description: Introduction: Myocardial Infarction (MI) is the leading cause of premature death worldwide. During MI-induced ischemia, the release of heat shock proteins (HSPs), a classic damage-associated molecular pattern (DAMP), by severely injured cells leads to prolonged inflammation through their activation of innate pattern recognition receptors, fibrosis, and subsequent contractile dysfunction. The regulation of HSPs is orchestrated by its master transcription factor, Heat Shock Factor 1 (HSF1). However, it is unknown if HSF1 is a potential integrated functional target to improve MI outcomes. We addressed this question by asking if the coordinated modulation of HSPs via genetic deletion of Hsf1 can be beneficial in MI. Hypothesis: We hypothesized that genetic deletion of Hsf1 can lead to improved survival and left ventricle (LV) remodeling through reduction of pro-inflammatory pathway activation in a murine model of MI-induced coronary artery ligation. Methods and Results: Eleven to thirteen-week-old male Hsf1-/- mice and Hsf1+/+ littermate controls were subjected to MI by left anterior descending (LAD) coronary artery ligation or sham operation. Hsf1-/- mice subjected to induced-MI had a significant higher survival rate (74%) at 28 days than WT mice post-MI in the same time frame (34%, p<0.001). Echocardiography at 3, 7, and 28 days post-MI; however, did not identify any difference in LV function between Hsf1+/+ and Hsf1-/- mice. Masson Trichrome and Picro Sirius Red staining of heart tissue sections following 7 days of sham or MI-operation indicated that MI-operated Hsf1-/- hearts had a significant smaller infarct size than Hsf1+/+ hearts at 19% compared to 32% (p<0.05), respectively; and less collagen deposition when compared to WT littermates. Cardiac expression of heat shock proteins was significantly lowered in the Hsf1-/- hearts compared to Hsf1+/+ hearts following 3 and 7 days of MI. However, no significant difference was observed in number of immune cells, cardiac gene expression of pro-inflammatory cytokines and chemokines, cardiac protein expression of NF-κB and MAPK-ERK1/2 signaling proteins, and serum IL-6 concentration between Hsf1+/+ and Hsf1-/- mice 3 days post-MI. Following 7 days of MI, there is a significant increase in the gene expression of pro-inflammatory cytokines, such as Il1b, and chemokines, such as Ccl2, in Hsf1-/- hearts than Hsf1+/+ hearts. Conclusion & Future Directions: Overall, the loss of Hsf1 improved survival and reduced infarct size following MI. However, its deletion did not affect inflammatory processes until 7 days post-MI or improved cardiac function in our specific murine MI model.

Abstract

Sub-Saharan Africa requires affordable, reliable, and sustainable electricity to boost its economic, social, and human development. The main challenge posed to the region's electricity sector is the large investment gap needed to finance new power projects. The employment of new and innovative financing options is required to bridge this investment gap. Independent power projects have become one of the fastest-growing sources of new finance in the region. However, their development is constrained by the limited availability of debt finance for project implementation. The limited capital and bureaucratic burden of traditional financial institutions coupled with the high risks in the region ensures that the debt finance required by independent power projects is raised only after an arduous voyage and at high interest rates. We address these challenges by proposing a novel decentralized finance instrument, a blockchain special purpose vehicle that streamlines the processes in the financial layer of a traditional special purpose vehicle - finance mobilization, revenue collection, and revenue disbursal. Specifically, the proposed decentralized finance instrument facilitates the mobilization of finance for the special purpose vehicle from a location-independent crowd, revenue collection from the electricity offtaker in a risk-mitigated manner, and disbursal of eventual project revenues to investors.

