst Decision Makers (DMs). After that the Analytic Network Process (ANP) analysis is brought in to analyse holistically: it performs quantitative and qualitative analysis simultaneously. The illustrative data are obtained from industrial entrepreneurs by using the Group Support System (GSS) laboratory facilities at Lappeenranta University of Technology, Finland and in Thailand. The result of the research, which is currently implemented in Thailand, can provide benefits to the industry in the evaluation of becoming an ICT's distributor or an ICT's end user, particularly in the assessment of the Enterprise Resource Planning (ERP) programme. After the model is put to test with an in-depth collaboration with industrial entrepreneurs in Finland and Thailand, the sensitivity analysis is also performed to validate the robustness of the model. The contribution of this research is in developing a new approach and the Delphi/MAH software to obtain an analysis of the value of becoming an ERP distributor or end user that is flexible and applicable to entrepreneurs, who are looking for the most appropriate investment to become an ERP distributor or end user. The main advantage of this research over others is that the model can deliver the value of becoming an ERP distributor or end user in a single number which makes it easier for DMs to choose the most appropriate ERP vendor. The associated advantage is that the model can include qualitative data as well as quantitative data, as the results from using quantitative data alone can be misleading and inadequate. There is a need to utilise quantitative and qualitative analysis together, as can be seen from the case studies.

¿Innovar o 'maquillar'? La incorporación de las TICs a los procesos político-administrativos

What criteria should guide the process of incorporating ICTs into political realm? Are ICTs, per definitionem, an instrument that always generates positive effects for political activity? Our reflection aims to influence the necessary and essential process of analysis prior to the introduction of ICT in the field of political processes, focusing primarily on the delimitation of its effects. In this sense it highlights the need to assess the added value of introducing a technological solution in the political process prior to do it, what will validate or not its desirability. There is, in this sense, the excessive use of 'make-up' technology of political processes, that is, the absence of real & practical innovation.

Modelling of the PWR PACTEL vertical steam generator with the TRACE code

The behavior of the nuclear power plants must be known in all operational situations. Thermal hydraulics computer applications are used to simulate the behavior of the plants. The computer applications must be validated before they can be used reliably. The simulation results are compared against the experimental results. In this thesis a model of the PWR PACTEL steam generator was prepared with the TRAC/RELAP Advanced Computational Engine computer application. The simulation results can be compared against the results of the Advanced Process Simulator analysis software in future. Development of the model of the PWR PACTEL vertical steam generator is introduced in this thesis. Loss of feedwater transient simulation examples were carried out with the model.

Surface Modification of Ceramics

Ceramics are widely used in industrial applications due to their advantageous thermal and mechanical stability. Corrosion of ceramics is a great problem resulting in significant costs. Coating is one method of reducing adversities of corrosion. There are several different thin film deposition processes available such as sol-gel, Physical and Chemical Vapour Deposition (PVD and CVD). One of the CVD processes, called Atomic Layer Deposition (ALD) stands out for its excellent controllability, accuracy and wide process capability. The most commonly mentioned disadvantage of this method is its slowness which is partly compensated by its capability of processing large areas at once. Several factors affect the ALD process. Such factors include temperature, the grade of precursors, pulse-purge times and flux of precursors as well as the substrate used. Wrongly chosen process factors may cause loss of self-limiting growth and thus, non-uniformities in the deposited film. Porous substrates require longer pulse times than flat surfaces. The goal of this thesis was to examine the effects of ALD films on surface properties of a porous ceramic material. The analyses applied were for permeability, bubble point pressure and isoelectric point. In addition, effects of the films on corrosion resistance of the substrate in aqueous environment were investigated. After being exposured to different corrosive media the ceramics and liquid samples collected were analysed both mechanically and chemically. Visual and contentual differences between the exposed and coated ceramics versus the untreated and uncoated ones were analysed by scanning electron microscope. Two ALD film materials, dialuminium trioxide and titanium dioxide were deposited on the ceramic substrate using different pulse times. The results of both film materials indicated that surface properties of the ceramic material can be modified to some extent by the ALD method. The effect of the titanium oxide film on the corrosion resistance of the ceramic samples was observed to be fairly small regardless of the pulse time.

