The 1979 Diary Family Income and Expenditure Survey: Experience and Preliminary Results
This paper is presented at the Third National Convention on Statistics on December 13-14, 1982. The 1979 Diary Family income and Expenditure Survey (DFIES) has utilized the diary method of data collection to minimize, if not eliminate, errors and biases arising from the traditional recall-record method of soliciting information. Jointly conducted by the National Tax Research Center and National Census and Statistics Office, DFIES aims to provide reliable quantitative information regarding personal/additional exemptions and household income/expenditure patterns. This article argues for the utilization of DFIES in the Philippines. Areas for improvement of the system are also cited.income, data and statistics, survey method, data collection

The use and misuse of computers in education : evidence from a randomized experiment in Colombia
This paper presents the evaluation of the program Computers for Education. The program aims to integrate computers, donated by the private sector, into the teaching of language in public schools. The authors conduct a two-year randomized evaluation of the program using a sample of 97 schools and 5,201 children. Overall, the program seems to have had little effect on students'test scores and other outcomes. These results are consistent across grade levels, subjects, and gender. The main reason for these results seems to be the failure to incorporate the computers into the educational process. Although the program increased the number of computers in the treatment schools and provided training to the teachers on how to use the computers in their classrooms, surveys of both teachers and students suggest that teachers did not incorporate the computers into their curriculum.Tertiary Education,Primary Education,Secondary Education,Teaching and Learning,Education For All
Inside Science Resources in Retrospective â 2015 â 2020
The purpose of this report is threefold: 1. To summarize the production of the committee since its beginning in April of 2015; 2. To give credit to all the contributors for their excellent work in identifying resources of value to the STEM community; and 3. To provide an easy index for all the contributions made. A total of 63 contributions have been published in this blog, which have been written by 30 of our STS colleagues
No room for silence: The impact of the 2016 presidential race on a second-grade dual-language (Spanish-English) classroom
âÂĄQuiere sacar a todos los suramericanos! Quiere quedarse con solo los blancos,1 shouted second grader Salvador2 to his classmate Victor. They were supposed to be reading Click, Clack, Moo: Cows That Type by Doreen Cronin, but somehow the conversation had turned to the then presidential candidate for the Republican Party, Donald Trump. That was how Trump and his rhetoric entered our dual language classroom.
Far too often, the voices of students of color, their experiences, and their lives are not validated in the classroom. When Salvador and Victorâs conversation about Trump erupted, the teacher and Iâthe teacher researcher in the classroomâknew we had to bring this topic to the forefront. If two students were discussing it, the chances were that it was on the minds of many. As Costello (2016) explained, Trumpâs words and actions during the campaign impacted classrooms throughout the United States because âthe [presidential] campaign was producing an alarming level of fear and anxiety among children of color and inflaming racial and ethnic tensions in the classroomâ (p. 4).
This article examines how the teacher and I implemented culturally sustaining pedagogy (CSP) in our classroom in response to Trumpâs rhetoric about immigration. I focus on how the students, who were distressed by that rhetoric, discussed what Trump was saying about immigration, as well as on how we worked together to support them
An Analysis of Subject Coverage and Worldwide Involvement of E-LIS: the International Repository for Library and Information Science.
E-LIS, E-prints for Library and Information Science, is a subject-oriented repository initiated in January 2003 by a group of European information specialists. E-LIS is an open-access repository run by experts and editors from many different countries and with holdings originating in 110 countries. The first purpose of this study is to provide a description of E-LIS with special attention to the types of documents archived and the geographical distribution of its contributors. The second purpose is to determine the subject coverage, which is done by using several well-known bibliometric techniques. Using co-occurrences of subject terms, a cluster analysis is performed, producing four major clusters; a correspondence analysis of keywords and subject terms produces eight groups of association
Membership and Multiplicity among Very Low-Mass Stars and Brown Dwarfs in the Pleiades Cluster
We present near-infrared photometry and optical spectroscopy of very low-mass
stars and brown dwarf candidates in the Pleiades open cluster. The membership
status of these objects is assessed. Eight objects out of 45 appear to be
non-members. A search for companions among 34 very low-mass Pleiades members
(M0.09 M) in high-spatial resolution images obtained with the
Hubble Space Telescope and the adaptive optics system of the
Canada-France-Hawaii telescope produced no resolved binaries with separations
larger than 0.2 arcsec (a ~ 27 AU; P ~ 444 years). Nevertheless, we find
evidence for a binary sequence in the color-magnitude diagrams, in agreement
with the results of Steele & Jameson (1995) for higher mass stars. We compare
the multiplicity statistics of the Pleiades very low-mass stars and brown
dwarfs with that of G and K-type main sequence stars in the solar neighborhood
(Duquennoy & Mayor 1991). We find that there is some evidence for a deficiency
of wide binary systems (separation >27 AU) among the Pleiades very low-mass
members. We briefly discuss how this result can fit with current scenarios of
brown dwarf formation. We correct the Pleiades substellar mass function for the
contamination of cluster non-members found in this work. We find a
contamination level of 33% among the brown dwarf candidates identified by
Bouvier et al. (1998). Assuming a power law IMF across the substellar boundary,
we find a slope dN/dM ~ M^{-0.53}, implying that the number of objects per mass
bin is still rising but the contribution to the total mass of the cluster is
declining in the brown dwarf regime.Comment: to be published in The Astrophysical Journa
