Customs, places and 'gentes' in Plautus.
Creators: name: Levis, Richard.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1998
Subjects: subject: Literature, Classical.

description: This dissertation examines the cultural constructs that are the basic elements of the comedies of Plautus. To achieve this goal the study has been divided into four chapters: Language, Customs, Places and 'Gentes'. Chapter One, Language, analyzes how the Latin language influences the way in which the characters express the various aspects of their world. Chapter Two, Customs, considers the expression of the affairs of daily life that are of common interest to the characters on stage. This chapter evaluates a cross-section of the activities that the characters describe, such as their reference to public offices and civic duties, the details of their religious practices, their dealings with wealth and money, as well as their references to travel, education and slave duties. Chapter Three, Places, looks at the wide variety of places that construct the world of Plautus' characters. This chapter is divided into three parts: the city sites, the dramatic settings, and the distant countries and cities of the world. Chapter Four, 'Gentes', examines the manner in which Plautus ascribes his characters and the people of the world into particular groups and what variation and importance there are in these attributes and specifications. The comedies of Plautus are filled with descriptions of cultural details that are evidence for some of the ways in which Latin-speaking peoples of the Middle Republican period conceptualized the world. The cultural resonance of the Latin language influences how the characters express important elements of their stage world. This influence is especially acute in the moral and familial terms that the characters use, but it filters through as well into the political world of the comic stage and other customs that are a part of the characters' interactions. Furthermore, the places that the characters of the comic stage describe maintain certain consistent associations which allows for an easy identification from play to play as well as an easy transition from the stage to the places with which the audience was familiar. Finally, Plautus draws upon a fairly narrow band of ethnic characterizations which he applies to the gentes who populate his plays. Many of these attributes follow the themes of comedy itself. Otherwise, the designation of origin is an important attribute that is tied to a character's social status and birthright as a free citizen. Plautus' characters are citizens from all over the Mediterranean world and this fact plays an important role in the development of the plots of the plays and in most of their resolutions.

description: Phthalaldehyde was found to react with nitro-methane, in methanolic solution and in the presence of sodium methoxide, to give the sodium salt of 2-aci-nitro-indandiol-1,3. It was found that this salt, on acidification with ion exchange resin, afforded a mixture of 2-nitro-indandiol-1,3 and 2-nitroindenol-3, which were separated by fractional crystallisation. The structures of the compounds obtained were established by nuclear magnetic resonance spectroscopy. Hence, the applicability of phthalaldehyde in the condensation with nitromethane, to form a five-membered carbocyclic ring, was nitromethane, to form a five-membered carbocyclic ring, was shown. On the other hand, when the reaction between phthalaldehyde and nitromethane was carried out without solvent, in the presence of sodium carbonate, the hemiacetal of 2-(1-hydroxy-2-nitroethyl)-benzaldehyde was exclusively formed. The structure of the latter was proved by means of chemical transformations leading to the isoquinoline system. For the study concerning the closure of a seven-membered ring, adipic aldehyde was chosen. Under all conditions investigated, no formation of a seven-membered carbo-cyclic ring was noticed. It is believed that the failure was due to a more rapid formation of other compounds, namely 1,8-dinitrooctane-2,7-diol and the product of internal aldol condensation of adipic aldehyde, cyclopentene-1-aldehyde.

description: This report from the International Consortium on Hallucinations Research considers the current status and future directions in research on psychological therapies targeting auditory hallucinations (hearing voices). Therapy approaches have evolved from behavioral and coping-focused interventions, through formulation-driven interventions using methods from cognitive therapy, to a number of contemporary developments. Recent developments include the application of acceptance- and mindfulness-based approaches, and consolidation of methods for working with connections between voices and views of self, others, relationships and personal history. In this article, we discuss the development of therapies for voices and review the empirical findings. This review shows that psychological therapies are broadly effective for people with positive symptoms, but that more research is required to understand the specific application of therapies to voices. Six key research directions are identified: (1) moving beyond the focus on overall efficacy to understand specific therapeutic processes targeting voices, (2) better targeting psychological processes associated with voices such as trauma, cognitive mechanisms, and personal recovery, (3) more focused measurement of the intended outcomes of therapy, (4) understanding individual differences among voice hearers, (5) extending beyond a focus on voices and schizophrenia into other populations and sensory modalities, and (6) shaping interventions for service implementation.

