A Review of Prevention, Early Recognition, and Directed Therapy of Sepsis

Description

Sepsis is a global health problem, and millions of people die annually from sepsis around the world (Centers for Disease Control and Prevention, 2018). The purpose of this literature review

Sepsis is a global health problem, and millions of people die annually from sepsis around the world (Centers for Disease Control and Prevention, 2018). The purpose of this literature review is to discuss the prevention, recognition, and treatment of sepsis as well as the need for more public health education to raise awareness of the significant burden of sepsis. It is difficult to recognize because there are several nonspecific symptoms, and there is not a comprehensive diagnostic tool. Diagnosis is based on evidence of infection, organ dysfunction, and clinical judgment (Fay et al., 2020). The definition of sepsis has evolved over the last three decades, though the most recent update is not widely accepted by all healthcare systems. There remains debate about treatment practices as well, including the following: whether one or multiple antibiotics should be used, which type of fluids should be used for rapid resuscitation, and the number of fluids that should be given to the patient. However, evidence agrees that treatment should be started within the first hour of symptom onset for the best chance of survival (Gyawali, Ramakrishna, & Dhamoon, 2019). Despite the significant burden that sepsis places on families, healthcare team members, and hospitals, there is not enough public awareness of the issue (Jabaley et al., 2018). There should be a greater push for public education using technology, social media, and mass media campaigns to increase awareness and prevention of infection.

Curation and Hegemony

Description

Recognition of sovereignty provides the means by which states have their independence and sovereignty formalized. In cases of secessionist conflict, the decision to grant or withhold recognition of a new state is forced upon the international system, unlike cases that deal with decolonization or internationally imposed partition. Recognition therefore provides a means by which members of the international system can curate the potential international membership from a set of new secessionist states. A central feature of this curatorial function is that it does not proceed evenly, multilaterally, or simultaneously across all cases. Instead, curation proceeds along hegemonic lines in a Gramscian sense: recognition is granted by great powers that lead particular hegemonic systems in an effort to expand their images of social order to new states. These fractures are expressed clearly in cases of split or contested recognition. The paper proceeds from a discussion of secession since the end of the Cold War, then assesses the input of contemporary literature, and ends with the suggestion of curation as a new means to understand the dynamics of international recognition.

Virtuosity Through the Ages: A Sampling of Virtuosic Clarinet Works

Description

This thesis explores virtuosity as it applies to the following five clarinet works: Grand Duo Concertant by Carl Maria von Weber, Solo de Concours by André Messager, Caprice by Anders

This thesis explores virtuosity as it applies to the following five clarinet works: Grand Duo Concertant by Carl Maria von Weber, Solo de Concours by André Messager, Caprice by Anders Koppel, Live Wire by Theresa Martin, and The Bangui Anomaly by Eric Mandat. By detailing the clarinet’s development, including its creation in the early 18th century and key innovations over the next several hundred years, the histories of several key clarinet manufacturers are described to further analyze the innovation of music at the time. This background is necessary to understand the foundation of the clarinet and how virtuosity is tied closely to its mechanical development. Based on this fundamental information, virtuosity is comprised of three pillars: technical proficiency, musicianship, and recognition. In order for a piece or performer to be considered virtuosic, they must exemplify all three pillars. Technical proficiency applies to physically manipulating the instrument, including finger agility, articulation, voicing, dynamic and intonation control, among others. Musicianship further describes personal interpretation within stylistic boundaries, and the ability to implement interpretive judgement. Finally, recognition serves as esteemed acknowledgement from a panel of field critics. Accompanying this paper is a creative performance recording of the five aforementioned clarinet pieces, demonstrating virtuosity through a wide range of musical genres and eras.

Modern audio datasets and machine learning software tools have given researchers a deep understanding into Music Information Retrieval (MIR) applications. In this paper, we investigate the accuracy and viability of using a machine learning based approach to perform music genre recognition using the Free Music Archive (FMA) dataset. We compare the classification accuracy of popular machine learning models, implement various tuning techniques including principal components analysis (PCA), as well as provide an analysis of the effect of feature space noise on classification accuracy.

Emotion recognition through facial expression plays a critical role in communication. Review of studies investigating individuals with traumatic brain injury (TBI) and emotion recognition indicates significantly poorer performance compared to controls. The purpose of the study was to determine the effects of different media presentation on emotion recognition in individuals with TBI, and if results differ depending on severity of TBI. Adults with and without TBI participated in the study and were assessed using the The Awareness of Social Inferences Test: Emotion Evaluation Test (TASIT:EET) and the Facial Expressions of Emotion-Stimuli and Tests (FEEST) The Ekman 60 Faces Test (E-60-FT). Results indicated that individuals with TBI perform significantly more poorly on emotion recognition tasks compared to age and education matched controls. Additionally, emotion recognition abilities greatly differ between mild and severe TBI groups, and TBI participants performed better with the static presentation compared to dynamic presentation.

Application of recognition tunneling in single molecule identification

Single molecule identification is one essential application area of nanotechnology. The application areas including DNA sequencing, peptide sequencing, early disease detection and other industrial applications such as quantitative and quantitative analysis of impurities, etc. The recognition tunneling technique we have developed shows that after functionalization of the probe and substrate of a conventional Scanning Tunneling Microscope with recognition molecules ("tethered molecule-pair" configuration), analyte molecules trapped in the gap that is formed by probe and substrate will bond with the reagent molecules. The stochastic bond formation/breakage fluctuations give insight into the nature of the intermolecular bonding at a single molecule-pair level. The distinct time domain and frequency domain features of tunneling signals were extracted from raw signals of analytes such as amino acids and their enantiomers. The Support Vector Machine (a machine-learning method) was used to do classification and predication based on the signal features generated by analytes, giving over 90% accuracy of separation of up to seven analytes. This opens up a new interface between chemistry and electronics with immediate implications for rapid Peptide/DNA sequencing and molecule identification at single molecule level.

