Service processes such as financial advice, booking a business trip or conducting a consulting project have emerged as units of analysis of high interest for the business process and service management communities in practice and academia. While the transactional nature of production processes is relatively well understood and deployed, the less predictable and highly interactive nature of service processes still lacks in many areas appropriate methodological grounding. This paper proposes a framework of a process laboratory as a new IT artefact in order to facilitate the holistic analysis and simulation of such service processes. Using financial services as an example, it will be shown how such a process laboratory can be used to reduce the complexity of service process analysis and facilitate operational service process control.

INTRODUCTION Managing spinal deformities in young children is challenging, particularly early onset scoliosis (EOS). Surgical intervention is often required if EOS has been unresponsive to conservative treatment particularly with rapidly progressive curves. An emerging treatment option for EOS is fusionless scoliosis surgery. Similar to bracing, this surgical option potentially harnesses growth, motion and function of the spine along with correcting spinal deformity. Dual growing rods are one such fusionless treatment, which aims to modulate growth of the vertebrae. The aim of this study was to ascertain the extent to which semiconstrained growing rods (Medtronic, Sofamor, Danek, Memphis, TN) with a telescopic sleeve component, reduce rotational constraint on the spine compared with standard "constrained / rigid" rods and hence potentially provide a more physiological mechanical environment for the growing spine. METHODS Six 40-60kg English Large White porcine spines served as a model for the paediatric human spine. Each spine was dissected into a 7 level thoracolumbar multi-segment unit (MSU), removing all non-ligamentous soft tissues and leaving 3cm of ribs either side. Pure nondestructive axial rotation moments of ±4Nm at a constant rotation rate of 8deg.s-1 were applied to the mounted MSU spines using a biaxial Instron testing machine. Displacement of each vertebral level was captured using a 3D motion tracking system (Optotrak 3020, Northern Digital Inc, Waterloo, ON). Each spine was tested in an un-instrumented state first and then with appropriately sized semi-constrained growing rods and rigid rods in alternating sequence. The rods were secured by multi-axial pedicle screws (Medtronic CD Horizon) at levels 2 and 6 of the construct. The range of motion (ROM), neutral zone (NZ) size and stiffness (Nm.deg-1) were calculated from the Instron load-displacement data and intervertebral ROM was calculated through a MATLAB algorithm from Optotrak data. RESULTS Irrespective of the order of testing, rigid rods significantly reduced the total ROM compared with semi-constrained rods (p<0.05) with in a significantly stiffer spine for both left and right axial rotation (p<0.05). Analysing the intervertebral motion within the instrumented levels 2-6, rigid rods showed reduced ROM compared with semi-constrained growing rods and compared with un-instrumented motion segments. CONCLUSION Semi-constrained growing rods maintain similar stiffness in axial rotation to un-instrumented spines, while dual rigid rods significantly reduce axial rotation. Clinically the effect of semi-constrained growing rods as observed in this study is that they would be expected to allow growth via the telescopic rod components while maintaining the axial flexibility of the spine, which may reduce occurrence of the crankshaft phenomenon.

INTRODUCTION Managing spinal deformities in young children is challenging, particularly early-onset scoliosis (EOS). Any progressive spinal deformity particularly in early life presents significant health risks for the child and a challenge for the treating surgeon. Surgical intervention is often required if EOS has been unresponsive to conservative treatment particularly with rapidly progressive curves. An emerging treatment option particularly for EOS is fusionless scoliosis surgery. Similar to bracing this surgical option potentially harnesses growth, motion and function of the spine along with correcting spinal deformity. Dual growing rods is one such fusionless treatment, which aims to modulate growth of the vertebrae. The aim of this study was to ascertain the extent to which semi-constrained growing rods (Medtronic, Memphis, TN) with a telescopic sleeve component, reduce rotational constraint on the spine compared with standard rigid rods and hence potentially provide a more physiological mechanical environment for the growing spine. METHODS Six 40-60kg English Large White porcine spines served as a model for the paediatric human spine. Each spine was dissected into 7 level thoracolumbar multi-segment unit (MSU) spines, removing all non-ligamentous soft tissues. Appropriately sized semi-constrained growing rods and rigid rods were secured by multi-axial screws (Medtronic) prior to testing in alternating sequences for each spine. Pure nondestructive moments of +/4Nm at a constant rotation rate of 8deg/s was applied to the mounted MSU spines. Displacement of each level was captured using an Optotrak (Northern Digital Inc, Waterloo, ON). The range of motion (ROM), neutral zone (NZ) size and stiffness (Nm/deg) were calculated from the Instron load-displacement data and intervertebral ROM was calculated through a MATLAB algorithm from Optotrak data. RESULTS Irrespective of sequence order rigid rods significantly reduced the total ROM (deg) than compared to semi-constrained rods (p<0.05) and resulted in a significantly stiffer (Nm/deg) spine for both left and right axial rotation testing (p<0.05). Analysing the intervertebral motion within the instrumented levels, rigid rods showed reduced ROM (Deg) than compared to semi-constrained growing rods and the un-instrumented (UN-IN) test sequences. CONCLUSION The semi-constrained growing rods maintained rotation similar to UN-IN spines while the rigid rods showed significantly reduced axial rotation across all instrumented levels. Clinically the effect of semi-constrained growing rods evaluated in this study is that they will allow growth via the telescopic rod components while maintaining the axial rotation ability of the spine, which may also reduce the occurrence of the crankshaft phenomenon.