description: In the pursuit of enhancing the separation efficiency of trivalent actinides and lanthanides, specifically within the ALSEP process, this study delves into the exploration of scaffold preorganization in diglycolamide (DGA) ligands. Such preorganization is expected to impact the kinetic inertness and radiation resistance of f-element-extractant complexes. A key innovation involves the incorporation of a pyridine moiety into the DGA backbone, offering additional coordination sites and potentially improving metal-ion selectivity through chelation changes. This research led to the synthesis and structural characterization of six novel DGA ligands: N,N,N’,N’ tetra-hexyl pyridine diglycolamide, N,N,N’,N’ tetra-hexyl benzene diglycolamide, N,N,N’,N’ tetra-octyl pyridine diglycolamide, N,N,N’,N’ tetra-octyl benzene diglycolamide, N,N,N’,N’ tetra-decyl pyridine diglycolamide, and N,N,N’,N’ tetra-decyl benzene diglycolamide were synthesized and structurally characterized by 1H and 13C NMR analysis. Two asymmetric analogs of the novel ligands, N,N’- dimethyl N,N’- dihexyl pyridine diglycolamide and N,N’- dimethyl N,N’- dihexyl benzene diglycolamide, were synthesized and analyzed to investigate the role of asymmetry of the alkyl chain on solubility and selectivity. Initial liquid-liquid extraction experiments focused on lanthanides, particularly the critical elements neodymium (Nd) and dysprosium (Dy). Mixtures were analyzed using inductively coupled plasma optical emission spectrometry (ICP-OES), allowing for the determination of distribution factors for lanthanide ions and the exploration of initial separation factors for each lanthanide pair. This study not only contributes to a deeper understanding of separation processes vital to critical materials and the nuclear fuel cycle but also provides valuable insights into the design of more efficient extractants for trivalent elements.

description: Background Disrupted bile secretion leads to liver damage characterized by inflammation, fibrosis, eventually cirrhosis, and hepatocellular cancer. As obstructive cholestasis often progresses insidiously, markers for the diagnosis and staging of the disease are urgently needed. To this end, we compiled a comprehensive data set of serum markers, histological parameters and transcript profiles at 8 time points of disease progression after bile duct ligation (BDL) in mice, aiming at identifying a set of parameters that could be used as robust biomarkers for transition of different disease progression phases. Results Statistical analysis of the more than 6,000 data points revealed distinct temporal phases of disease. Time course correlation analysis of biochemical, histochemical and mRNA transcript parameters (=factors) defined 6 clusters for different phases of disease progression. The number of CTGF-positive cells provided the most reliable overall measure for disease progression at histological level, bilirubin at biochemical level, and metalloproteinase inhibitor 1 (Timp1) at transcript level. Prominent molecular events exhibited by strong transcript peaks are found for the transcriptional regulator Nr0b2 (Shp) and 1,25-dihydroxyvitamin D(3) 24-hydroxylase (Cyp24a1) at 6 h. Based on these clusters, we constructed a decision tree of factor combinations potentially useful as markers for different time intervals of disease progression. Best prediction for onset of disease is achieved by fibronectin (Fn1), for early disease phase by Cytochrome P450 1A2 (Cyp1a2), passage to perpetuation phase by collagen1α-1 (Col1a1), and transition to the progression phase by interleukin 17-a (Il17a), with early and late progression separated by Col1a1. Notably, these predictions remained stable even for randomly chosen small sub-sets of factors selected from the clusters. Conclusion Our detailed time-resolved explorative study of liver homogenates following BDL revealed a well-coordinated response, resulting in disease phase dependent parameter modulations at morphological, biochemical, metabolic and gene expression levels. Interestingly, a small set of selected parameters can be used as diagnostic markers to predict disease stages in mice with cholestatic liver disease.

description: Psychological interventions can improve Quality of Life (QoL). Object of interest was if different psychological interventions influence short-term QoL after colonic resection for carcinoma. Furthermore, we wanted to see if there is a correlation between patients` preoperative affect and postoperative QoL. Sixty patients that underwent colorectal surgery were divided into three groups. Group one (n = 20) received Guided Imagery and group 2 (n = 22) Progressive Muscle Relaxation. The third group (Control, n = 18) had no intervention. Quality of Life (QoL) was measured using the EORTC QLQ-C30 and the Gastrointestinal Quality of life Index (GIQLI). Patients' affect was measured by the PANAS questionnaire. The higher the preoperative Negative Affect was, the lower were the scores for QoL on the 30th postoperative day. Patients' QoL was highest preoperatively and lowest on the third postoperative day. On the 30th postoperative day scores for QoL were almost as high as preoperative without difference between the three groups. Neither Guided Imagery nor Progressive Relaxation was influencing short-term QoL measured by the EORTC QLQ-C30 and the GIQLI questionnaire after colorectal surgery for cancer. Screening patients' with the PANAS questionnaire might help to identify individuals that are more likely to have a worse QoL postoperatively.
Studying complement regulation in a C3 glomerulopathy-specific microenvironment

