Contesting the Politics of Culture, Rewriting the Boundaries of Inclusion: Working for Social Justice with Muslim and Arab Communities
This article calls on anthropologists of education to assert a more public voice attacking the ideological purposes to which the concept of “culture” has been deployed following the September 11 attacks. We must support schools, communities, and the media to address the power and politics of race and religion in contemporary social and political contexts, rather than focus primarily on multicultural education about Islamic and Arab “culture.” Finally, this article urges us to expand our knowledge of the processes of social incorporation for Muslim and Arab immigrant youth to include a deeper understanding of how global politics contribute to young people's sense of emerging identities.This is an electronic version of an article published in Anthropology & Education Quarterly, 33: 308–316. doi: 10.1525/aeq.2002.33.3.308, available online at: http://onlinelibrary.wiley.com/doi/10.1525/aeq.2002.33.3.308/abstrac
Imagining Postnationalism: Arts, Citizenship Education,and Arab American Youth
This article explores an Arab American community arts organization as a site for promoting youth civic participation and social activism. Studying a citizenship education project outside the school walls, and focusing on the arts as a medium for this work, foregrounds the role of the symbolic for engaging youth as active participants in democratic society. The article also examines the symbolic political argument for postnational citizenship that the young participants articulated through a film they produced. The original version of the article is published in Anthropology & Education Quarterly, 40(1):1-19, 2009, March. doi: 10.1111/j.1548-1492.2009.01025.x, available online at: http://onlinelibrary.wiley.com/doi/10.1111/j.1548-1492.2009.01025.x/abstractThis research was largely funded by a National Academy of Education/Spencer Foundation Postdoctoral Fellowship.

Becoming Citizens in an Era of Globalization and Transnational Migration: Re-imagining Citizenship as Critical Practice
This article examines how the perspectives and experiences of Arab American youth from immigrant communities can help educators think about what it means to teach young people to become active participants in the social, civic, and political spheres within and across the boundaries of nation-states. Arab American youths' perspectives are reflective of the transnational nature of their life experiences, as well as the unfortunate ways they have been positioned as enemy-outsiders to the United States in the aftermath of September 11, 2001. Listening closely to the experiences and perspectives of these young people yields concrete implications for designing citizenship education that reflects the changing nature of belonging and citizenship. This article proposes that we stop thinking about citizenship primarily in relation to national identifications and begin to see it as a set of critical practices—practices that give young people the tools to work for social change within and across the boundaries of nation-states.This is an electronic version of an article published in Abu El-Haj,T.

