RENDIMIENTO ACADÉMICO DE ESTUDIANTES UNIVERSITARIOS EN LA UNSJ. ESTUDIO DE CASOS”
No full textEl objetivo de esta presentación es hacer un análisis comparativo de las características de los alumnos ingresantes de dos unidades académicas de la UNSJ, con marcadas diferencias en el rendimiento académico entre ambas unidades. El análisis comparativo se centra en los alumnos de las carreras de profesorados y licenciaturas de la Facultad de Filosofía, Humanidades y Artes (FFHA) y de ingenierías de la propia Facultad de Ingenierías (FI). Si bien el análisis focaliza en aspectos objetivos (condiciones materiales y simbólicas) y aspectos subjetivos (representaciones que los alumnos tienen de sí, del saber del que se ocupan, del campo profesional) y sus articulaciones en las prácticas institucionales y en el espacio socio-político más amplio, para esta presentación sólo abordamos información relativa al rendimiento académico de los alumnos de primer año e información relativa al patrimonio económico familiar, situación laboral, becas de ayuda económica. Para relevar la información nos hemos valido de encuestas y entrevistas. También hacemos una caracterización de las carreras seleccionadas según el estado y la dinámica de los campos desde una perspectiva sincrónica y diacrónica, teniendo en cuenta sus articulaciones en el espacio social. Los aportes de la pedagogía crítica y de la sociología de P. Bourdieu, representan nuestros referentes teórico-metodológicos principales
Time-dependent angular analysis of the decay Bs -> J/psi phi and extraction of Delta Gamma_s and the CP-violating weak phase phi_s by ATLAS
No full textA measurement of Bs J/psi phi decay parameters, including the CP-violating weak phase phi_s and the decay width difference Delta Gamma_s is reported, using 4.9 fb-1 of integrated luminosity collected in 2011 by the ATLAS detector from LHC pp collisions at a centre- of-mass energy sqrt(s) = 7 TeV. The mean decay width Gamma_s and the transversity amplitudes |A0(0)|^2 and |A||(0)|^2 are also measured. The values reported for these parameters are: phi_s = 0.22 \pm 0.41 (stat.) \pm 0.10 (syst.) rad Delta Gamma_s = 0.053 \pm 0.021 (stat.) \pm 0.010 (syst.) ps-1 Gamma_s = 0.677 \pm 0.007 (stat.) \pm 0.004 (syst.) ps-1 |A0(0)|^2 = 0.528 \pm 0.006 (stat.) \pm 0.009 (syst.) |A||(0)|^2 = 0.220 \pm 0.008 (stat.) \pm 0.007 (syst.) where the values quoted for phi_s and Delta Gamma_s correspond to the solution compatible with the external measurements to which the strong phase delta perpendicular is constrained and where Delta Gamma_s is constrained to be positive. The fraction of S-wave KK or f0 contamination through the decays Bs -> J/psi K+K-(f0) is measured as well and is found to be consistent with zero. Results for phi_s and Delta Gamma_s are also presented as 68%, 90% and 95% likelihood contours, which show agreement with Standard Model expectations
Correlation Study between Laboratory Performance and Internship Grades of BS Information Technology and BS Computer Science Students in Lemery Colleges S.Y. 2021-2022
No full textAbstract: The computer lab is very important to the student’s education. Every institution or university should have this as a key resource, especially for tech-related programs like BS Information Technology and BS Computer Science. The purpose of the study is to evaluate the connection between students with BSs in information technology and computer science's laboratory performance and internship grades. The main goal of the study is whether a student's success in the lab during their first year of college has an impact on how well they do in their practicum or internship. The descriptive-correlational study approach was used to demonstrate the laboratory performance of the SY 2021–2022 BSIT and BSCS graduating class. Performance indicators (PI) and the marks they got from the firms during their internships were used to demonstrate this performance. 35 graduates of the BS in information technology and 16 graduates of the BS in computer science from the academic year 2021–2022 are taking part in this study. It was concluded that there is a strong correlation between laboratory performance and academic internships under corporate supervision. These results contribute to a better significance of performance indicator assessment in laboratory procedures. The second goal is to raise the standards of the quality indicators used to evaluate and track students' computer lab performance. The research recommended integrating academic success and student output at work to create more meaningful data for quality improvement.