Visual recognition for dynamic scenes

Description

Recognition memory was investigated for naturalistic dynamic scenes. Although visual recognition for static objects and scenes has been investigated previously and found to be extremely robust in terms of fidelity and retention, visual recognition for dynamic scenes has received much less attention. In four experiments, participants view a number of clips from novel films and are then tasked to complete a recognition test containing frames from the previously viewed films and difficult foil frames. Recognition performance is good when foils are taken from other parts of the same film (Experiment 1), but degrades greatly when foils are taken from unseen gaps from within the viewed footage (Experiments 3 and 4). Removing all non-target frames had a serious effect on recognition performance (Experiment 2). Across all experiments, presenting the films as a random series of clips seemed to have no effect on recognition performance. Patterns of accuracy and response latency in Experiments 3 and 4 appear to be a result of a serial-search process. It is concluded that visual representations of dynamic scenes may be stored as units of events, and participant's old
ew judgments of individual frames were better characterized by a cued-recall paradigm than traditional recognition judgments.

DNA sequencing by recognition tunnelling

Single molecules in a tunnel junction can now be interrogated reliably using chemically-functionalized electrodes. Monitoring stochastic bonding fluctuations between a ligand bound to one electrode and its target bound to a second electrode ("tethered molecule-pair" configuration) gives insight into the nature of the intermolecular bonding at a single molecule-pair level, and defines the requirements for reproducible tunneling data. Importantly, at large tunnel gaps, there exists a regime for many molecules in which the tunneling is influenced more by the chemical identity of the molecules than by variability in the molecule-metal contact. Functionalizing a pair of electrodes with recognition reagents (the "free analyte" configuration) can generate a distinct tunneling signal when an analyte molecule is trapped in the gap. This opens up a new interface between chemistry and electronics with immediate implications for rapid sequencing of single DNA molecules.

"Us Here, Them There": The Politics of Recognition in Israel-Palestine

Description

The concept of recognition developed through the 20th century as a form of political legitimation has served a central if problematic role in understanding international politics. On the one hand,

The concept of recognition developed through the 20th century as a form of political legitimation has served a central if problematic role in understanding international politics. On the one hand, recognition aims toward establishing essential collective identities that must be conceived as relatively stable in order to then gain respect, receive political protection, and occupy both physical and discursive space. On the other hand, recognition tacitly accepts a social constructivist view of the subject who can only become whole unto itself – and in turn exercise positive liberty, freedom, or agency – through the implied assent or explicit consent of another. There is an inherent tension between these two understandings of recognition. The attempt to reconcile this tension often manifests itself in forms of symbolic and systemic violence that can turn to corporeal harm. In order to enter into the concept, history, politics and performativity of recognition, I focus on what is often viewed as an exceptionally complex and uniquely controversial case: the Israel-Palestine conflict. Undergoing a discourse analysis of three epistemic communities (i.e., the State/diplomatic network, the Academic/intellectual network, the Military-Security network) and their unique modes of veridiction, I show how each works to construct the notion of ethno-nationalism as a necessary political logic that holds the promise of everything put in its right place: Us here, Them there. All three epistemic communities are read as knowledge/power networks that have substantial effect on political subjects and subjectivities. Influenced by the philosophy of Hegel and Levinas, and supported by the works of Michel Foucault, Wendy Brown, Alphonso Lingis, Jacques Derrida, Patchen Markell, and others, I show the ways in which our current politics of recognition is best read as violence. By tracing three discursive networks of knowledge/power implicated in our modern politics of recognition, I demonstrate forms of symbolic violence waged against the entire complex of the Israel-Palestine conflict in ways that preclude a just resolution based on mutual empathy, acknowledgment, and (re)cogntion.

The self & Basquiat: limitations of pedagogy in the recognition of post-colonial aesthetics

The life of Jean-Michel Basquiat is often misinterpreted in artistic discourse. From a social justice perspective, Basquiat's work is not merely art. Despite the symbolism and subject matter open for analysis, Basquiat articulated the self in relation to nuances of race, socio-economy, and historical scripts based upon real relations and conditions. Of the genre of Neo-Expressionism without a disciplined schooling in art, Jean-Michel is categorized as 'primitive' in style and form, labeled the "first black artist." Beyond the art world's possessive confines and according to post-colonial aesthetics, Jean-Michel articulates the existence of a learning self. With a pedagogical lens, a process of becoming an "artist" deepened Basquiat's expressions of self in relation to a “white” art world, which typically restricted the artist to specific categories and definitional parameters.

While recognition of the "artist" highlights the limitations of 'public' and 'self' in pedagogy, learning of the self through Neo-Expressionism is contingent upon articulating a situated existence among particular "publics," with regard to time and place. Variable dimensions of recognition create a fragmented self with transitional 'stages' and a series of acute shifts re-establish the definitional boundaries of art, definers, and ultimately the self and “Other”. These shifts continuously create new margins of the avant-garde and the self is redefined by art and discourse to sustain capital inflow, thereby replicating the colonial nature of capitalism with regard to communication, material and discovery, and “Other”. The process eschews a realized finality while expression as a relational communication of the situated persona redefines one's identity and demarcates a value of the self.