Role of Capabilities in Purchasing and Supply Management Performance

The objective of this thesis was to study the role of capabilities in purchasing and supply management. For the pre-understanding of the research topic, purchasing and supply management development and the multidimensional, unstructured and complex nature of purchasing and supply management performance was studied in literature review. In addition, a capability-based purchasing and supply management performance framework were researched and structured for the empirical research. Due to the unstructured nature of the research topic, the empirical research is three-pronged in this study including three different research methods: the Delphi method, semi-structured interview, and case research. As a result, the purchasing and supply management capability assessment tool was structured to measure current level of capabilities and impact of capabilities on purchasing and supply management performance. The final results indicate that capabilities are enablers of purchasing and supply management performance, and therefore critical to purchasing and supply performance.

The role of chemokines and chemokine receptors in eosinophil activation during inflammatory allergic reactions

Chemokines are important chemotactic cytokines that play a fundamental role in the trafficking of leukocytes to sites of inflammation. They are also potent cell-activating factors, inducing cytokine and histamine release and free radical production, a fact that makes them particularly important in the pathogenesis of allergic inflammation. The action of chemokines is regulated at the level of agonist production and processing as well as at the level of receptor expression and coupling. Therefore, an analysis of the ligands must necessarily consider receptors. Eosinophils are target cells involved in the allergic inflammatory response since they are able to release a wide variety of mediators including CC and CXC chemokines and express their receptors. These mediators could damage the airway epithelial cells and might be important to stimulate other cells inducing an amplification of the allergic response. This review focuses on recently emerging data pertaining to the importance of chemokines and chemokine receptors in promoting eosinophil activation and migration during the allergic inflammatory process. The analysis of the function of eosinophils and their chemokine receptors during allergic inflammation might be a good approach to understanding the determinants of asthma severity and to developing novel therapies.

The effects of congestion in the daily management of a trauma hospital

Today’s healthcare organizations are under constant pressure for change, as hospitals should be able to offer their patients the best possible medical care with limited resources and, at the same time, to retain steady efficiency level in their operation. This is challenging, especially in trauma hospitals, in which the variation in the patient cases and volumes is relatively high. Furthermore, the trauma patient's care requires plenty of resources as most the patients have to be treated as single cases. Occasionally, the sudden increases in demand causes congestion in the operations of the hospital, which in Töölö hospital appears as an increase in the surgery waiting times within the yellow urgency class patients. An increase in the surgery waiting times may cause the diminution of the patient's condition, which also raises the surgery risks. The congestion itself causes overloading of the hospital capacity and staff. The aim of this master’s thesis is to introduce the factors contributing to the trauma process, and to examine the correlation between the different variables and the lengthened surgery waiting times. The results of this study are based on a three-year patient data and different quantitative analysis. Based on the analysis, a daily usable indicator was created in order to support the decision making in the operations management. By using the selected indicator, the effects of congestion can be acknowledged and the corrective action can also be taken more proactively.

Sponsor Satisfaction in a Regional Charity Sport Event

The purpose of this Master’s thesis is to study sponsor satisfaction in charity sport events. Lack of research in regional charity sport events, emergence of corporate social responsibility and increasing popularity of charity sport events have created a research gap to be further explored. Theoretical part of the thesis focuses in development of sponsorships, charity sport event sponsorships and sponsorship as a marketing tool. Concept of satisfaction is discussed by implementing marketing theories to weight options on measuring sponsor satisfaction as a part of sponsorship evaluation process. Empirical analysis of the thesis was conducted in a regional charity sport event – Maailman Pisin Salibandyottelu. Evidences were collected in qualitative research method through semi-structured theme interviews. Altogether 12 major and minor sponsors were selected for the primary source of data. The data was analyzed by comparing sponsors’ expectations and experiences, and by displaying sponsors’ perceived satisfaction. The results indicated that sponsors were involved by partly altruistic and partly selfish motives as suggested by previous research. Respondents expressed very few, mainly non-financial expectations, yet were hoping to gain positive image association via event exposure. Negative experiences appear to have relatively small impact in overall satisfaction. Exceeding or fulfilling expectations appears to increase perceived satisfaction which was mainly driven by contribution towards the goodwill, perceived success of the event (successful record attempt, visibility (on- and off-line) and event execution.

