description: Wir gehen in diesem Artikel der Frage nach, ob sich im Zuge von Globalisierungsprozessen der letzten Jahrzehnte die Nachfrage nach transnationalem Humankapital (Fremdsprachenkenntnisse, interkulturelle Kompetenzen und Wissen über andere Länder und Gesellschaften) am deutschen, niederländischen und britischen Arbeitsmarkt verändert hat. Auf der Grundlage einer systematischen Inhaltsanalyse von Stellenanzeigen in regionalen und überregionalen Tageszeitungen und von Eurobarometerdaten kann gezeigt werden, dass die Nachfrage nach transnationalem Humankapital besonders in der Form von Fremdsprachenkenntnissen im Zeitverlauf zugenommen hat. Sie ist besonders hoch in hochqualifizierten Dienstleistungsberufen. Zugleich zeigen sich deutliche Länderunterschiede in der Arbeitsmarktnachfrage nach transnationalem Humankapital, die durch den Globalisierungsgrad eines Landes und den Verbreitungsgrad der Landessprache plausibilisiert werden können. Allerdings stößt die Validität einer Stellenanzeigenanalyse zur Ermittlung von Qualifikationsanforderungen am Arbeitsmarkt an ihre Grenzen, wenn bestimmte Kompetenzen in einer Gesellschaft als zunehmend selbstverständlich erachtet werden, wie heutzutage z.B. die Englischkompetenz. Insgesamt können wir jedoch zeigen, dass der Besitz von transnationalem Humankapital zu einer wichtigen Qualifikation am Arbeitsmarkt geworden ist.
description: In this article, we analyse how globalisation has changed the demand for transnational human capital (i.e. foreign language skills, intercultural competences and knowledge about other countries and societies) on the German, Dutch and British labour markets over time. Based on a systematic content analysis of job advertisements in local and national daily newspapers, as well as on Eurobarometer data, we can show that the demand for transnational human capital, especially in the form of foreign language skills, has increased in recent decades. This holds true particularly for high‐skilled jobs in the service sector. Moreover, there are significant country differences in the labour market demand for transnational human capital, which can be explained by a country’s level of globalisation and the global diffusion of its national language. However, job advertisements are not always a valid indicator to determine labour market demand for certain qualifications which are increasingly taken for granted in a society, e.g. English language skills. Nevertheless, we can show that the possession of transnational human capital has indeed become an important asset on the labour market.
Development and optimization of innovative analytical methods for the determination of phytoestrogens in soy-food by chromatographic techniques coupled to mass spectrometry
Creators: name: BENEDETTI, BARBARA
Publisher: name: Universit� degli studi di Genova
Year: 2019

description: The present PhD thesis deals with the development and optimization of different analytical methods, which combines powerful instrumental techniques and innovative pre-treatment methods to obtain reliable quantitation. Both gas chromatography and liquid chromatography coupled to mass spectrometry (GC-MS and LC-MS) were applied for the determination of specific analytes in several matrices.
In particular, the main focus was on the quantitation of phytoestrogens in soy-based food matrices. These compounds are interesting because of their endocrine disrupting potential, and their accurate determination is necessary in ?non-traditional? foods which are new on the market, especially in Italy. The instrumental analysis of these compounds was optimized by accurate studies of the different parameters involved in GC-MS and LC-MS analyses, in order to obtain maximum sensitivity, specificity and reproducibility. Optimization of the sample preparation was another fundamental aspect of the work and was carried out by exploiting the chemometric approach of experimental design.
Alongside the main topic of phytoestrogens quantitation in food matrices, an environmental study was performed and dealt with the development of an innovative extraction method for the determination of a class of contaminants (polycyclic aromatic hydrocarbons) in sea water.
A range of preparative and instrumental techniques were studied, compared and applied to environmental and food samples; analytical performances were assessed for all the developed methods and compared with the available literature.
'Now I know how to cope with it': The Trajectory of the Self Over Time in Depression and Anxiety
Creators: name: Mathews, Stephanie
Publisher: name: Swinburne
Year: 2024

description: This research examined how individuals with a depressive and/or anxiety disorder perceive the self over time. Anxiety was associated with helpful comparisons between past, present and future selves. People perceived an upward trajectory of their ability to cope with their symptoms. In contrast, depression onset appeared to disrupt the upward trajectory. People tended to make unhelpful comparisons between the present symptomatic self and the self prior to symptom onset. However, improvement was perceived when comparing the past symptomatic self and current self. The results highlight the importance for treatment to reinforce the upward coping trajectory and target unhelpful temporal comparisons.
Mycorrhizal responsiveness of cultivars and wild varieties of switchgrass, Panicum virgatum L.
Creators: name: Georgeff, Jennifer.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2001
Subjects: subject: Agriculture, Agronomy.