Organisations employ Enterprise Social Networks (ESNs) (such as Yammer) expecting better intra-organisational communication and collaboration. However, ESNs are struggling to gain momentum and wide adoption among users. Promoting user participation is a challenge, particularly in relation to lurkers – the silent ESN members who do not contribute any content. Building on behaviour change research, we propose a three-route model consisting of the central, peripheral and coercive routes of influence that depict users’ cognitive strategies, and we examine how management interventions (e.g. sending promotional emails) impact users’ beliefs and (consequent) posting and lurking behaviours in ESNs. Furthermore, we identify users’ salient motivations to lurk or post. We employ a multi-method research design to conceptualise, operationalise and validate the research model. This study has implications for academics and practitioners regarding the nature, patterns and outcomes of management interventions in prompting ESN.

External stimulus/loading initiates adaptations within skeletal muscle. It has been previously found that the cervical area has the highest loading while performing flying maneuvers under +Gz. The first purpose of this study was to examine the neck muscle response to the physical environment associated with flight training, incorporating limited exposure to +Gz force, in a Pilatus PC-9 aircraft. The second purpose was to examine the short-term range of movement (ROM) response to flight training. Isometric cervical muscle strength and ROM was monitored in 9 RAAF pilots completing an 8-mo flight-training course at Pearce Airbase in Western Australia, and in 10 controls matched for gender, age, height, and weight. Isometric cervical muscle strength and ROM were measured at baseline and at 8 mo using the multi-cervical rehabilitation unit (Hanoun Medical, Downsview, Ontario, Canada). Results indicated that an increase in pilot neck strength was limited to flexion while in a neutral position. No strength changes were recorded in any other site in the pilots or for the controls. These findings suggest that short-term exposure to the physical environment associated with flight training had a limited significant effect on increasing isometric cervical muscle strength. No significant changes were observed in pilot ROM, indicating that short-term exposure to flight does not effect ROM.

The objectives of this study were to determine the impact of different instructional constraints on standing board jump (sbj) performance in children and understand the underlying changes in emergent movement patterns. Two groups of novice participants were provided with either externally or internally focused attentional instructions during an intervention phase. Pre- and post-test sessions were undertaken to determine changes to performance and movement patterns. Thirty-six primary fourth-grade male students were recruited for this study and randomly assigned to either an external, internal focus or control group. Different instructional constraints with either an external focus (image of the achievement) or an internal focus (image of the act) were provided to the participants. Performance scores (jump distances), and data from key kinematic (joint range of motion, ROM) and kinetic variables (jump impulses) were collected. Instructional constraints with an emphasis on an external focus of attention were generally more effective in assisting learners to improve jump distances. Intra-individual analyses highlighted how enhanced jump distances for successful participants may be concomitant with specific changes to kinematic and kinetic variables. Larger joint ROM and adjustment to a comparatively larger horizontal impulse to a vertical impulse were observed for more successful participants at post-test performance. From a constraints-led perspective, the inclusion of instructional constraints encouraging self-adjustments in the control of movements (i.e., image of achievement) had a beneficial effect on individuals performing the standing broad jump task. However, the advantage of using an external focus of attentional instructions could be task- and individual-specific.