description: The effects of crude and dilutions of aqueous methanolic and n-hexane extracts of Uvaria chamae (roots and leaves), Spondias mombin (leaves and bark) and Combretum racemosun (Leaves) on pathogenic Candida albicans and Aspergilus niger was studied. The aim was to contribute to the search for a cheaper, conventional cure for both fungi. Phytochemical analysis revealed varying degrees of alkaloids, glycosides, saponin, lipid and oil, tannins, flavonoids, terpenoids and acids. Agar diffusion method was used for antifungal assay. Minimum inhibitory concentration (MIC) used was 10mg/ml of extract and dilutions of the non polar solvents of 10-1 and 10-2 was used. Results showed that none of the plant parts was active against Aspergillus niger. Combretum racemosum had no antifungal effect on tested organisms as well as the different dilutions. However crude methanolic extract of Uvaria (roots and leaves), sponDias (bark and leaves) and n-hexane extracts of Uvaria (leaves and roots) produced anticandidal effects with diameters in this order 14.67±0.71mm, 10.67±0.52mm, 11.00±0.47mm, 15.00±0.47mm and 14.67±0.72mm respectively. Some of the plant parts especially Uvaria had zones of inhibition at a confidence limit comparable with control drug which is ketoconazole and it had inhibitory effects at a diameter of 20.06±0.40mm.

description: This document contains results in a couple of nonrelated areas of geometric group theory. What follows are abstracts for each part.  Let Mi and Ni be path-connected locally uniquely geodesic metric spaces that are not points and f :  ?mi=1Mi ? ?ni=1 Ni be an isometry where  ?ni=1 Ni and ?mi=1Mi are given the sup metric. Then m = n and after reindexing Mi is isometric to Ni for all i. Moreover f is a composition of an isometry that reindexes the factor spaces and an isometry that is a product of isometries fi : Mi ? Ni.  Given a geometric amalgamation of free groups G and the associated simple thick two-dimensional hyperbolic piecewise manifold M, the visual boundary ?M  is a complete quasi-isometry invariant. This invariant can be effciently computed for any G using an adaptation of Leighton's Theorem.  Let G and G0 be geometric amalgamation of free groups with a single Z vertex. If the associated simple thick two-dimensional hyperbolic piecewise manifolds M  and M0 have the same Euler characteristic, then G is commensurable to G0 if and only if M and M0 are homeomorphic. The proof is then extended to the case  where G and G0 have more than a single Z vertex, but more conditions have to be placed on G and G0. With these results an elementary example of two geometric  amalgamations of free groups that are quasi-isometric but not commensurable can be given.

Hyperpolarization

description: This work presents the results of various investigations using various techniques of hyperpolarizing the nuclei of atoms. Hyperpolarization implies magnetic order in excess of the thermal order obtained naturally as described by Curie's law.  The main portion of this work presents the results of a detailed experimental exploration of predictions arising from a new model of transverse nuclear spin relaxation in quantum systems, based on possible manifestations of microscopic chaos in quantum systems. Experiments  have been carried out on a number of hyperpolarized xenon samples, each di ering in its relative percentage of xenon isotopes in order to vary the homonuclear and heteronuclear dipole couplings in the spin system. The experiments were performed under a variety of  conditions in an attempt to observe the behaviors predicted by the model. Additionally, much more extensive measurements were made on a number of samples of solid CaF2 in both single crystal and powder forms. These samples, although thermally polarized, were observed with superior signal to noise ratios than even the hyperpolarized xenon solids, allowing for more precise measurements for comparison to the theory. This work thus contains the  rst experimental evidence for the majority of the model's predictions.  Additionally, this work contains the  rst precise measurements of the frequency-shift enhancement parameters for 129Xe and krypton in the presence of spin-polarized Rb. The determination of these important numbers will be useful to many groups who utilize spinexchange optical pumping in their labs. This work built on the prior knowledge of a precise number for the frequency-shift enhancement parameter of 3He in Rb vapor.  Finally, I detail work using NMR to detect nuclear-spin polarization enhancement in silicon phosphorus by a novel, photo-induced hyperpolarization technique developed by the Boehme research group at the University of Utah. Signiif cant nuclear polarization  enhancements were observed by the Boehme group due to electron-photon interactions in semiconductor soilds; these enhancements were observed by their e ffects on the ambient electrons and measured with electron spin resonance techniques. The work described here  details experiments to observe the enhanced nuclear polarization by directly measuring the intensity increase in an NMR measurement.
Biodegradable multiblock copolymers for gene delivery