description: This study focuses on switchgrass, Panicum virgatum L., a North American tallgrass prairie species that has been used in agriculture for only 50 years. We hypothesized that wild variants of this species are more mycorrhizal dependent than the cultivars due to selection against mycorrhizae in agricultural conditions. Mycorrhizae, naturally occurring associations between roots and symbiotic fungi, are known to benefit plants in most environments. These associations have been proposed as a means for crop improvement in agriculture. However, current agricultural practices tend to diminish the potential for crops to benefit from mycorrhizae. Two greenhouse experiments with a factorial design were performed using switchgrass inoculated or not with Glomus intraradices Schenck and Smith. In the first experiment, four wild varieties (PH, ONP, Ojibway and Pterophylla) and six cultivars (Forestburg, Summer, Shelter, Caddo, NU and Trailblazer) were grown for 12 weeks. From those, 3 wild types (PH, ONP and Ojibway) and 3 cultivars (Forestburg, Caddo and NU) were chosen for the second experiment. Switchgrass plants were analyzed for various physiological, root and mineral parameters in order to assess their overall mycorrhizal dependency (MD). (Abstract shortened by UMI.)

description: Background Every year, over 1 million people develop isoniazid (INH) resistant tuberculosis (TB). Yet, the optimal treatment regimen remains unclear. Given increasing prevalence, the clinical efficacy of regimens used by physicians is of interest. This study aims to examine treatment outcomes of INH resistant TB patients, treated under programmatic conditions in British Columbia, Canada. Methods Medical charts were retrospectively reviewed for cases of culture-confirmed INH mono-resistant TB reported to the BC Centre for Disease Control (BCCDC) from 2002 to 2014. Treatment regimens, patient and strain characteristics, and clinical outcomes were analysed. Results One hundred sixty five cases of INH mono-resistant TB were included in analysis and over 30 different treatment regimens were prescribed. Median treatment duration was 10.5 months (IQR 9–12 months) and treatment was extended beyond 12 months for 26 patients (15.8%). Fifty six patients (22.6%) experienced an adverse event that resulted in a drug regimen modification. Overall, 140 patients (84.8%) had a successful treatment outcome while 12 (7.2%) had an unsuccessful treatment outcome of failure (n = 2; 1.2%), relapse (n = 4; 2.4%) or all cause mortality (n = 6; 3.6%). Conclusion Our treatment outcomes, while consistent with findings reported from other studies in high resource settings, raise concerns about current recommendations for INH resistant TB treatment. Only a small proportion of patients completed the recommended treatment regimens. High quality studies to confirm the effectiveness of standardized regimens are urgently needed, with special consideration given to trials utilizing fluoroquinolones.

description: The following paper presents results from a longitudinal study on the use of ICT for B2B-related business processes in large Swiss companies. In an empirical survey, 68 questionnaires were personally collected from procurement heads and subsequently analysed. The findings show that reduction of purchase prices is the top priority when goal-setting in procurement. Electronic orders and invoices are the business documents that are most often exchanged electronically between partners. Electronic exchange of invoices (e-invoicing) is a current key topic for over 70 % of the companies. Procurement heads sense a lack of supplier involvement which makes the realisation of balanced B2B solution scenarios difficult. The study shows that IT, without doubt, plays a significant role in everyday procurement, but that the expectations of IT are rarely completely fulfilled.
Investigation of Cementitious Materials for Powder-based 3D Printing
Creators: name: Xia, Ming
Publisher: name: Swinburne
Year: 2024

description: 3D concrete printing is an emerging technology that is set to revolutionize the construction industry by allowing `free-form' construction without the use of expensive formwork. Powder-based 3D concrete printing is one of such techniques, which is capable of producing building components with significantly high resolution. One of the main challenges of this technique is the very limited scope of printable cementitious materials that can be used for construction applications. This doctoral research aims to overcome the issues and barriers by developing a systemic methodology to adapt conventional construction materials to the powder-based 3D concrete printing technique.

