description: Parvorder Iurida Soleglad & Fet, new parvorder   Composition. This parvorder, established here, includes three superfamilies (Chactoidea, Iuroidea, and Scorpionoidea) and 10 families. It corresponds to orthobothriotaxy “ Type C” (Vachon, 1974; Soleglad & Fet, 2001).
 Distribution. All continents except Antarctica.
 Biogeographic history. Our phylogenetic analysis demonstrates the relationship between three superfamilies of this parvorder as (Iuroidea, (Scorpionoidea, Chactoidea)). Since already the oldest of superfamilies, Iuroidea, has a disjunct modern distribution between the New World and the Mediterranean, representatives of the parvorder Iurida should clearly have been present in the times of Pangea, which marks the possible upper age (Triassic) of the youngest node in the phylogeny of extant scorpions at the parvorder level (split of parvorder Iurida, the most derived of four scorpion parvorders). The oldest known fossils of Iurida are Cretaceous (families Protoischnuridae and Palaeoeuscorpiidae). All three superfamilies of Iurida exhibit worldwide distribution, variously disjunct at the level of families, tribes, and sometimes even genera.
 Diagnosis. Scorpions in the parvorder Iurida can be distinguished by the following characters: Synapomorphies. Orthobothriotaxy type C; ventral surface of cheliceral fixed finger without denticles; sternum type 2; hemispermatophore is lamelliform; pedipalp patella with “5-carinae” configuration; three lateral eyes present. Important Symplesiomorphies. None.
 Discussion. The phylogeny of the parvorder Iurida, as established here, supports the topology (Iuroidea, (Scorpionoidea, Chactoidea)). This conflicts with the interpretation of Stockwell (1989) who included Iuridae (=current Iuroidea) in his Vaejovoidea.
Characters used to define the superfamilies of parvorder Iurida are cheliceral dentition, leg pedal spurs, leg tarsus armature, and the paraxial organ.

description: This thesis presents an introduction to the design and simulation of a novel class of integrated photonic phased array switch elements. The main objective is to use nano-electromechanical (NEMS) based phase shifters of cascaded under-etched slot nanowires that are compact in size and require a small amount of power to operate them. The structure of the switch elements is organized such that it brings the phase shifting elements to the exterior sides of the photonic circuits. The transition slot couplers, used to interconnect the phase shifters, are designed to enable biasing one of the silicon beams of each phase shifter from an electrode located at the side of the phase shifter. The other silicon beam of each phase shifter is biased through the rest of the silicon structure of the switch element, which is taken as a ground. Phased array switch elements ranging from 2×2 up to 8×8 multiple-inputs/multiple-outputs (MIMO) are conveniently designed within reasonable footprints native to the current fabrication technologies. Chapter one presents the general layout of the various designs of the switch elements and demonstrates their novel features. This demonstration will show how waveguide disturbances in the interconnecting network from conventional switch elements can be avoided by adopting an innovative design. Some possible applications for the designed switch elements of different sizes and topologies are indicated throughout the chapter. Chapter two presents the design of the multimode interference (MMI) couplers used in the switch elements as splitters, combiners and waveguide crossovers. Simulation data and design methodologies for the multimode couplers of interest are detailed in this chapter. Chapter three presents the design and analysis of the NEMS-operated phase shifters. Both simulations and numerical analysis are utilized in the design of a 0º-180º capable NEMS-operated phase shifter. Additionally, the response of some of the designed photonic phased array switch elements is demonstrated in this chapter. An executive summary and conclusions sections are also included in the thesis.