Block copolymers

description: Nonviral gene delivery has developed into a promising alternative to viral gene delivery and has the potential to correct many genetic disorders as well as to treat acquired diseases. However, the cytotoxicities related to the high charge densities of effective high molecular weight cationic polymers represent a major hurdle to the development of gene delivery systems that limits their clinical applicability. Thus, the purpose of this research was to develop biodegradable high molecular weight multiblock copolymers (MBC). The polymers consist of repeating blocks of low molecular weight poly(ethylene glycol) (PEG) and poly(L-lysine) (PLL). PLL was used as the DNA condensing agent and PEG was used to provide steric stabilization of the polymer/pDNA complexes as well as to introduce the biodegradable ester bonds onto the backbone of the MBC. The histidine derivative, JV, JV-dimethylhistidine, was conjugated at various mol % to the primary e-amines of PLL to produce the final PEG-PLL-g-NHis MBC, for endosomal buffering.  The first section of this dissertation deals with synthesis and characterization of the conjugates PEG-PLL-g-5 % NHis, PEG-PLL-g-9 % NHis, PEG-PLL-g-16 % NHis, and PEG-PLL-g-22 % NHis MBC. The results showed that the 16 % conjugated MBC produced the highest transfection efficiency with the least cytotoxicity as compared to PLL 25000. Characterization of this optimized conjugate showed that the pK of the imidazole ring was ~4.75 and the polymer degradation half-life (ti/2) was ~5 h in buffer.  Thus, the MBC were shown to be effective and biocompatible polymers for gene delivery.  The second half of the research deals with degradation studies of the MBC and biodistribution in mice. The results showed that there was no significant degradation at low pH, decreased polymer t\a in 10 % mouse serum of ~2 h, and polymer degradation within complexes occurred between 4-8 h in 10 % mouse serum. Biodistribution data revealed that the complexes are able to circulate in the blood for up to 3 d, which was reflected in the various organs. The data suggest that PEG was able to provide steric stabilization by promoting the favorable binding of dysopsonins that prevent uptake by the reticuloendothelial system (RES).

description: Multiple-input and multiple-output (MIMO) technique has emerged as a key feature for future generations of wireless communication systems. It increases the channel capacity proportionate to the minimum number of transmit and receive antennas. This dissertation addresses the receiver design for high-rate MIMO communications in  at fading environments. The emphasis of the thesis is on the cases where channel state information (CSI) is not available and thus, clever channel estimation algorithms have to be developed to bene t from the maximum available channel capacity. The thesis makes four distinct novel contributions. First, we note that the conventional MCMC-MIMO detector presented in the prior work may deteriorate as SNR increases. We suggest and show through computer simulations that this problem to a great extent can be solved by initializing the MCMC detector with regulated states which are found through linear detectors. We also introduce the novel concept of staged-MCMC in a turbo receiver, where we start the detection process at a lower complexity and increase complexity only if the data could not be correctly detected in the present stage of data detection. Second, we note that in high-rate MIMO communications, joint data detection and channel estimation poses new challenges when a turbo loop is used to improve the quality of the estimated channel and the detected data. Erroneous detected data may propagate in the turbo loop and, thus, degrade the performance of the receiver signi cantly. This is referred to as error propagation. We propose a novel receiver that decorrelates channel estimation and the detected data to avoid the detrimental e ect of error propagation. Third, the dissertation studies joint channel estimation and MIMO detection over a continuously time-varying channel and proposes a new dual-layer channel estimator to overcome the complexity of optimal channel estimators. The proposed dual-layer channel estimator reduces the complexity of the MIMO detector with optimal channel estimator by an order of magnitude at a cost of a negligible performance degradation, on the order of 0.1 to 0.2 dB. The fourth contribution of this dissertation is to note that the Wiener  ltering techniques that are discussed in this dissertation and elsewhere in the literature assume that channel (time-varying) statistics are available. We propose a new method that estimates such statistics using the coarse channel estimates obtained through pilot symbols. The dissertation also makes an additional contribution revealing di erences between the MCMC-MIMO and LMMSE-MIMO detectors. We  nd that under the realistic condition where CSI has to be estimated, hence the available channel estimate will be noisy, the MCMC-MIMO detector outperforms the LMMSE-MIMO detector with a signi cant margin.