Publisher: name: University of Iowa

Subjects: public abstract

description: The complement system is a cornerstone of the innate immune response: it facilitates pathogen identification and clearance via the self-amplification cascade, while being tightly controlled on host surfaces to prevent tissue damage. C3 glomerulopathy (C3G) is a group of ultra-rare complement-mediated renal diseases. The underlying cause of C3G pathogenesis stems from inadequate control of the alternative pathway (AP) of complement on the surface of glomerular basement membrane (GBM), causing C3 deposition within the GBM. The resulting kidney damage leads to about 50% of C3G patients progressing to end-stage renal disease within 10 years of diagnosis.
description: C3G is a multifactorial disease driven in most patients by autoantibodies against complement proteins and complexes (acquired drivers), and/or pathogenic variation in complement genes (genetic drivers), however, a subset of C3G patients have no identified complement-related drivers of disease. Such heterogeneity of presentations poses a challenge when investigating molecular mechanisms of this disease. This thesis will describe several studies performed with the goal of improving our understanding of C3G pathogenesis within the glomerular microenvironment. Here we present a novel in vitro model of AP activation on human extracellular matrix (ECM) surface, which allowed us to discover a new mechanism wherein autoantibodies against AP C3 convertase mediate C3G pathogenesis, and provided us with a platform to study the effects of ECM remodeling on complement regulation. Taken together, our findings provide insight into our basic understanding of the interplay between the components of complement system and the different microenvironments they act upon, furthering our ability to uncover the unknown drivers of C3G and improve patient outcomes.

description: In contrast to ultraviolet and infrared irradiation, which are known to facilitate cutaneous photoaging, immunosuppression, or tumour emergence due to formation of free radicals and reactive oxygen species, potentially similar effects of visible light on the human skin are still poorly characterized. Using a blue-violet light irradiation source and aiming to characterize its potential influence on the antioxidant status of the human skin, the cutaneous carotenoid concentration was measured noninvasively in nine healthy volunteers using resonance Raman spectroscopy following irradiation. The dose-dependent significant degradation of carotenoids was measured to be 13.5% and 21.2% directly after irradiation at 50 J/cm² and 100 J/cm² (). The irradiation intensity was 100 mW/cm². This is above natural conditions; the achieved doses, though, are acquirable under natural conditions. The corresponding restoration lasted 2 and 24 hours, respectively. The degradation of cutaneous carotenoids indirectly shows the amount of generated free radicals and especially reactive oxygen species in human skin. In all volunteers the cutaneous carotenoid concentration dropped down in a manner similar to that caused by the infrared or ultraviolet irradiations, leading to the conclusion that also blue-violet light at high doses could represent a comparably adverse factor for human skin.