Referred specimen —SC2013.38.7, incomplete anterior tooth.
Remarks —This specimen differs from Nebrius sp. cf. Neb. thielensi (see above) in having only a single pair of large lateral cusplets, and the labial crown foot is distinctively bifid but not drawn out into an elongate basal protuberance. SC2013.38.7 is similar to the anterior teeth of Cretaceous Plicatoscyllium Case and Cappetta, 1997, but there is no indication of labial crown ornamentation. The single pair of lateral cusplets also distinguishes SC2013.38.7 from the various early Paleogene species of Ginglymostoma (Noubhani and Cappetta 1997). In terms of gross morphology, SC2013.38.7 is similar to Protoginglymostoma ypresiensis (Casier, 1946) from the early to middle Eocene of Belgium and Morocco (Casier 1946, Herman 1977, Tabuce et al. 2005), but the poor condition of the only available tooth makes a more precise identification difficult.

description: Vitamin D regulation is associated with several human disorders and contributes to various cellular mechanisms. Calcitriol (commercially available as Rocaltrol), an active Vitamin D metabolite, is known as a neuro-protective and anti-cancer drug but most importantly helps maintaining the calcium homeostasis inside the human body. The effectiveness of calcitriol to perform as an effective therapeutic agent is counteracted by its calcemic effects. In order to obtain better therapeutic results, synthetic calcitriol analogs without these calcemic effects have been recently developed but they are not yet cost-effective and their production is time-consuming. In order to determine the best active form of calcitriol that could provide higher chemotherapeutic activity without these calcemic effects, calcitriol mode of action was studied using yeast as a model system. In order to achieve this, we analyzed the calcitriol effects on yeast cellular growth based on calcium intake levels. In this work, we also assessed yeast strains with gene deletions of selected calcium transporter genes to understand the calcitriol metabolism. For the aim of understanding hypercalcemic effects of calcitriol, we developed a hypothesis based on calcitriol interactions with oxygen. Interestingly, use of an anaerobic model validated the oxygen interactions with calcitriol that might possibly cause calcemic effects on patients. Anaerobically grown yeast treated with calcitriol showed significantly less intracellular calcium levels when imaged under indo-1 calcium binding fluorescence dye as compared to calcitriol treated yeast grown under aerobic conditions. Finally, we predict that calcitriol might control free radical generation within the yeast system based on experiments with AAPH and UV- irradiation.

description: We present images from a space-VLBI survey using the facilities of the VLBI Space Observatory Programme (VSOP), drawing our sample from the well-studied Pearson-Readhead survey of extragalactic radio sources. Our survey has taken advantage of long space-VLBI baselines and large arrays of ground antennas, such as the Very Long Baseline Array and European VLBI Network, to obtain high-resolution images of 27 active galactic nuclei and to measure the core brightness temperatures of these sources more accurately than is possible from the ground. A detailed analysis of the source properties is given in accompanying papers. We have also performed an extensive series of simulations to investigate the errors in VSOP images caused by the relatively large holes in the (u,v)-plane when sources are observed near the orbit normal direction. We find that while the nominal dynamic range (defined as the ratio of map peak to off-source error) often exceeds 1000: 1, the true dynamic range (map peak to on-source error) is only about 30: 1 for relatively complex core-jet sources. For sources dominated by a strong point source, this value rises to approximately 100: 1. We find the true dynamic range to be a relatively weak function of the difference in position angle (ppA.) between the jet ppA. and u-v coverage major axis ppA. For regions with low signal-to-noise ratios, typically located down the jet away from the core, large errors can occur, causing spurious features in VSOP images that should be interpreted with caution.

