The widespread implementation of GIS-based 3D topographical models has been a great aid in the development and testing of archaeological hypotheses. In this paper, a topographical reconstruction of the ancient city of Tarraco, the Roman capital of the Tarraconensis province, is presented. This model is based on topographical data obtained through archaeological excavations, old photographic documentation, georeferenced archive maps depicting the pre-modern city topography, modern detailed topographical maps and differential GPS measurements. The addition of the Roman urban architectural features to the model offers the possibility to test hypotheses concerning the ideological background manifested in the city shape. This is accomplished mainly through the use of 3D views from the main city accesses. These techniques ultimately demonstrate the ‘theatre-shaped’ layout of the city (to quote Vitrubius) as well as its southwest oriented architecture, whose monumental character was conceived to present a striking aspect to visitors, particularly those arriving from the sea.

Tämän tutkimuksen tavoitteena oli selvittää, voidaanko asiakkaan ja palveluntarjoajan odotukset yhdistää muodostettaessa palveluntarjoajan monikanavamallia. Monikanavaisuus tuo asiakkaalle mahdollisuuksia ajasta ja paikasta riippumattomaan asiointiin. Asiakkaan näkökulmasta tämä tarkoittaa usein sitä, että hänen oppimansa asiointitapa muuttuu. Asiakas kokee haittana sen, että joutuu panostamaan uuden asiointitavan opettelemiseen ja odottaa tämän muutoksen tuovan hänelle hyötyjä. Monikanavaisuuden hyödyt asiakkaalle punnitaan tässä muutostilanteessa. Palveluntarjoaja odottaa monikanavamallin tuovan kustannussäästöjä, sillä kanavavalinnat ovat keino kehittää asiakkuuksia ja vaikuttaa yrityksen kannattavuuteen pitkällä aikajänteellä. Monikanavamallin toteuttaminen vaatii palveluntarjoajalta alkuvaiheessa resursseja, investointeja ja halutun muutoksen tavoitteellista johtamista. Tutkittavat asiakkaat valittiin Suomen Posti Oyj:n Yritykset ja yritykset –asiakassegmentistä. Tutkimuksessa ei löytynyt asiakaskohtaisia eroja asiakkaiden odotuksista palveluntarjoajien monikanavamalleihin, mutta hyötyodotusten suhteen tunnistettiin kolme erilaista asiakastyyppiä: kustannussäästöjä odottavat hintaorientoituneet asiakkaat, palvelun entistä parempaa sujumista odottavat palveluorientoituneet asiakkaat ja oman valinnanvapautensa merkitystä painottavat asiakassuhdeorientoituneet asiakkaat. Palveluntarjoajan tulee pystyä viestimään ja argumentoimaan asiointitavan muutoksesta kullekin asiakkaalle merkityksellisellä tavalla. Teorian ja empirian pohjalta voidaan sanoa, että asiakkaan ja palveluntarjoajan odotukset voidaan yhdistää muodostettaessa palveluntarjoajan monikanavamallia. Tämä edellyttää, että palveluntarjoaja tuntee asiakkaansa niin hyvin, että tietää millaiset eri asiakkaiden hyötyodotukset ovat.

Tentative empirical evidence suggests that the agglomeration of talent contributes to regional development. However, given that talented people are not evenly distributed across regions, this paper seeks to determine how the concentration of talent affects patterns of regional development. Here, we empirically evaluate the effects of the distribution of talent on regional differences by means of a detailed analysis of the 17 Autonomous Communities of Spain between 1996 and 2004. We hypothesise that regions specialising in strategic sectors that are creative and which can be assumed to enjoy rapid growth in productivity will experience faster rates of development and, in turn, that this concentration of talent will have a positive impact on the region’s economic performance. Thus, we believe that this mechanism can explain the marked regional imbalances in Spain. Our findings confirm that regional differences, measured in terms of GDP per capita and by, - industrial and service- oriented production, are influenced by the Communities’ talent bases as determined by, educational attainment and employment in assumed to be strategic for regional development, inasmuch as these sectors provide economic specialization.

