A Qualitative Study on Book Clubs and Dialogic Literary Gatherings in Spain and Brazil

Some organizations in Spain that seek to foster innovation in reading are keen to establish book clubs or dialogical literary gatherings. However, there are notable differences between these two practices that are not always clear. This paper presents the results of an observational study based on participant observation and interviews with key informants that tackle their similarities and differences in school and social settings. The results show that their differences lie in origin, purpose, methodology, and coordination, among others. The conclusions show different paradigms behind these practices, and organizations should opt for one or the other.     

Swirling Students: Articulation Between A Major Community College District and a State-Supported Research University

As the country experiences a recession and institutions of higher education increase tuition to compensate for diminishing state support, the transferability of credits among and between institutions is essential to students seeking to earn a baccalaureate degree. Students, parents, and taxpayers cannot afford to pay twice for the same courses or for additional courses. In this environment, articulation becomes a very important issue, particularly when research has shown that a significant number of students enroll in more than one institution on their path to a degree. The focus of this article is the swirling students between the Maricopa Community Colleges and Arizona State University. Swirling students, also a national phenomenon, encounter a number of challenges that institutions need to address. The history of articulation agreements in Arizona was explored to provide insight into the transfer model available to students enrolled at the Maricopa Community Colleges and Arizona State University. The data revealed that the extent of student swirl is greater than initially anticipated and transcends beyond lower division coursework into the senior year. After considering the findings and conclusions based on the data, this article concludes that transparent institutional intentionality is imperative to effective articulation agreements that accommodate student swirl.     

Individual Differences in Categorical Perception Are Related to Sublexical/Phonological Processing in Reading

This article examines the relationship between individual differences in speech perception and sublexical/phonological processing in reading. We used an auditory phoneme identification task in which a?/ba/-/pa/?syllable continuum measured sensitivity to classify participants into three performance groups: poor, medium, and good categorizers. A lexical decision task manipulated syllable and word frequency. We found that the two tasks were associated. Poor categorizers did not present the typical syllable frequency effect; however, the other groups were sensitive to phonological information to differing degrees and showed the inhibitory syllable frequency effect only for low-frequency words. These results suggest that auditory phoneme identification efficiency may be related to the sublexical processes involved in reading words.     

Dynamics of Acculturation, Enculturation, and Ethnic Identity: Influence of Psychocultural Constructs on Conscientiousness and Expectations of Higher Education Among Latinos

This study investigated the influence of psychocultural variables (e.g., acculturation, enculturation, ethnic identity) and personality characteristics in relation to educational expectations among 345 Latino middle school students in the U.S. Results from a path model indicate that 24.4?% of the variance of educational expectations was accounted for by all predictor variables included in the model. Age, acculturation, and conscientiousness had statistically significant direct effects on educational expectations. Findings also show that elements of ethnic identity and conscientiousness mediated the association from acculturation and enculturation to educational expectations. Implications of the findings for counselors are addressed.     

Beyond decoding deficit: inhibitory effect of positional syllable frequency in dyslexic Spanish children

This study explores whether activation and inhibition word processes contribute to the characteristic speed deficits found in transparent orthographies (Wimmer, Appl Psycholinguist 14:1–33, 1993). A second and fourth grade sample of normal school readers and dyslexic school readers participated in a lexical decision task. Words were manipulated according to two factors: word frequency (high vs. low) and syllable frequency (high vs. low). It has been repeatedly found that words with high-frequency syllables require extra time for deactivating the lexical syllabic neighbors: the so-called inhibitory effect of positional frequency syllable (Carreiras et al., J Mem Lang 32:766–780, 1993). We hypothesized that dyslexic readers would show a stronger inhibitory effect than normal readers because they are slower decoders and they may also be slower at the activation and inhibition of word representations that are competing (i.e., syllabic candidates). Results indicated an interaction between word and syllable frequency (i.e., a strong inhibitory effect was found in the low-frequency word condition). According to our hypothesis, the inhibitory effect size was almost three times bigger in dyslexics than in the normal readers. This difference shows an alteration, not a developmental lag. Interestingly, the inhibitory effect size did not interact with school grade. Thus, reading experience did not impact the lexical processes involved on the inhibitory effect. Our outcomes showed how activation and/or inhibition of lexical processes can contribute to the lack of speed beyond decoding deficit.     

Social Support,Psychological Well-being,and Health Among the Elderly

This article is based on the influence that participation in the Third Age University Program has on the health and well-being of the elderly and with the mediation of social support. The data were obtained from a longitudinal study of 147 elderly students of the Third Age University of Seville (Spain). The hypothesis was that the elders who belong to the program would have, as a consequence of their participation in it, better health, well-being, and social support. The results revealed the influence that social support exercises on well-being and, as a result, upon health.     

Purposeful play during learning centre time: from curriculum to practice

This article explores the correspondence between the vision of play articulated in Singapore’s national kindergarten curriculum framework and the play-related pedagogies enacted by teachers on the ground, particularly during Learning Centre Time (LCT). Influenced by neo-liberal ways of thinking, the curriculum states that purposeful play is a medium to achieve intended learning outcomes. The study is part of a longitudinal project where 108 Kindergarten 1 classrooms were videotaped during a full ‘typical day’ (3–4 h). While learning centres were set up in all classrooms, only 36 LCT episodes were identified. Certain learning centre types (literacy, arts) were more common than others (numeracy, science), and time spent by teachers in the different centres varied widely. Children were allowed limited freedom of choice while playing in learning centres, and some were even required to complete assignments. While teachers tended to adopt facilitative roles, quality of instructional support provided to children was low. We conclude that pedagogical practices during LCT in the observed classrooms do not adequately reflect the curriculum’s vision of purposeful play. This theory/practice gap might be due to curriculum expectations, teacher-related factors (beliefs, lack of preparation) and parental pressures. Implications, limitations and lines for future research are discussed.     

Microfluidic study of the chemotactic response of Escherichia coli to amino acids,signaling molecules and secondary metabolites

Quorum sensing and chemotaxis both affect bacterial behavior on the population level. Chemotaxis shapes the spatial distribution of cells, while quorum sensing realizes a cell-density dependent gene regulation. An interesting question is if these mechanisms interact on some level: Does quorum sensing, a density dependent process, affect cell density itself via chemotaxis? Since quorum sensing often spans across species, such a feedback mechanism may also exist between multiple species. We constructed a microfluidic platform to study these questions. A flow-free, stable linear chemical gradient is formed in our device within a few minutes that makes it suitable for sensitive testing of chemoeffectors: we showed that the amino acid lysine is a weak chemoattractant for Escherichia coli, while arginine is neutral. We studied the effect of quorum sensing signal molecules of Pseudomonas aeruginosa on E. coli chemotaxis. Our results show that N-(3-oxododecanoyl)-homoserine lactone (oxo-C12-HSL) and N-(butryl)-homoserine lactone (C4-HSL) are attractants. Furthermore, we tested the chemoeffector potential of pyocyanin and pyoverdine, secondary metabolites under a quorum sensing control. Pyocyanin is proved to be a weak attractant while pyoverdine are repellent. We demonstrated the usability of the device in co-culturing experiments, where we showed that various factors released by P. aeruginosa affect the dynamic spatial rearrangement of a neighboring E. coli population, while surface adhesion of the cells is also modulated.