description: In dieser Arbeit wurde der Einfluss von Störungen unterschiedlicher Art auf die robotergestützte Wirbelstromprüfung untersucht. Es wurde gezeigt, dass die Störungen sich in unvermeidbare und vermeidbare Kategorien unterteilen lassen. Die vermeidbaren Störungen, wie Abhebe- und Kippeffekt, können mit strukturierte Modellierung und optimale Befestigung der Sensoren minimiert werden. Mit Daten unterschiedlicher Beschleunigungssensoren lässt sich diese Hypothese nachweisen. Durch eine Vibrationsanalyse des Roboters und den Vergleich zwischen den Vibrationsdaten mit den Wirbelstromprüfdaten wurde festgestellt, dass die meisten Vibrationen unvermeidbar sind. Diese Vibrationen entstehen durch die vorprogrammierte Bewegung des Wirbelstromprüfkopfes und des internen Bremsvorgangs des Roboters. Die Amplitude dieser Schwingung ist jedoch am größten bei der Basisachse des Roboters. Mit dem Abstand zu der Basisachse nimmt diese Amplitude ab und beeinflusst die Daten der Wirbelstromprüfung nicht. Neben Vibrationen wurden auch die Temperaturänderungen während der Messung erfasst. Dadurch wurde festgestellt, dass sich die Temperatur in einer Industrieumgebung oder in einem Labor kaum ändert. Es wurde eine ordentliche Störanalyse mit dem Roboter durchgeführt und dabei die kritischen Störungen sowie ihre Ursachen identifiziert. Für Zukünftige Analysen können weitere Störungen berücksichtigt werden. Es könnte z.B. eine reine Geschwindigkeitsbetrachtung vorgenommen werden mit IMU-Sensoren oder es kann an EMV-Störungen gearbeitet werden. Eine weitere Möglichkeit besteht im Testen des Verhaltens der größten Vibrationspeaks in verschiedenen Umgebungen. Liegen genügend Daten des Roboters vor, ist eine umfassende Zustandsbewertung oder ein Condition-Monitoring eher möglich. Die Ergebnisse dieser Arbeit können für weitere Projekten des Fraunhofer IZFP verwendet werden.
Phosphatidylcholine Metabolism and ACAT Affect the Trafficking of LDL-derived Free Cholesterol in Cholesterol-loaded CHO Cells

description: In vitro studies have shown that the major membrane phospholipid phosphatidylcholine (PC) can positively influence the incorporation of cholesterol in lipid membranes. The influence of PC on the cellular trafficking of LDL-derived free cholesterol was investigated. Sterol regulatory-defective (SRD)-4 cells are Chinese hamster ovary (CHO)-derived fibroblasts that display vastly elevated rates for the synthesis and catabolism of PC. SRD-4 cells harbor two known gene mutations: a mutation in the functional allele for SCAP, resulting in defective feedback suppression of cholesterol biosynthesis; and a loss-of-function mutation in the functional allele for acyl-CoA:cholesterol acyl transferase (ACAT), an endoplasmic reticulum (ER)-localized enzyme that esterifies free cholesterol. Incubation of SRD-4 cells with 50 µg/ml low density lipoprotein (LDL) for 18 h resulted in lysosomal accumulation of free cholesterol as revealed by filipin staining. This accumulation was not evident following LDL treatment of parental CHO7 cells, and was blunted in SRD-2 cells that express a constitutively-active form of SREBP-2 and overproduce cholesterol but have functional ACAT activity. Treatment of SRD-2 cells with LDL in the presence of an ACAT inhibitor 58-035 resulted in robust lysosomal cholesterol accumulation that was reversible upon drug washout, supporting that cholesterol trafficking in cholesterol-loaded cells is dependent on ACAT activity and, more specifically, ER free cholesterol levels. Lysosomal accumulation of LDL-derived cholesterol was prevented in SRD-4 cells supplemented with lyso-PC (50 µM), a substrate for PC synthesis through the reacylation pathway, and also in cells treated with bromoenol lactone (BEL), an inhibitor of phospholipase A2 implicated in bulk PC turnover. In a counter study, lysosomal LDL-derived cholesterol accumulation was induced in parental CHO-7 cells using R-propranolol, which inhibits the conversion of phosphatidic acid to diacylglycerol (DAG), a substrate in the CDP-choline pathway. This blockage was also relieved through co-treatment with lyso-PC. These studies support that PC to free cholesterol ratios in downstream organellar membranes can influence cholesterol trafficking out of lysosomal compartments in cholesterol-loaded cells.