Verkostokeskeisessä sodankäynnissä tietojärjestelmien suurimpana haasteena on oikean tiedon hajauttaminen oikeaan paikkaan ja aikaan. Tietojärjestelmissä esitettävän ilmatilannekuvan tulee vastata reaalimaailman tilannetta parhaalla mahdollisella tavalla. Ilmatorjunnassa reaaliaikaisuus nousee erityisen suureen rooliin nopeasti liikkuvien kohteiden takia. Tämä diplomityö on tehty Insta DefSec Oy:ssä liittyen johtamisjärjestelmän uudistamishankkeeseen. Työn vaatimuksina olivat standardeihin perustuvat ratkaisut, joista keskeisimmäksi nousi Data Distribution Service -standardi (DDS) ja sen hyödyntäminen osana johtamisjärjestelmän tiedon hajautusta. Työssä esitellään johtamisjärjestelmien tiedon hajautukseen liittyviä haasteita sekä paikallisessa että maantieteellisesti hajautetussa toimintaympäristössä. Työssä toteutettiin liityntäohjelmisto nykyisen ja uuden johtamisjärjestelmän välille. Liityntäohjelmiston tehtävänä on tuottaa reaaliaikaista ilmatilannekuvaa nykyisestä johtamisjärjestelmästä uuteen johtamisjärjestelmään. DDS-standardin toteuttavana välikerrosarkkitehtuurina käytettiin OpenSplice DDS -tuotetta. Valittu teknologia tarjoaa edistykselliset julkaisija–tilaaja-mallin mukaiset menetelmät tiedon reaaliaikaiseen hajauttamiseen. DDS:n arkkitehtuuri ja palvelun laadun mekanismit mahdollistavat tiedon hajautuksen sodanajan johtamisjärjestelmille.

Tässä diplomityössä käydään läpi lähestymistapoja sovellusintegraatioon ja niiden käyttöä yritysmaailmassa. Sovellusintegraatiolla tarkoitetaan prosessia jolla yhdistetään toimintoja tai tietoa kahdesta tai useammasta sovelluksesta ja luodaan yhtenäinen kokonaisuus toiminnallisuuksia tai tietoa. Sovellusintegraation toteuttamiseksi on olemassa erilaisia lähestymistapoja ja menetelmiä. Näillä prosesseilla pyritään linkittämään kaksi tai useampia sovelluksia toisiinsa. Sovellusintegraation avulla saadaan jo olemassa olevista järjestelmistä tietoa, pystytään hyödyntämään elektronista kaupankäyntiä, saadaan integroituja toimitusketjuja, ja saadaan jaettua tarpeelliset prosessit. Sovellusintegraatio on strateginen lähestymistapa monen tietojärjestelmän yhteensitomiseksi. Tietojen vaihto ja reaaliaikainen toiminta on tärkeää. Sovellusintegraation tuloksena käytettävissä oleva informaatio ja prosessit sisäisten- ja ulkoisten systeemien välillä tuottavat selkeää strategista etua. Työssä toteutettiin kohdeyritykselle järjestelmä jonka avulla voidaan siirtää työtunnit projektinhallintajärjestelmästä taloushallinnon järjestelmään.

Työssä esitellään käytetyimpiä tuotantofilosofioita. Tuotantofilosofia on hyvin laaja käsite ja sen vuoksi myös jotkin esiteltävistä menetelmistä ovat hyvin kaukana toisistaan. Työ koostuu teoriaosiosta, jossa on esitelty kukin tuotantofilosofia ja lopuksi johtopäätöksiä-osiossa käsitellään sitä, kuinka menetelmät liittyvät toisiinsa. Työssä esitellään JIT/JOT-tuotanto, Lean-tuotanto, Monozukuri, Modulointi, Standardointi, Strategiatyö, Six Sigma, TQM, TPM, QFD, MFD, Simulointi, Digitaalinen valmistus, DFX ja ns. uudet tuotantofilosofiat. Eri menetelmistä löytyvää lähdemateriaalia on tarjolla monipuolisesti, josta johtuen menetelmistä on voitu esitellä vain pääpiirteet. Tuotantofilosofioiden avulla voidaan saavuttaa monia eri asioita. Osa menetelmistä on luotu tuotannon tehostamiseksi ja yksinkertaistamiseksi, osa puolestaan lisää tuotannon tai koko yrityksen laatutasoa ja osa puolestaan helpottaa tuotteiden suunnittelu-työtä. Moni esiteltävistä filosofioista ei istu yksinomaan yhteen edellä mainituista kategorioista vaan kattaa laajempia alueita pitäen sisällään jopa kaikkia kolmea mainittua tulosta. Näiden lisäksi työssä on esitelty lyhyesti uusia tuotantofilosofioita, jotka ovat hieman irrallisia kokonaisuuksia verrattuna muihin työssä esiteltäviin filosofioihin. Työn tarkoituksena on auttaa hahmottamaan suurta kokonaisuutta jonka tuotantofilosofiat tuottavat. On tärkeää osata hahmottaa filosofioiden riippuvuus toisistaan ja se, että otettaessa käyttöön jotain tuotantofilosofiaa, tarkoittaa se myös mahdollisesti monen muunkin asian huomioonottamista. Tätä näkökantaa selvennetään johtopäätöksissä.