Teleskooppipuomin valmistuksen kehittäminen

KESLA 2110T -autonosturin siirtopuomin teleskooppimainen rakenne koostuu kolmesta sisäkkäin menevästä puomista. Näiden puomien muodonmuutokset ja mittavaihtelut ovat kriittisiä seikkoja siirtopuomin kokoonpantavuuden kannalta. Liian suuret muodonmuutokset ja mittavaihtelut aiheuttavat ylimääräistä työtä siirtopuomien kokoonpanossa, mikä lisää tuotteen läpimenoaikaa ja valmistuskustannuksia. Työssä pyrittiin selvittämään valmistusprosessin kriittisimmät osat kokoonpantavuuden kannalta sekä varmistamaan niiden vaikutus mittauksin. Valmistusprosessin ongelmakohtia selvitettiin ensin haastattelemalla tuotannon työntekijöitä ja toimihenkilöitä. Saatujen tuloksien perusteella suunniteltiin tarkoituksenmukaiset mittausjärjestelyt, joilla valmistusprosessin ongelmakohdat voidaan todeta. Mittaukset suoritettiin kahdelle viiden siirtopuomin koesarjalle ja samalla kehitettiin valmistusprosessia. Puomien mittauksissa keskityttiin kokoonpanon kannalta kriittisiin mittoihin. Mittatuloksia arvioidaan toleranssien, standardien ja prosessien suorituskyvyn parametrien avulla. Työssä selvitettiin myös rullamuovauksen soveltuvuutta puomien valmistusmenetelmäksi sekä välyksen vaikutusta kokoonpantavuuden kehittämiseksi. Mittauksissa havaittiin mittavirheiden kertautuvan valmistusprosessin varrella. Kokoonpantavuuden kannalta kriittisimmät virheet ovat puomien alakotelon V-pohjan toislaitaisuus sekä puomien kieroutuminen hitsausvaiheessa. Puomien korkeus- tai leveysvaihteluilla ei ole suurta merkitystä, sillä niitä voidaan kompensoida liukupaloja säätämällä.

Sobre a economia política do desenvolvimento e a contribuição dos serviços

On the political economy of development and the contribution of services. This paper aims to ponder on recent approaches to Political Economy of Development, that bring about new concepts about the role of services activities in the economic development process. The analysis begins by checking the new attributions of services entailed by the productive paradigm changes that have occurred since the 1970's. Then, it examines the debate about the new kind of society, called "post-industrial", which is centered in the services dynamics. Finally, it discusses the relevance of social capital disponibility, as a prime factor to attain economic development

Valukappaleiden valmistusprosessin kapeikot teräsvalimossa

Teräsvalimon toimitusprosessissa toimitusvarmuus on tärkeä tuotannon tunnusluku. Valimotuotannossa olevien lukuisten muuttujien vuoksi tuotannonsuunnittelu ja läpivirtauksen hallinta on haasteellista. Tuotteiden, valumateriaalien ja näiden yhdistelmien suuri yhtäaikainen määrä tuotannossa vaikeuttaa tuotannon ennustettavuutta sekä vaikuttaa läpivirtaukseen ja toimitusvarmuuteen. Lisäksi tuotannon eri työvaiheissa ilmenevät kapeikot rajoittavat läpivirtausta ja kasvattavat läpimenoaikoja. Kapeikkoja voidaan hyödyntää tuotannonohjauksessa jos kapeikot ovat selkeästi havaittavissa. Kapasiteetin siirtäminen ei-kapeikosta kapeikkoon lisää tuotannon läpivirtausta. Pelkkä kapeikkojen hallinta ei paranna toimitusvarmuutta jos keskeneräisen tuotannon määrä on suuri ja järjestys väärä. Tuotannon työkuormien visuaalisuuden parantaminen kaikilla työvaiheilla antaa mahdollisuuksia ohjata tuotantoa tehokkaammin. Kandidaatintyössä on tarkasteltu teräsvalimon valmistusprosessia ja selvitetty tuotannon eri vaiheissa ilmeneviä kapeikkoja. Selvitystyössä hyödynnettiin TOC-analyysiä. Keskeneräisen tuotannon määrää mitattiin useilla otannoilla eri työvaiheiden kohdalla. Tuloksia analysoimalla löydettiin tuotannon ongelmakohdat ja niihin tarvittavat kehitystoimenpiteet.

Private versus public : how one gay professor negotiates the boundaries between his personal and professional lives /