description: Länder unterscheiden sich nicht nur in ihrer ökonomischen Stärke und politischen Macht, sondern auch in dem Ansehen bzw. dem ihnen zugeschriebenem symbolischen Kapital. Mit Bezugnahme auf die Literatur zu symbolischen Grenzziehungsprozessen untersuchen wir, in welchem Maße sich in einer multinational zusammengesetzten Schule die nationale Herkunft der Schüler auf die symbolischen Grenzen zwischen den Schülergruppen auswirkt. Empirische Grundlage der Untersuchung bilden qualitative Gruppeninterviews mit Schülerinnen einer Europäischen Schule in Brüssel. Wir können zeigen, dass symbolische Grenzziehungsprozesse in zwei Schritten erfolgen. Zunächst klassifizieren die Schülerinnen ihre Mitschülerinnen anhand jugendspezifischer Kategorien. Dazu gehören (a) ein spezifischer jugendkultureller Lebensstil, (b) gute Schulleistungen ohne Überambition, (c) kosmopolitische Werthaltungen und schließlich (d) die Zugehörigkeit zu einer dominanten Sprachengruppe. Diese Primärkategorisierungen werden dann in einem zweiten Schritt auf unterschiedliche nationale Herkunftsgruppen attribuiert. Auf diesem Wege entsteht eine Statushierarchie zwischen den Ländern, vor allem zwischen nord- westeuropäischen und osteuropäischen Ländern.
Nationalist terrorism and political parties: The challenge to liberal democracies.
Creators: name: Gratton, Philippe J.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1997
Subjects: subject: Political Science, General.

description: This thesis explores the relationship between terrorist groups and their political counterparts. It finds that changes in world events have allowed terrorist groups to include legitimate political participation as part of their overall strategy. It is proposed that some groups, while not completely abandoning their terrorist activities, come to realize the potential behind legitimate political participation, and adapt accordingly. This not only holds important consequences for the terrorists, but also for the liberal democracies that are host to their actions. Two known terrorist groups are compared--the Irish Republican Army and the Palestinian Liberation Organization--in order to demonstrate how they are evolving towards legitimate political participation. One important realization is that such a move towards legitimacy is not always a unidirectional movement; therefore, groups may waver back and forth from legitimacy to subversion. The implications for liberal democracies are also examined. While these countries have been remarkably resilient in dealing with the terrorist threat, the acceptance to negotiate suggests that some changes have been effected on the host countries' regimes.

description: DYNAMO is a multi-wavelength, spatially-resolved survey of local (z 0:1) star-forming galaxies designed to study evolution through comparison with samples at z ' 2. Half of the sample has integrated H luminosities of > 1042 erg/s, the typical lower limit for resolved spectroscopy at z~2. The sample covers a range in stellar mass (109-1011 Msun) and star-formation rate (0.2-100 Msun/yr). In this first paper of a series, we present integral-field spectroscopy of H-alpha emission for the sample of 67 galaxies. We infer gas fractions in our sample as high as ~0.8, higher than typical for local galaxies. Gas fraction correlates with stellar mass in galaxies with star-formation rates below 10 Msun/yr, as found by COLDGASS, but galaxies with higher star-formation rates have higher than expected gas fractions. There is only a weak correlation, if any, between gas fraction and gas velocity dispersion. Galaxies in the sample visually classified as disc-like are offset from the local stellar-mass Tully-Fisher relation to higher circular velocities, but this offset vanishes when both gas and stars are included in the baryonic Tully-Fisher relation. The mean gas velocity dispersion of the sample is ~50 km/s, and V/sigma ranges from 2 to 10 for most of the discs, similar to 'turbulent' galaxies at high redshift. Half of our sample show disc-like rotation, while ~20 percent show no signs of rotation. The division between rotating and non-rotating is approximately equal for the sub-samples with either star-formation rates > 10 M yr⊙1, or specific-star-formation rates typical of the star-formation ‘main sequence' at star-formation rates > 10 M yr⊙1, or specific-star-formation rates typical of the star-formation ‘main sequence' at z ' 2. Across our whole sample, we find good correlation between the dominance of ‘turbulence' in galaxy discs (as expressed by V= ) and gas fraction as has been predicted for marginally stable Toomre discs. Comparing our sample with many others at low- and high-redshift reveals a correlation between gas velocity dispersion and star formation rate. These findings suggest the DYNAMO discs are excellent candidates for local galaxies similar to turbulent z ' 2 disc galaxies.
PROBLEMI COSTITUZIONALI IN TEMA DI ALIMENTAZIONE E DIRITTO AL CIBO ADEGUATO