Nykypäivänä energiansäästötavoitteet ovat haasteena yhä useammalle energiankuluttajalle. Tavoitteisiin päästäkseen yritykset ja kunnalliset energiankuluttajat kaipaavat usein apua kannattavien energiansäätökeinojen löytämiseksi. Erilaiset energiakatselmukset vastaavat tähän tarpeeseen ja ovat esimerkki tuloksellisesta energiansäästöstä. Lappeenrannan teknillinen yliopisto on tutkinut energiatehokkuutta pitkään erilaisissa projekteissa teollisuuden kanssa yhteistyössä. Osa LUT:n energiatehokkuustutkimusta ovat energia-auditoinnit yrityksille ja kunnille, joita LUT Energian projektin puitteissa alettiin kehittää vuoden 2008 syksyllä. Energia-auditointien fokuksena on pyritty pitämään pumppausprosessien energiatehokkuuden optimointia, sillä aihetta on tutkittu yliopistolla laajasti. Pumppausprosesseissa on todettu olevan merkittävä energiansäästöpotentiaali: pumppauksen kuluttamasta energiasta voi olla mahdollista säästää jopa 50 % erilaisilla laite- ja säästötaparatkaisuilla. Pumppausprosessien energia-auditointeja on tehty teollisuuden pumppauskohteisiin kuin myös kunnallisiin vesi-huoltolaitoksiin. Lisäksi energia-auditointien puitteissa on tutkittu energiansäästömahdollisuuksia rakennuksissa. Energiansäästökohteita etsitään sekä lämpö- että sähköenergian osalta. Energia-auditoinneissa pumppausten osalta energiansäästöpotentiaalia on todettu olevan etenkin suuren kokoluokan pumpuissa, joilla on pitkä vuosittainen käyttöaika. Myös pumppujen säätötavalla on suuri merkitys energiankulutukseen. Rakennusten osalta on pyritty selvittämään, kuinka energiankulutus jakautuu eri kulutusryhmien kesken. Säästökohteita on löydetty muun muassa rakennusten tiiviydestä, ilmanvaihdosta kuin valaistuksestakin. Monia auditointien asiakkaita on kiinnostanut etenkin led-teknologian hyödyntäminen yleisvalaistuksessa sekä muut keinot säästää valaistuksen energiankulutuksessa. Pyrkimyksenä on kehittää energia-auditointeja projektin aikana saavutettujen kokemusten avulla sekä myös liiketaloudellisessa mielessä opinnäytetutkielmien avulla. Menestyksekäs palveluliiketoiminta edellyttää määriteltyjä toimintatapoja, riittävän tarkkaa palvelujen rajausta ja koko energia-auditointiprosessin kehittämistä aina asiakassuhteen luomisesta sen jatko-hoitoon saakka.