description: In this dissertation, we introduce a novel text representation method mainly used for text classification purpose. The presented representation method is initially based on a variety of closeness relationships between pairs of words in text passages within the entire corpus. This representation is then used as the basis for our multi-level lightweight ontological representation method (TOR-FUSE), in which documents are represented based on their contexts and the goal of the learning task. The method is unlike the traditional representation methods, in which all the documents are represented solely based on the constituent words of the documents, and are totally isolated from the goal that they are represented for. We believe choosing the correct granularity of representation features is an important aspect of text classification. Interpreting data in a more general dimensional space, with fewer dimensions, can convey more discriminative knowledge and decrease the level of learning perplexity. The multi-level model allows data interpretation in a more conceptual space, rather than only containing scattered words occurring in texts. It aims to perform the extraction of the knowledge tailored for the classification task by automatic creation of a lightweight ontological hierarchy of representations. In the last step, we will train a tailored ensemble learner over a stack of representations at different conceptual granularities. The final result is a mapping and a weighting of the targeted concept of the original learning task, over a stack of representations and granular conceptual elements of its different levels (hierarchical mapping instead of linear mapping over a vector). Finally the entire algorithm is applied to a variety of general text classification tasks, and the performance is evaluated in comparison with well-known algorithms.

description: Background Respiratory health conditions appear to be more common among First Nations people versus non-First Nations people in Canada. However, the prevalence of chronic obstructive pulmonary disease (COPD) and its associated risk factors in First Nations communities are unknown. This project aims to estimate the prevalence of COPD in several First Nations communities in British Columbia, Canada and to characterize respiratory symptoms, COPD risk factors, and healthcare utilization. Methods This project is approved by both the University of British Columbia and Carrier Sekani Family Services Research Ethics Boards. We will randomly sample 220 adults, 30 years and older, from 11 participating First Nations. Each participant will complete pre- and post-bronchodilator spirometry tests and the adapted American Thoracic Society Epidemiological Questionnaire with items about smoking history, respiratory symptoms, co-morbidities, and exposures, in order to identify the presence of COPD and its associated individual, occupational, and community risk factors. Homes will be assessed for air quality measures including particulate matter, carbon monoxide and carbon dioxide, and humidity. Health care utilization will be abstracted from the electronic medical record. Discussion This is the first project in Canada to estimate the prevalence of COPD in First Nations communities using a random-sampling approach to recruitment. Additionally, although this study will collect detailed information on smoking history, we will also characterize past and current risk factors beyond cigarette smoking. Finally, our methodology ensures that the benefits to the communities are realized during the study period. Individual results will be shared with individuals and health providers to facilitate care. Air quality results will be sent to each Nation’s governing council to facilitate remediation where necessary. Trial registration The study has been retrospectively registered at clinicaltrials.gov ( NCT04105088 ).

description: In this letter, we present a study of orthogonal polarization modes in the radio emission of PSR B1133+16, conducted within the frame of simultaneous, multi-frequency, single-pulse observations. Simultaneously observing at two frequencies (1.41 GHz and 4.85 GHz) provides the means to study the bandwidth of polarization features such as the polarization position angle. We find two main results. First, that there is a high degree of correlation between the polarization modes at the two frequencies. Secondly, the modes occur more equally and the fractional linear polarization decreases towards higher frequencies. We discuss this frequency evolution and propose propagation effects in the pulsar magnetosphere as its origin.

description: The immense data demand for upcoming wireless communication standards, for example 5G or the even more advanced 6G, requires new concepts to handle the respective network throughput. Nowadays, conventional systems necessitate complex architectures with a high number of components to operate at different communication standards. This thesis analyzes a system that reduces the number of the currently required components to a one-chip solution, functioning as a digital transmitter geared towards software defined radio systems in 5G. Here, a new concept is presented that is able to synthesize outputs, which are composed of various signals, concurrently modulated on the same carrier frequency. The combination of a core Digital-to-Analog Converter (DAC) circuit cointegrated with a power amplifier, named Riemann Pump, improves the signal-to-noise ratio of conventional DACs, while also improving the output power performance. Therefore, the Riemann Pump results in a signal generator that is capable of providing several watts of output power at radio frequencies to a 50 Ω load environment. With the Riemann Pump it is possible to synthesize signals that find usage in the new radio standard in 5G communication.