The Ph.D. thesis discusses the monetary development in Roman Syria and Judaea in the Late Republican and the Early Imperial Period, from a numismatic, archaeological and historical point of view. In effect, the work focuses on the 1st century B.C. to the 1st century A.D., that is, the assumed time of introduction of Roman denarii to the region. The work benefits from the silver coin hoards of Khirbet Qumran recently published by the author. Though discovered as early as 1955 at Qumran, where the famous Dead Sea Scrolls had been found prior to that in 1947, most hoards remained unpublished until 2007. A second important source utilized is the so-called Tax Law from Palmyra in Syria. Its significance lies in the fact that Palmyra used to be one of the most important cities on the Silk Road, along which luxury goods were transported into the Roman Empire and Rome itself. During the research conducted, studies of the provincial coinage of Judaea (A.D. 6-66) shed new light on the authority of the Roman governors in economic and monetary matters in eastern Mediterranean regions. Furthermore, a new suggestion as to the length of the mandate period of Pontius Pilate is made. The extent of Emperor Augustus monetary reforms as well as the military history of Judaea are discussed in the light of new analytical studies, which show that the production of Roman base metal coins appears to have been a highly controlled process, contrary to popular opinion. Statistical calculations related to the coin alloy revealed striking similarities with Roman and other local metalwork found in Israel; a fact previously unknown. Results indicate that both Roman and local metalwork consisted of outstandingly systematized practises and may have exploited the same metal sources. Information: Kenneth Lönnqvist (*25.7.1962) has studied at the University of Helsinki since 1981. Furthermore, Lönnqvist has lived in the Mediterranean countries and the Near East, and made research there at various scientific institutions and universities for ca. 7 years.

Tutkielmassani käsittelen ranskalaisen säveltäjän Olivier Messiaenin (1908-1992) synestesiaan liittyvää harmonista ajattelua. Messiaen oli ääni-väri -synesteetikko, toisin sanoen hän näki kuulemansa musiikin väreinä. Tältä pohjalta hän kehitti monimutkaisten sointujen ja asteikkojen järjestelmän, jonka puitteissa hän pystyi ikään kuin maalaamaan musiikillaan haluamansa värit. Esittelen aluksi tämänhetkistä synestesiatutkimusta lähinnä kolmen vallitsevassa asemassa olevan päälinjan pohjalta. Näitä edustavat yhdysvaltalainen Richard Cytowic, britti Simon Baron-Cohen ja saksalainen Hinderk Emrich. Käyn läpi heidän määritelmänsä synestesiasta ja näkemyksiään synesteettisistä säveltäjistä. Messiaen on jossain määrin tuonut esiin musiikkinsa värejä lähes uransa alusta lähtien, mutta huomiot ovat yleensä olleet melko ylimalkaisia ja epäjärjestelmällisiä. Tuon esiin näitä eri lähteistä löytyneitä Messiaenin näkemyksiä ja kokemuksia tarkasteltuna Messiaenin henkilökohtaisen sävellysfilosofian pohjalta sekä tiettyihin Messiaenin sävellyksiin ja niiden harmonisiin rakenteisiin liittyen. Messiaenin kuoleman jälkeen vuosina 1994-2002 julkaistun seitsenosaisen teossarjan Traité de rythme, de couleur, et d'ornitologie viimeisessä osassa Messiaen esittää järjestelmällisesti kaikkien erikoissointujensa ja moodiensa värityksen. Tarkastelen Messiaenin käyttämiä harmonioita jakamalla ne yleisiin ja erikoissointuihin sekä moodeihin. Määritellessäni näitä harmonioita käytän metodina sävelluokkajoukkojen teoriaa, jonka avulla kaikki sävelyhdistelmät voidaan määritellä yksiselitteisesti. Esittelen joukkoteoriaa ja siihen liittyviä käsitteitä siinä määrin kuin se liittyy tutkielmaani, enkä siis yritäkään tuoda esiin analyysimetodia koko laajuudessaan. Olen rekonstruoinut visuaalisesti Messiaenin käyttämät noin 150 harmonista väriä, ja tutkielmani liitteenä olevalla CD-romilla esitän ne soivassa ja näkyvässä muodossa. Tällä CD-romilla on myös analyysiMessiaenin urkuteoksen Méditations sur le mystère de la Sainte Trinité 5. osan alusta, jossa tutkin käytännön tasolla värien ilmenemistä Messiaenin musiikissa. Tutkielmani keskeinen osa onkin tämä CD-rom, ja siitä ilmennee myös tutkielmani lähtökohta ja tavoite: luoda työkalu Messiaenin musiikin värisisältöjen hahmottamiseen.