description: Hohe Ammoniakemissionen aus der Tierhaltung sind schädlich für die Umwelt und die menschliche Gesundheit. Daneben haben vor allem Geruchsbelästigungen in der Nachbarschaft die Tierhaltung in den Fokus gesellschaftlicher Diskussionen gestellt. Nach derzeitigem Stand kann Deutschland die gemäß internationaler Verträge geltenden Emissionshöchstmengen für Ammoniak (550 Kilotonnen pro Jahr) mit den in der Vergangenheit beschlossenen Maßnahmen nicht einhalten; zusätzliche Maßnahmen sind erforderlich.In diesem im Auftrag des ⁠UBA⁠ erstellten Gutachten wird die Entwicklung von Abluftreinigungsanlagen (ARA) in Deutschland aufgezeigt. Verfahrenstechniken, Reinigungsleistungen, Zertifizierungskriterien und Anlagenüberwachung werden beleuchtet. Danach gibt es aktuell elf von der Deutschen Landwirtschafts-Gesellschaft zertifizierte Abluftreinigungssysteme für Schweinemast und fünf für Masthähnchen, mit denen sich außer Ammoniak auch Gerüche und Stäube wirksam mindern lassen. Laut Herstellerangaben (2014) wurden seit 1997 über 1.000 ARA für Geflügel und Schweine installiert.Darüber hinaus widmet sich das Gutachten wirtschaftlichen Aspekten. Es beschreibt den Trend in der Schweinefleischerzeugung in Deutschland hin zu einer geringeren Anzahl von Betrieben mit steigenden Betriebsgrößen und insgesamt steigender Produktion mit geringeren Gewinnmargen pro kg verkauftem Schweinefleisch. Die Gutachter kommen zu dem Schluss, dass die unter starkem Kostendruck arbeitenden Schweinemastanlagen auch ohne ARA erst ab 1.500 Mastplätzen mit Gewinn arbeiten. Die Kosten für die ARA verschärfen den Kostendruck geringfügig.Anhand der dargelegten Untersuchung zum Stand der Technik und im Hinblick auf die Tatsache der seit Jahren erfolgreich betriebenen großen Anlagenzahl an Abluftreinigungsanlagen in der Praxis wird untermauert, dass Abluftreinigung in diesem Sektor zu den fortschrittlichsten Verfahren zur Minderung luftgetragener Emissionen gehört und den Stand der Technik markiert.
Modeling and control of large space structures.

Subjects: subject: Engineering, Aerospace.

description: In this thesis a preliminary formulation of large space structures and their stabilization is considered. The system consists of a (rigid) massive body and flexible configurations which consist of several beams, forming the space structure. The rigid body is located at the center of the space structure and may play the role of experimental modules. A complete dynamics of the system has been developed using Hamilton's principle. Euler-Bernoulli, Rayleigh and Timoshenko beam theories are utilized to derive the dynamic equations governing the vibration of the beams. The equations that govern the motion of the complete system consist of six ordinary differential equations and several partial differential equations together with appropriate boundary conditions. The partial differential equations govern the vibration of flexible components. The ordinary differential equations describe the rotational and translational motion of the central body. The dynamics indicate very strong interaction among rigid body translation, rigid body rotation and vibrations of flexible members through nonlinear couplings. Hence any rotation of the rigid body induces vibration in the beams and vice-versa. Also any disturbance in the orbit induces vibration in the beams and wobbles in the body rotation and vice-versa. This makes the system performance unsatisfactory for many practical applications. In this thesis stabilization of the above mentioned system subject to external disturbances is considered. The asymptotic stability of the perturbed system by applying several types of stabilizing controls such as proportional controls, deadzone controls or saturation controls is proved using Lyapunov's method. Numerical simulations are carried out in order to illustrate the impact of dynamic coupling or interaction among several members of the system and the effectiveness of the suggested feedback controls for stabilization. Stability of a spacecraft and a space station under the influence of slew maneuvering is numerically investigated.
Regulation of iron metabolism in radioresistant glioblastoma

Subjects: public abstract

description: Glioblastoma (GBM) is the most common and most lethal adult primary malignant brain tumor. Median progression-free and overall survival after initial diagnosis are 6.2-7.5 and 14-20 months, respectively, even with a highly aggressive standard-of-care treatment. One of the main reasons for this poor survival is development of resistance to standard of care therapy, especially, resistance to radiotherapy. Defining the molecular mechanism(s) responsible for the adaptive radioresistance in GBM is necessary for the development of effective treatment options. The cellular labile iron pool (LIP) is very important for determining the cellular response to radiation, as it contributes to radiation-induced production of reactive oxygen species (ROS). Recently, cytochrome c oxidase (CcO), a mitochondrial heme-containing enzyme also involved in regulating ROS production, was found to be involved in GBM chemoresistance. However, the role of LIP and CcO in GBM radioresistance is not known. Herein, we tested the hypothesis that CcO-mediated alterations in the level of LIP contribute to adaptive radioresistance. Using an in vitro model of GBM adaptive radioresistance, we found an increase in CcO activity in radioresistant cells that is associated with a decrease in the cellular LIP, a decrease in lipid peroxidation and a switch in the CcO subunit 4 (COX4) isoform expression, from COX4-2 to COX4-1. We further observed that radioresistant cells have increased expression of mitoferrin-1 (MFRN1), a protein that facilitates the incorporation of iron into mitochondria. Overexpression of MFRN1 in glioma cells increases the activity of mitochondrial protein complexes, a decrease in cellular LIP, and a decrease in production of 4-hydroxy nonenal (4-HNE), a lipid peroxidation product. Furthermore, MFRN1 overexpression also enhances the proliferation rate and anchorage independent growth. Moreover, MFRN1 overexpression significantly decreased survival in an orthotopic mouse model of glioma. These results indicate that manipulation of cellular and mitochondrial iron homeostasis may provide a novel strategy to improve therapeutic outcome in patients with GBM.