The aim of the present dissertation is to investigate the marketing culture of research libraries in Finland and to understand the awareness of the knowledge base of library management concerning modern marketing theories and practices. The study was based onthe notion that a leader in an organisation can have large impact on its culture. Therefore, it was considered important to learn about the market orientation that initiates at the top management and flows throughout the whole organisationthus resulting in a particular kind of library culture. The study attempts to examine the marketing culture of libraries by analysing the marketing attitudes, knowledge (underlying beliefs, values and assumptions), behaviour (market orientation), operational policies and activities, and their service performance (customer satisfaction). The research was based on the assumption that if the top management of libraries has market oriented behaviour, then their marketing attitudes, knowledge, operational policies and activities and service performance should also be in accordance. The dissertation attempts to connect all these theoretical threads of marketing culture. It investigates thirty three academic and special libraries in the south of Finland. The library director and three to ten customers from each library participated as respondents in this study. An integrated methodological approach of qualitative as well as quantitative methods was used to gain knowledge on the pertinent issues lying behind the marketing culture of research libraries. The analysis of the whole dissertation reveals that the concept of marketing has very varied status in the Finnish research libraries. Based on the entire findings, three kinds of marketing cultures were emerged: the strong- the high fliers; the medium- the brisk runners; and the weak- the slow walkers. The high fliers appeared to be modern marketing believers as their marketing approach was customer oriented and found to be closer to the emerging notions of contemporary relational marketing. The brisk runners were found to be traditional marketing advocates as their marketing approach is more `library centred¿than customer defined and thus is in line of `product orientation¿ i.e. traditional marketing. `Let the interested customers come to the library¿ was appeared to be the hallmark of the slow walkers. Application of conscious market orientation is not reflected in the library activities of the slow walkers. Instead their values, ideology and approach to serving the library customers is more in tuneof `usual service oriented Finnish way¿. The implication of the research is that it pays to be market oriented which results in higher customer satisfaction oflibraries. Moreover, it is emphasised that the traditional user based service philosophy of Finnish research libraries should not be abandoned but it needs to be further developed by building a relational based marketing system which will help the libraries to become more efficient and effective from the customers¿ viewpoint. The contribution of the dissertation lies in the framework showing the linkages between the critical components of the marketing culture of a library: antecedents, market orientation, facilitators and consequences. The dissertationdelineates the significant underlying dimensions of market-oriented behaviour of libraries which are namely customer philosophy, inter-functional coordination,strategic orientation, responsiveness, pricing orientation and competition orientation. The dissertation also showed the extent to which marketing attitudes, behaviour, knowledge were related and impact of market orientation on the serviceperformance of libraries. A strong positive association was found to exist between market orientation and marketing attitudes and knowledge. Moreover, it also shows that a higher market orientation is positively connected with the service performance of libraries, the ultimate result being higher customer satisfaction. The analysis shows that a genuine marketing culture represents a synthesis of certain marketing attitudes, knowledge and of selective practices. This finding is particularly significant in the sense that it manifests that marketing culture consists of a certain sets of beliefs and knowledge (which form a specific attitude towards marketing) and implementation of a certain set of activities that actually materialize the attitude of marketing into practice (market orientation) leading to superior service performance of libraries.

Ontario Colleges of Applied Arts and Technology (CAATs) are currently in the process of restructuring to ensure quality, accountability, and accessibility of college education. References to learner involvement and self-directed learning are prevalent. "Alternative delivery" and "paradigm shift" are current buzzwords within the Ontario CAAT system as an environment is created supportive of change. Instability of funding has also dictated a need for change. Therefore, a focus has become quality of learning with less demand on public resources. This qualitative case study was conducted at an Ontario CAAT to gather descriptive, perceptual data from post-secondary community college educators who were identified as supportive of self-directed learning and from post-secondary, traditional-aged college students who were perceived by their educators to be selfdirected learners. This college was selected because of initiatives to modify its academic paradigm to encourage what was reputed in the Ontario CAAT system to be self-directed learning. The purpose of this study was to investigate how postsecondary, traditional-aged college students and their educators perceive self-directed learning as part of the teaching-learning experience within a community college setting. Educator participants of the study were selected based on the results of a teaching and learning survey intended to identify educators supportive of self-directed learning. A total of 317 surveys were distributed to every full-time educator at the sample college; 192 completed surveys were returned for a return rate of 61 %. Of these, 8% indicated instructional beliefs and values supportive of self-directed learning. A purposive sample of six educators was selected using a maximulp variation sampling strategy. A network selection sampling strategy was used to select a purposive sample of seven post-secondary students who were identified by the sample educators as selfdirected learners. The results of the study show that students and educators have similar perspectives and operating definitions of self-directed learning and all participants believe they either practice or facilitate self-directed learning. However, their perspectives and practices are not consistent with the literature which emphasizes learner autonomy or control in course structure and content. A central characteristic of the participants represented in this study is the service-oriented professions with which each is associated. Experientiallearning opportunities were highly valued for the options provided in increasing learner independence and competencies in reflective practice. Although there were discrepancies between espoused theory and theory in practice in terms of course structure, the process of self-directed learning was being practiced and supported outside the classroom structure in clinical settings, labs and related experiences.

