Conjugacy class sums for induced modules: construction and applications

AbstractWe show how to construct conjugacy class sums for an arbitrary induced representation by using just one representative for each conjugacy class. Some ideas which speed up the calculation in special cases are presented together with examples. In the second part we give two applications of such class sums to monomial representations

A New Existence Proof for Ly, the Sporadic Simple Group of R. Lyons

AbstractThis paper reports on a new and independent existence proof for the sporadic simple group Ly of Lyons, using only two permutations of degree 9 606 125, computed by Cooperman, Finkelstein, Tselman, and York. We will show that these two permutations generate a group G≃Ly, by first computing a base and strong generating set for G, and then checking the two hypotheses for Ly from Lyons’ original paper. Moreover, this produces a new presentation for Ly

Fine Arts and Achievement Levels in Middle School Students

The results of the research allude to a correlation between arts education and academic achievement. The research demonstrates that the arts are important in the educational process. The fine arts role in education help strengthen students concentration, fine motor skills, and improve self esteem.Master'sCollege of Arts and Sciences: Public AdministrationUniversity of Michiganhttp://deepblue.lib.umich.edu/bitstream/2027.42/117710/1/Gollan.pd

'It's not just about fish': Assessing the social impacts of marine protected areas on the wellbeing of coastal communities in New South Wales.

Managing Marine Protected Areas (MPAs) is about managing human behaviours, but decision-making processes have traditionally focussed on ecological aspects, treating social aspects as secondary. It is now becoming more evident that an equal focus on the ecological and social aspects is required. Without the collection of information about social aspect such as impacts and sharing this as well as ecological information with communities, MPAs are at higher risk of opposition and social acceptability problems. This paper explores the development of a wellbeing framework to understand the social aspects, including the impacts of MPAs on the wellbeing of local communities. This research investigates two case study MPAs: Cape Byron and Port Stephens-Great Lakes Marine Parks in New South Wales, Australia. The MPAs are multiple-use and were implemented in 2006 and 2007, respectively. The research began with a review of the literature, followed by fieldwork, including semi-structured qualitative interviews with community members. Through thematic coding of the interview transcripts in light of the literature on assessing the social impacts of MPAs, a community wellbeing framework of domains and associated attributes was developed to investigate social impacts. Our analysis shows; first, local perspectives are crucial to understanding social impacts. Second, understanding social impacts gives insight into the nature of trade-offs that occur in decision-making regarding MPAs. Third, the intangible social impacts experienced by local communities are just as significant as the tangible ones for understanding how MPAs operate. Fourth, governance impacts have been the most influential factor affecting the social acceptability of the case study parks. We argue that failure to address negative social impacts can undermine the legitimacy of MPAs. We propose that the framework will support policymakers to work towards more effective, equitable and socially sustainable MPAs by employing much-needed monitoring of human dimensions of conservation interventions at the community level to shape adaptive management

Age of second language acquisition affects nonverbal conflict processing in children : an fMRI study

Background: In their daily communication, bilinguals switch between two languages, a process that involves the selection of a target language and minimization of interference from a nontarget language. Previous studies have uncovered the neural structure in bilinguals and the activation patterns associated with performing verbal conflict tasks. One question that remains, however is whether this extra verbal switching affects brain function during nonverbal conflict tasks. Methods: In this study, we have used fMRI to investigate the impact of bilingualism in children performing two nonverbal tasks involving stimulus-stimulus and stimulus-response conflicts. Three groups of 8-11-year-old children - bilinguals from birth (2L1), second language learners (L2L), and a control group of monolinguals (1L1) - were scanned while performing a color Simon and a numerical Stroop task. Reaction times and accuracy were logged. Results: Compared to monolingual controls, bilingual children showed higher behavioral congruency effect of these tasks, which is matched by the recruitment of brain regions that are generally used in general cognitive control, language processing or to solve language conflict situations in bilinguals (caudate nucleus, posterior cingulate gyrus, STG, precuneus). Further, the activation of these areas was found to be higher in 2L1 compared to L2L. Conclusion: The coupling of longer reaction times to the recruitment of extra language-related brain areas supports the hypothesis that when dealing with language conflicts the specialization of bilinguals hampers the way they can process with nonverbal conflicts, at least at early stages in life

Enrichment Programming for Secondary School Gifted Students: A Narrative Inquiry

The current constructivist interpretive narrative inquiry study considered the ways in which recently implemented enrichment programming on a system level was experienced by gifted secondary school learners and designated gifted teachers or contacts at the secondary schools. Through an in-depth exploration of stories of experiences that gifted students told about enrichment programming, this study offered significant insight into the unique learning needs and challenges of gifted adolescents in today’s secondary classrooms. Methods included an initial demographic questionnaire followed by a maximal variation sample of 12 participants for the second phase of the study with follow-up focus groups. Focus group interview data were video recorded, transcribed, and returned to participants to be member-checked for accuracy, omissions, deletions, or enhancements, and were subsequently analysed for patterns in experiences that offered insight into students’ and teachers’ perceptions of enrichment programming needs. Results of the study showcased alternative non-credit enrichment programming to be both appreciated and designed well, but the needs of gifted learners in the regular classroom are still not being met, as the remedial needs of struggling learners continue to take precedent in the regular classroom

The relationship between northern hemisphere winter blocking and tropical modes of variability

In the present study, the influence of some major tropical modes of variability on northern hemisphere regional blocking frequency variability during boreal winter is investigated. Reanalysis data and an ensemble experiment with the ECMWF model using relaxation towards the ERA-Interim reanalysis data inside the tropics are used. The tropical modes under investigation are El Niño Southern Oscillation (ENSO), the Madden-Julian Oscillation (MJO) and the upper tropospheric equatorial zonal-mean zonal wind . An early (late) MJO phase refers to the part of the MJO cycle when enhanced (suppressed) precipitation occurs over the western Indian Ocean and suppressed (enhanced) precipitation occurs over the Maritime Continent and the western tropical Pacific. Over the North Pacific sector, it is found that enhanced (suppressed) high latitude blocking occurs in association with El Niño (La Niña) events, late (early) MJO phases and westerly (easterly) . Over central to southern Europe and the east Atlantic, it is found that late MJO phases, as well as a suppressed MJO are leading to enhanced blocking frequency. Furthermore, early (late) MJO phases are followed by blocking anomalies over the western North Atlantic region, similar to those associated with a positive (negative) North Atlantic Oscillation. Over northern Europe, the easterly (westerly) phase of is associated with enhanced (suppressed) blocking. These results are largely confirmed by both the reanalysis and the model experiment