description: La centralit� del ruolo dell?alimentazione nelle vicende umane � un dato notorio, che accomuna epoche e culture diverse fra loro.
Quello tra uomo e cibo � un rapporto atavico che attiene alla soddisfazione di una necessit� biologica primaria, la quale diventa a sua volta premessa e fondamento per la realizzazione di tutte le ulteriori esigenze umane, fisiche e spirituali.
Intorno al cibo ruota un microcosmo di usi, costumi, culti e tradizioni, tutti fenomeni umani scanditi e accompagnati da altrettanti riti alimentari.
A sua volta, l?alimentazione � sempre stata vista come esigenza fondamentale delle comunit�. Uno tra i pi� rilevanti e primitivi fattori di coesione sociale degli individui in comunit�: cibo e ricerca della protezione.
V?� dunque un legame profondo tra cibo, individuo e societ� che non sfugge alla storia, all?antropologia e alla sociologia, e che presenta significativi elementi di rilevanza anche per il diritto.
Ed invero, il diritto dell?alimentazione rappresenta un settore di indagine giuridica in via di sviluppo, con un vivo dibattito in dottrina (specie a seguito dell?EXPO di Milano del 2015) e con numerosi elementi di interesse.
Nondimeno, molti restano gli elementi dubbi e critici di una branca del diritto che non � a tutti gli effetti materia giuridica e presenta elementi per certi versi compositi e frammentari ed una marcata tendenza alla multidisciplinariet� e alla specialit�.
Rispetto alle predette considerazioni, alcuni autori hanno avanzato interessanti suggestioni da un lato, circa i profili di rilevanza per il diritto costituzionale del diritto dell?alimentazione e, dall?altro, in merito al contributo che la dottrina costituzionalistica pu� apportare rispetto allo sviluppo teorico di una materia di diritto dell?alimentazione ed al fine di ovviare ad alcune delle criticit� dell?attuale disciplina giuridica dell?alimentazione, fra cui la parcellizzazione e la scarsa effettivit� di determinate previsioni.

description: Herpes Simplex Virus Type 2 (HSV-2) causes genital herpes and induces latency in nerve cells. Acyclovir is a guanosine analogue widely used for HSV-2 treatment. By investigating the effect of acyclovir and HSV-2 infection on gene expression, a number of genes that may be candidates for therapeutic targets of HSV-2 were identified. HSV-2 was used to infect IMR-32 human neuroblastoma cells for 4 hours in the presence of acyclovir. RNA was extracted, and used as a template for both reverse transcriptase-polymerase chain reaction (RT-PCR)s using either 32P for filter microarray or fluorescent labels for glass slide microarray. Filter microarrays were spotted with 375 immune genes; glass slides were spotted with 19 000 human genes and expression sequence tags. IMR-32 cells were exposed to acyclovir for 4 hours, RT-PCR was performed with 32P, and the labeled product was hybridized with microarray filters spotted with 375 immune genes. IMR-32 cells were infected with HSV-2 and incubated for 4 hours at either 37°C for productive infection or 40°C for latent infection. Two methods of analysis were performed on filter microarrays. The effects of acyclovir were investigated as a control for the HSV-2 experiments. (Abstract shortened by UMI.)

