    This project centers on the advocacy of undocumented immigrant youth to realize the passage of the Development, Relief, and Education for Alien Minors (DREAM) Act, a narrowly tailored bipartisan legislation that would provide qualifying undocumented youth a pathway to citizenship. Using a Latino/a Critical Race framework to address socio-political discourses surrounding the immigration debate, my analysis presents the ways undocumented youth communicated about their identity and agency and the ways they constructed their demands publicly in seeking passage of the DREAM Act during the years 2001 to 2010. This research purposefully departs from the traditional modality of research and conceptualizes political work as centered in the research process. To conduct this research, I spent eleven months of fieldwork participating with DREAM activist groups in California, New Mexico, and other states nationally. The data was drawn from an estimated 400 hours of fieldwork, 10 in-depth personal interviews of activists in leadership positions, and secondary accounts of the DREAM youth movement. This study\u27s findings point to three progressive phases of the DREAM social movement, with unique internal and external strategies used to advocate for social change. The first phase covers 2001 through 2007, where self-identification strategies were used to create a collective group identity that countered the negative dehumanizing typecast of illegal aliens by identifying DREAMers as exceptional students. During the second phase, from 2007 to 2009, self-representation strategies worked to unite undocumented youth through the creation of national coalitional organizations and through self-identification as undocumented and unafraid. During the third phase, spanning the months from May to December 2010, participating activists utilized strategies of self-reliance and self-identified as unapologetic DREAMers. The strategies of intervention included the use of civil disobedience tactics to petition for the legislation. This study points to a progressive sense of vocality, agency, and empowerment for the DREAM-eligible youth involved in this social movement. Finally, this study offers a discussion about the current state of the DREAM Act and includes suggestions and implications for the future of the social movement

    Get PDF
    Fumonisins are mycotoxins responsible for equine leukoencephalomalacia (ELEM) and they are produced by Fusarium species of high incidence in corn crops. In Jalisco (Mexico), six cases were confirmed by histopathological and neurological findings and fumonisins analysis. This is the first report of fumonisins in corn stover associated to ELEM cases

    Alternatives to Animal Experimentation: Its Institutional Teaching and Scientific

    Get PDF
    Although it is desirable to replace scientific procedures with live animals by other methods that do not use them, the use of animals in scientific procedures should be restricted to those areas that benefit human, animal, and environmental health. The use of animals as experimental models of observation of biological phenomena has evolved with man, to this day. The use of animals for scientific or educational purposes should be considered only when there is no other alternative and it is governed by the principles of replacement, reduction, and refinement. The scientists should be sure that the information obtainable with the experiments is not yet available or that the protocol was designed taking into account animal protection considerations. The chosen methods must use the least number of animals; provide satisfactory results; use the species with the least ability to experience pain, suffering, anguish, and damage; and be optimal for the extrapolation of results to the target species such as humans. It will be fundamental to guarantee on a scientific and ethical basis that the use of an animal is subject to a careful evaluation regarding the scientific or educational validity

    Ethical Considerations in Research and Medical Care of Menopause

    Get PDF
    Menopause is the permanent cessation of menstruation, and among the main symptoms reported have been night sweats, heat waves, increased body fat at the central level, dyslipidemia, hypertension, osteoporosis, insulin resistance, diabetes, mild cognitive impairment, depression, periodontitis, varicose veins, apnea, urinary genital discomfort, as well as dryness in the mouth and eye. The diagnosis, study, and care of menopausal or postmenopausal women have had great advances, such as recognizing the sub-inclusion of women and female animal models in basic and clinical studies and proposing in the same design of the study the analysis by sex. Subsequently, the need for specialized ethical training was identified, beginning in undergraduate, postgraduate, and clinical practice. To achieve this, several actions were carried out, such as the foundation of Women’s Health Institutes, the implementation of the Institutional and Private Committees of Ethic, and the development of validated instruments to evaluate signs and symptoms. Currently, there is no consensus that meets the ethical requirements for care and research in these patients. Efforts have been made practically by pathology, without considering together the social and psychobiological condition. What is intended in this document is to present the ethical aspects related to the study and medical care of women in menopause

    Use of agave durangensis bagasse fibers in the production of wood-based medium density fiberboard (MDF)

    Get PDF
    There is an increasing interest in using non-wood lignocellulosic materials for the production of wood-based medium density fiberboard (MDF). Agave durangensis Gentry bagasse is a waste product produced in large quantities in the mezcal industry. This study evaluated the incorporation of A. durangensis bagasse fibers (ADBF) to elaborate MDF wood-based panels. Three types of panels with different ratios (wood fibers: bagasse fibers) were investigated. The ratios evaluated were 100:0, 90:10, and 70:30. The density profiles, water absorption, and thickness swell of the panels were determined, as well as the modulus of elasticity (MOE), modulus of rupture (MOR), and internal bond (IB), according to the ASTM D1037-06a standard. The results were compared to the ANSI A208.2-2016 standard. The effect of the addition of ADBF on the properties of the panels was analyzed. Density profiles were comparable among the three types of panels, while water absorption, thickness swelling, MOE, MOR, and IB were similar between panels with ratios of 100:0 and 90:10. Panels with 10% and 30% of ADBF meet the minimum ANSI requirements for quality grade 115. It is feasible to use up to 30% of ADBF in the manufacture of wood-based MDF panels

    The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment

    Get PDF
    The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourteenth from SDSS overall (making this, Data Release Fourteen or DR14). This release makes public data taken by SDSS-IV in its first two years of operation (July 2014-2016). Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey (eBOSS); the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data driven machine learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS website (www.sdss.org) has been updated for this release, and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020, and will be followed by SDSS-V.Comment: SDSS-IV collaboration alphabetical author data release paper. DR14 happened on 31st July 2017. 19 pages, 5 figures. Accepted by ApJS on 28th Nov 2017 (this is the "post-print" and "post-proofs" version; minor corrections only from v1, and most of errors found in proofs corrected

    The 16th Data Release of the Sloan Digital Sky Surveys: First Release from the APOGEE-2 Southern Survey and Full Release of eBOSS Spectra

    Get PDF
    This paper documents the 16th data release (DR16) from the Sloan Digital Sky Surveys (SDSS), the fourth and penultimate from the fourth phase (SDSS-IV). This is the first release of data from the Southern Hemisphere survey of the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2); new data from APOGEE-2 North are also included. DR16 is also notable as the final data release for the main cosmological program of the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), and all raw and reduced spectra from that project are released here. DR16 also includes all the data from the Time Domain Spectroscopic Survey and new data from the SPectroscopic IDentification of ERosita Survey programs, both of which were co-observed on eBOSS plates. DR16 has no new data from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey (or the MaNGA Stellar Library "MaStar"). We also preview future SDSS-V operations (due to start in 2020), and summarize plans for the final SDSS-IV data release (DR17)
