ABSTRACT

This issue of Paedagogica Historica is a product of the 39th ISCHE Conference, held in Buenos Aires, from 17 to 21 July 2017. For this reason, the journal exceptionally includes articles in Spanish. At the event, 442 papers were presented, distributed in 103 sessions in which 363 participants (271 researchers and 92 students) from 36 countries of the 5 continents participated. The central theme of the Conference – also covered in this issue – was Education and Emancipation.  相似文献

Puerto Rican adolescents (N = 105; Mage = 15.97 years, SD = 1.40) evaluated hypothetical situations describing conflicts between Latino values (family obligations and respeto) and autonomy desires regarding personal, friendship, and dating activities. Adolescents judged that peers should prioritize Latino values over autonomy, which led to greater feelings of pride than happiness. However, they believed that teens would prioritize autonomy over Latino values, which led to greater feelings of happiness than pride. Adolescents reasoned about autonomy desires as personal issues, whereas reasoning about Latino values was multifaceted, including references to conventions and concerns for others. Furthermore, judgments and reasoning depended on the type of autonomy desire and Latino value and sometimes, by participants' age and sex.  相似文献

This article uses a series of interlinked, personal vignettes to discuss the first three years of the North American Association for Environmental Education research symposium, from the perspectives of the key organizers. Seven challenges in the field of environmental education research are identified in a recent historical context, and we illustrate how the symposium sought to address them. The challenges were, that: (i) environmental education research has been marginalized in some areas and not recognized in others; (ii) environmental education research and environmental education practice need to be brought closer together; (iii) environmental education research is still in early development of a professional perspective; (iv) environmental education research has to give a voice to early career scholars and graduate students; (v) environmental education research needs to enable discourse about both process and outcomes; (vi) environmental education researchers need social learning contexts to help develop professional identities and create more meaningful dialogue to address these challenges; and (vii) methodologies, theoretical frameworks and differences in beliefs in environmental education research need to be accommodated. The last challenge is seen as the most significant with which to continue to engage, in developing open, inclusive forums for researchers of environmental education.  相似文献

The centrality of firms vis-à-vis regions underlines a general contrast between two models of producing innovations. This paper uses a new database composed of 4262 European chemical patents applied by 693 firms during 1987–1996 to compare the relative effect of firm and regional characteristics on the production of technological “hits” (highly cited patents). By using extensive controls, the main finding of the paper is that technological hits in the “traditional” chemical sectors are explained only by R&D intensity at the firm level and the scale of the research projects. Firm competencies, particularly technological specialisation, are still important in biotechnology. However, the distinct feature of the biotechnology model is that localised knowledge spillovers also matter.  相似文献

American publishers have published numerous children’s books about Barack Obama over the past several years; most take the form of informational biographies. This article reports on a research project aimed at how these books incorporate sociohistorical narratives, particularly those related to the civil rights movement. Though the features of the books might cause the reader to presume political neutrality, the books link readers to distinct Discourses (Gee, 1996), suggesting particular ideologies. In this article, we identified the following differences: (1) specific happenings from Obama’s life were included in some texts while omitted in others; (2) when the events were included, how they were framed differed; and (3) the narrative constructions of the events varied. We use the differences amongst these texts to argue for the importance of critical literacy in elementary classrooms.  相似文献

Determination of amyloid β (Aβ) isoforms and in particular the proportion of the Aβ 1-42 isoform in cerebrospinal fluid (CSF) of patients suspected of Alzheimer’s disease might help in early diagnosis and treatment of that illness. Due to the low concentration of Aβ peptides in biological fluids, a preconcentration step prior to the detection step is often necessary. This study utilized on-chip immunoprecipitation, known as micro-immunoprecipitation (μIP). The technique uses an immunosorbent (IS) consisting of magnetic beads coated with specific anti-Aβ antibodies organized into an affinity microcolumn by a magnetic field. Our goal was to thoroughly describe the critical steps in developing the IS, such as selecting the proper beads and anti-Aβ antibodies, as well as optimizing the immobilization technique and μIP protocol. The latter includes selecting optimal elution conditions. Furthermore, we demonstrate the efficiency of anti-Aβ IS for μIP and specific capture of 5 Aβ peptides under optimized conditions using various subsequent analytical methods, including matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS), capillary electrophoresis, microchip electrophoresis, and immunoblotting. Synthetic Aβ peptides samples prepared in buffer and spiked in human CSF were analyzed. Finally, on-chip immunoprecipitation of Aβ peptides in human CSF sample was performed.  相似文献