description: This study develops and applies a concept of combining marginal cost and reliability in an operational water supply model. This concept can be used to gauge the performance of various water supply strategies. Traditional methods of water supply planning typically capture capital costs of new supplies but do not necessarily capture  measurements of reliability and operational efficiencies. Reliability and efficiency can  significantly impact performance of producing and delivering water. Rapid population growth, climate change, extended droughts, and increasing public scrutiny are all reasons why it is becoming more important for water supply planners to develop strategies that provide reliable and cost-efficient solutions to the public. Based on a concept previously developed, this study uses an approach of assessing reliability of water supply and  marginal costs by incorporating both supply and demand-side management options.  Risk-based reliability of the system is estimated as a function of shortages in flow rate  and system storage volumes. The new approach is applied to a water supply planning model for the Washington County Water Conservancy District (District), a regional water wholesaler located in St. George, Utah. The results of this study show that  increased operational efficiencies can be found while maintaining higher reliability in the  system. The results also show that this approach can provide better insight into timing of  large future supply acquisitions.
Laboratory and numerical modeling used to characterize leakage in underground coal mines

description: Stoppings and other control devices used in underground mines can be viewed as air paths with high resistance. The amount of air that leaks through these devices depends on various factors including the type of construction materials used, workmanship, and  stopping inspection and maintenance. Improperly constructed and poorly maintained structures will significantly lower this resistance and cause undue leakage.   The circumstances of a real-world mine rarely exhibit the ideal conditions needed to obtain the most accurate measurements. The airflows and pressure drops in an  underground mine are subject to considerable variation due to movement of equipment, opening of vent doors, and other changes. In addition, mine layouts are often extremely complex and may be such that the airflow profile at the location where a measurement is required is not fully developed. This can make it so that fluid-flow laws are not truly applicable. Nevertheless, a practical effort must be made.  In ventilation planning, resistance values are often measured in the field or in an experimental lab. These measurements were used in a simulated model which was calibrated to match the field conditions. This calibrated model was then used to further evaluate the pressure/quantity requirements for future mining scenarios.  Experimental tests conducted at the University of Utah's coal mine model indicate that for a set of similar stoppings, the trend of pressure drop across the stoppings decreases with distance from the main fan. The trend resembles an exponential decay curve more than a linear one. The resistance values measured in the lab are directly correlated to real world measurements by a physical scale factor of 1:625.  A CFD model was calibrated to within 5% of the lab measurements. Additional analyses with the CFD model also indicated that with increasing distance from the fan,  both pressure drop and leakage flow through the stoppings exhibit an exponential decay function. A single main fan system was compared with a system having a main fan plus a booster fan. The results indicate that the booster fan creates a substantial reduction in pressure drop across the stoppings and a reduction in leakage as well.  A VNETPC model of a two-entry development section was used to further characterize leakage flow in terms of progressive mine development, building materials used, and engineering design strategies. From these analyses, a recommended method of prioritizing life of mine engineering designs and leakage reduction methods to be focused in the critical leakage areas was developed. These critical leakage areas are identified as a proportional distance from the main fan. This method is applicable to existing large or extensive mines as well as future projects.

Finding a fit : choice of a health care provider by childbearing women
Creators: name: Callister, Lynn Clark
Publisher: name: University of Utah
Year: 2012
Subjects: Prenatal care

description: The purpose of this study was to generate a grounded theory explaining the decision making processes used by childbearing women to choose a primary health care provider. One of the maternal tasks of pregnancy is to seek safe passage for the mothers and their unborn children. Health care providers play an important role in the childbearing experience by sharing information, giving support, providing access to resources, and providing care during childbirth. Linkages have been demonstrated between the use of health care services during pregnancy and subsequent interactions with the health care delivery system. There is a paucity of literature on the processes childbearing women as consumers of health care go through in choosing a caregiver. In this study, 30 women were interviewed during pregnancy and following childbirth about their choice of health care providers. These interviews captured the decision making process. Demographic data were analyzed using descriptive statistics. Qualitative data analysis was done using constant comparative analysis. Comparisons were made within and across interviews in a concurrent process of data collection and analysis. Trustworthiness of the data was established. The decision making process was framed by access issues, including financial constraints such as health insurance coverage and nonfinancial constraints such as the availability of caregiver specialty, availability of a certain caregiver, and the desire for a caregiver of a specific gender. The basic social process identified was finding a fit with the choice of a health care provider, which has cognitive and affective components and may be an active or passive process. Processes contributing to finding a fit included (1) making the choice by consulting other women and verifying the choice; (2) confirming the choice by checking out the caregiver, then feeling comfortable or making a change; and (3) reconciling expectations with reality following childbirth as the women evaluated their experience with their caregiver. Women felt satisfied or resolved to make a change. Gaining insight into the processes used by women to choose a health care provider makes an important contribution to the body of knowledge of women's health, with the potential to improve the quality of life for women and their families.

