EXAMINING EDUCATORS’ PERCEPTIONS AND PREPAREDNESS ON THE NEEDS OF UNDOCUMENTED STUDENTS
This study explored educator perspectives on the needs that undocumented students have and perceived preparedness on supporting students in this population. This study arose from the need to further explore how prepared educators are to address the many barriers that undocumented students face in navigating school and their home lives. Using a mixed-methods research approach, this study gathered educator perceptions through quantitative survey data and qualitative interviews. Survey data used descriptive statistics to analyze demographic data and used statistical correlational analyses between variables to explore the question of educator’s perceptions of undocumented students’ needs and preparedness. Thematic analysis of gathered interview data further informed this exploratory query. A total of 58 K-12 public school teachers across California were surveyed, from which 6 participants were also interviewed. The exploratory results from this study indicated that teachers, on average, held a moderate understanding of undocumented student needs but conveyed having insufficient support and training to address those needs. The findings of this research study contribute to social work practice by providing insight on possible deficiencies in the support systems that exist for individuals of undocumented status and help to demonstrate where school based social workers can work collaboratively with educators to improve services for undocumented students and families

Indexación: Scopus.Funding for this research was provided by: Fondecyt Regular (award No. 1151527); Proyecto REDES ETAPA INICIAL, Convocatoria 2017 (award No. REDI170423); Millennium Institute for Research in Optics (MIRO); Basal USA (award No. 1799).Hexaaquazinc(II) dinitrate 5-(pyridinium-3-yl)tetrazol-1-ide, [Zn(H2 O)6](NO 3)2 ·2C6H5 N 5, crystallizes in the space group P. The asymmetric unit contains one zwitterionic 5-(pyridinium-3-yl)tetrazol-1-ide molecule, one NO3-anion and one half of a [Zn(H2 O)6]2+ cation (symmetry). The pyridinium and tetrazolide rings in the zwitterion are nearly coplanar, with a dihedral angle of 5.4 (2)°. Several O-H..N and N-H..O hydrogen-bonding interactions exist between the [Zn(H2 O)6]2+ cation and the N atoms of the tetrazolide ring, and between the nitrate anions and the N-H groups of the pyridinium ring, respectively, giving rise to a three-dimensional network. The 5-(pyridinium-3-yl)tetrazol-1-ide molecules show parallel-displaced π-π stacking interactions; the centroid-centroid distance between adjacent tetrazolide rings is 3.6298 (6) Å and that between the pyridinium and tetrazolide rings is 3.6120 (5) Å. © 2018 Chi-Duran et al.http://journals.iucr.org/e/issues/2018/09/00/cq2025/index.htm
Does Corporate Control Transactions’ Type and Focus really Create Value? Evidence from an Emerging Market
The failure of corporate-control transactions as strategic-oriented transactions to create significant values for their stockholders has triggered the management to deal with these phenomena by setting the right and best strategies and at the same time, to ensure company's growth in the future. This study tests empirically the implication of corporate-control transaction announcement on companies’ abnormal returns. Particularly, this study investigates the effect of the announcement of corporate-control transactions’ type (merger and acquisition, sell-off, joint venture, alliance) and focus (transformative or expansionist). It used the event study of 94 corporate-control transactions, which contains of transactions’ type and focus of during 1991-2001 periods. By using multivariate regression analysis, the results show that the announcement of corporate-control transactions significant and positively influence the cumulative abnormal return. Meanwhile, the announcement of the corporate-control transactions’ type and focus does not significantly influence stockholders' benefit. Generally, the characteristic of the independent and control variables in this study due to their implications to cumulative abnormal return are in-line with previous studies. In addition, this study has proven that the characteristic of investors in Indonesia's stock markets are very different with the ones in many other places like Europe or United States. In other words, this reflects the unstable and inefficiency of Indonesia's stock market as an emerging market
Exchange in the barranco: Organizing the internal economy
This thesis problematizes the infrastructural and social boundaries of informal settlements established in anomalous depressed tissues within the gridded city. It does so by proposing a new urban strategy that intends to dissolve the edge condition as well as reconnect extracted points of the settlement as a means to pulsate the activity of the slum dwellers and to incorporate the informal settlement to the city. This new urban approach weaves the inverted topography of the barranco with two pieces of urban fabric that are interrupted.
It explores La Limonada, one of Guatemala City's densest and most dangerous asentamientos situated in a barranco.