description: Diameters of microvessels undergo continuous structural adaptation in response to hemodynamic and metabolic stimuli. To ensure adequate flow distribution, metabolic responses are needed to increase diameters of vessels feeding poorly perfused regions. Possible modes of metabolic control include release of signaling substances from vessel walls, from the supplied tissue and from red blood cells (RBC). Here, a theoretical model was used to compare the abilities of these metabolic control modes to provide adequate tissue oxygenation, and to generate blood flow velocities in agreement with experimental observations. Structural adaptation of vessel diameters was simulated for an observed mesenteric network structure in the rat with 576 vessel segments. For each mode of metabolic control, resulting distributions of oxygen and deviations between simulated and experimentally observed flow velocities were analyzed. It was found that wall-derived and tissue-derived growth signals released in response to low oxygen levels could ensure adequate oxygen supply, but RBC- derived signals caused inefficient oxygenation. Closest agreement between predicted and observed flow velocities was obtained with wall-derived growth signals proportional to vessel length. Adaptation in response to oxygen- independent release of a metabolic signal substance from vessel walls or the supplied tissue was also shown to be effective for ensuring tissue oxygenation due to a dilution effect if growth signal substances are released into the blood. The present results suggest that metabolic signals responsible for structural adaptation of microvessel diameters are derived from vessel walls or from perivascular tissue.
The reparation of harm: A canonical analysis of canon 128 with reference to its common law parallels.

Subjects: subject: Law.

description: In 1983, a maxim of the natural law was concretized into a canonical obligation requiring one remedy the harm that one inflicts. In addition to canon 128's providing legal encouragement for one voluntarily to remedy the harm that one inflicts, if the person does not act voluntarily, c.128 provides a legal foundation for persons who have been harmed to exercise their right to vindicate and defend their rights in an ecclesiastical forum. It also provides a foundation from which the Church can act to enforce this principle and compel a person to remedy the harm that he or she inflicts. The primary purpose of this work is to explain the meaning of c. 128 and the nature, procedures, and methods of the remedy of harm in canon law. In addition, this work compares canonical concepts with similar concepts found in common law, and distinguishes those concepts that may be foreign to the common law tradition. This work seeks to show that c. 128 has been under-used as a basis for petitioning a canonical forum to remedy unlawfully inflicted harm. It demonstrates that c. 128 can be used as a foundational canon having its own broad applications rather that simply being a philosophical and canonical support for other juridic principles. Furthermore, this work endeavors to contribute to the canonical discussion on how justice is viewed and administered in the Church. Finally, it is hoped that this work will supply a common law perspective to the remedy of harm in canon law, and provide concrete examples from the common law that can aid judges and administrators in assigning fair and equitable remedies to persons that have been harmed.
Detecting DIF in polytomous items: An empirical comparison of the ordinal logistic regression, logistic discriminant function analysis, Mantel, and Generalized Mantel-Haenszel procedures.

description: This study had four main objectives and two minor objectives: (1) To compare the Type I Error rates of four analytic techniques: the Mantel, Generalized Mantel-Haenszel (GMH), Logistic Discriminant Function Analysis (LDFA), and Ordinal Logistic Regression (OLR) procedures when there was no DIF in items. It was hypothesized that the procedures would differ little in their Type I Error rates, but that the OLR would have relatively the lowest Type I Error rates. (2) To compare the power of the Mantel, GMH, LDFA, and OLR for detecting uniform and nonuniform DIF in polytomous items. It was hypothesized that the Mantel would have the highest power for uniform DIF, but that it would not be useful for detecting nonuniform DIF. The GMH, OLR and LDFA were expected to display high power for nonuniform DIF. (3) To learn whether discrimination of the studied item, reference and focal group ability difference, sample size ratio between reference and focal group, and skewness would affect the performance of the four DIF detection procedures. It was hypothesized that differences in group ability distributions would result in increased Type I Error when item discrimination was high, and that differences in sample size ratio would lower power. (4) To determine whether adding a measure of effect size would reduce Type I Error. It was hypothesized that including effect size in the decision rule would reduce Type I Error for all procedures, and that it would also result in slightly lower power. (5) To compare Type I Error of the LDFA and OLR in classifying DIF as uniform when it was nonuniform and (6) To compare the Type I Error of the LDFA and OLR in classifying DIF as nonuniform when it was uniform.

