Pre-game hydration status, sweat loss, and fluid intake in elite Brazilian young male soccer players during competition

In this study, we assessed the pre-game hydration status and fluid balance of elite young soccer players competing in a match played in the heat (temperature 31.0 ± 2.0 ° C, relative humidity 48.0 ± 5.0%) for an official Brazilian soccer competition. Fluid intake was measured during the match, as were urine specific gravity and body mass before and after the game to estimate hydration status. Data were obtained from 15 male players (age 17.0 ± 0.6 years, height 1.78 ± 0.06 m, mass 65.3 ± 3.8 kg); however, data are only analysed for 10 players who completed the full game. The mean (± s) sweat loss of players amounted to 2.24 ± 0.63 L, and mean fluid intake was 1.12 ± 0.39 L. Pre-game urine specific gravity was 1.021 ± 0.004, ranging from 1.010 to 1.025. There was no significant correlation between sweat loss and fluid intake (r = 0.504, P = 0.137) or between urine specific gravity and fluid intake (r = -0.276, P = 0.440). We conclude that young, native tropical soccer players started the match hypohydrated and replaced about 50% of the sweat lost. Thus, effective strategies to improve fluid replacement are needed for players competing in the heat.     

Reconsidering SES and gender divides in literacy achievement: are the gaps across social class and gender necessary?

This study evaluated factors within families that enhance kindergarten reading readiness of children and are also linked to maternal education (a common proxy for SES). We were interested in identifying factors that would be more accessible to families and school administrators as sources of potential change than broad and un-malleable reflections of socio-economic status. Consistent with current research, we found that maternal education had a broad impact on the reading readiness of children. Maternal education was linked to the amount of time children spent with non-literary media (television, computers, videos, video games). Re-running analyses using time with media as a covariate resulted in reduced differences in reading outcomes of children as a function of maternal education. Effects of maternal education were reduced by the end of the kindergarten year, indicating that literacy programming implemented by the school was successful in closing this academic gap.     

The Ancient Mariner and the transit of Venus

The achievements of William Wales FRS – astronomer, classical scholar, demographer, editor, mathematician, meteorologist and humane teacher – have been overshadowed by the fame of Cook's extraordinary voyages, and overlooked as a significant influence on Samuel Taylor Coleridge's early development. The Royal Society sent Wales to Hudson Bay, Canada, and James Cook to Tahiti, both to observe the 1769 transit of Venus as part of an international project to calculate solar parallax, and hence the distance to the Sun. Wales later taught mathematics and navigation science at Christ's Hospital School to a precocious Coleridge, whose creative mind translated tales of polar adventures into memorable poetry.     

After German reunification: the implementation of a two-tier school model in Berlin and Saxony

In the last two decades, many German states have enforced a partial integration of school types and have transformed their school systems into a two-tier model. The traditional tripartite school model, for which Germany has long been known, is thus no longer a characteristic of their school systems. This article analyses the determinants of the structural changes in Berlin and Saxony by applying concepts of historical institutionalism. In both states, the reform of the schools’ structures can be described as path dependent, but also a specific constellation of interests, strategies and actors led to a partial erosion of the respective traditional structures.     

Knowing Who You Are for Not Feeling Lonely? A Longitudinal Study on Identity and Loneliness

In adolescence, both identity concerns and feelings of loneliness are of utmost importance to the experiences of young people. Yet, a theoretically grounded hypothesis that identity and loneliness are developmentally related has never been tested. Thus, the aim of this study was to disentangle the longitudinal associations between identity processes in educational and interpersonal domains and loneliness in adolescence. The sample consisted of 632 Lithuanian adolescents (53.2% girls; M_age = 14.32; SD_age = 1.09) participating in a four-wave study with 6-month intervals between assessments. Cross-lagged analyses revealed reciprocal associations between identity processes and loneliness in the educational domain and unidirectional effects of adolescents' reconsideration of commitment on loneliness in the interpersonal domain.     