Remarks —One hundred thirteen Dry Branch Formation teeth are similar to those of extant Rhizoprionodon, and to Eocene Rhiz. ganntourensis, in particular. The distal heel of Rhizoprionodon, including Rhiz. ganntourensis, is generally cuspidate (Arambourg 1952, Herman et al. 1991, Case et al. 1996, Noubhani and Cappetta 1997, Mustafa et al. 2005), but our specimens lack enameloid and this feature is not preserved. However, we examined a tooth of Rhiz. sp. cf. Rhiz. ganntourensis that was recovered by Zullo and Kite (1985) from the Griffins Landing Sand (see Appendix 1), and found that it is very similar to the material listed above. The well preserved Griffins Landing Sand tooth exhibits a cuspidate distal heel, but the translucent enameloid allows us to view the unifromly convex dentine core of the heel, as can be seen on the specimens in our sample.

description: Gene regulatory networks are dynamic and continuously remodelled in response to internal and external stimuli. To understand how these networks alter cellular phenotype in response towards specific challenges, my first project sought to develop a methodology to explore how the strength of genetic interactions changes according to environmental context. Defined as sensitivity-based epistasis, the results obtained using this methodology were compared to those generated under the conventional fitness-based approach. By integrating this information with gene expression profiles and physical interaction datasets, we demonstrate that sensitivity-based epistasis specifically highlights genetic interactions with a dynamic component. Having investigated how an external stimulus regulates network dynamics, we next sought to understand of how genome positioning impacts transcription kinetics. This feat was accomplished by cloning two gene-reporter constructs, representing contrasting promoter architectures, across 128 loci along chromosome III in S.Cerevisiae. By comparing expression and noise measurements for promoters with “covered” and “open” chromatin structures against a stochastic model for eukaryotic gene expression, we demonstrate that while promoter structure regulates burst frequency (the rate of promoter activation), positional effects in turn appear to primarily modulate burst size (the number of mRNA produced per gene activation event). By integrating these datasets with information describing global chromatin structure, we suggest that the acetylation state of chromatin regulates burst size across the genome. Interestingly, this hypothesis is further supported by nicotinamide-mediated inhibition of Sir2 which would appear to modulate burst size globally across the genome.