Managers are central to any fuction in a complex and developed society. Their talents are reckoned to be cardinal in developed economies and a basic yearning of all developing economies.In order to survive and produce results in a turbulent and transient environment, the task is to understand the nature of factors contributing to managerial effectiveness. This study is an attempt towards this core issue of the present from a different perspective. This study tries to focus attention on a group of managers functioning in the field of banking, a core sector in the country's economy. The gamut of economic activities in Kerala being predominantly service-oriented, importance of commercial banking is almost indisputable. Though economists would argue that the disproportionate development of service sector is anomalous when viewed against the hazy scenarios in the primary and secondary sectors of the state’s economy, the extent and pace of growth in the banking sector has had its dole meted out by ambitious and productive managers fiinctioning in the field. Researcher’s attempt here is to thresh the grain and chaff among bank managers in terms of their effectiveness and to account for the variations in the light of their ability to affect the thoughts and actions of their subordinates. To put it succinctly, the attempt herein is to explain the effectiveness of bank managers in the light of their ‘Power Profile’ taken to be comprising Power Differentials, Power Bases, their Visibility and Credibility in the organisation and, the Power Styles typically used by them for influencing subordinates.

Since 1999, with the adoption of expansion policy in higher education by the Chinese government, enrollment and graduate numbers have been increasing at an unprecedented speed. Accustomed to a system in which university graduates were placed, many students are not trained in “selling themselves”, which exacerbates the situation leading to a skyrocketing unemployment rate among new graduates. The idea of emphasizing career services comes with increasing employment pressure among university graduates in recent years. The 1998 “Higher Education Act” made it a legislative requirement. Thereafter, the Ministry of Education issued a series of documents in order to promote the development of career services. All higher education institutions are required to set up special career service centers and to set a ratio of 1:500 between career staff and the total number of students. Related career management courses, especially career planning classes, are required to be clearly included as specific modules into the teaching plan with a requirement of no less than 38 sessions in one semester at all universities. Developing career services in higher education has thus become a hot issue. One of the more notable trends in higher education in recent years has been the transformation of university career service centers from merely being the coordinators of on-campus placement into full service centers for international career development. The traditional core of career services in higher education had been built around guidance, information and placements (Watts, 1997). This core was still in place, but the role of higher education career services has changed considerably in recent years and the nature of each part is being transformed (Watts, 1997). Most services are undertaking a range of additional activities, and the career guidance issue is emphasized much more than before. Career management courses, especially career planning classes, are given special focus in developing career services in the Chinese case. This links career services clearly and directly with the course provision function. In China, most career service centers are engaging in the transformation period from a “management-oriented” organization to a “service-oriented” organization. Besides guidance services, information services and placement activities, there is a need to blend them together with the new additional teaching function, which follows the general trend as regulated by the government. The role of career services has been expanding and this has brought more challenges to its development in Chinese higher education. Chinese universities still remain in the period of exploration and establishment in developing their own career services. In the face of the new situation, it is very important and meaningful to explore and establish a comprehensive career services system to address student needs in the universities. A key part in developing this system is the introduction of career courses and delivering related career management skills to the students. So there is the need to restructure the career service sectors within the Chinese universities in general. The career service centers will operate as a hub and function as a spoke in the wheel of this model system, providing support and information to staff located in individual teaching departments who are responsible for the delivery of career education, information, advice and guidance. The career service centers will also provide training and career planning classes. The purpose of establishing a comprehensive career services system is to provide a strong base for student career development. The students can prepare themselves well in psychology, ideology and ability before employment with the assistance of effective career services. To conclude, according to the different characteristics and needs of students, there will be appropriate services and guidance in different stages and different ways. In other words, related career services and career guidance activities would be started for newly enrolled freshmen and continue throughout their whole university process. For the operation of a comprehensive services system, there is a need for strong support by the government in the form of macro-control and policy guarantee, but support by the government in the form of macro-control and policy guarantee, but also a need for close cooperation with the academic administration and faculties to be actively involved in career planning and employment programs. As an integral function within the universities, career services must develop and maintain productive relationships with relevant campus offices and key stakeholders both within the universities and externally.

The service-oriented approach to performing distributed scientific research is potentially very powerful but is not yet widely used in many scientific fields. This is partly due to the technical difficulties involved in creating services and workflows and the inefficiency of many workflow systems with regard to handling large datasets. We present the Styx Grid Service, a simple system that wraps command-line programs and allows them to be run over the Internet exactly as if they were local programs. Styx Grid Services are very easy to create and use and can be composed into powerful workflows with simple shell scripts or more sophisticated graphical tools. An important feature of the system is that data can be streamed directly from service to service, significantly increasing the efficiency of workflows that use large data volumes. The status and progress of Styx Grid Services can be monitored asynchronously using a mechanism that places very few demands on firewalls. We show how Styx Grid Services can interoperate with with Web Services and WS-Resources using suitable adapters.