description: Die Rückführung von Geflüchteten in ihre Herkunftsländer ist in vielen europäischen Ländern zu einem kontroversen politischen Thema geworden. Auf der Grundlage einer in 13 Mitgliedsländern der Europäischen Union durchgeführten Umfrage analysieren wir zum einen, ob die Bürgerinnen und Bürger Europas der Ansicht sind, dass Geflüchtete in ihre Herkunftsländer zurückgeführt werden sollen, wenn der Grund für die Flucht obsolet geworden ist und zum anderen wie man Unterschiede in der Einstellung zur Rückführung von Geflüchteten erklären kann. Eine deutliche Mehrheit aller Befragten (70 %) spricht sich für eine Rückführung von Geflüchteten aus. Dies gilt auch für diejenigen, die sich für eine Aufnahme von in Not befindlichen Geflüchteten aussprechen. Das geltende Recht – Aufnahme von Geflüchteten, die sich in Not befinden einerseits und Rückführung, wenn der Asylgrund obsolet geworden ist, andererseits – wird von der Mehrheit der Europäer*innen also unterstützt. Zugleich zeigen sich deutliche Unterschiede zwischen den Ländern. Die Ergebnisse multivariater Analysen demonstrieren, dass kulturelle Faktoren sowohl auf Individual- als auch auf Länderebene die Einstellung zur Rückführung beeinflussen, während strukturelle Faktoren, die auf die ökonomische Interessenslage rekurrieren, keinen wesentlichen Erklärungsbeitrag leisten. Die politischen Schlussfolgerungen aus diesem Ergebnis diskutieren wir im letzten Abschnitt des Aufsatzes.
STORIA E STORIOGRAFIA MUSICALE NEL PRIMO PERIPATO
Creators: name: TOCCO, AMBRA
Publisher: name: Universit� degli studi di Genova
Year: 2019

description: The dissertation provides an overall study of history of music as a scholarly discipline
within the early Peripatos, that is, in the writings of Aristotle?s direct and indirect pupils,
dating between the second half of the 4th century BC and the end of the 3rd. It is known
that Aristotle and his pupils were the first who systematically divided the domain of
human knowledge into several distinct disciplines, to be studied with proper methods and
tools; music makes no exception within this general framework. Furthermore, it is still
Aristotle, followed by his disciples, who first develops the idea that the history of a
discipline is intrinsically related to its theoretical study. This aspect proves to be
particularly relevant within the domain of music, as shown by the remnants of Peripatetic
writings devoted to this subject: most of them display an outstanding interest in
understanding and reconstructing music in the past, first and foremost by collecting and
interpreting literary evidence about it. Peripatetic writers also seem to be deeply
influenced by the Aristotelian teleological conception, according to which every human art
undergoes a diachronic evolution marked by a beginning, a progressive growth until its
own nature is properly fulfilled and, eventually, a degeneration. This general idea proves
to be particularly effective in the scholarly treatment of music by most Peripatetic scholars,
affecting both their research interests (mostly the origins and the development of music
through the archaic and classical eras) and their interpretation of musical changes through
time (especially their severe criticism against the so-�??called ?new music?, a tendency that
takes place from the late 5th century BC onwards). The effectiveness of this historical
paradigm is also confirmed by its reception and exploitation in later sources, among
which the pseudo-�??plutarchaean De musica, which relies heavily on 4th century BC sources.
The structure of the dissertation reproduces the chronological pattern outlined above.
Following a general introduction concerning music in Aristotelian thought and its shaping
as a theoretical discipline within his school, the three parts of the work are devoted each to
a single period of ancient Greek musical history. Part I analyzes evidence about Peripatetic
enquiry into the origins of Greek music, that is, the identification of its ?first discoverers?
(Chapter 1), as well as the reconstruction of a pre-�??Homeric history of epic singing (Chapter
2). Part II is concerned with music in the ?historical? (that is, not mythical or pre-�??historical)
past: Chapter 1 analyzes Peripatetic fragments that attempt at reconstructing lost musical
habits (instruments, songs, dances), whereas Chapter 2 focuses on ?innovations? and
?innovators? during archaic and early classical eras. Eventually, in Part III Peripatetic
evidence about ?new music?, in its aesthetic and ideological implications, is discussed.

