RSVP-TE Extensions to Provide Guarantee of Service to MPLS 1

Abstract. Independent Quality of Service (QoS) models need to be set up in IP and ATM integration and they are difficult to coordinate. This gap is bridged when MultiProtocol Label Switching (MPLS) is used for this purpose. We propose Guarantee of Service (GoS) to improve performance of privileged flows in congested MPLS networks. We first discuss the GoS requirements for the use in conjunction with MPLS. Then we propose a minimum set of extensions to RSVP-TE that allow signaling of GoS information across the MPLS domain

Over-the-Counter Leadership: The Teacher's Impact on Life Formation

El presente documento refleja desde la narrativa docente la autenticidad del líder educativo y los diferentes desafíos presentados al momento de ejecutar procesos de formación y aprendizaje. Un análisis de la investigación sobre “Los estilos de liderazgo y su influencia en el desempeño profesional en 50 instituciones Educativas públicas de la Región Andina” el cual demuestra como el maestro cuyo significado del latín traduce “el más mejor” es valorado por sus habilidades innatas obteniendo el reconocimiento de la comunidad educativa y el impacto de su gestión conllevan a la búsqueda de la mejora continua. El objetivo general del presente artículo es generar de manera reflexiva un análisis respecto a la valoración del maestro en la academia y la influencia de su liderazgo para lograr el saber -saber, saber hacer y la enseñanza del saber ser una formación para la vida. Como objetivo específico se busca identificar la influencia de los estilos de liderazgo en el desempeño profesional del maestro y la simbiosis con la teoría de las inteligencias múltiples de Gardner. Para lograr un mejor resultado en calidad educativa el autor Duffy (2000) afirma el líder educativo debe preocuparse por llevar a cabo practicas educativas con responsabilidad las cuales aporten a los objetivos organizacionales de la institución. La metodología implementada para esta investigación es de corte descriptivo hermenéutico con un enfoque cualitativo, la población relacionada hace referencia a docentes y directivos a los cuales se aplicó la entrevista semiestructurada como instrumento de recolección de información que permitió dar respuesta a las diferentes categorías planteadas. Como resultado del estudio se destaca el nivel de influencia y carisma del líder en el contexto académico a través del análisis de la teoría de las inteligencias múltiples. Una reflexión del verdadero liderazgo sin receta y el impacto en la formación para la vida de los educandos.This document reflects from the teaching narrative the authenticity of the educational leader and the different challenges presented when executing training and learning processes. An analysis of the research on "Leadership styles and their influence on professional performance in 50 public educational institutions in the Andean Region" which demonstrates how the teacher whose Latin meaning translates "the best" is valued for his innate abilities obtaining the recognition of the educational community and the impact of his management lead to the search for continuous improvement. The general objective of this article is to generate in a reflective way an analysis regarding the valuation of the teacher in the academy and the influence of his leadership to achieve knowledge -knowledge, know-how and the teaching of knowledge to be a formation for life. As a specific objective, it seeks to identify the influence of leadership styles on the professional performance of the teacher and the symbiosis with Gardner's theory of multiple intelligences. To achieve a better result in educational quality the author Duffy (2000) states the educational leader must worry about carrying out educational practices with responsibility which contribute to the organizational objectives of the institution. The methodology implemented for this research is descriptive hermeneutic with a qualitative approach, the related population refers to teachers and administrators to whom the semi-structured interview was applied as an instrument for collecting information that allowed responding to the different categories raised. As a result of the study, the level of influence and charisma of the leader in the academic context is highlighted through the analysis of the theory of multiple intelligences. A reflection of true leadership without prescription and the impact on the life formation of learners

Teaching DBT Skills to DACA Recipients and their Families: Findings from an ECHO Program

Deferred Action for Childhood Arrivals (DACA) offers temporary administrative relief from deportation for undocumented immigrant adolescents and young adults who were brought as children to the United States. Accordingly, DACA has contributed to creating a different landscape of opportunities for this group. However, DACA has been and continues to be highly contested in the national political climate. Threats to DACA give rise to considerable anxiety, fear, and distress among its recipients, who face significant barriers to accessing mental health care services. Thus, a group of psychologists partnered with a leading immigrant rights advocacy organization and formed a reciprocal collaboration to understand and meet the mental health needs of undocumented communities. A major focus of the collaboration is to foster learning and support members of the immigrant community in contributing to their own well-being. The collaborative developed and delivered a stand-alone web-based mental health education session to DACA recipients and their families and practitioners serving this population. The session presented the use of dialectical behavioral therapy skills, three emotion regulation and four distress tolerance skills, as a strength-based approach to managing painful emotions and distress. Session content was adapted to include culturally informed examples for each skill. Quantitative and qualitative findings show that those who participated in the web-based program benefited from the education received. Findings also underscored participants’ need for learning culturally sensitive coping strategies for managing stress. We provide recommendations on the delivery of culturally congruent healing interventions for immigrants with a focus on enhancing access among immigrant communities