description: Im Rahmen der vorliegenden Masterarbeit wurde ein Transportmodell für Power-to-XProdukte entwickelt, um die Transportkosten für Wasserstoff, Ammoniak und Methanol zu berechnen. Die Herstellung der berücksichtigten Produkte erfolgt zurzeit aus fossilen Energieträgern. Um die angestrebte Klimaneutralität zu erreichen, ist eine Defossilisierung der Herstellungsprozesse notwendig. Mit der Umstellung der Herstellungsprozesse können die Produkte künftig in weiteren Regionen mittels regenerativer Energien hergestellt werden. Deshalb sind für die Verbraucher im industriellen Bereich, die sich verändernden Transportkosten in Abhängigkeit von Produktionsmenge und Entfernung von großem Interesse. Für die Ermittlung der Transportkosten wurde in im ersten Schritt eine techno-ökonomische Analyse durchgeführt. Auf Basis der Erkenntnisse aus der Analyse wurde anschließend das Transportmodell entwickelt, das sich in die Bereiche Konfektionierung, Speicherung, Transport und Entpackung unterteilt. Für die automatisierte Berechnungen der Transportkosten wurde ein Computerprogramm in Python geschrieben. Durch Interaktion des Anwenders mit dem Programm können die Standorte frei ausgewählt werden und für das Projekt individuelle Produktionsmengen in Form von jährlichen Zeitreihen oder Jahresproduktionen verwendet werden. Mit diesen Informationen und den hinterlegten Annahmen werden die Transportkosten nach der Annuitätenmethode berechnet. Die Überprüfung des Programms auf seine Funktionalität wurde mittels einer Beispielrechnung für den Transport von Australien nach Deutschland per Schiff durchgeführt. Aus der Berechnung ergeben sich heutige Transportkosten für flüssigen Wasserstoff von 17,9 €/kgH2 , Liquid Organic Hydrogen Carrier LOHC von 3,92 €/kgH2 , Ammoniak von 92,72 €/tAmmoniak und Methanol von 123,23 €/tMethanol. Die Validierung der Ergebnisse wurde mit Literaturwerten durchgeführt, die ebenfalls die Kosten für den Transport von Australien nach Deutschland per Schiff berechnet haben. Bei dem Vergleich zeigte sich, dass die Kosten von flüssigem Wasserstoff, LOHC und Ammoniak oberhalb der Literaturwerte liegen. Nur Methanol liegt im oberen Bereich der Literaturwerte. Die Abweichungen sind darauf zurückzuführen, dass in der Literatur mit kleineren spezifischen Kosten der Schiffe gerechnet wird. Weiterhin sorgen die geringen Produktionsmengen von Methanol und Ammoniak für eine geringe Auslastung der Schiffe, wodurch höhere Transportkosten entstehen.

Ten years ago, Garrison, Anderson, and Archer (2000) published an article describing the Community of Inquiry (CoI) framework which provided an outline of three core elements that were able to describe and measure a collaborative and positive educational experience in an online learning environment, namely teaching presence (design, facilitation, and direct instruction), social presence (the ability of learners to project themselves socially and emotionally), and cognitive presence (the extent to which learners are able to construct and confirm meaning through sustained reflection and discourse). This dissertation extends the body of research surrounding the CoI framework and also the literature on developing critical thinking in online environments by examining and exploring the extent to which teaching and social presence contribute to cognitive presence. The researcher was able to do this by offering 189 learners enrolled in 10 research methods courses and educational research courses an opportunity to use an innovative online resource (Research Design Learning Resource – RDLR) to assist them in learning about educational research and developing research proposals. By exploring how participants used this resource the researcher was able to gain insight into what factors contributed to a successful online learning experience and fostered cognitive presence. Quantitative and qualitative research approaches (mixed methods) were used in this study. The quantitative results indicated that both social and teaching presence had a strong positive relationship with cognitive presence and that learners generally perceived to have a positive learning experience using the RDLR. The qualitative findings helped elaborate the significant quantitative results and were organised into the following themes: making connections, multiple perspectives, resource design, being a self-directed learner, learning strategies, learning preferences, and barriers to cognitive presence. Future directions for critical thinking in online environments are discussed.

description: Multidrug resistance phosphoglycoprotein (MDR1/P-gp) and breast cancer resistance protein (BCRP) were first isolated in chemoresistant cancer cells and have since been found in a variety of normal tissue, including the placenta. The potential function of MDR1/P-gp and BCRP in the human placenta is to protect the fetus from maternally circulating endogenous steroids and hormones, therapeutic drugs and toxins. The objective of this study was to examine the role of maternal steroids in the regulation of MDR1/P-gp and BCRP in the human placenta. Trophoblast cells were isolated from term placenta tissues and immunohistochemistry, western blot analysis and transport studies were used to determine the effect of maternal steroids on MDR1/P-gp and BCRP regulation. Maternal steroids, present at high concentrations in maternal serum, did not have an effect on BCRP in human syncytiotrophoblast. Estrogen and progesterone did not alter MDR1/P-gp levels in human syncytiotrophoblast, but cortisol significantly decreased MDR1/P-gp levels.

