description: Druckbare Elektronik, Leichtbauelemente für Autos oder Nanocarrier-Systeme für medizinische Zwecke sind funktionale Materialien, die als wichtige Beispiele für neuartige Materialien gelten. Neuartige Materialien entstehen durch die gezielte Kombination von chemischen Bausteinen, um sehr präzise interne und/oder externe Strukturen und dadurch besondere Eigenschaften und neuartige Funktionen zu erzielen. Sie versprechen ein großes Anwendungspotenzial in verschiedenen Bereichen, zum Beispiel bei erneuerbaren Energien, in der Medizin oder zur Ressourcenschonung. Allerdings lässt sich derzeit nur schwer abschätzen, welche neuartigen Materialien in Zukunft tatsächlich zum Einsatz kommen werden und inwieweit der bestehende rechtliche Rahmen und andere Maßnahmen geeignet sind, um die Sicherheit für Mensch und Umwelt und weitere Aspekte der Nachhaltigkeit von neuartigen Materialien entlang ihres Lebenszyklus zu gewährleisten. Der Artikel stellt Handlungsoptionen aus behördlicher Sicht vor.

description: Printable electronics, lightweight components for cars or nanocarrier systems for medicine are functional materials that are examples of advanced materials. Advanced materials are built up through a targeted combination of chemical building blocks to achieve very precise internal and external structures, and thus feature specific properties and new funtions. Advanced materials promise great application potential in various areas such as renewable energies, health care or resource conservation. However, it is currently difficult to assess which novel materials will be actually used in the future and to what extent the existing legal framework or other measures will be suitable for addressing safety for human and environment as well as aspects of sustainability of advanced materials along their life cycle. To address these questions, option to act from an authority perspective are presented.

description: This dissertation presents results of ethnographic study at a non-religious summer camp called Camp Quest Montana in the summer of 2011 and the numerous insights gained into the lived experiences of non-religious Americans. These particular Americans, because of their non-religion, have experienced unique pressures while navigating through life in a country that is and has been dominated by religious identification and belief. The ethnographic accounts gathered over the course of a week at Camp Quest Montana show how these non-religious people were using a language of belief, informed by a spirituality derived from science, as part of an effort to fit themselves into this wider and religiously steeped American culture. This dissertation argues that the Camp Questers express themselves through a language of “belief” because of the current and historical pressures to be religious, along with Americans’ tendency to distrust non-religious people. Using “belief” language allows them to talk about themselves in a way that makes sense to religious Americans, while also maintaining a non-religious identification. Moreover, this study found differences between how first and second-generation non-religious Americans (the parents and children at Camp Quest Montana) interact with religious Americans. These variations are important because they point to different experiences of the social and cultural landscape of the United States, differences that are reflected in each generation’s non-religious expression. This data also presents a challenge to current arguments regarding the benefits of religion to the socialization and overall well-being of youth.
Mangrove endophytic fungi from Sarawak: isolation of secondary metabolites and optimisation of growth conditions
Creators: name: Lew, Yao Long
Publisher: name: Swinburne
Year: 2024

description: Endophytic fungi are a group of organisms unique in the sense that they live virtually their entire life cycles within the tissues of a host; they have been known to confer beneficial properties to the plants they inhabit in terms of protection from predation and tolerance against abiotic stress. For all their unique properties, much work lies ahead in understanding these innocuous organisms. Mangrove endophytic fungi are the more interesting group within endophytes, this as they have adapted to not only the host plant but the extreme environment those mangrove plants are constantly subjected to. There has been limited work in Malaysia regarding mangrove endophytic fungi, with more focus being given to fungi which are associated to medicinal plants. Nevertheless, significant work has been done by countries which border the South China Sea. These works were reviewed in a bid to understand trends in mangrove endophytic fungi research on a regional scale. During the course of this research mangrove endophytic fungi were subjected to large scale fermentation to isolate natural products, as well as growth optimisation studies to discern the best growth medium for isolation and cultivation of these extreme-tolerant microbes. The well-known antioxidant trans-ferulic acid was successfully isolated from a batch of fermentation products from Phyllosticta-related strain of fungi. It appears to be the first known instance of finding this metabolite with the fungal genus tested. Growth optimisation studies revealed that the growth requirements of each strain of fungi significantly differs from each other. Salinity, nitrogenous compounds, pH, are all important factors to consider when optimising growth of mangrove endophytic fungi. Though the strains tested were limited in number and diversity, it is clear that follow-up studies will be required to reveal more about the growth behaviour of these poorly-studied life forms.