description: The Internet of Things (IoT) represents a bright prospect that a variety of common appliances can connect to one another, as well as with the rest of the Internet, to vastly improve our lives. Unique communication and security challenges have been brought out by the limited hardware, low-complexity, and severe energy constraints of IoT devices. In addition, a severe spectrum scarcity problem has also been stimulated by the use of a large number of IoT devices. In this paper, cognitive IoT (CIoT) is considered where an IoT network works as the secondary system using underlay spectrum sharing. A wireless energy harvesting (EH) node is used as a relay to improve the coverage of an IoT device. However, the relay could be a potential eavesdropper to intercept the IoT device’s messages. This paper considers the problem of secure communication between the IoT device (e.g., sensor) and a destination (e.g., controller) via the wireless EH untrusted relay. Since the destination can be equipped with adequate energy supply, secure schemes based on destination-aided jamming are proposed based on power splitting (PS) and time splitting (TS) policies, called intuitive secure schemes based on PS (Int-PS), precoded secure scheme based on PS (Pre-PS), intuitive secure scheme based on TS (Int-TS) and precoded secure scheme based on TS (Pre-TS), respectively. The secure performances of the proposed schemes are evaluated through the metric of probability of successfully secure transmission ( P S S T ), which represents the probability that the interference constraint of the primary user is satisfied and the secrecy rate is positive. P S S T is analyzed for the proposed secure schemes, and the closed form expressions of P S S T for Pre-PS and Pre-TS are derived and validated through simulation results. Numerical results show that the precoded secure schemes have better P S S T than the intuitive secure schemes under similar power consumption. When the secure schemes based on PS and TS polices have similar P S S T , the average transmit power consumption of the secure scheme based on TS is lower. The influences of power splitting and time slitting ratios are also discussed through simulations.
Modelling the muscles of the lower extremity: The effect of varying joint angles on muscle length.

Subjects: subject: Biology, Anatomy.

description: Polynomial regression was used to describe the relationship between lengths of the five muscles of interest and lower extremity joint angle(s). A difference between the genders was observed, so the male and female data were separated and five regression equations (one per muscle) were fitted to each data set. In an attempt to build general regression equations normalization and transformation of the data was performed, but these manipulations of the data did not lead to predictive equations. Addition of leg segment length, for the monoarticular muscles, and height, for the biarticular muscles, as independent variables did significantly increase model fit. The general regression model was quantitatively compared to the leg segment lengths and the actual observed values. It was also qualitatively compared to two other models. Results showed that while the general regression model is good at predicting muscle function, it is not a very accurate predictor of muscle length.

Physical and molecular interactions of different cell types and biomolecules on nanostructured polymeric materials
Creators: name: Nguyen, Huu Khuong Duy
Publisher: name: Swinburne
Year: 2024

description: Polymers play an essential role in biomedical devices. Bacterial contamination on polymeric surfaces hinders the functionality of the device, ultimately leading to its failure. Patients requiring polymeric implantable materials are commonly exposed to a high risk of healthcare associated-infections. Therefore, an in-depth investigation into the interactions taking place at the bio-interfaces of bacterial cells and human proteins on polymeric surfaces is crucial. This work may provide a useful insight towards the development of straightforward, tunable and low-cost microfabrication approaches for the evolving suite of physical anti-biofouling materials that are not reliant on biocidal agents and biocompatible for biomedical applications.
Expression of scinderin in megakaryoblastic leukemia cells induces differentiation, maturation, apoptosis with release of platelet-like particles, and inhibits proliferation and tumorigenesis.

description: Proliferation of atypical megakaryoblasts is a characteristic of megakaryoblastic leukemia. Cell lines established from patients with this disorder show presence of gelsolin but absence of scinderin expression, two filamentous actin severing proteins present in normal megakaryocytes and platelets. Vector-mediated expression of scinderin (pcDNA3-Sc) in the megakaryoblastic cell line MEG-01 induced a decrease in F-actin and gelsolin as evaluated by immunocytochemistry, image analysis and immunoblotting. This was accompanied by an increased Rac2 expression followed by activation of PAK/MEKK.SEK/JNK/c-jun, c-fos and the Raf/MEK/ERK transduction pathways. Transduction pathway activation was responsible for cell differentiation, polyploidization, maturation and apoptosis with release of platelet-like particles. Platelet-like particles expressed surface CD41 a antigen, had dense core vesicles, a high affinity serotonin transport and a circular array of microtubules. Treatment of platelet-like particles with thrombin induced aggregation and release of serotonin. Cell proliferation and the cells' ability to form tumours in nude mice were also inhibited by expression of scinderin. The lack of scinderin expression in megakaryoblastic leukemia cells seems to be responsible for their inability to enter into differentiation and maturation pathways characteristic of their normal counterparts.

