Exploring the nexus between community cultural wealth and the academic and social experiences of Latino male achievers at two predominantly White research universities

Latino males are grossly underrepresented at four-year postsecondary institutions in the United States. This phenomenological study seeks to address this emergent educational crisis by focusing on the experiences of two Latino male achievers at predominantly White research universities. Community Cultural Wealth is used to explore how Latino male collegians with a cumulative grade point average (GPA) above 3.75 employed linguistic, resistant, and navigational capital to enhance their academic and social experiences during college. The reports offered by participants in this study are intended to advance knowledge regarding the experiences of Latino male collegians as well as to enhance research, policies, and practices that increase the educational attainment of Latina/o students within higher education.     

Incompatibility between pregnancy and educational projects,from the perspective of socially vulnerable adolescent women and men in Mexico

Research focused on adolescent pregnancy reports that this event acquires significance and has different consequences according to the context and social subjects who experience it. In this study, by means of a sample formed by adolescent women and men who are socially vulnerable in Mexico, with and without a history of pregnancy, we can see how this reproductive event turns into a factor of educational vulnerability and how their possibilities and expectations with respect to continuing in school are determined in a differentiated manner, according to gender. The findings show that adolescent pregnancy in vulnerable sectors is scarcely compatible with educational projects and that possibilities and expectations to continue in or re-enter the school system are determined by gender differences; these usually lead to fewer opportunities for adolescent women to return to school during or after pregnancy.     

The time course of the syllable frequency effect in visual word recognition: evidence for both facilitatory and inhibitory effects in French

The present study tracked the time course of the syllable frequency effect in French visual word recognition, by varying the strength of spreading activation between letters and phonological syllables. The frequency of phonological first syllables and the frequency of orthographic first syllables were conjointly manipulated in two lexical decision tasks. In Experiment 1, word parsing into syllable units was supported by orthographic redundancy. No interaction between orthographic and phonological syllable frequency was found. In Experiment 2, word parsing into syllables was not marked by orthographic redundancy. Results showed an interaction between orthographic and phonological syllable frequency: the syllable frequency effect was inhibitory when orthographic syllable frequency was high, whereas it was facilitatory when orthographic syllable frequency was low. Decreasing the strength of syllable activation (i.e., with orthographic syllables of low frequency and ambiguous syllable boundaries) prevented the activation of lexical competitors before target word recognition, leading to a facilitatory effect of syllable frequency. The present study provides evidence that the net effect of syllable frequency is strongly related to its time course, and that the strength of syllable activation, which depends on orthographic properties, determines the direction of the net effect.     

Fungal diversity in adult date palm (Phoenix dactylifera L.) revealed by culture-dependent and culture-independent approaches

Endophytic flora plays a vital role in the colonization and survival of host plants, especially in harsh environments, such as arid regions. This flora may, however, contain pathogenic species responsible for various troublesome host diseases. The present study is aimed at investigating the diversity of both cultivable and non-cultivable endophytic fungal floras in the internal tissues (roots and leaves) of Tunisian date palm trees (Phoenix dactylifera). Accordingly, 13 isolates from both root and leaf samples, exhibiting distinct colony morphology, were selected from potato dextrose agar (PDA) medium and identified by a sequence match search wherein their 18S–28S internal transcribed spacer (ITS) sequences were compared to those available in public databases. These findings revealed that the cultivable root and leaf isolates fell into two groups, namely Nectriaceae and Pleosporaceae. Additionally, total DNA from palm roots and leaves was further extracted and ITS fragments were amplified. Restriction fragment length polymorphism (RFLP) analysis of the ITS from 200 fungal clones (leaves: 100; roots: 100) using HaeIII restriction enzyme revealed 13 distinct patterns that were further sequenced and led to the identification of Alternaria, Cladosporium, Davidiella (Cladosporium teleomorph), Pythium, Curvularia, and uncharacterized fungal endophytes. Both approaches confirmed that while the roots were predominantly colonized by Fusaria (members of the Nectriaceae family), the leaves were essentially colonized by Alternaria (members of the Pleosporaceae family). Overall, the findings of the present study constitute, to the authors’ knowledge, the first extensive report on the diversity of endophytic fungal flora associated with date palm trees (P. dactylifera).     

Training Planning and Working Memory in Third Graders

Working memory and planning are fundamental cognitive skills supporting fluid reasoning. We show that 2 games that train working memory and planning skills in school‐aged children promote transfer to 2 different tasks: an attentional test and a fluid reasoning test. We also show long‐term improvement of planning and memory capacities in 8‐year‐old children after playing adaptive computer games specifically tailored to entrain these cognitive functions. Working memory capacity expanded from 5 to 7 items by using our games. Furthermore, steady progression in the task indicates that this capacity can be trained rapidly. Planning abilities persisted in a nonmarkovian form of play, where a move is highly influenced by previous moves, avoiding back‐ups. Here, we introduce a public and growing platform ( http://www.matemarote.com.ar/ ) developed for this research which has the potential for wide use in educational research.     