Permission from IEEE must be obtained for all other uses, in any current or future media, including reprinting/republishing this material for advertising or promotional purposes, creating new collective works, for resale or redistribution to servers or lists, or reuse of any copyrighted component of this work in other worksIn this paper, a planar active phased array antenna demonstration with linear polarization (LP) at Ka Band (28-30 GHz) is presented. The proof of concept is carried out to evaluate the possible problems that may arise, to analyze possible calibration stages and to assess the viability of the integration of an active system with a Multi-Channel Beamforming Module (MCBM). To fulfill this task an 8times 8-element planar array arranged in column subarrays of 1times 8 elements for 1D beam steering is proposed. The single element consists of a printed circular patch connected to a microstrip feeding line through metallic vias in a multilayered structure. Both the amplitude and phase distributions are performed by a commercial integrated circuit (IC) designed for transmission purposes, from the common port to each of the 8 output ports. Thus, an evaluation of the IC performance is also included within this work. Despite the inherent amplitude and phase feeding errors of the IC, the beam-steering accuracy of the system is reasonable. A nice correspondence between the simulated and measured 8times 8-element array beam steering directions is obtained, with errors below 1° in the steering of the beamThis work was supported in part by the Spanish Government, Ministry of Economy, National Program of Research, Development and Innovation through the Project FUTURE RADIO ’’Radio systems and technologies for high capacity terrestrial and satellite communications in an hyperconnected world’’ under Grant TEC2017-85529-C3-1-R, and in part by the Project JETSTREAM ’’Desarrollo de una antena banda KA embarcada para la prestación de servicios de acceso a Internet por satélite en aviación comercial’’ in collaboration with TELNET Redes Inteligentes S.A. under Grant RTC-2015-3495-

Sex-Dimorphic Behavioral Alterations and Altered Neurogenesis in U12 Intron Splicing-Defective Zrsr1 Mutant Mice

Mutant mice with respect to the splicing factor Zrsr1 present altered spermatogenesis and infertility. To investigate whether Zrsr1 is involved in the homeostatic control that the hypothalamus exerts over reproductive functions, we first analyzed both differential gene and isoform expression and alternative splicing alterations in Zrsr1 mutant (Zrsr1mu) hypothalamus; second, we analyzed the spontaneous and social behavior of Zrsr1mu mice; and third, we analyzed adult cell proliferation and survival in the Zrsr1mu hypothalamus. The Zrsr1mu hypothalamus showed altered expression of genes and isoforms related to the glutathione metabolic process, synaptonemal complex assembly, mRNA transport, and altered splicing events involving the enrichment of U12-type intron retention (IR). Furthermore, increased IR in U12-containing genes related with the prolactin, progesterone, and gonadotropin-releasing hormone (GnRH) reproductive signaling pathway was observed. This was associated with a hyperactive phenotype in both males and females, with an anxious phenotype in females, and with increased social interaction in males, instead of the classical aggressive behavior. In addition, Zrsr1mu females but not males exhibited reduced cell proliferation in both the hypothalamus and the subventricular zone. Overall, these results suggest that Zrsr1 expression and function are relevant to organization of the hypothalamic cell network controlling behavior

Recommendations for SARS-CoV- 2/ COVID-19 testing: a scoping review of current guidance

Background Testing used in screening, diagnosis and follow-up of COVID-19 has been a subject of debate. Several organisations have developed formal advice about testing for COVID-19 to assist in the control of the disease. We collated, delineated and appraised current worldwide recommendations about the role and applications of tests to control SARS-CoV- 2/COVID-19. Methods We searched for documents providing recommendations for COVID-19 testing in PubMed, EMBASE, LILACS, the Coronavirus Open Access Project living evidence database and relevant websites such as TRIP database, ECRI Guidelines Trust, the GIN database, from inception to 21 September 2020. Two reviewers applied the eligibility criteria to potentially relevant citations without language or geographical restrictions. We extracted data in duplicate, including assessment of methodological quality using the Appraisal of Guidelines for Research and Evaluation-II tool. Results We included 47 relevant documents and 327 recommendations about testing. Regarding the quality of the documents, we found that the domains with the lowest scores were ‘Editorial independence’ (Median=4%) and ‘Applicability’ (Median=6%). Only six documents obtained at least 50% score for the ‘Rigour of development’ domain. An important number of recommendations focused on the diagnosis of suspected cases (48%) and deisolation measures (11%). The most frequently recommended test was the reverse transcription-PCR (RT-PCR) assay (87 recommendations) and the chest CT (38 recommendations). There were 22 areas of agreement among guidance developers, including the use of RT-PCR for SARS-Cov- 2 confirmation, the limited role of bronchoscopy, the use chest CT and chest X-rays for grading severity and the co-assessment for other respiratory pathogens. Conclusion This first scoping review of recommendations for COVID-19 testing showed many limitations in the methodological quality of included guidance documents that could affect the confidence of clinicians in their implementation. Future guidance documents should incorporate a minimum set of key methodological characteristics to enhance their applicability for decision making.Instituto de Salud Carlos III 2017/CD17/00219European Social Fund 2014-2020, 'Investing in your future'Spanish Governmen