description: Like scientists in virtually every field, astronomers are struggling under a “data deluge”. While the ever-larger images obtained by the newest observatories lead to cutting-edge science, they also overwhelm traditional tools designed to work with files hundreds or thousands of times smaller than the state-of-the-art. In particular, astronomers are rapidly losing the ability to simply look at the images of the sky that are coming out of their telescopes. The FastTract Project solves this problem by marrying existing Web-based visualization technologies in the AAS WorldWide Telescope software system with new features and tools needed to efficiently work with the large astronomical images of the 2020's, enabling US astronomers to fully exploit their world-class facilities.

Numerical and analytical assessment of radon diffusion in various media and potential of charcoal as radon detector

Radon diffusion

description: Numerical assessments of radon diffusion together with analytical estimates for short-time and long-time exposure were the first objective of this thesis with the goal to demonstrate how radon propagates in various media. Theoretical predictions were compared to numerical simulations, and obtained values of total radon activities inside each material match quite well with the analytical estimates. These estimates, for activated and nonactivated charcoal, were then used to evaluate the possibility of designing a charcoal system to be used as a radon detector. Another objective was to use nonactivated charcoal samples and measure the level of radon accumulation, and use these data to estimate radon diffusion and adsorption coefficients. The analytical approach was developed to estimate these values. Radon adsorption coefficient in nonactivated charcoal was found to be from 0.2 to 0.4 m3/kg. Radon diffusion coefficient for nonactivated charcoal is in the range of 1.2*10-11 to 5.1*10-1° m2/s in comparison to activated charcoal with adsorption coefficient of 4 m3/kg and diffusion coefficient of 1.43*10-9 m2/s. The third objective was to use GEANT4 numerical code to simulate decay of 238U series and 222Rn in an arbitrary soil sample. Based on that model, the goal was to provide a guideline for merging GEANT4 radioactive decay modeling with the diffusion of radon in a soil sample. It is known that radon can be used as an earthquake predictor by measuring its concentration in groundwater, or if possible, along the faults. Numerical simulations of radon migration by diffusion only were made to estimate how fast and how far radon can move along the fault strands. Among the known cases of successful correlations between radon concentration anomalies and earthquake are the 1966 Tashkent and 1976 Songpan-Pingwu earthquakes. Thus, an idea of radon monitoring along the Wasatch Fault, using system of activated/nonactivated charcoals together with solid state radon detectors is suggested in the thesis. Also, the use of neutron activation analysis for soil samples, collected along and away from Wasatch Fault, and looking for the trace elements can result in correlation with earthquakes, occurred in the past. This approach can be used for earthquake prediction in future. iv

description: The problem of poor compliance to medication regimens is significant in health care because it is a fundamental part of treatment in Western medicine.  External barriers to compliance include financial constraints, language or other communication problems, issues surrounding patient education and culture, and depression.  In order to collect information regarding individual perceptions on compliance, a qualitative approach was determined to be the most appropriate research methodological approach.  The overall purpose of this qualitative study was to increase the knowledge base about perspectives of patients who are part of an underserved population regarding the treatment of their chronic illness with medications.  The study consisted of semi-structured interviews, and content analysis was used to analyze the data.  An interview method was selected because the research anticipated that each patient would come with his/her own paradigms and health beliefs.  Individuals recruited for the study included those with chronic illnesses comprising diabetes, asthma, and hypertension.  Participants were selected from a local community health center.  From the 9 participants, 15 chronic illnesses were represented.  Mean yearly income was $10,300.  The participants of this study viewed themselves as compliant with their medication regimens as they were doing what they could to feel well, in spite of facing many barriers. Factors that may have affected participants' compliance with their treatment regimens were identified: deficient finances, health literacy (or a persons' inability to perform basic reading and numerical tasks required to function in the health care environment), a focus on symptom management rather than preventative measures, difficulties during times of change, and participant's attitude.  Helping patients overcome the barriers they face, as they approach their medication regimen starts with understanding each patient's personal experiences and paradigm.  Although patients are ultimately responsible for their own health care, the providers who attend to them should work to gain a patient perspective on recommended treatments rather than simply applying the concept and assumptions inherent in the construct noncompliance.

description: In this descriptive study, the incidence of hemorrhage following two methods of nursing management (Method A and Method B) was compared.  Method A ( sandbag) involved placing a pressure dressing and a sandbag on the catheterization site, after removal of the catheter from the femoral artery.  Method B (pressure) involved placing manual pressure for so minutes on the catheterization site after removal of the catheter from the femoral artery.  The population (N = 29) consisted of patients undergoing femoral artery catheterization.  The subjects were managed, after their catheterization, following either musing management Method A (sandbag) or nursing management Method B (pressure).  The catheterization site and any dressing, was observed for evidence of post-catheterization hemorrhage.  If bleeding occurred, the time it occurred and surrounding circumstances were recorded.  The major finding was one incident of post-catheterization hemorrhage in Method B (pressure).  This did not have any significance and the methods were determined to be equal in terms of patient safety.  Method A (sandbag) was determined to be desirable in terms of potential post-effectiveness, and management of musing time.

description: This dissertation presents and analytic method to determine the extent to which interalveolar diffusion can influence pulmonary gas exchange in response to graded vascular embolization.  The method shows that failure of inert gas techniques to detect microemboli is due to interalveolar diffusion of inert tracer gases, and demonstrates that microembolic involvement is detectable with the added use of the less diffusible stable isotopes 18O2 and 13CO2.  An animal study utilizing two sets of physiologic/inert gas pairs (18O2/acetylene, and 13CO2/dimethyl ether) is presented.  Spherical polystyrene beads (diameter 50-500 µm) were injected into anesthetized dogs to induce microembolism.  Gas exchange was assessed using the synchronous tracer injection method.  In addition to being consistent with the model predictions of the interalveolar, diffusion, the results show sufficient separation in the two gas pairs to suggest feasibility for utilizing the method as a noninvasive means for quantitating both embolic dimension and the extent of involvement throughout the lung.  Implications for involvement in human subjects are discussed.
Thermal solvent extraction of a sunbury oil shale kerogen

Subjects: Shale oils, refining

description: Thermal solution of an aromatic Sunbury oil shale kerogen was studied using three solvents: toluene above its critical temperature, methylcyclohexane above its critical temperature, and tetralin at subcritical temperatures. Sixty-six thermal solutions tests were conducted which included twenty-nine isothermal tests using all three solvents and thirty-seven linear-heating tests using tetralin. Maximum kerogen conversions to soluble products, as determined by low temperature ash analyses, were 49% for extraction with toluene (37% above Fischer assay oil yield on a water-free basis), 58% for extraction with methylcyclohexane (69% above Fischer assay oil yield), and 80% for extraction with tetralin (150% above the oil yield from Fischer assay). The results confirmed observations of previous investigators of the importance of available hydrogen during thermal solution of highly aromatic eastern U.S. oil shales. Product coking appeared to be especially prevalent in extractions with hydrogen-