The thesis grows out of three constants of this informal city: informal economies, steep grounds and lack of connectivity and proposes an acupunctural construction of exchange promenades that act as connective infrastructures, exchange platforms, and new public grounds. This Mobilizer engenders a new tectonic paradigm that serves a mediator in this gradient of exchanges between the consolidated city and the asentamiento
Límites de velocidad y distancia en la transmisión de información por un enlace óptico de bajo costo con recuperación libre de ruido
ABSTRACT: In this paper we present the results of the information transmission by a conventional fiber optic network of low cost. The information to be transmitted is stored in a quick response code (QR code) and the transmission effects over the QR for different values of the bit rate and fiber length are analyzed. The simulations were performed using the software for optical devices and links VPI photonics. The implemented optical network does not use expensive optical devices such as doped fibers to amplify, dispersion compensating fibers or correction errors algorithms. The received QR code contains different kind of distortions generated by the conventional fiber optic network. The transmitted results are analyzed using the bit error rate and signal noise ratio parameters. The results showthat the original information can be recovered without any kind of distortion for considerable distances and transmission rates due to tolerance to noise that exhibit the QR codes.RESUMEN: En este trabajo se presentan los resultados de la transmisión de información por una red de fibra óptica convencional de bajo costo. La información a transmitir se almacena en un código de respuesta rápida (código QR) y se analizan los efectos que produce la transmisión sobre el código QR para diferentes valores de la tasa de bits y la longitud de la fibra. Las simulaciones se realizaron con el software para enlaces y dispositivos ópticos VPI photonics. La red óptica implementada no usa dispositivos ópticos costosos tales como fibras dopadas para amplificar, fibras compensadoras de dispersión o algoritmos de corrección de errores. El código QR recibido contiene diferentes tipos de distorsiones generadas por la red de fibra óptica convencional. Los datos transmitidos se analizan usando como parámetros la tasa de error binario y la relación señal a ruido. Los resultados muestran que la información original puede ser recuperada sin ningún tipo de distorsión para distancias y tasas de transmisión considerables, debido a tolerancia al ruido que exhiben los códigos QR
Estrategias de aprendizaje y rendimiento escolar en el área de matemática en los estudiantes del quinto grado de secundaria de la I. E. N° 7075 “Juan Pablo II”, Chorrillos – Lima, 2011
La investigación se planteó como problema general, ¿qué relación existe
entre las estrategias de aprendizaje y el rendimiento escolar en el área de
matemática en los estudiantes del quinto grado de secundaria de la institución
educativa N° 7075 “Juan Pablo II”, Chorrillos – Lima, 2011? y se estableció como
objetivo general determinar la relación que existe entre las estrategias de
aprendizaje y el rendimiento escolar en el área de matemática.
La metodología que se empleó fue de tipo básica con diseño no
experimental transversal descriptivo correlacional. Se trabajó con una muestra de
100 estudiantes de una población de 135. Para la recolección de datos sobre
estrategias de aprendizaje se utilizó como instrumento un cuestionario con 40
ítems en la escala de Likert y para recoger los datos del rendimiento escolar en el
área de matemática se utilizó las actas consolidadas de evaluación integral del
nivel de educación secundaria EBR – 2011. Para la codificación física y análisis
de los datos se utilizó el programa Excel y el programa estadístico SPSS 19.
Los resultados indicaron que existe una correlación positiva considerable
entre las estrategias de aprendizaje y el rendimiento escolar porque el coeficiente
Rho de Spearman fue 0.803 y el valor de p = 0.000 < 0.05, por lo cual se rechaza
la hipótesis nula y se acepta hipótesis alterna, es decir, existe una relación directa
y significativa entre las estrategias de aprendizaje y el rendimiento escolar en el
área de matemática en los estudiantes del quinto grado de secundaria de la
institución educativa N° 7075 “Juan Pablo II” del distrito de chorrillos
Cirugía abierta frente a cirugía artroscópica en el tratamiento de la inestabilidad anterior de hombro
Se analizan los resultados de una técnica convencional, técnica de Bankart,
para el tratamiento de la luxación recidivante anterior de hombro frente a una intervención
artroscópica descrita por Rose. Se seleccionan quince pacientes para cada grupo de estudio
con un seguimiento postoperatorio medio en torno a los dos años. Los pacientes de cirugía
artroscópica se han seleccionado en base a criterios de exclusión preoperatorios e intraoperatorios
que requieren la exploración de la estabilidad bajo anestesia y el examen artroscó-
pico inicial. En el grupo de cirugía abierta no existe ningún caso de recidiva de la lesión,
sólo un paciente no recuperó su nivel de actividad prelesional pero el 73 % de los pacientes
presentan restricciones leves de la rotación externa a 90 ° de abducción. En el caso de la cirugía artroscópica un paciente sufrió un nuevo episodio de luxación, dos pacientes no recuperaron su nivel previo de actividad y el 86% presentaban una movilidad completa. Los
resultados animan a los autores a continuar desarrollando las técnicas de estabilización artroscópica.We review the results of a conventional technique, Bankart repair, for the treatment
of recurrent anterior shoulder instabüity versus an arthroscopic technique developed by
Rose. Fifteen patients have been selected for each study group with an average postoperative
follow-up around two years. Gandidates for arthroscopic surgery have been selected based on
preoperative and intraoperative exclusion criteria. Intraoperative criteria required evaluation
of stability under anesthesia and diagnostic arthroscopy. In the open surgery group no redislocations
happened. Only one patient did not recover bis previous activity level but 73% had
slight restriction to external rotation at 90 ° abduction. In the arthroscopic surgery patients,
one of them suffered a redislocation, two cases did not recover their previous activity level but
8 6% kept full shoulder motion. The results encourage the authors to continue the developing
trend of arthroscopic stabilization techniques