Punditry as a reward system: audience construction and the logics of the punditry sphere

The article explores the relationship between the punditry sphere and democracy by analyzing how pundits and media organizations think about their audience. It also examines the role of punditry in the political environment in which the media organizations operate. Using Portugal as an example, the study draws on data gathered from interviews with pundits, journalists and news editors. Findings suggest that pundits and media organizations construct a punditry sphere that revolves around the circles of power. The article argues that this conception of the punditry sphere reflects the reward system under which pundits and media organizations work. Punditry seems to be a field primarily oriented to pundits themselves and to managing their stakes in the public arena while operating as a sphere where media organizations rework their relations with and within established powers, where politicians hold a special place. This construction reflects the co-dependence between media organizations and circles of power in Portugal and offers organizational-structural understanding of the logics of the punditry sphere and the role pundits play in public communication.     

Working with practitioners’ perspectives: supporting father involvement in family services in England

The paper draws on a study aiming to work with practitioners’ perspectives to support involvement through family services. Data were collected from a cluster sample of practitioners conducting father groups in south-west England. The paper focuses upon working with their perspectives. Two issues in their perspectives were associated with ‘masculinity’ and ‘blocks’ preventing father involvement. Using an interventionist-based method known as the ‘change laboratory’, conducted through a series of development work research (DWR) workshops, practitioners reflected on contradictions in their practice. Implications from the study suggest that, first, if practitioners identify contradictions with which they work, they can explore possibilities for developing their work. Second, being an involved father may be played out differently in terms of identity, according to social and cultural contexts. By implication, practitioners can help fathers to express themselves in several identities and support them in their understanding, through being part of a group.     

The interplay between structure and agency in the enactment of STEM policy

In their paper, Hoeg and Bencze argue that current STEM curriculum guidelines prioritise the training of a workforce in detriment of a democratically grounded education for citizenship. We agree that there is an insufficient questioning about which type of citizenship STEM curricula would favour and wish to contribute to this debate by (1) problematising different meanings and aspects of citizenship in different models of democracy and (2) exploring the dialectical nature of structure and agency in the discursive construction of educational (policy) discourse. We also discuss results from recent empirical research about teachers’ ideas on citizenship education in order to challenge views that assume a linearity between educational policy and its enactment.     

Becoming Teacher: A/r/tographical Inquiry and Visualising Metaphor

A great deal has been written about the representational use of metaphor to understand teacher candidates’/new teachers’ conceptions of teacher practice. This article will discuss recent research that explored secondary visual art teacher candidates’/new teachers’ visualising of visual metaphors to provoke their a/r/tographical inquiry into their perceptions of practice. This article engages with the Deleuzian conception becoming as well as the ontology of difference to provoke the reimagination of metaphor in research. We offer new understandings about visualising the visual in research and the methodological implications of relational research practices.     

“Oh Yeah,I’m Mexican. What Type are You?” Changing the Way Preservice Teachers Interpret and Respond to the Literate Identities of Children

This writing describes a literacy project between preservice teachers enrolled in a small university in Montana and an inner city school classroom in Kansas. It shows how the preservice teachers and children negotiate meaning at the beginning of the project as well as what the preservice teachers were learning from the children and from their teacher, Scott. Twenty-three third grade children exchanged letters, cards, drawings, autobiographies, and writing about shared literature with 24 preservice teachers for 10 weeks. Scott, the third grade teacher who assisted with the project, was a former student in Rita’s university language arts classroom and was strongly committed to demonstrating to preservice teachers the rewards of teaching in an inner city classroom ... particularly those coming from communities where people of color or linguistic diversity were few. Through shared written responses and the negotiation of meaning between two age groups, this project opened pathways for greater insight into the cultures and lives of children that the university students might otherwise not have known. It also provided myriad glimpses into the lives of real children, each with his or her own interests, life experiences, and expressive modalities thus shaping the perceptions of the preservice teachers about their role as teacher in supporting and responding to the individual strengths of each child.