description: A casein phosphopeptide (CPP) fraction derived from tryptic hydrolysis of bovine casein was evaluated for antioxidant activity. Conjugations or mixtures of CPP with polysaccharide, galactomannan (Gal), or xyloglucan (Xyl) were prepared to evaluate potential enhancement of CPP antioxidant activity. The effect of calcium was also investigated. The CPP preparation alone was effective at scavenging hydroxyl radicals and sequestering Fe2+ to protect against Fenton reaction-induced deoxyribose oxidation in non-site-specific (up 63.3% inhibition) and site-specific (up 32.1% inhibition) binding assays, respectively. CPP also effectively quenched 2,2’-azinobis-3-ethylbenzothiazoline-6-sulfonic acid radicals (ABTS•+) to an extent of 67.6% scavenging in an aqueous system. In a soybean lecithin liposome system, CPP exhibited effective protection against peroxyl radical-induced liposomal peroxidation (38.3% of control in terms of rate of propagation). Conjugating CPP with Gal or Xyl polysaccharides using Maillard reaction conditions significantly reduced activity in the Fenton reaction-deoxyribose assays, while exhibiting no effect on the antioxidant activity of native CPP in both the ABTS and liposome assays, respectively. These results represent comparative antioxidant capacity of the native CPP and associated conjugates in phases that varied in relative hydrophilic and hydrophobic character. We conclude that CPP has the potential to act as both a primary and secondary antioxidant by displaying transition metal ion sequestering activity and free radical quenching activity. Improvements in antioxidant activity of CPP by Maillard-type conjugation with Xyl or Gal were relatively small and model-specific.

description: This study sought to examine power, resources and environmental negotiation through an examination of the operations and governance of two Community Sport Organizations (CSOs) located in a mid-sized city in the Midwest region of the United States. This was undertaken by answering three research questions: (1) How does power shape the allocation of resources within CSOs? (2) How do CSOs secure access to resources from their organizational environments? and (3) How do CSOs attempt to manipulate their organizational environment? The dissertation took a case study approach, combining documentary review with in-depth semi-structured interviews to develop a greater understanding of the CSOs under study and of the dynamics of power that animate the organizations’ activities, decisions, and outlook. By using two theories of power, Lukes’ Three Dimensional (3D) approach and Resource Dependence Theory (RDT), the dissertation examined both an institutional and episodic view of power, providing a richer view of power within the organizations under study. In RQ1, the study finds that CSOs are willing to allocate resources to the social construction of their sport; that they are sensitive to threshold effects in resource allocation, meaning they provide resources up to the point that a need is met, and not beyond; and that gender played a role in internal resource allocation. In RQ2, the results indicated that the CSOs under study were able to secure resources from their environments through not valuing their institutional existence, and through working with their multi-level governance structures. RQ3 finds that CSOs used anticipatory compliance with environmental actors and borrowing capacity of means to change their organizational environments. The overall conclusion of the study notes that low organizational capacity in CSOs has considerable benefits to go with the drawbacks previously noted in the CSO and not-for-profit literatures. The study outlines that CSOs are able to use their low capacity status to help ensure their organizational environment remains passive, allowing them to maintain a focus on their members and mission while securing sufficient resources to survive. Further discussion of volunteer leadership being a type of participation in sport and of the challenges of studying CSOs, as well as participant recruitment, are also included.