description: Das Internet bzw. der darauf aufsetzende multimediale Mehrwertdienst World Wide Web (WWW) wird heute von den meisten Teilen der Wirtschaft als die ?enabling technology? für Anwendungen der elektronischen Geschäftsabwicklung, den ?Electronic Commerce?, betrachtet. Die globalen und heute allgemein verfügbaren Telematikinfrastrukturen auf der Basis des Internet bilden die Grundlage für das Entstehen offener, elektronischer Märkte (EM) [Schmid95a S. 18ff.]. Elektronische Zahlungssysteme sind ein entscheidender Faktor für den Erfolg der elektronischen Geschäftsabwicklung und damit elektronischer Marktplätze. Digitale Zahlungsmittel bilden - analog zu traditionellen Marktplätzen - das Schmiermittel der elektronischen Marktplätze, dem Marketspace. Wirtschaft und Wissenschaft arbeiten heute mit Hochdruck an innovativen Lösungen für die komfortable, sicherere und ökonomische Zahlungsabwicklung in offenen Netzen wie dem Internet.

description: The kinetics of vapour phase hydrodenitrogenation of pyridine over a catalyst containing 0.5% platinum supported in alumina was studied using a fixed-bed catalytic reactor. The effect of process variables such as total reactor pressure, reaction temperature and space time on the conversion of pyridine, organic product distribution, yield of hydrocarbons and selectivity for hydrocarbons was studied. The effect of pressure is more than that of temperature and space time. When the pressure was doubled, the conversion of pyridine increased by 1.3 to four times and the yield and selectivity for hydrocarbons increased many folds. The reaction is believed to proceed via hydrogenation of pyridine to piperidine followed by the ring rupture of piperidine to pentylamine and finally the formation of pentane and ammonia. Pentyl piperidine was a major intermediate found. At higher pressure, ethyl piperidine and traces of cyclopentane were found to be other products. Dipentylamine was another intermediate found at higher pressure. At low pressure, dipentylamine, ethyl piperidine and cyclopentane were not detected. Many rate equations were tried to fit the kinetic data of the hydrodenitrogenation of pyridine. A Langmuir-Hinshelwood type rate expression with a pseudo order rate constant fitted the data best. From the Arrhenius plot of the pseudo rate constants using a lumped parameter theoretical model, the activation energy was estimated to be 19.89 kcal/mol. From the mechanistic model, the ring rupture of piperidine to pentylamine was found to be the rate determining step in the hydrodenitrogenation of pyridine.
Characterization of sigma and phencyclidine binding sites in bovine adrenal medulla.

description: The adrenal medullary sigma and phencyclidine (PCP) receptors have been characterized by radioligand binding studies in bovine adrenal medulla. Using the prototypic sigma receptor ligand ($\sp3$H) (+)SKF-10047, two binding components were revealed, firstly, a high affinity sigma site and secondary, a low affinity "PCP-like" binding site. Investigation of the sigma and PCP-like binding sites in the adrenal medulla using the highly selective sigma ( ($\sp3$H) 3(+)PPP) and phencyclidine receptor ( ($\sp3$H) TCP) ligands has demonstrated that these two binding sites share many similar features. The radioligands ($\sp3$H) 3(+)PPP and ($\sp3$H) TCP saturate a similar maximal population of receptors (B$\sb{\rm max}$ = 218-250 fmol/mg protein) and both are most potently displaced by sigma ligands. Slight differences in stereoselectivity suggest that the binding of ($\sp3$H) TCP and ($\sp3$H) 3(+)PPP may be to multiple subtypes of sigma receptors. Evidence accumulated suggests that a novel peptide from adrenal chromaffin cell granules namely, histogranin, may act as an endogenous ligand for one or both sigma subtypes defined in this study.