In the 1990 s the companies utilizing and producing new information technology, especially so-called new media, were also expected to be forerunners in new forms of work and organization. Researchers anticipated that new, more creative forms of work and the changing content of working life were about to replace old industrial and standardized ways of working. However, research on actual companies in the IT sector revealed a situation where only minor changes to existing organizational forms were seen .Many of the independent companies faced great difficulties trying to survive the rapid changes in the products and production forms in the emerging field. Most of the research on the new media field has been conducted as surveys, and an understanding of the actual everyday work process has remained thin. My research is a longitudinal study of the early phases of one new media company in Finland. The study is an analysis of the challenges the company faced in a rapidly changing business field and the attempts to overcome these challenges. The two main analyses in the study focus on the developmental phases of the company and the disturbances in the production process. Based on these analyses, I study changes and learning at work using the methodological framework of developmental work research. Developmental work research is a Finnish variant of the cultural-historical activity theory applied to the study of learning and transformations at work. The data was gathered over a three-year period of ethnographic fieldwork. I documented the production processes and everyday life in the company as a participant observer. I interviewed key persons, video and audio-taped meetings, followed e-mail correspondence and collected various documents, such as agreements and memos. I developed a systematic method for analyzing the disturbances in the production process by combining the various data sources. The systematic analysis of the disturbances depicted a very complex and only partly managed production process. The production process had a long duration, and no single actor had an understanding of it as a whole. Most of the disturbances had to do with the customer relationships. The nature of the disturbances was latent; they were recognized but not addressed. In the particular production processes that I analyzed, the ending life span of a particular product, a CD-ROM, became obvious. This finding can be interpreted in relation to the developmental phase of the production and the transformation of the field as a whole. Based on the analysis of the developmental phases and the disturbances, I formulate a hypothesis of the contradictions and developmental potentials of the activity studied. The conclusions of the study challenge the existing understanding of how to conceptualize and study organizational learning in production work. Most theories of organizational learning do not address qualitative changes in production nor historical challenges of organizational learning itself. My study opens up a new horizon in understanding organizational learning in a rapidly changing field where a learning culture based on craft or mass production work is insufficient. There is a need for anticipatory and proactive organizational learning. Proactive learning is needed to anticipate the changes in production type, and the life cycles of products.

The microcommands constituting the microprogram of the control memory of a microprogrammed processor can be partitioned into a number of disjoint sets. Some of these sets are then encoded to minimize the word width of the ROM storing the microprogram. A further reduction in the width of the ROM words can be achieved by a technique known as bit steering where one or more bits are shared by two or more sets of microcommands. These sets are called the steerable sets. This correspondence presents a simple method for the detection and encoding of steerable sets. It has been shown that the concurrency matrix of two steerable sets exhibits definite patterns of clusters which can be easily recognized. A relation "connection" has been defined which helps in the detection of three-set steerability. Once steerable sets are identified, their encoding becomes a straightforward procedure following the location of the identifying clusters on the concurrency matrix or matrices.