description: Background: Migrant women are over-represented in the sex industry, and migrant sex workers experience disproportionate health inequities, including those related to health access, HIV and sexually transmitted infections (STIs), and violence. Despite calls for occupational sex work interventions situated in labour rights frameworks, there remains a paucity of evidence pertaining to migrant sex workers’ needs and realities, particularly within Mexico and Central America. This study investigated migrant sex workers’ narratives regarding the ways in which structural features of work environments shape vulnerability and agency related to HIV/STI prevention and violence at the Guatemala-Mexico border. Methods: Drawing on theoretical perspectives on risk environments and structural determinants of HIV in sex work, we analyzed in-depth interviews, focus groups, and ethnographic fieldwork conducted with 39 migrant sex workers in indoor work environments between 2012 and 2015 in Tecún Umán, Guatemala. Results: Participant narratives revealed the following intersecting themes to be most closely linked to safety and agency to engage in HIV/STI prevention: physical features of indoor work environments (e.g., physical layout of venue, proximity to peers and third parties); social norms and practices for alcohol use within the workplace; the existence and nature of management practices and policies on health and safety practices; and economic influences relating to control over earnings and clients. Across work environments, health and safety were greatly shaped by human rights concerns stemming from workplace interactions with police, immigration authorities, and health authorities. Conclusions: Physical isolation, establishment norms promoting alcohol use, restricted economic agency, and human rights violations related to sex work policies and immigration enforcement were found to exacerbate risks. However, some establishment policies and practices promoted ‘enabling environments’ for health and safety, supporting HIV/STI prevention, economic agency, and protection from violence and exploitation; these practices and policies were especially crucial for recent migrants. Policy reforms and structural workplace interventions tailored to migrant sex workers’ needs are recommended to promote improved working conditions and migrant sex workers’ health, safety, and human rights.

description: Many public companies have the same investor relations (IR) representative. I study the consequences of this common representation. In difference-in-differences tests, I find common IR representation increases common institutional ownership, overlap in sell-side analyst coverage, and similarities in guidance policies across clients—even among economically dissimilar firms in different industries. Consequently, firms with common IR representation exhibit heightened return comovement. My results suggest that not only is external IR meaningful, but which external IR representative a firm has plays an important role in their connection to the capital markets.

The purpose of this dissertation was to examine whether an individual’s use of cognitive reappraisal (CR) as an emotional regulation strategy, higher PS, and higher EI scores were associated with better team communication, cooperation, and satisfaction within primary healthcare settings. I sent a web based survey to healthcare providers in primary clinics through social media and email. I measured an individual’s ER strategy using the Emotional Regulation Questionnaire (ERQ), PS using the Team Psychological Safety scale (TPS), and EI using the Workgroup Emotional Intelligence Profile (WEIP). I employed bivariate analyses to examine the relationships between ER strategy and team outcomes. Then, I investigated the association of PS and EI with team outcome measures in separate, linear, simple regressions. Finally, I tested multiple regression models of PS and EI with team outcome measures to investigate their relationships further. ER results were non-significant differences in team outcome measures by an individual’s ER strategy. Other results revealed that the TPS and WEIP scores significantly predicted respondents’ team communication, cooperation, and satisfaction reports within their clinics. The results of multiple regression analysis of PS and EI demonstrated a significantly predictive relationship with communication (60.4%), cooperation (65.5%), and satisfaction (66.7%). These findings emphasize the importance of PS and EI in shaping healthcare team experiences. Integrating PS training and EI enhancement programs within healthcare professional curriculums and continuous professional development may strengthen team outcomes within healthcare settings and, therefore, patient-centered care.

