Participatory filmmaking with Qur'anic students in Kano, Nigeria: ‘speak good about us or keep quiet!’

‘Participatory’ research is often presented as a means to ‘empower’ stigmatised groups by addressing shame and by promoting attitude changes. Drawing on experiences producing a ‘participatory’ docudrama with traditional Qur’anic students (almajirai) in Kano, northern Nigeria, I reflect on the limits of ‘participatory’ research as a tool for ‘empowerment’. I describe the risks stigmatised groups may incur by participating, and consider to what extent, if at all, it can foster social change. The almajirai have attracted negative attention as presumed victims of child neglect and as ‘cannon fodder’ for Islamic radicalisation. Their participation in the filmmaking gave them an opportunity to voice their concerns and to rebuke those treating them heedlessly. At the same time, they became vulnerable to accusations and suspicions within their communities. To escape the negative connotations of poverty, they deemphasised its role for almajiri enrolment, thus concealing structural inequalities

Accomplice, patron, go-between? A role to play with poor migrant Qur’anic students in northern Nigeria

What does it mean to conduct ethnographic research in a context where inequalities are pervasive? Drawing on experiences conducting research with poor migrant Qur’anic students (almajirai) in Kano, northern Nigeria, this article explores the challenges of establishing productive and ethical research relationships with informants whose social and socioeconomic status is significantly lower than that of the researcher. The article argues that large socioeconomic and educational inequalities demand a rethinking of the subject positions available to researchers in such contexts. In the article, I consider in turn my roles as an ‘accomplice’ of exclusionary elite behaviour, as a ‘patron’ for my informants, and as a ‘go-between’ facilitating access for them to otherwise inaccessible ‘social microworlds’

Transnational migration and educational change: examples of Afropolitan schooling from Senegal and Ghana

Studies on migration and education have examined homeland returns as part of family strategies around acquiring desired cultural capital. However, the impact of return migration and transnational mobility on homeland educational landscapes remains under-researched. Using ethnographic data from Ghana, Senegal, the UK and the US, this paper shows how ‘international’ schools on the African continent have emerged as places where young transnational Africans can acquire cosmopolitan and Afropolitan competencies and outlooks

Mobility, social reproduction and triple minority status: young Senegalese-Americans’ experiences of growing up transnationally

A growing body of literature explores how transnational migration from Africa to Western countries affects childrearing practices. While the motivations and constraints underpinning parents’ decisions to raise children partly or entirely in the ‘homeland’ are fairly well documented, much less is known about young people’s experiences of transnational mobility and about its relationship to social reproduction. Drawing on data collected over 14 months among Senegalese migrant communities in New York and New Jersey, and in Islamic schools receiving migrants’ children in Dakar, Senegal, this paper explores how educational stints in the ‘homeland’ equip young people with cultural and religious resources to deal with the challenges of living in the US as part of a triple minority as Blacks, immigrants, and Muslims. At the same time, homeland stays produce a series of new vulnerabilities, as young people struggle to adjust to an unfamiliar language and disciplinary regime in the US

Pitfalls of downside performance measures with arbitrary targets

The Sharpe ratio has been criticized with regard to the assumptions of mean-volatility portfolio selection. Downside performance measures were developed to resolve this critique; they are consistent with expected utility under less restrictive assumptions. The most prominent family of downside performance measures is known as Kappa ratios and puts above target returns into relation to lower partial moments. While the Sharpe ratio of a mutual fund examines whether portfolios of mutual fund and risk-free asset dominate risk-adjusted passive portfolios of benchmark and risk-free asset, this characteristic cannot be transferred to downside performance measures with arbitrary targets. We show that Kappa ratios assign different values to passive strategies with varying fractions of benchmark and risk-free asset if the target differs from the risk-free rate. This effect can lead to reverse rankings of inferior and superior performing mutual funds. In addition, even the ratio of excess return and excess downside risk of passive portfolios is not constant in general. Therefore, downside performance measures turn out to be only applicable in asset management if the target is set equal to the risk-free rate

Senegalese migrants’ children, homeland returns, and Islamic education in a transnational setting

Homeland visits and stays have only recently began to receive attention within the growing literature on the religious beliefs and practices of ‘second generation’ Muslims in Western contexts, just as African Muslims have largely been neglected within this emerging field. Drawing on data collected over a total of 14 months among Senegalese migrant communities in the greater New York area, and in Islamic schools receiving migrants’ children in Dakar, Senegal, this paper outlines how young people’s homeland returns for the sake of religious education give rise to complex negotiations of meaning and identity

Collaboration With Community Partners to Enhance Clinical Practice

Teacher preparation programs are shifting focus to models that integrate pedagogy and coursework into an applied clinical teaching model. Research clearly supports this change to help new teachers prepare for the demographics of today’s classrooms. Teacher preparation is improved through the implementation of high-leverage practices, the key skills new teachers are expected to know and apply. This article highlights a collaborative professional development day designed to strengthen the clinical partnership by developing a shared vision and common language by incorporating high-leverage practices

Simulation of space-borne tsunami detection using GNSS-Reflectometry applied to tsunamis in the Indian Ocean

Within the German-Indonesian Tsunami Early Warning System project GITEWS (Rudloff et al., 2009), a feasibility study on a future tsunami detection system from space has been carried out. The Global Navigation Satellite System Reflectometry (GNSS-R) is an innovative way of using reflected GNSS signals for remote sensing, e.g. sea surface altimetry. In contrast to conventional satellite radar altimetry, multiple height measurements within a wide field of view can be made simultaneously. With a dedicated Low Earth Orbit (LEO) constellation of satellites equipped with GNSS-R, densely spaced sea surface height measurements could be established to detect tsunamis. This simulation study compares the Walker and the meshed comb constellation with respect to their global reflection point distribution. The detection performance of various LEO constellation scenarios with GPS, GLONASS and Galileo as signal sources is investigated. The study concentrates on the detection performance for six historic tsunami events in the Indian Ocean generated by earthquakes of different magnitudes, as well as on different constellation types and orbit parameters. The GNSS-R carrier phase is compared with the PARIS or code altimetry approach. The study shows that Walker constellations have a much better reflection point distribution compared to the meshed comb constellation. Considering simulation assumptions and assuming technical feasibility it can be demonstrated that strong tsunamis with magnitudes (<i>M</i>) ≥8.5 can be detected with certainty from any orbit altitude within 15–25 min by a 48/8 or 81/9 Walker constellation if tsunami waves of 20 cm or higher can be detected by space-borne GNSS-R. The carrier phase approach outperforms the PARIS altimetry approach especially at low orbit altitudes and for a low number of LEO satellites