description: Die zunehmende Einspeisung erneuerbarer Energien (EE) und ein flexibler Einsatz dezentraler Energiesysteme sind zwei wesentliche Stellschrauben für die erfolgreiche Energiewende. Durch einen flexiblen Betrieb dezentraler sektorgekoppelter Energiesysteme (DSE) kann die volatile dargebotsabhängige EE-Einspeisung abgefedert werden. Ein flexibler Betrieb ist auf ein externes Signal ausgerichtet, durch welches das DSE mit dem Strommarkt interagiert, ohne Eingriffe in die Energiebedarfe des DSE vorzunehmen. Ermöglicht wird zugleich ein wirtschaft-licher und emissionsoptimierter Betrieb für die Anlagenbetreiber. Die Arbeit setzt an einer Forschungslücke an, da es derzeit keine allgemeingültige Methode gibt, die den flexiblen Be-trieb eines DSE im Sinne eines marktdienlichen Betriebs zur Unterstützung der EE-Integration quantifizieren kann. Ziel dieser Masterarbeit ist, das Flexibilitätspotenzial eines DSE zu defi-nieren und quantifizieren. Die leitende Forschungsfrage dieser Arbeit lautet: Wie kann die Flexibilität von DSEs quantifiziert werden, um verschiedene DSEs in Bezug auf ihre Flexibilität zu bewerten? Als Grundlage wird die Flexibilität im Allgemeinen und die Flexibilität, die ein DSE bereitstellen kann, charakterisiert. Auf Basis dieser Charakterisierung und einer Literaturrecherche werden die Anforderungen an die Quantifizierungsmethode formuliert und drei Quantifizierungskenn-zahlen entwickelt. Diese können den Betrieb eines DSE über einen Quantifizierungszeitraum wirtschaftlich, emissionstechnisch und hinsichtlich des Flexibilitätseinsatzes für die Residual-lastdeckung quantifizieren. Um den nicht-flexiblen Betrieb gegenüber dem flexiblen Betrieb abzubilden, wird ein Referenzkonzept definiert. Anschließend wird die Anwendung der Quan-tifizierungskennzahlen und die Validierung ihrer Aussagekraft mit einer MILP-Optimierung (Mixed-integer linear programming) für den Betrieb des DSE eines Krankenhauses dargelegt. Die entwickelten Zusammenhänge und Quantifizierungskennzahlen geben DSE-Betreiber*innen und DSE-Entwickler*innen ein Werkzeug an die Hand, um den Betrieb ihres DSE zu bewerten. Die Methode ermöglicht den Vergleich von flexiblem und nicht-flexiblem Betrieb eines DSE in Hinblick auf Kosten, CO2-Emissionen und die Fähigkeit zur Deckung der Residuallast durch Flexibilitätsbereitstellung. Die Ergebnisse zeigen, dass sich der marktdien-liche Betrieb eines DSE, je nach Flexibilisierungsgrad des DSE-Konzepts, auch wirtschaftlich und emissionsseitig lohnt. Demzufolge kann ein flexibel betriebenes DSE die Integration von EE fördern.

description: Due to the greater demand for energy resources, monitoring is now necessary for their responsible and sustainable utilization. Collecting data from electricity meters is a crucial step towards achieving this. In most nations, this operation is completed manually at most once per month due to the limitations relating to cost and time. The average consumption for the preceding months is typically used to estimate and determine the current month's consumption. Due to increased billings that don't correspond to reality, this leads to numerous claims from customers. This project aims to develop an AI-based system that utilizes a cost-effective microcontroller to automate the data collection from electricity meters. The Convolutional Neural Network model developed using a manually constructed dataset serves as the centerpiece of the proposed system. The model's accuracy during the model testing phase was 97.63 %. Without the need for additional algorithms, this system can recognize full digits and intermediate digits (such as 4.5 and 5.5). The proposed system was tested and validated by experiments.

description: We study the phenomenon of controlling the light by light known as the optical bistability for the two-dimensional tilted Dirac system. Using the Boltzmann approach under relaxation time approximation, we find that the optical bistability can be controlled by the nonlinear response of the system. For the prototype, we consider an inversion symmetry broken system. We find that the optical bistability associated with the nonlinear response is tunable with the strength of the tilt, gap and chemical potential. This suggests the inputs for the development of future-generation optical devices.