Publisher Copyright: © 2007 - 2019 Frontiers Media S.A. All Rights Reserved.NorA is the best studied efflux system of Staphylococcus aureus and therefore frequently used as a model for investigating efflux-mediated resistance in this pathogen. NorA activity is associated with resistance to fluoroquinolones, several antiseptics and disinfectants and several reports have pointed out the role of efflux systems, including NorA, as a first-line response to antimicrobials in S. aureus. Genetic diversity studies of the gene norA have described three alleles; norAI, norAII and norAIII. However, the epidemiology of these alleles and their impact on NorA activity remains unclear. Additionally, increasing studies do not account for norA variability when establishing relations between resistance phenotypes and norA presence or reported absence, which actually corresponds, as we now demonstrate, to different norA alleles. In the present study we assessed the variability of the norA gene present in the genome of over 1,000 S. aureus isolates, corresponding to 112 S. aureus strains with whole genome sequences publicly available; 917 MRSA strains sourced from a London-based study and nine MRSA isolates collected in a major Hospital in Lisbon, Portugal. Our analyses show that norA is part of the core genome of S. aureus. It also suggests that occurrence of norA variants reflects the population structure of this major pathogen. Overall, this work highlights the ubiquitous nature of norA in S. aureus which must be taken into account when studying the role played by this important determinant on S. aureus resistance to antimicrobials.publishersversionpublishe
Análisis de supervivencia, desarrollo y fotosíntesis de tres especies forestales en plantaciones jóvenes establecidas en el bosque seco tropical (bs-t), Antioquia, Colombia
No full textResumen: el bosque seco tropical es uno de los ecosistemas más afectados en el mundo por el desarrollo de actividades antrópicas, lo que hace necesario avanzar en estudios referentes a su dinámica, recuperación y restauración; así como, en la identificación de las especies características de esta formación vegetal, que puedan ser utilizadas como un recurso importante para dar inicio a procesos de restauración y reforestación comercial. Con el objetivo de determinar la supervivencia, desarrollo y comportamiento fotosintético de tres especies forestales en edades tempranas, se implementó un ensayo bajo condiciones de campo con especies propias de bs-T: Cedrela odorata (cedro rojo), Pachira quinata (ceiba tolúa) y Ochroma pyramidale (balso). Este estudio inició en el año 2011 y durante un periodo de 14 meses se hizo seguimiento a la altura total (H) y al diámetro a la base (DBC) de los árboles; se realizaron dos cosechas vegetales para la medición del peso seco y, en el año 2012, se hizo un seguimiento más específico que consistió en evaluar el funcionamiento fotosintético y su influencia en el desarrollo de las especies en tres periodos pluviométricos contrastantes, midiendo las variables: Temperatura ambiente (Tamb), Temperatura de la hoja (thoja), Radiación Fotosintéticamente Activa (PAR), Conductancia Estomática (gs), Carbono intercelular (Cint), Fotosíntesis Neta (PN), transpiración (trans), Uso eficiente del agua (WUE) y el uso eficiente de la luz (LUE). Estas mediciones se realizaron entre las 8:00 y 17:00 horas, seleccionando una hoja sana en cada individuo, utilizando un sistema portátil de fotosíntesis (TPS – 2 PPSYSTEMS). Se aplicaron histogramas para identificar la tendencia diamétrica y altimétrica de las especies, así como, un análisis de varianza, mediante el uso de modelos mixtos, para identificar el comportamiento de las variables entre especies (efectos principales de las especies), entre periodos pluviométricos (efectos principales de los periodos pluviométricos) y la combinación periodos pluviométricos y especies (efectos simples de la interacción). Se encontraron diferencias significativas (p- valor 0.05) en la interacción en las variables altura y diámetro (H y DBC) y en la variable fotosintética PN; las variables gs y trans fueron significativas en las especies y en los periodos pluviométricos; Cint fue significativa, solo, en los periodos pluviométricos. En WUE y LUE no hubo diferencias significativas. Cada una de las especies mostró un desempeño diferente ante las condiciones climáticas, lo que se reflejó en su supervivencia, crecimiento y desarrolloMaestrí

Jetting, In-Nozzle Meniscus Motion and Nozzle-Plate Flooding in An Industrial Drop-on-Demand Print Head
No full textThe state of the ink film at and near the nozzles of a drop-ondemand(DoD) print head during jetting has a direct impact on
printing performance and reliability. We have developed highspeed imaging apparatus and analytical techniques to investigate
the ink film dynamics on an industrial print head nozzle-plate in real-time. In addition to a direct correlation between the jet
emergence velocity and drive voltage, drive-dependent variations in the oscillation of the ink meniscus in adjacent nozzles were also observed. Using a ray-tracing model to analyze the meniscus shape, the meniscus oscillations for both printing and nonprinting nozzles were found to be complex and involve elements such as pre-oscillation and high-order surface waves. The flooding of non-firing nozzles, deliberately caused by the application of maximum drive voltage to a neighboring nozzle, has been recorded and analyzed dynamically. The build-up of fluid in an annulus around the nozzle (flooding rate) has been characterized and compared with models for the net ink flow
through the nozzle

Is BS 7799 worth the effort?