description: In the computer area, the term "agent" describes a software entity that performs tasks on behalf of the user. Recently, the mobile agent technology has become an attracting research subject, especially in the field of Distributed Object Technology (DOT), where it is believed that this new paradigm could considerably rectify the shortcomings of its predecessors. As a relatively new concept, the agent technology is still immature, although it is gathering its share of investment money. In our opinion, a major problem still limiting widespread use of mobile agents is the lack for an appropriate supporting platform. The existing agent infrastructures consider differently the issues related to the paradigm; and none comes with a design that appropriately addresses all of them; security being the most poorly treated aspect. This thesis presents our Java-based mobile agent platform called SHIPMAI. The proposed platform aims to efficiently provide all necessary agent services, namely, execution, security, transport, tracking, communication, and persistence. Those MA services are reasonably distributed thanks to the smart agent-space hierarchy introduced by SHIPMAI. Our system architecture consists of private agent domains managed by ADCs (Agent Domain Controllers). Each domain contains several AEEs (Agent Execution Environments), which are destined to host agents. The idea is partially inspired from the Intranet concept. To improve the system flexibility, policies are integrated so as to leverage the functioning of SHIPMAI and to control the behavior of agents. The thesis work includes also the development, on top of SHIPMAI, of a "Mobile Agent-Based Software Distribution" application. MABSD uses agents in order to provide a highly automated delivery and installation of software packages.

description: Die EDEKA Minden-Hannover Holding GmbH (im Weiteren EDEKA) ist Marktführerin in ihrem Absatzgebiet und die bedeutendste EDEKA-Regionalgesellschaft. Innerhalb der EDEKA-Gruppe ist sie der Treiber bei Innovationen. Das Unternehmen wird durch eine Vielzahl an lokalen Lieferanten mit Produkten für den Einzelhandel beliefert. Die Rechnungslegung der Lieferanten erfolgte bis 2006 auf Basis von Papier über den Postweg. Der interne Prozess bei EDEKA war kompliziert, mehrstufig und für die Lieferanten nicht einsehbar. Mit Einführung einer neuen Lösung erfolgt die Rechnungsübermittlung vollautomatisch auf elektronischem Weg und stellt sich für die Lieferanten der EDEKA transparent dar. Der Prozess ist für Lieferanten und für die EDEKA kostengünstiger und die Prozessdurchlaufzeiten konnten verkürzt werden.

description: Die Integration von Informationssystemen ist ein Thema, das in der Literatur schon lange diskutiert wird. Aufgrund der technologischen Entwicklung haben sich die Voraussetzungen für Integration in den letzten Jahren erheblich verbessert. Der vorliegende Beitrag konzentriert sich auf die Integration von Business Software in KMU und zeigt anhand empirischer Primärdaten den aktuellen Stand in der Schweiz auf. Dabei wird unter anderem deutlich, welche Erfahrungen in bisherigen Integrationsprojekten gemacht wurden und welche Anforderungen an zukünftige Business-Software-Lösungen gestellt werden. Es zeigt sich, dass bei einigen Software-Modulen die Intensität der Nutzung und der Grad der Integration von der Unternehmensgrösse abhängig ist.
A pericyclic-based approach to the total synthesis of retigeranic acid A.

description: The preparation of a key synthetic intermediate for the total synthesis of retigeranic acid A (1) through the use an intramolecular Diels-Alder reaction is described. Our approach to retigeranic acid A involved two key building blocks, a trans-hydrindane 52 and a unique tricyclic ketone 51. The building block 52 has been successfully synthesized in the Fallis laboratory, but the synthesis of 51 by an intermolecular Diels-Alder has been difficult. A new route to 51 was devised, involving the use of an intramolecular Diels-Alder reaction. The synthesis started with the preparation of the ketone ester 76 in three steps from commercially available (R)-(+)-pulegone in a 46% yield. Alkylation of 76 with the tosylate 78, followed by oxidative bond cleavage generated the diketone ester 80 in an overall yield of 44%. An intramolecular aldol-condensation and subsequent reduction produced the diol 72. A selective DCC coupling with 2-chlorocrylic acid afforded the dienophile-alcohol 71 in a yield of 46%. A variety of methods were investigated for the dehydation of the alcohol to the diene 70. In the final synthetic route, 71 was quantitatively oxidized with activated MnO$\sb2$ to the ketone 109. The kinetic enolate of 109 was trapped using collidine and triisopropylsilyltrifluoromethanesulfonate, producing the desired diene 110 as a 1:1 mixture. This unstable compound, when heated in a refluxing 10 mole % solution of hydroquinone in benzene, underwent the desired intramolecular Diels-Alder reaction to give the adduct 112 in a yield of 64%.* ftn*Please refer to the dissertation for diagrams.