Arbeitszeitstudien

description: Die Arbeitszeit von Lehrkräften in Deutschland wird durch ein Deputat-Stundenmodell geregelt. Lehrkräfte sollen durch ihr besonderes Arbeitszeitmodell nicht schlechter gestellt werden, als andere Beschäftigte des Öffentlichen Dienstes. Zur Ermittlung der Arbeitszeit von Lehrkräften sind daher seit den 1950er Jahren etwa zwanzig wissenschaftliche Studien in Deutschland durchgeführt worden. Nach einer Einführung in den Gegenstand und Überblick über die Perioden der Arbeitszeitgestaltung analysiert die Expertise im Auftrag der Max-Träger-Stiftung die vorliegenden Forschungsergebnisse zur Arbeitszeit. Für den systematischen Vergleich wird in der Metastudie ein umfangreiches Analysekonzept entwickelt, welches sowohl die Methoden der Ermittlung, als auch die erzielten Ergebnisse vergleichbar macht und auswertet.Die Studie kommt zu einem doppelten Ergebnis: Erstens haben die Methoden der Arbeitszeiterfassung einen Stand erreicht, wo durch das Zusammenspiel von juristischer Entwicklung und Weiterentwicklung der Erfassungsmethoden die Arbeitszeit heute ausreichend genau bestimmbar ist. Der Gesetzgeber und die Sozialparteien sind handlungsfähig und aufgerufen die Arbeitszeit zu gestalten. Zweitens zeigt die inhaltliche Auswertung, dass trotz erheblicher Veränderungen in den Schulen und ihren Rahmenbedingungen zentrale Befunde in der Substanz immer wieder bestätigt wurden: Lehrkräfte sind aufgrund zu hoher Arbeitszeitvorgaben gegenüber vergleichbaren Beschäftigten im Öffentlichen Dienst schlechter gestellt. Es lassen sich bestimmte Einflussfaktoren auf die Arbeitszeit identifizieren und in ihrer Bedeutung grob quantifizieren. Zudem existieren extreme Streuungen in der Arbeitszeit zwischen einzelnen Lehrkräften. Auf der anderen Seite wurden relevante neue Trends identifiziert, die neue Wege in der Arbeitszeitgestaltung eröffnen: Der Anteil des Unterrichtens hat sich über die Jahrzehnte reduziert, während nicht unmittelbar unterrichtsbezogene Tätigkeiten zugenommen haben. Der Forschungsstand zeigt ferner, dass professionelle Einstellungen, Kompetenzen und Arbeitsbezogene Verhaltens- und Erlebensmuster ebenfalls einen bedeutenden Einfluss auf die Länge der Arbeitszeit haben. Zum Abbau von bekannten quantitativen und qualitativen Belastungen sind deutliche arbeitspolitische Maßnahmen erforderlich. Arbeitszeitpolitik von Lehrkräften darf sich aber auch nicht auf die Gestaltung der Rahmenbedingungen beschränken, sondern muss ebenso die Möglichkeiten gesundheitsförderlichen Verhaltens und verantwortlicher Arbeitsteilung in den Schulen mit in den Blick nehmen.

description: An improved method for the [2+2+2] cycloaddition of diynes with CO2 to synthesize pyrones was developed using a Ni/NHC catalyst system. The new catalyst  system boasts improved yields, lower reaction temperatures, and lower reaction pressures compared to the previously known methods. Furthermore, certain  unsymmetrical diynes could be employed in the reaction to generate a single pyrone regioisomer. Extensive studies suggest that the regioselectivity arises from steric  interactions between the NHC ligand and the substituents on the alkyne termini.  In an effort to synthesize pyrans, attempts at cyclizing aldehydes and ketones with diynes and enynes were made. When aldehydes and diynes were employed, the  expected pyran cycloadduct was not obtained. Instead, the [3,3] electrocyclic ring opened tautomer was obtained. The use of enynes with aldehydes prevented this tautomerization, but the synthesis of the desired pyran was highly substrate dependent due to competitive side product formation.  The use of ketones and enynes in the cycloaddition allowed for the chemoselective formation of dihydropyrans in excellent yields. However, it was  necessary to carefully tune the reaction conditions to each particular substrate in order to achieve high yields. Nonetheless, this represents the first [2+2+2] cycloaddition of ketones and enynes.   Due to the air sensitivity of the Ni(0) precursor and the carbene ligand, a method was devised for generating the active catalyst in situ from air stable precursors. While  this method worked very well for the cyclization of diynes and nitriles, the coupling of diynes with CO2, aldehydes, and isocyanates was less successful.  The Ni/NHC cycloisomerization of enynes to 1,3-dienes was also discovered. While the yields of this reaction were excellent, the substrate scope was limited.  Attempts at improving the system were initiated though an in-depth study reaction mechanism. Deuterium labeling experiments suggest that the active catalyst is formed by an unprecedented C-H activation of the carbene ligand by the Ni(0).

description: The current study examined over 3000 visual images on the homepages of 234 National University to determine how power relations are depicted. Using a hybrid  methodology of grounded theory, critical discursive analysis, and facial prominence scoring, the work culminates in a theory: The (Im)Balanced Theory of College Identity Formation Online. The theory holds that colleges used different tactics, strategies, and  resources when depicting various subject positions on their homepages.