description: This study presents an analysis of rhetorical devices in an Indian Supreme Courtjudgment, examining how devices like ethos, pathos, and logos structure judiciallanguage to communicate authority and interpret constitutional principles. Theanalysis reveals the crucial role of rhetorical strategies in shaping legal reasoningand public perception of judicial authority.In addition to Supreme Court judgment analysis, this research intends to explorevarious other legal documents in future works. These include:Police First Information Reports (FIRs): Essential for initiating criminal investigationsand documenting the details of alleged offenses.Judicial Opinions and Orders: Providing insights into the decision-making processesof various courts.Legal Briefs: Presenting arguments and legal principles to the court, significant forunderstanding advocacy in litigation.Contracts: Analyzing the linguistic structures that define obligations and rightsbetween parties.Legislation and Statutes: Examining the rhetorical frameworks that shape theinterpretation and implementation of laws.By establishing a framework for rhetorical analysis in Supreme Court judgments, thisstudy lays a foundation for examining these and other legal texts in future articlesand forthcoming books.

description: Research shows that there is a gap between interest and experience in the area of sexuality for individuals with autism. Also, although these individuals have unique learning requirements pertaining to their sexuality, there is no consensus on the provision and content of such education. Using a socially inclusive theoretical lens founded on existing models of disability and competence, this bilingual study (a) developed a conceptual framework of sexuality education, as understood by adolescents living in Ontario with a diagnosis of high-functioning autism and their caregivers; (b) used extant texts to support the conceptualization provided by youth and caregivers; and (c) identified personal strengths and barriers, as well as societal supports and barriers that impact sexuality education for these youth. Using a qualitative orientation, this study employed in-depth interviews, surveys, and a literature review to better understand the topic under investigation. Twenty participants from 8 families took part in these interviews, including 9 adolescents and 11 caregivers. Survey and extant textual-analysis data were used to support the findings. Sexuality education content was conceptualized as a combination of facts and sociosexual norms, with emphasis on outcomes. Additionally, safety and pleasure were identified as important content areas, including the historically absent aspect of shared enjoyment. Some content areas were part of a greater discourse of normalization. Sexuality education was seen as a combination of formal and informal activities that are developmentally appropriate, proactive, and take place across various settings and groupings. Caregivers were cited as the primary providers of informal education, whereas schools and other community partners were seen as formal providers of education. Various supports and barriers were identified, some of which were viewed as both. Themes related to media and technology pervaded all findings. This study provides further emic and etic understanding of the subject with implications for practice, policy, and theory.

description: Leadership is important to quality improvement initiatives in healthcare. However, few studies have evaluated leadership interventions to enhance nurses’ use of guideline recommendations in the field of knowledge translation. Purpose: To develop and evaluate an intervention designed to operationalize a leadership strategy composed of relations, change, and task-orientated leadership behaviours, and to examine its influence on nurses’ use of guideline recommendations in home-care nursing. Design: Sequential mixed methods pilot study with post-only cluster randomized controlled trial. Methods Phase I: Intervention Development 1. A participatory approach was used at a community healthcare organization with 23 units across the province of Ontario, Canada. The guideline selected was developed by the Registered Nurses’ Association of Ontario for the assessment and management of foot ulcers for people with diabetes. 2. Integrative literature review, qualitative interviews, and baseline chart audits were conducted. 3. Four units were randomized to control or experimental groups. 4. Clinical and management leadership teams participated in a 12-week intervention consisting of printed materials, interactive workshop, and teleconferences. Participants received summarized chart audit data, identified priority indicators for change, and created a team leadership action plan to address barriers and influence guideline use. Phase II: Evaluation 5. Chart audits compared differences in nursing process and patient outcomes. Primary outcome: eight-item nursing assessment score. 6. Qualitative interviews evaluated the intervention and leadership behaviours. Results: No significant difference was found in the primary outcome. A significant difference was observed in nurses’ documentation of five priority indicators chosen by the experimental groups (p=.02). Gaps in care included: 53%, 76%, and 94% of patients not assessed for ulcer depth, foot circulation, or neuropathy (respectively); 75% and 93% did not receive wound debridement or hydrogel dressings. Receiving data to identify priority indicators for change and developing a leadership action plan were reported as useful to guideline implementation. The experimental group described using more relations-oriented leadership behaviours conducting audit and feedback, and sending reminders. Conclusion: Findings from this pilot study suggest that leadership is a team process involving relations, change, and task-oriented behaviours enacted by managers and clinical leaders. A leadership model is proposed as a beginning taxonomy to inform future leadership intervention studies.