description: Introduction Changing the way we make decisions from one environment to another allows us to maintain optimal decision-making. One way decision-making may change is how biased one is toward one option or another. Identifying the regions of the brain that underlie the change in bias will allow for a better understanding of flexible decision-making. Methods An event-related, perceptual decision-making task where participants had to detect a picture of an animal amongst distractors was used during functional magnetic resonance imaging. Positive and negative financial motivation were used to affect a change in response bias, and changes in decision-making behavior were quantified using signal detection theory. Results Response bias became relatively more liberal during both positive and negative motivated trials compared to neutral trials. For both motivational conditions, the larger the liberal shift in bias, the greater the left inferior frontal gyrus (IFG) activity. There was no relationship between individuals' belief that they used a different strategy and their actual change in response bias. Conclusions The present findings suggest that the left IFG plays a role in adjusting response bias across different decision environments. This suggests a potential role for the left IFG in flexible decision-making.

description: This article proposes a new general approach in short-term water demand forecasting based on a two-stage learning process that couples time-series clustering with gene expression programming (GEP). The approach was tested on the real life water demand data of the city of Milan, in Italy. Moreover, multi-scale modeling using a series of head-time was deployed to investigate the optimum temporal resolution under study. Multi-scale modeling was performed based on rearranging hourly based patterns of water demand into 3, 6, 12, and 24 h lead times. Results showed that GEP should receive more attention among the emerging nonlinear modelling techniques if coupled with unsupervised learning algorithms in detailed spherical k-means.

description: This habilitation thesis addresses the functions of different members of the Ras superfamily of small GTPases and their regulators. Particular attention is paid to the signaling functions of TC21, a Ras subfamily member, during cellular transformation and to the roles of a specific regulator of Rho family GTPases, NOMA-GAP/ARHGAP33, during the formation of the mammalian neocortex.
Ultra-high spatial resolution diagnostics of femtosecond laser radiation-induced modification morphology in glasses for the fabrication of microfluidic and microphotonic components

description: The light intensity in a focused femtosecond laser pulse can be high enough to initiate non-linear absorption of the radiation in otherwise transparent dielectric media. The highly localized energy deposition into the material results in permanent changes in its chemical and physical properties which can be used in the fabrication of various photonic and microfluidic devices. In this thesis we study the morphology and optical properties of the modification induced by focused femtosecond laser radiation inside fused silica and other inorganic glasses. The characterization of the modified regions is performed using a microreflection refractometry technique and the ultra-high spatial resolution technique of weak selective chemical etching followed by atomic force microscopy (AFM) and scanning electron microscopy (SEM). We demonstrate that the sample irradiation conditions strongly affect the modification morphology. Specifically, for a tight focusing geometry we identify the pulse duration-pulse energy parameter space where three distinct regimes of modification can be achieved. We also address the effects of optical aberrations on the shape, position and the intensity threshold values of the femtosecond laser induced modification. We use the combination of femtosecond laser dielectric modification and selective chemical etching to fabricate high-quality microchannels in fused silica glass. We show a dramatic dependence of the etch rate on the laser polarization and demonstrate that the high differential etch rate inside the modified regions is determined by the presence of polarization-dependent self-ordered periodic nanocracks or disordered nanoporous structures. These nanostructures are much smaller than the wavelength of the femtosecond radiation used for their formation and are the smallest objects ever created by light inside dielectric materials. Exciting potential applications of the nanostructures will be discussed.

description: How do queer activists in Berlin construct a globally conceived LGBTQ solidarity and movement, despite disagreements over German and American queer history, the future of such a movement, who it serves, and how best to achieve those ends? This dissertation builds on research in queer studies and anthropology which explores the politics of globalization and temporality in queer organizing. Based on a year of ethnographic fieldwork at LGBTQ organizations in Berlin, Germany, each chapter focuses on different kinds of fierce and deeply held debates present among queer activists working to organize around the fiftieth anniversary of the Stonewall Riots, an event sometimes understood to be the starting point for a global period of midcentury gay liberation. Rather than being necessarily divisive or demotivating, I argue that the transnational and temporal tensions that emerge from organizing a movement around these debates are generative, producing new kinds of identity and solidarity which can galvanize renewed commitment to a globally imagined concept of queer justice. I propose Spannung as a metaphor to encapsulate how anthropological concepts for understanding transnational tensions, like “friction” (Tsing 2005) and “dubbing” (Boellstorff 2003), are also embedded within subjective experiences of time. By attending to the way that transnational tensions become temporal and vice versa, I show how organizing across difference entails fraught debates over global politics, generation, collective memory, and futurity, but in the end can result in a robust coalitional commitment to a broadly conceived transnational solidarity.