The Influence of Reading Expertise in Mirror‐Letter Perception: Evidence From Beginning and Expert Readers

The visual word recognition system recruits neuronal systems originally developed for object perception which are characterized by orientation insensitivity to mirror reversals. It has been proposed that during reading acquisition beginning readers have to “unlearn” this natural tolerance to mirror reversals in order to efficiently discriminate letters and words. Therefore, it is supposed that this unlearning process takes place in a gradual way and that reading expertise modulates mirror‐letter discrimination. However, to date no supporting evidence for this has been obtained. We present data from an eye‐movement study that investigated the degree of sensitivity to mirror‐letters in a group of beginning readers and a group of expert readers. Participants had to decide which of the two strings presented on a screen corresponded to an auditorily presented word. Visual displays always included the correct target word and one distractor word. Results showed that those distractors that were the same as the target word except for the mirror lateralization of two internal letters attracted participants' attention more than distractors created by replacement of 2 internal letters. Interestingly, the time course of the effects was found to be different for the 2 groups, with beginning readers showing a greater tolerance (decreased sensitivity) to mirror‐letters than expert readers. Implications of these findings are discussed within the framework of preceding evidence showing how reading expertise modulates letter identification.     

Outcomes of a scientific nonformal educational initiative for youth in Rio de Janeiro

The aim of this research is to understand how former students view their professional and academic paths after taking part in a specific scientific nonformal educational initiative during high school. This program is called Vocational Scientific Program (Provoc) and is carried out in the Oswald Cruz Foundation (Fiocruz), Rio de Janeiro, Brazil. This institution has for over 100 years played a pioneer role in public health research in the country. This institution has many graduate programs and a high school dedicated to training students in health issues. Provoc was originated in this school and has been part of it for the last 25 years. Since its beginning, this program has been characterized by a significant predominance of women which relates to the female predominance of professionals in this institution working in the traditional areas of Fiocruz, which are Biology, Medicine, Public Health, Humanities and Social Sciences. This study was qualitative in nature and involved observations and 34 individual interviews, which followed a semi structured questionnaire, designed for this research. The results indicate that the majority of participants see their program participation experiences as an asset in their academic and professional careers. Many describe feeling empowered by presenting their work in seminars and a few by writing a research article. Many former students also testified to the establishment of social long lasting relationships in the research work environment. And finally, the interviews reveal a few moments and the factors involved in the selection of a profession by youth.     

Talking about death: Implementing peer discussion as a coping mechanism to overcome fears about dissection,death, and dying

Many studies have reported on the perceptions of medical students toward dissection. It is important to understand the feelings and symptoms experienced during dissection so that they can be adequately handled. Prior to dissection, first year students are given lectures on aspects of dissection, death and dying, and death rituals in various cultures. Two separate questionnaires, one given during the first week of dissection and another given one month into the program were then completed anonymously by dissection groups. The questions were designed to be open‐ended, thereby encouraging group discussion amongst students. The questionnaires were used to determine the perception of students to dissection and to discover if these perceptions change during the dissection program. The first questionnaire revealed that students do experience fears and anxiety prior to and at the beginning of dissection; however, most of these fears dissipated by the time of the second questionnaire. One month into dissection students cited talking to peers as their main coping mechanism and fewer students mentioned emotional detachment from their cadaver as a coping mechanism, as was the case in the first questionnaire. Dissection was perceived as a positive experience by our student cohort and most students cited the main advantage of dissection as the ability to visualize organs in three dimensions. The comprehensive answers received from the students indicated that thorough discussion of feelings amongst peers occurred, introducing students to an important coping mechanism at an early stage of their learning.

Planning Istanbul’s Public Library System

The paper is an attempt to analyse the role of Nigerian television (TV) journalists as major participants in mass information production, transfer, and, delivery. The analysis centres on the legal, political, economic, and cultural contexts in which the TV journalists operate, and the dangers, problems, and frustrations involved in this operation. It also analyses the strategic role of the TV and its impact as a medium of mass information. The paper concludes by analyzing how TV programming orientation has been skewed in favour of more literate urban and semi-urban populations, and how Nigeria's legal, political, economic, and cultural environments are unfavourable for conscientious and conscious TV journalists. It suggests that only when the TV journalists re-orient themselves and assert their right as people's conscience can they mobilize society for positive change.