This study examined how one university professor negotiated the boundaries between his personal life as a gay man and his professional life as a teacher. Using his sexual orientation as a focal point, the study explored the circumstances and underlying assumptions that influenced this professor's decisions to disclose information of a personal nature. Data collection was solicited from a number of sources: (a) In-depth interviews with the participant, his colleagues, students, and friends; (b) Field observation of the participant teaching over a 3 -day period; and (c) A document review of lesson plans, course outlines, student feedback forms, and the participant's teaching portfolio. The researcher maintained both observation journals and reflective journals during this process. Data analysis using the constant comparative method elicited several themes. The participant engaged in a variety of strategies in disclosing his sexual orientation that included: (a) no disclosure at all, (b) assuming people knew, (c) casually mentioning it in conversation, and (d) deliberately planning to tell someone. The participant also engaged in an ongoing assessment of his environment that included evaluating the level of risk in disclosing his sexual orientation and assessing the listener's ability to receive the information. The participant cited numerous reasons for disclosing his sexual orientation. Further inquiry revealed a number of belief systems that underlined these reasons. These belief systems included beliefs around privacy, authenticity, teaching, manners, professionalism, and homosexuality. The conclusions suggested that the participant utilized a consistent process in both his personal and professional lives to determine what information was kept private and what information was made public. While the process used to determine the degree of disclosure was consistent, the actual disclosures themselves varied widely in nature.

The elderly : reminiscing, coping with loss, accepting death

This study investigated loss, death and dying, reminiscing, coping and the process of adaptation from the sUbjective perspective. A number of theories and models of death and dying were reviewed in the background literature search with the focus on reminiscing as a coping phenomenon. The format of the study was audio-taped interviews with ten sUbjects and the recording of their memories and reminiscing of life stories. The sUbjects were required to complete an initial questionnaire in a demographic data collection process. Two separate interviews consisted of a primary data collecting interview and a verification interview four to eight weeks later. An independent chart review completed the data collecting process. Data analysis was by the examination of the emerging themes in the subjects' personal narratives which revealed the sUb-categories of reminiscing, loss (including death and dying), acceptance, hope, love, despair and belief. Belief was shown to be the foundation and the base for living and reminiscing. Reminiscing was found to be a coping phenomenon, within the foundation of a belief system. Both living and reminiscing revealed the existence of a central belief or value with a great deal of importance attached to it. Whether the belief was of a spiritual nature, a value of marriage, tradition, a work ethic or belief in an abstract value such as fate,it gave support and control to the individuals' living and reminiscing process. That which caused despair or allowed acceptance indicated the sUbjects' basic belief and was identified in the story narrations. The findings were significant to health care in terms of education, increased dignity for the elderly and better understanding by society. The profiles represented an average age of 86.3 years with age showing no bearing on the life experiences associated with the emerging themes. Overwhelmingly, belief was shown to be the foundation in reminiscing. A Judeo-Christian cultural value base supported the belief in 90% of the sUbjects; however, different beliefs were clearly shown indicating that belief is central to all thinking beings, in everyday life and in reminiscing. Belief was not necessarily spiritual or a practised or verbalized religion. It was shown to be a way of understanding, a fundamental and single thread tying the individual's life and stories together. The benefits were the outcomes, in that knowledge of an individual's belief can optimize care planning for any age group, and/or setting. The strength of the study was the open question format and the feedback process of data verification. The unrestricted outcomes and non-specificity were significant in a world where dying is everybody's business.

La signification de la qualité de vie au travail pour des infirmiers œuvrant en CSSS, mission CLSC et déclarant avoir une qualité de vie positive au travail

Depuis le début des années 90, le réseau de la santé au Québec est soumis à une vaste restructuration qui a eu des conséquences négatives sur la qualité de vie au travail (QVT) des infirmières et infirmiers. Les hommes se retrouvent en nombre croissant dans toutes les sphères de la pratique infirmière, mais les études existantes ne font malheureusement pas mention de la qualité de vie au travail de ceux-ci. Alors, il apparaît pertinent de s’attarder au phénomène de la qualité de vie au travail des hommes infirmiers dans la profession infirmière, et ce, plus précisément en CSSS mission CLSC. Le but de cette étude phénoménologique consiste à décrire et à comprendre la signification de la qualité de vie au travail pour des infirmiers œuvrant en CSSS mission CLSC. L’essence du phénomène, les huit thèmes et les 35 sous-thèmes qui se dégagent directement des entrevues énoncent que la signification de la qualité de vie au travail pour des infirmiers œuvrant en centre de santé et des services sociaux (CSSS), mission CLSC et déclarant avoir une qualité de vie positive au travail, signifie « un climat empreint de caring qui favorise l'épanouissement de l'infirmier en CLSC en œuvrant pour le maintien de l'harmonie entre les sphères professionnelle et familiale ». Si certains résultats corroborent ceux d’études antérieures, d’autres apportent des éléments nouveaux favorisant la santé des infirmiers par le biais de la qualité de vie au travail. Enfin, des avenues concrètes visant la mise en place de programmes d’optimisation de la qualité de vie au travail, sont proposées.