This study analyses Augustine s concept of concupiscentia, or evil desire (together with two cognate terms, libido and cupiditas) in the context of his entire oeuvre. By the aid of systematic analysis, the concept and its development is explored in four distinct ways. It is claimed that Augustine used the concept of concupiscentia for several theological purposes, and the task of the study is to represent these distinct functions, and their connections to Augustine s general theological and philosophical convictions. The study opens with a survey on terminology. A general overview of the occurrences of the negatively connoted words for desire in Latin literature precedes a corresponding examination of Augustine s own works. In this introductory chapter it is shown that, despite certain preferences in the uses of the words, a sufficient degree of synonymy reigns so as to allow an analysis of the concept without tightly discriminating between the terms. The theological functions of concupiscentia with its distinct contexts are analysed in separate chapters. The function of concupiscentia as a divine punishment is explored first (Ch 3). It is seen how Augustine links together concupiscentia and ideas about divine justice, and finally suggests that in the inordinate, psychologically experienced sexual desire, the original theological disobedience of Adam and Eve can be perceived. Augustine was criticized for this solution already in his own times, and the analysis of the function of concupiscentia as a divine punishment ends in a discussion on the critical response of punitive concupiscentia by Julian of Aeclanum. Augustine also attached to concupiscentia another central theological function by viewing evil desire as an inward originating cause for all external evil actions. In the study, this function is analysed by surveying two formally distinct images of evil desire, i.e. as the root (radix) of all evil, and as a threefold (triplex) matrix of evil actions (Ch 4). Both of these images were based on a single verse of the Bible (1 Jn 2, 16 and 1 Tim 6, 10). This function of concupiscentia was formed both parallel to, and in answer to, Manichaean insights into concupiscentia. Being familiar with the traditional philosophical discussions on the nature and therapy of emotions, Augustine situated concupiscentia also into this context. It is acknowledged that these philosophical traditions had an obvious impact into his way of explaining psychological processes in connection with concupiscentia. Not only did Augustine implicitly receive and exploit these traditions, but he also explicitly moulded and criticized them in connection with concupiscentia. Eventually, Augustine conceives the philosophical traditions of emotions as partly useful but also partly inadequate to deal with concupiscentia (Ch 5). The role of concupiscentia in connection to divine grace and Christian renewal is analysed in the final chapter of the study. Augustine s gradual development in internalizing the effects of concupiscentia also into the life of a baptized Christian are elucidated, as are the strong limitations and mitigations Augustine makes to the concept when attaching it into the life under grace (sub gratia). A crucial part in the development of this function is played by Augustine s changing interpretation of Rom 7, and the way concupiscentia appears in Augustine s readings of this text is therefore also analysed. As a result of the analysis of these four distinct functions and contexts of concupiscentia, it is concluded that Augustine s concept of concupiscentia is fairly tightly and coherently connected to his views of central theological importance. Especially the functions of concupiscentia as a punishment and the function of concupiscentia in Christian renewal were both tightly interwoven into Augustine s view of God s being and God s grace. The study shows the importance of reading Augustine s discussions on evil desire with a constant awareness of their role in their larger context, that is, of their function in each situation. The study warns against too simplistic and unifying readings of Augustine s concupiscentia, emphasizing the need to acknowledge both the necessitating, sinful aspects of concupiscentia, and the domesticated features of concupiscentia during Christian renewal.

Tutkielmassa tarkasteltiin sukupuolen sosiaalista rakentumista väkivaltaa käsittelevissä kertomuksissa. Aineistona oli 31 lehti-ilmoituksella kerättyä väkivaltakertomusta, joissa väkivallasta kirjoitettiin sekä väkivallan uhrin että tekijän positiosta käsin. Tarkoituksena oli tutkia, millä tavoin väkivaltaa konstruoidaan kertomuksissa ja miten tämä yhdistyy kirjoittajien sukupuolen suorittamiseen. Analyysimenetelmänä oli diskurssianalyysi, jossa sovellettiin sekä poststrukturalistisen diskurssianalyysin että diskursiivisen psykologian lähestymistapaa. Aineistosta oli löydettävissä yhteensä yhdeksän erilaista väkivaltakonstruktiota. Miehen toiseen mieheen kohdistaman väkivallan kontekstissa väkivaltaa konstruoitiin kolmessa konstruktiossa oikeutetuksi ja kahdessa paheksuttavaksi. Parisuhdeväkivallan ja perheessä lapsiin kohdistuvan väkivallan kontekstissa väkivalta näyttäytyi joko väkivallan tekijään liittyvänä, valta-aseman vahvistamisena tai osapuolten vuorovaikutukseen liittyvänä. Tämän lisäksi kaikissa konteksteissa väkivaltaa konstruoitiin toisinaan väkivallan tekijän ulkoisista syistä aiheutuvaksi. Sukupuolen suorittaminen käsitettiin tutkielmassa asemointipyrkimyksinä sukupuolen mukaisiin subjektipositioihin. Kirjoittajien katsottiin kohtaavan väkivaltaan ja sukupuoleen liittyviä diskursiivisia ristiriitoja, joita he pyrkivät neuvottelemaan käyttäen erilaisia neuvottelustrategioita. Väkivaltaan ja maskuliinisuuteen liittyviä diskursiivisia ristiriitoja pyrittiin neuvottelemaan sosiaalisen paheksunnan välttämiseen ja maskuliinisuuden todistamiseen käytetyillä neuvottelustrategioilla. Uhriuteen ja feminiinisyyteen liittyviä diskursiivisia ristiriitoja neuvoteltiin uhriuden todistamiseen sekä sille vastakohtaisesti uhriuden välttelyyn käytetyillä neuvottelustrategioilla, joiden tulkittiin liittyvän pyrkimyksiin asemoitua vahvan naisen positioon. Keskeisinä neuvottelustrategioina olivat erilaiset eronteot, esimerkiksi oikeutetun ja paheksuttavan väkivallan välille, uhrin ja tekijän välille sekä itsen välille ennen ja nyt.