description: In this thesis a theoretical model of laser nonlinearity is analysed and the intermodulation noise is calculated. The large-signal-model of the laser rate equations is used in the analysis. An output-to-input approach is used to obtain a general system equation for the laser and then Volterra series expansion is applied to the system equation to obtain system transfer functions. First, the nth-order Volterra transfer functions, $G\sb{n}$($w\sb1$, ...,$w\sb{n}$), from output to input are calculated. Then, based on harmonic balance the forward Volterra transfer functions, $F\sb{n}$($w\sb1$, ...,$w\sb{n}$), are calculated from $G\sb{n}$($w\sb1$, ...,$w\sb{n}$), and these $F\sb{n}$($w\sb1$, ...,$w\sb{n}$), are used to model the frequency dependent form input-to-output nonlinearities of the laser. The theoretical models for second harmonic (2HD), third harmonic (3HD) and third-order intermodulation (IMD) distortions are expressed in terms of signal frequency, optical modulation depth and laser parameters. Using the Mircea-Sinnreich equations, intermodulation spectra are computed. Harmonic distortions and third-order intermodulation distortion for various carrier (C) levels have been computed and variations of 2HD/C, 3HD/C and IMD/C with frequency and D.C. bias are shown graphically. This system analysis are compared with previously published results and a good agreement is found. (Abstract shortened by UMI.)

(FIG. 7F–I)
Referred specimens —SC96.97.52, 22 medial tooth fragments; SC96.97.53, lateral tooth; SC 2001.1.3, 118 partial medial teeth; SC 2001.1.4, three lateral teeth; SC 2001.1.5, 10 lateral teeth; SC 2001.1.6, lateral tooth; SC 2001.1.7, lateral tooth; SC2013.38.84, lower medial tooth; SC2013.38.85, upper medial tooth; SC2013.38.86, upper medial tooth; SC2013.38.87, upper medial tooth; SC2013.38.88, incomplete upper medial tooth; SC2013.38.89, incomplete upper medial tooth; SC2013.38.90, lower medial tooth; SC2013.38.91, lower distal-most lateral tooth; SC2013.38.92, upper distal-most lateral tooth; SC2013.38.93, five lower distal-most laterals; SC2013.38.94, 12 upper distal-most lateral teeth; SC2013.38.95, lateral tooth; SC2013.38.96, five lateral teeth; SC2013.38.97, 87 incomplete medial teeth.
Remarks —We assign 275 teeth in our sample to Pseudaetobatus. Upper median teeth of Pseudaetobatus are wide and straight (Fig. 7F), whereas median teeth from the lower dental battery are more arcuate (Fig. 7G). Median teeth are easily distinguished from those of Aetomylaeus (see above) in that the labial and lingual crown faces are only weakly ornamented (as opposed to heavily pitted labially and with granular texture lingually) and the lingual ridge at the crown/root junction is thick and rounded instead of thin and sharp. These features can also be used to distinguish the lateral teeth of both species, and the distal-most lateral teeth of Pseudaetobatus are also sinuous (Fig. 7I).
Pseudaetobatus has only recently been formally reported from the United States, with two new species described by Cicimurri and Ebersole (2015). Pseudaetobatus belli Cicimurri and Ebersole, 2015 is an early Eocene species that occurs in Mississippi and Alabama, whereas Ps. undulatus is thus far only known from the upper Eocene Dry Branch Formation of South Carolina.
