Is season of birth related to developmental dyslexia?

Different moderators/mediators of risk are involved in developmental dyslexia (DD), but data are inconsistent. We explored the prevalence of season of birth and its association with gender and age of school entry in an Italian sample of dyslexic children compared to an Italian normal control group. The clinical sample included 498 children (345 boys, mean age 10.3 ± 2.1 years) with DD, the control sample 1,276 children (658 boys, mean age 10.8 ± 2.2 years) from four elementary schools from the same urban area, and with the same socio-economic status level. A prevalence of birth in autumn was found among children with DD compared to controls (34% versus 24%, p < 0.0001). Children with DD were more frequently males (p < 0.0001) and had a lower mean age of school entry (p < 0.0001). Regarding the distribution of ages, 11.4% of children with DD, but none of the subjects in the control group, started school before 5.7 years. Therefore, greater risk of DD was related to age of school entry (OR = 2.72), gender (OR = 2.16), and season of birth (OR = 1.21). Significant interactions between boys with DD born in autumn, and correct school of entry (OR = 2.56) were joint predictors of higher risk of DD. The association between birth in autumn and DD may be explained by the earlier age of school entry, which may be a critical element in the youngest children with DD or at risk to DD. Whether Italian school policy is oriented to anticipate the school entry, a closer detection of early learning disorders and associated risk factors (familial load, specific language disorders, and attention deficit hyperactivity disorder) should be warranted.     

“Urban-Rural” Dynamics and Indigenous Urbanization: The Case of Inuit Language Use in Ottawa

The establishment of cities in Canada has played a pivotal role in the displacement, dispossession, and marginalization of Indigenous peoples. Yet, more than half of the Indigenous population now resides in cities, and urbanization continues to increase. This paper addresses a specific aspect of Inuit mobility—namely, migration and the dynamic use of Inuit language and knowledge in the city of Ottawa. Drawing on community-based participatory research in collaboration with an Ottawa Inuit literacy centre, we investigate a range of Inuit-led educational practices that emerged from collaborative work with a group of Inuit women. Suggested activities drew on semiotic resources—including objects and language—that involved retracing the migrational trajectories of Inuit between cities and between nonurban communities, particularly those in their Arctic “homelands.” Such practices appear to cut across the “urban-rural divide,” particularly since cities were rarely mentioned, a fact that seems to signal the irrelevance of this dichotomy for urban Inuit. In this context, the exploration of artifactual literacies—more specifically, speaker interactions that unfold around culturally meaningful objects—led to the following conclusions: (1) multilingual oracy is key to complex transcontextual meaning making; (2) spatiotemporal reference is anchored both in individual experience and in connectivity with members of a newly constituted community; and (3) there is a sharing of cross-generational horizontal knowledge, which includes the abstention from any enforcement of a linguistic norm.     

The ethnic minority achievement grant: a critical analysis

This article critically analyses the extent to which the Ethnic Minority Achievement Grant (EMAG) has been successful in meeting its core objective of raising the achievement of minority ethnic groups who are at risk of underachieving. The article provides an historical analysis of the Grant, sets the Grant within the context of the Labour government’s policies relating to minority ethnic groups and social inclusion and reports on the authors’ research into the use made by Local Education Authorities (LEAs) of EMAG based on an analysis of LEA EMAG action plans. It suggests that although there have been some improvements in closing the gaps between minority ethnic achievement and national averages since the introduction of the Grant, these have been largely limited to groups receiving English as an Additional Language (EAL) support, although these groups continue to underachieve. Further the relative achievement of some groups, notably Black Caribbean pupils, has not improved at all since the introduction of the Grant. The article proposes that if the government wishes to more effectively tackle minority ethnic underachievement then it needs to increase the overall amount spent on the Grant, which has been frozen in recent years, and demonstrate more commitment to tackling institutionalized racism within the education system and the national curriculum. Although the government is issuing guidance to schools to address historic weaknesses in the way that the Grant has been deployed, the guidance itself does not go far enough in acknowledging the role of schools and particularly LEAs in tackling underachievement. Nor does the proposed new guidance recognize the importance of including the perspectives of local Black and Asian communities in decisions on how the Grant is deployed.     

The Effect of Implicit Stereotypes on the Physical Performance of Older Adults

The purpose of this study was to explore how stereotypes affect physical performance in older adults. During Experiment 1, older adults were primed with objects representing aging stereotypes to determine whether these objects can activate stereotypes of aging. Results from the first part of this study provide evidence that certain material objects have implicit meaning and can activate stereotypes of aging. During Experiment 2, 96 community dwelling older adults were randomly assigned to one of three groups: exposure to positive stereotypes of aging (n = 32), exposure to negative stereotypes of aging (n = 32), or a neutral condition (n = 31). Gait speed, standing balance, and lower extremity muscle performance were tested before and after exposure to the objects. Results revealed no significant differences between those exposed to positive stereotypes, negative stereotypes, or the neutral condition. Physical performance was not affected by exposure to objects related to stereotypes of aging. Compared to lab settings where stereotypes are activated on a subliminal level, there may be multiple factors competing for the control of behavior when stereotypes are presented as objects, which may lessen the effect of stereotype activation on behavior.