No full textNORSK:
Denne masteroppgaven fokuserer på hvorvidt organisasjoner som har sertifisert sitt styringssystem for
informasjonssikkerhet etter BS 7799, oppnår en bedre evne til å forebygge, detektere og reagere på
sikkerhetsbrudd slik at konsekvensene ved sikkerhetsbrudd reduseres. Masteroppgaven vil også
utforske om det er en forskjell på organisasjoner som benytter BS 7799 på en uformell måte kontra
organisasjoner som ikke benytter standarden.
I disse dager er det en utfordring for informasjonssamfunnet at informasjonssikkerhet et styrt og
håndtert på mange forskjellige måter. I dag, og i fremtiden, kan det være vitalt å kunne håndtere
informasjonssikkerheten iht. et felles sett med prinsipper, uavhengig av organisasjon.
Vi har gjennomført en undersøkelse i form av en spørreundersøkelse. Spørreundersøkelsen ble
distribuert til sikkerhetssjefer eller stabspersonell innen informasjonssikkerhet i 40 norsk virksomheter
hvor vi forventet at et styringssystem for informasjonssikkerhet var implementert. Åtte av
virksomhetene var sertifisert etter BS 7799-2. Vi hadde også klare forventninger til at
informasjonssikkerhet var et viktig tema i de andre virksomhetene.
I spørreundersøkelsen spurte vi organisasjonene om følgende:
-konsekvensene som har rammet organisasjonen fra 1999 til 2004, estimert som økonomiske
tap
- hvordan brudd på informasjonssikkerhet er håndtert i organisasjonen og mulighetene for oss
til å få tilgang til de statistiske data angående brudd på sikkerheten
- hvilke deler av styringssystemer som er implementert og hvordan det er implementert
Angående spørsmålet om styringssystem for informasjonssikkerhet spurte vi om de vitale delene som
burde vært implementert i alle virksomheter med et visst behov for å beskytte organisasjonens verdier.
Svarene angående konsekvenser og statistiske data angående brudd på sikkerheten var for få til å
sammenligne sertifiserte organisasjoner, organisasjoner som benytter standarden uformelt og de
organisasjoner som ikke benytter en standard.
Resten av spørreskjemaet fokuserte på de vitale delene av et styringssystem for
informasjonssikkerhet. Svarene på disse spørsmålene gjorde det mulig å estimere modenhetsnivået på
organisasjonens styringssystem for informasjonssikkerhet. Modenhetsnivået på styringssystemet for
informasjonssikkerhet kan ansees som et speilbilde av nivået på informasjonssikkerheten i
organisasjonene.
Konklusjonene i denne masteroppgaven er at sertifiserte organisasjoner har et høyere modenhetsnivå
enn organisasjoner som har valgt å benytte standarden til å implementere et uformelt styringssystem
for informasjonssikkerhet. De organisasjoner som har implementert et uformelt styringssystem har et
høyere modenhetsnivå enn de organisasjonene som ikke har implementert noen form for
styringssystem
Search for LFV in Bs Decays
No full textThe flavor changing neutral current process is forbidden at tree level in the Standard Model (SM) and can only proceed via suppressed loop level diagrams.In the recent years, some deviation in the experimental measurements of Lepton Flavor Universality in B decays (i.e., b→ sℓℓ and b→ cℓν ) from the SM prediction and some theoretical models hint that there are lepton flavor violating interactions.Therefore, observation of the Lepton Flavor Violation (LFV) in B decays would be a clear signal of physics beyond the SM.We report herein the sensitivity study of Bs→ ℓτ(ℓ= μ, e) at Belle. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd
