A converse to the Grace--Walsh--Szeg\H{o} theorem

We prove that the symmetrizer of a permutation group preserves stability of a polynomial if and only if the group is orbit homogeneous. A consequence is that the hypothesis of permutation invariance in the Grace-Walsh-Szeg\H{o} Coincidence Theorem cannot be relaxed. In the process we obtain a new characterization of the \emph{Grace-like polynomials} introduced by D. Ruelle, and prove that the class of such polynomials can be endowed with a natural multiplication.Comment: 7 page

Some Factors in the Development of an Artist

Painting, an individual, independent activity, grows out of the artist&rsquo;s awareness of his environment, and out of his innate capacity to be aware. The artist has some special ability for expressing uniquely, his emotional reaction to life. As a teacher, I try to understand the artist as an individual, developing his expression out of factors both explicable and inexplicable. &nbsp; This paper is an attempt on my part to understand some of the factors in the development of an artist. They are, the art impulse, the aim of the artist, the tendencies in all creative expression, and the influences of our immediate culture on the artists of today, &nbsp; The material in this paper is the result of my thinking about a number of articles, essays, and books that I have read on the psychology of art, on art education and esthetics, and on other topics related to my subject. &nbsp; No solution to a problem is given here. Rather a number of problems have come out of my reading. One that I wish to investigate further is the associative value of subject in painting.</p

Various Layers in Social Psychology

Understanding humans through social influence is always needed. Through an analysis of specific topics of social psychology, a bridge between issues can be created. This research aims to understand the various layers in social psychology using secondary data. The methodology used in this study is qualitative research, particularly literature review. The subject of this study is some literatures in databases, and other scholarly articles to use as supporting evidence for this work about the study of social psychology. The results provide understanding of layers on social psychology including how individuals interact and function in the day-to-day lives. Human can learn how to better recognize the information process happening in their brains and how to manipulate it in different social situations. The depth of how human relate to each other, and their surroundings is seen through social psychology's "social" aspect. Individuals thoughts, feelings, and behaviors are unique and influenced by social norms' real or imagined presence. This study has theoretical implication on how social psychology has layers to explain how human interact in social context.   Pemahaman tentang manusia melalui pengaruh sosial selalu dibutuhkan. Melalui analisis topik-topik tertentu psikologi sosial, jembatan antar permasalahan dapat diciptakan. Penelitian ini bertujuan untuk memahami berbagai lapisan dalam psikologi sosial dengan menggunakan data sekunder. Metodologi yang digunakan dalam penelitian ini adalah penelitian kualitatif khususnya tinjauan pustaka. Subyek penelitian ini adalah beberapa literatur dalam database, dan artikel ilmiah lainnya yang digunakan sebagai bukti pendukung karya tentang studi psikologi sosial ini. Hasilnya memberikan pemahaman tentang lapisan psikologi sosial termasuk bagaimana individu berinteraksi dan berfungsi dalam kehidupan sehari-hari. Manusia dapat belajar bagaimana mengenali dengan lebih baik proses informasi yang terjadi di otaknya dan bagaimana memanipulasinya dalam berbagai situasi sosial. Kedalaman hubungan manusia satu sama lain, dan lingkungannya dilihat melalui aspek “sosial” psikologi sosial. Pikiran, perasaan, dan perilaku individu bersifat unik dan dipengaruhi oleh kehadiran norma-norma sosial yang nyata atau yang dibayangkan. Kajian ini mempunyai implikasi teoritis mengenai bagaimana psikologi sosial mempunyai lapisan-lapisan untuk menjelaskan bagaimana manusia berinteraksi dalam konteks sosial

Electric Vehicle Art Car

The goal of this project is to design and create a prototype for an electric vehicle platform that can be used as the base of an art car for the Burning Man event. In accordance with the environmental principles of Burning Man and our sponsor organizations, we will pursue sustainability in design and construction of this platform. This platform will serve as a way for event participants to interact with art and function as a way to transport people. As an additional bonus, this platform will set the standard for sustainability for the future of art cars. During this past semester, we conducted thorough research into the feasibility of electric vehicle platforms and explored many possible options. We concluded that the most realistic way to achieve this electric vehicle platform was to build the system entirely from scratch. After this decision, we examined various subsystems necessary for the functionality of the vehicle. At the conclusion of this semester, we were able to test and create a critical function prototype of the steering system. During the next semester, we hope to test and build more prototype subsystems of the drivetrain, the frame, and power storage. By the end of the semester, we hope to deliver a fully-functional model of the art car platform. After completion of these goals, the designs and model will be saved so the project can be expanded upon by another party, most likely ArtBuilds or another senior capstone engineering team

Fluoroquinolone versus nonfluoroquinolone treatment of bloodstream infections caused by chromosomally mediated ampc‐producing enterobacteriaceae

Objectives: Chromosomally mediated AmpC-producing Enterobacteriaceae (CAE) display high susceptibility to fluoroquinolones; minimal clinical data exist supporting comparative clinical outcomes. The objective of this study was to compare treatment outcomes between fluoroquinolone and nonfluoroquinolone definitive therapy of bloodstream infections caused by CAE. Methods: This retrospective cohort assessed adult patients with positive blood cultures for CAE that received inpatient treatment for 48 hours. The primary outcome was difference in clinical failure between patients who received fluoroquinolone (FQ) versus non‐FQ treatment. Secondary endpoints included microbiological cure, infection‐related length of stay, 90‐day readmission, and all‐cause inpatient mortality. Results: 56 patients were included in the study (31 (55%) received a FQ as definitive therapy; 25 (45%) received non‐FQ). All non‐FQ patients received a beta‐lactam (BL). Clinical failure occurred in 10 (18%) patients, with 4 (13%) in the FQ group and 6 (24%) in the BL group (p = 0.315). Microbiological cure occurred in 55 (98%) patients. Median infection‐related length of stay was 10 (6–20) days, with a significantly longer stay occurring in the BL group (p = 0.002). There was no statistical difference in 90‐day readmissions between groups (7% FQ vs. 17% BL; p = 0.387); one patient expired. Conclusion: These results suggest that fluoroquinolones do not adversely impact clinical outcomes in patients with CAE. When alternatives to beta‐lactam therapy are needed, fluoroquinolones may provide an effective option

Polynomials with the half-plane property and matroid theory

A polynomial f is said to have the half-plane property if there is an open half-plane H, whose boundary contains the origin, such that f is non-zero whenever all the variables are in H. This paper answers several open questions regarding multivariate polynomials with the half-plane property and matroid theory. * We prove that the support of a multivariate polynomial with the half-plane property is a jump system. This answers an open question posed by Choe, Oxley, Sokal and Wagner and generalizes their recent result claiming that the same is true whenever the polynomial is also homogeneous. * We characterize multivariate multi-affine polynomial with real coefficients that have the half-plane property (with respect to the upper half-plane) in terms of inequalities. This is used to answer two open questions posed by Choe and Wagner regarding strongly Rayleigh matroids. * We prove that the Fano matroid is not the support of a polynomial with the half-plane property. This is the first instance of a matroid which does not appear as the support of a polynomial with the half-plane property and answers a question posed by Choe et al. We also discuss further directions and open problems.Comment: 17 pages. To appear in Adv. Mat

Evolution of the eyes of vipers with and without infrared-sensing pit organs

We examined lens and brille transmittance, photoreceptors, visual pigments, and visual opsin gene sequences of viperid snakes with and without infrared-sensing pit organs. Ocular media transmittance is high in both groups. Contrary to previous reports, small as well as large single cones occur in pit vipers. Non-pit vipers differ from pit vipers in having a twotiered retina, but few taxa have been examined for this poorly understood feature. All vipers sampled express rh1, sws1 and lws visual opsin genes. Opsin spectral tuning varies but not in accordance with the presence/absence of pit organs, and not always as predicted from gene sequences. The visual opsin genes were generally under purifying selection, with positive selection at spectral tuning amino acids in RH1 and SWS1 opsins, and at retinal pocket stabilization sites in RH1 or LWS (and without substantial differences between pit and nonpit vipers). Lack of evidence for sensory trade-off between viperid eyes (in the aspects examined) and pit organs might be explained by the high degree of neural integration of vision and infrared detection; the latter representing an elaboration of an existing sense with addition of a novel sense organ, rather than involving the evolution of a wholly novel sensory system

The Peterborough Exemplar: a protocol to evaluate the impact and implementation of a new patient-centred, system-wide community mental healthcare model in England.

BACKGROUND: Community mental healthcare has significantly grown since de-institutionalization. Despite progress, service fragmentation and gaps in service provision remain key barriers to effective community care in England. Recent mental healthcare policies highlighted the need to transform service provision by developing patient-centred, joined-up community mental healthcare. In response to policy guidance, a system-wide community mental healthcare model was developed in Peterborough (England). The "Peterborough Exemplar" is based on two main pillars: (1) the creation of knowledge exchange pathways to strengthen interorganizational relationships, and (2) the development of new, accessible community services addressing existing service gaps. This paper presents the protocol developed to evaluate the Peterborough Exemplar. METHODS: A quasi-experimental design with an intervention group and a nonequivalent comparator group has been developed to compare service provision provided in Peterborough pre- and post-intervention with services provided in Fenland, a neighbouring area where service users access usual care. Two evaluation methods will be employed to compare service provision between the two groups: (1) outcome measures completed by service users and carers will be analysed to assess quality of life and service satisfaction, and (2) service activity data will be analysed to assess service usage. In addition, qualitative interviews will be conducted with staff members of participating organizations to explore the implementation of the Exemplar in Peterborough and evaluate knowledge exchange processes among local service providers. A matched control approach will be used to compare outcome measures between the two areas. Descriptive and inferential statistics, including chi-square tests, will be used to analyse service activity data and examine differences between the two areas. A thematic analysis will be adopted to analyse qualitative data. DISCUSSION: Outcomes of the evaluation will contribute to understanding the contribution of the Peterborough Exemplar on mental health service provision locally. Evaluation findings and intermediate reporting will be shared with organizations involved in the implementation of the Peterborough Exemplar and with local decision-makers to inform the Exemplar delivery. As the Peterborough Exemplar is an Early Implementer (EI) site funded by NHS England, findings will be shared with policy-makers to inform national policy on community mental healthcare and integrated care