Through the Looking Glass: Twenty Years of Chinese Internet Research

This article is a report on a research project that collected detailed information on articles, book chapters, books, and so on, published by academics on the Chinese Internet between 1990 and early 2013. The findings of the meta-review of 20 years of Chinese Internet research, as gleaned from quantitative and qualitative analysis of the collected body of publications, are presented and discussed in this report. It engages with the conclusions drawn by previous meta-studies, and seeks to shed a critical, self-reflexive light onto the main discursive formations of their research field. The article concludes that there is still a lot of scope for growth in studies of the Internet in China and lists several of the identified research gaps.     

Extreme case learning: the manager perspective on rare knowledge and capabilities development

International strategy is enhanced by organizations’ ability to learn in host markets; yet, it remains ambiguous how post-entry knowledge gaps between home – and host country shape MNE’s absorptive capacity. This article builds on the specific contributions of ‘extreme case’ internationalization to advance literature in this field. We foster the understanding of the role of rare knowledge and the mechanisms that link knowledge acquisition to absorptive capacity dynamics used in the internationalization path of multinational enterprises (MNEs). We opt for in-depth qualitative research into the post-entry phase of ‘extreme’ (thus particularly crude) international joint venture (IJV) investment, and analyze the perspective of managers from a developed economy MNE located in a high-risk, weak-institutions host country. The firm’s absorptive capacity and its interaction with external environments that are categorized into four distinct contexts are found to be contingent upon pro-active experiential learning, concurrent to managerial willingness and simultaneous organizational commitments to learning and to exploiting rare knowledge. We thus uncover managerial perceptions of a knowledge gap identified as host-country challenges and resulting managerial solutions, which reveal rare learning opportunities and knowledge exploitation dynamics. The capacity to compensate for knowledge gaps is a critical key within the design and consolidation of an alternative internationalization path for developed-country MNEs. This challenges the traditional risk–return–commitment dependencies in prior literature.     

Kieferchirurgische Operationsplanung mit Hilfe von Techniken der virtuellen Realit?t

Für ein vollst?ndig computergestütztes Planungssystem zum Zwecke der kieferchirurgischen Operationsplanung ist die Bereitstellung von virtuellen Werkzeugen für den Chirurgen eine grundlegende Voraussetzung. Ausgehend von den Volumendaten mit Sch?del- und Kieferknochen des Patienten erm?glicht ein einfaches Interface unter Verwendung einer geeigneten Visualisierung und haptischer Eingabeger?te die interaktive Definition und Manipulation einzelner virtueller Knochensegmente. Wir haben moderne kraftrückgekoppelte Ger?te aus dem Niedrigpreisbereich eingebunden und auf ihre F?higkeit untersucht, das dreidimensionale Verst?ndnis im Planungsproze?durch Anlehnung an die Vorg?nge bei der chirurgischen Prozedur zu erh?hen. Durch diese Eingabeger?te ist es m?glich, die Knochensegmentierung für eine Osteotomie des Unterkiefers intuitiver und schneller durchzuführen. Die definierten Teilvolumina ergeben zusammen mit ihrer r?umlichen Neuanordnung auf Grundlage einer kephalometrischen Analyse einen Operationsplan. Nach erfolgter Planung werden die Planungsergebnisse in den Operationssaal übertragen. Die intraoperativen Techniken beinhalten die Visualisierung der Planungsergebnisse, die Steuerung der Anwendung über Sprache und die Bestimmung der Patientenposition mittels eines elektromagnetischen 3D-Trackingsystems.     

Self-controlled feedback: does it enhance learning because performers get feedback when they need it?

This paper examines whether self-controlled feedback schedules enhance learning, because they are more tailored to the performers' needs than externally controlled feedback schedules. Participants practiced a sequential timing task. One group of learners (self-control) was provided with feedback whenever they requested it, whereas another group (yoked) had no influence on the feedback schedule. The self-control group showed learning benefits on a delayed transfer test. Questionnaire results revealed that self-control learners asked for feedback primarily after good trials and yoked learners preferred to receive feedback after good trials. Analyses demonstrated that errors were lower on feedback than no-feedback trials for the self-control group but not for the yoked group. Thus, self-control participants appeared to use a strategy for requesting feedback. This might explain learning advantages of self-controlled practice.