description: AlScN and AlYN epitaxial layers bring two advantages for GaN based high-electron mobility transistors (HEMT): The high sheet charge carrier densities in the two-dimensional electron gas at the interface to GaN enables high drain currents and output powers, while the lattice parameter matchings to GaN allows for the growth of strain-free barriers promising for increased lifetimes of devices. For industrial applications, it is essential to grow these materials by metal-organic chemical vapour depostion (MOCVD), but the low vapour pressures of Sc and Y precursors limit the achievable growth rates and the high thermal budget leads to the degradation of the active interfaces. In this work, the growth rate is increased by employing novel Sc precursors and its impact on the structural and electrical properties of AlScN/GaN heterostructures is investigated in detail. AlScN/GaN HEMTs with the highest reported combination of output power and power added efficiency achieved for class-AB continuous wave operation at Ka-band frequencies on metal-polar GaN-based HEMTs are presented. Growth of AlYN and AlYN/GaN heterostructures by MOCVD is reported and discussed for the first time.

description: My dissertation critiques Western culture’s vertical command of “growing up” to adult completion (rational, heterosexual, married, wealthy, professionally successful) as a reductionist itinerary of human movement leading to subjective sedimentations. Rather, my project proposes ways of “moving rhizomatically” by which it advances a notion of a machinic identity that moves continuously, contingently, and waywardly along less vertical, less excruciating and more horizontal, life-affirmative trails. To this end, my thesis proposes a “rhizomatic semiosis” as extrapolated from the philosophy of Gilles Deleuze and Félix Guattari to put forward a notion of language and, by implication, subjectivity, as dynamic and metamorphic. Rather than trying to figure out who the child is or what it experiences consciously, my project wishes to embrace an elusiveness at the heart of subjectivity to argue for continued identity creation beyond the apparently confining parameters of adulthood. This dissertation, then, is about the need to re-examine our ways of growing beyond the lines of teleological progression. By turning to Deleuze’s child, an intangible one that “makes desperate attempts to carry out a performance that the psychoanalyst totally misconstrues” (A Thousand Plateaus 13), I wish to shift focus away from the hierarchical, binary, and ideal model of “growing up” and toward a notion of movement that makes way for plural identities in their becoming. This endeavour reveals itself in particular in the work of John Wray, Todd Field, Peter Cameron, Sara Prichard, Michael Cunningham, and Cormac McCarthy, whose work has received little or no attention at all—a lacuna in research that exists perhaps due to these artists’ innovative approach to a minor literature that promotes the notion of a machinic self and questions the dominant modes of Western culture’s literature for, around, and of children.

description: Women working in the Canadian Federal Public Service (CFPS) face complex issues and competing demands. However, despite challenges such as obtaining further education, managing home responsibilities, and dealing with workplace issues, some have also developed and managed successful careers. Problems highlighted within literature on career development for women relate to the nature of women’s lives with their many transitional points, in which personal and organizational factors inextricably intertwine. The purpose of this qualitative research study was to explore the career development and advancement of women towards and into entry executive level positions within the Canadian Federal Public Service (CFPS). Three research questions guided this inquiry: 1) How have personal factors influenced career development and advancement of women in the CFPS towards and into pre-executive and entry executive levels? 2) How have organizational factors influenced their career development and advancement? and 3) How have personal and organizational factors combined to influence their career development and advancement? This research was grounded in a social constructivist paradigm which guided the research both ontologically and epistemologically. Schwandt (1994) contends that “objective knowledge and truth is a result of perspective. Knowledge and truth are created, not discovered” (p. 125). The inquiry attempted, therefore, to understand women’s complex career development processes from a holistic perspective through their career life stories. Ten women at the pre-executive or entry executive level from various departments within the CFPS took part in the study. Data collection was carried out mainly through a series of three semi-structured interviews. The findings of the study describe how participants’ personal dispositions, formal education, and home lives (personal factors) influenced their career development and advancement. In addition, it was found that the organization’s culture of long hours, its support for learning, participants’ organizational networks, and superiors’ contributions (organizational factors) also influenced women’s careers. This study contributes to our understanding of women’s career development, thereby providing important insights for future research. The study may have implications for CFPS policymakers, career counsellors, universities responsible for educating future career counsellors, as well as for individual women themselves, and perhaps even men.

description: Service Oriented Virtual Organizations (SOVOs) business processes and services are subject to change to meet the internal and external requirements of the competitive, complex and rapidly changing environment they operate in. More practical and efficient ways of change management are needed to allow different partners to initiate changes to their business process and services in a faster and user-transparent manner. This thesis proposes a Change Management Framework for service oriented virtual organizations including a structural and a procedural framework. The structural framework categorizes changes in the SOVO into three layers of change; which include the value network layer, the collaborative process layer and the service providers’ layer, and identifies the impact of change on each layer. Furthermore, the structural framework identifies various triggers of changes which eventually lead to actions taken at the three layers. The change management procedural framework is derived from the ITIL V3, ECM and ECOLEAD best practices and recommendations, customized to fit the SOVO change requirements. It provides different components including the six layers for change processes, change control, change actors and related management processes. The change management procedural framework provides a sequence of steps and methods that the SOVO and its participated organizations can follow in initiating changes to their business processes or services. We design an implementation architecture and a prototype for building the change management console which enables the SOVO change management participants to initiate, assess, collaborate, monitor and authorize changes. The prototype is developed to realize and validate the change management process of change in the SOVO environment. We employ the various capabilities of the IBM Business Process Management (BPM) (including its recent Web 2.0 capabilities) to increase the collaboration between partners in the process of change. We demonstrate that the proposed solutions facilitate and enhance the process of change by effectively engaging the SOVO partners in the process of change.
First Steps toward Harmonized Human Biomonitoring in Europe: Demonstration Project to Perform Human Biomonitoring on a European Scale

description: Background: For Europe as a whole, data on internal exposure to environmental chemicals do not yet exist. Characterization of the internal individual chemical environment is expected to enhance understanding of the environmental threats to health.Objectives: We developed and applied a harmonized protocol to collect comparable human biomonitoring data all over Europe.Methods: In 17 European countries, we measured mercury in hair and cotinine, phthalate metabolites and cadmium in urine of 1844 children (5-11 years) and their mothers. Specimens were collected over a 5 month period in 2011-2012. We obtained information on personal characteristics, environment, and life style. We used the resulting database to compare concentrations of exposure biomarkers within Europe, to identify determinants of exposure, and to compare exposure biomarkers with health-based guidelines.Results: Biomarker concentrations showed a wide variability in the European population. However, levels in children and mothers were highly correlated. Most biomarker concentrations were below the health-based guidance values.Conclusions: We have taken the first steps to assess personal chemical exposures in Europe as a whole. Key success factors were the harmonised protocol development, intensive training and capacity building for field work, chemical analysis and communication, as well as stringent quality control programs for chemical and data analysis. Our project demonstrates the feasibility of a European-wide human biomonitoring framework to support the decision-making process of environmental measures to protect public health.Quelle: http://ehp.niehs.nih.gov

description: Deconstructing visual representations of the Self and Other in the online media of NGOs, this thesis is grounded in postdevelopment and postcolonial theories. Visual culture and emerging digital technologies are crucial to identity construction, and NGOs are a major purveyor of representations of those in the developing world. Evaluating image use by Canadian based NGOs, this thesis unites theoretical concepts of visual representation with concrete photographic depictions and structured content analysis to investigate multiple and changing development discourses. Considerable literature has focused on the notion of the Self and Other dichotomy especially as it relates to international relations. Positioned in an era of polycentric global governance, NGOs are professionalized groups whose power is often obscured by charitable discourses. Despite the humanitarian and altruistic aims of the NGOs selected for the study, data demonstrates the implications of their image use for development discourse and practices.

description: The Tibbitt-to-Contwoyto Winter Ice Road (TCWR) is the sole overland route servicing diamond mines north of Yellowknife, Northwest Territories (NWT), Canada. The road is 568 km long, 85% of which extends over frozen lakes. As such, its operational season is highly dependent upon the length of the winter season. This was exemplified in 2006, when an El Niño event caused an unusually short ice road season and resulted in a costly reduction of shipments to the mines. For future use and development of the TCWR, a comprehensive understanding of past regional climate variability is required. This study is an integral component of a larger-scale study designed to develop a comprehensive database of high-resolution paleoclimate data for the NWT, using a variety of proxies. As part of the larger study, freeze cores were taken from numerous lakes along the TCWR and sliced at 1-mm intervals using a custom-designed sledge microtome. Bulk 13C and 15N isotope analysis was completed at preliminary 1-cm intervals through the cores of two lakes on opposite sides of the tree line. Results from this analysis show clear trends with distinct transitions in both cores, whose closely-matched timing suggests regional-scale climate events. These results indicate that the Early Holocene was warm and dry, with a sudden shift to wetter conditions around 7200-6900 cal yr BP. Another shift to cooler conditions occurred at 4000 cal yr BP, and a final transition to even cooler temperatures occurred around 755-715 cal yr BP, coinciding with the Little Ice Age. Additionally, a modern lake survey was completed using surface sediments of numerous lakes throughout the Arctic and Subarctic. This survey verifies the strong influence of boreal forest vs. tundra conditions in affecting various environmental properties within lakes, including carbon and nitrogen isotopes. Lastly, time-series analysis was completed on two sections of Danny’s Lake core at high resolution (up to 2 mm), in order to determine short-term climate cycles. These results highlight specific climate frequencies which may be related to the Pacific Decadal Oscillation. These results offer insight to short-term climate phenomena in the Northwest Territories which will allow future climate modellers to make more accurate predictions of future climate and its impact on the ice road.

Occurrence —Cajon Pass, San Bernardino National Forest, San Bernardino County, California. Exact locality data are on file at the USFS and WSC. Subdivision Tcv5, Cajon Valley Formation (Woodburne and Golz 1972, Morton and Miller2003); middle Miocene, late Hemingfordian–middle Barstovian NALMA; Tcv5 (unit 5) spans approximately 16.5–14 Ma (Liu 1990).
Description —Several teeth from a small brachydont horse were collected by WSC personnel from the Cajon Valley Formation, in subdivision Tcv5. These teeth, based upon their small size, lack of cement, and absence of a well-developed crochet, are best referred to the genus Archaeohippus (Pagnac 2005) (Fig. 2). WSC 8826, the only adult molar in the WSC sample, lacks a crochet completely and so is referred to Ar. mourningi (Pagnac 2005). Because of size and brachydont condition, all other referred specimens in the WSC sample are also referred to Ar. mourningi. Pagnac and Reynolds (2010) also described Ar. mourningi material from the Cajon Valley Formation, including a juvenile skull from Tcv5. Merriam (1913) originally named this species as Parahippus (?) mourningi, which was then transferred to the genus Archaeohippus by Osborn (1918).

description: The heterogeneity of biomass characteristics is a major challenge for all thermochemical conversion processes. This work describes the development from the idea to a working prototype for a system with which online fuel characteristics can be identified. The idea as well as the scientific work are based on the following hypothesis: If warm air flows through a solid bed of biogenic fuels, it interacts with the solid bed during the flow. The physical processes occurring in this process measurably change the properties of the air. Based on these changes, it is possible to draw conclusions about relevant fuel prop erties (water content, bulk density) and the type of fuel. In a first step, a test rig was developed with which defined fuel samples can be dried and the changes in temperature, water content and pressure drop can be analyzed. First, a screening test series with a wide range of feedstocks (wood chips, forest residues, wood pellets, saw dust, corn cobs, biochar from digestate and aluminum oxide spheres) was conducted to create an initial data basis. Through this series of tests, the general feasi bility of the idea could be demonstrated. The data from the test series were used to develop an evaluation logic by combining data-based and analytical approaches. Based on this preliminary work, a prototype was developed and connected directly to an auto matically fed grate furnace in the Fraunhofer UMSICHT technical center. After commis sioning of the prototype, test series were carried out with wood chips, forest residues, saw dust and wood pellets. These tests created the data basis for training and evaluating a machine learning algorithm. For evaluation the furnace was alternately fed with wood chips, forest residues and wood pellets. Regarding the accuracy, it could be shown that the identification of the feedstock succeeds with a probability of about 90% for wood chips and forest residues and 100% for pellets. The determination of the water content and the bulk density showed that the orders of magnitude were correctly determined. The deviation in the water content was on average between 1.7% and 4.1% in absolute terms. The precision in the determination of the bulk density lies with a relative error of 10.42% for wood chips, 15.41% for forest residues and 5.98% for wood pellets. In the end, the hypothesis was confirmed, and the basic idea was turned into a working proto type.

description: Das Bürstspanen mit gebundenem Schleifmittel ist ein industriell vielfach eingesetztes Fertigungsverfahren zur Nachbearbeitung von technischen Oberflächen. Die Auslegung der dazugehörigen Bürstprozesse erfolgt jedoch in den meisten Anwendungsfällen auf Grundlage von zeitaufwändigen Vorversuchen und Erfahrungswerten. Um eine wissensbasierte Prozessauslegung zu ermöglichen, wird in dieser Arbeit ein besseres Verständnis zur Technologie des Bürstspanens mit gebundenem Schleifmittel von technischen Oberflächen aufgebaut. Dazu werden auf Grundlage von experimentellen Untersuchungen empirische Prozessmodelle erstellt, die Vorhersagen zur Produktivität von Bürstprozessen an Werkstücken mit einfacher Geometrie bereitstellen. Zusätzlich wird ein kinetisches Prozessmodell entwickelt, das an Werkstücken mit variierenden geometrischen Ausprägungen zur Berechnung der wirkenden Bearbeitungskräfte und der Bewegung der Schleiffilamente des Bürstwerkzeuges eingesetzt werden kann. Die kombinierte Anwendung der Prozessmodelle bietet schließlich die Möglichkeit Vorhersagen zur Wirtschaftlichkeit des Bürstprozesses für komplexe Werkstückgeometrien zu treffen, ohne zusätzliche experimentelle Untersuchungen durchzuführen.
Experiencing a re-entry: second-career academics in business schools in Malaysia
Creators: name: Ong, Liap Teck
Publisher: name: Swinburne

description: This research studied the experience of second-career academics in Malaysian business schools. A combination of interpretive research paradigm and narrative inquiry has been adopted for this study. The research revealed that second-career academics are motivated by self-efficacy, inspired by a sense of calling, delighted by accordance, but disenchanted by discordance, and alienated by grievance. Theoretically, these results suggest the transferability of self-efficacy in career transition from industry to academia. The study suggests that universities need to review the career appraisal process and a re-examination of academic performance management systems. It also calls for an improved orientation process for second-career academics.

description: Cette étude explore l’étendue de la pratique de natation parmi les Noirs au Canada à l’aide de sources d’archives primaires et secondaires. Ceci vise à vérifier si la « théorie » de l’incapacité des Noirs à nager que l’on retrouve aux États-Unis fut aussi véhiculée au Canada. La période d’étude de notre recherche s’étend des années 1900 à l’année 1970, période durant laquelle la natation s’est développée. Ce travail avait également comme but d’explorer les relations raciales en natation au Canada en analysant l’expérience parmi les Noirs dans ce sport. Pour ce faire, la pratique de la natation est examinée dans le cadre de la critical race theory. Durant cette analyse, deux thèmes en lien avec la théorie et la littérature sont ressortis de l’information recueillie des archives. Ils concernent le privilège blanc en natation et le lien entre la natation et la Condition Blanche (Whiteness) de tradition britannique impériale.

description: Studies of birds have made a fundamental contribution to elucidating sperm competition processes, experimentally demonstrating the role of individual mechanisms in competitive fertilization. However, the relative importance of these mechanisms and the way in which they interact under natural conditions remain largely unexplored. Here, we conduct a detailed behavioural study of freely mating replicate groups of red junglefowl, Gallus gallus, to predict the probability that competing males fertilize individual eggs over the course of 10-day trials. Remating frequently with a female and mating last increased a male's probability of fertilization, but only for eggs ovulated in the last days of a trial. Conversely, older males, and those mating with more polyandrous females, had consistently lower fertilization success. Similarly, resistance to a male's mating attempts, particularly by younger females, reduced fertilization probability. After considering these factors, male social status, partner relatedness and the estimated state of a male extragonadal sperm reserves did not predict sperm competition outcomes. These results shed new light on sperm competition dynamics in taxa such as birds, with prolonged female sperm storage and staggered fertilizations.This article is part of the theme issue ‘Fifty years of sperm competition’.