'Geef me de ruimte':Het eigenzinnige leven van Thea Beckman
The biography Make Way for Me recounts the life story of the Dutch children’s author Thea Beckman and the development of her writing within the socio-historical context of her time. Her political, educational and literary perspectives serve as the framework for portraying Thea Beckman’s two lives: the writer in the public eye and the woman she was behind closed doors. The meaning and significance of her contributions to the realm of children’s literature are also explored here through inquiry into the reception of Beckman’s works
ENC-based Collision and Grounding Avoidance System for a Green-Energy Autonomous Surface Vehicle
Autonome overflatefartøy (ASV-er) kan spille en viktig rolle i utviklingen av systemer som utforsker og observerer havet på en bærekraftig og kontinuerlig måte, selv i avsidesliggende områder og under tøffe forhold. Disse observasjonene kan gi ny og viktig kunnskap om hvordan havet og dets dynamiske prosesser endrer seg over tid, og hvordan de påvirkes av klimaendringene. AutoNauten er en bølgedrevet ASV som er godt egnet til denne typen oppdrag.
For at en ASV skal kunne operere autonomt ute på havet og langs kysten, er det helt nødvendig at den har et robust system som sørger for at den unngår kollisjoner og grunnstøtinger. Kollisjonsunngåelsessystemet må overholde de internasjonale forskriftene for forebygging av kollisjon på sjøen (COLREGS), og anti-grunnstøtings\-systemet skal kunne bruke data fra de elektroniske sjøkartene (ENCs).
Denne masteroppgaven presenterer et ENC-basert anti-grunnstøtingsystem og integrerer det i det eksisterende kollisjonsunngåelsessystemet (CAS) som er et simulasjonsbasert modell-prediktivt reguleringssystem (SB-MPC) utviklet av Johansen et al. [1] og implementert av Hagen et al. [2] [3]. Systemet er tilpasset til og implementert i AutoNauten. Systemet overholder COLREGS og kan ta hensyn til miljøfaktorer når det vurderer hva som er den beste manøveren for ASVen i en gitt situasjon.
Ulike simuleringer er utført for å teste systemet i virkelighetsnære scenarioer. Scenarioene inkluderer statiske og dynamiske hindringer, og tester er gjort både med og uten å ta hensyn til miljøfaktorer. Resultatene ser lovende ut. Anti-grunnstøtingssystemet forsikrer at AutoNauten unngår å bevege seg for nær land. Når det er flere ulike hindringer, tar systemet hensyn til både de statiske og de dynamiske hindringene, samtidig som den tar i betraktning de nåværende miljøfaktorene, og velger å utføre manøveren som fører med seg minst fare. Noen ganger innebærer dette at systemet ikke overholder COLREGS, men i stedet passer på at AutoNauten ikke går for nær land.Autonomous surface vehicles (ASVs) have an important role in the development of ocean observing systems (OOS) because they possess the ability to perform sustainable and continuous open ocean exploration and observation, even in harsh conditions in remote areas. These observations give knowledge about how the ocean and its dynamic processes are changing over time and how they are affected by climate changes. The AutoNaut is a wave-propelled green-energy ASV that is suited for these kinds of missions.
In order for an ASV to be able to operate autonomously on the ocean and along the coast, a robust collision and grounding avoidance system is crucial. The collision avoidance system needs to be compliant with the International Regulations for Preventing Collisions at Sea (COLREGS), and the anti-grounding system should be able to use data from electronic navigational charts (ENCs).
This thesis proposes an ENC-based anti-grounding system and integrates it into the existing simulation-based model predictive control (SB-MPC) collision avoidance system (CAS) developed by Johansen et al. [1] and implemented by Hagen [2], [3]. The system is adapted and implemented on the AutoNaut. The collision and grounding avoidance system is COLREGS compliant and can take environmental factors into account when evaluating which action to take in a given situation.
Several simulations are performed in order to test the system in real-life scenarios. The scenarios include static and dynamic obstacles and are done with and without environmental factors included. The results look promising. The anti-grounding system ensures that the AutoNaut avoids going too close to land. When there are multiple obstacles, the system is able to take both static and dynamic obstacles into consideration, at the same time as it accounts for the environmental conditions and chooses the least hazardous action in the situation. Sometimes, this means not complying with COLREGS in order to avoid going too close to land

Localities appearing in the published literature that are just outside this range and have yet to be confirmed are: North Carolina; E Florida (north of Palm Beach Co.); Alabama (Gulf coast); Louisiana; and Cuba (west and south of its NW coast). Reports of specimens from further afield are unlikely to be <i>C. thea</i>. Habitat reports are from the littoral zone to 27 m depths, from locations around sand bars of inside waters (Perry, 1940b: 165), in tide pools at low tide, bays, and from shallower waters offshore. Substrates range widely from mud flats, to sand and rubble bottoms in grass.</p> <p> <b> Description. <i>Shell</i></b> small (to 16.9 mm), narrowly to stoutly fusiform; truncate anteriorly, body whorl about 60% of length, and surface glossy; sculpture of axial ribs; whorls convex, suture impressed. <i>Protoconch</i> of approximately 1½–1¾ smooth, semi-translucent whorls, the first partially immersed in the second at its tip. <i>Axial sculpture</i> of well-spaced ribs, 7–9 on penultimate, 4–8 on last to varix, interspaces about twice their width, ribs run from suture-to-suture on spire whorls, evanesce early on shell base, straight to oblique, broadest and highest, sometimes knob-like, at shell periphery, lower, narrower, sometime obsolete on last whorl, and hooked to the left in sulcal area; rib profile convex, periphery below mid whorl on spire whorls; rib crests round at periphery and ridged on shoulder. Spiral sculpture limited to faint spiral ridges on shell base, below periphery, and distinct ridges on anterior fasciole. Sulcus obscure in some, marked by the presence of curved growth striae, to well-marked by reduced ribs, narrowed and curved, or obsolete ribs as in the later whorls of larger specimens. <i>Vari x</i> cup handlelike, ¼-turn from edge of outer lip. <i>Outer lip</i> thin, with a strengthening rib very close to lip edge in mature specimens; edge forming an arc from and congruent with anal sulcus to the stromboid notch; stromboid notch shallow. <i>Anal sulcus</i> deep, U-shaped, located on shoulder slightly set off from suture; sides of sinus divergent. <i>Inner lip</i> margined, thick along anterior canal, wider but thinner on parietal wall, and forming a lobe at junction with outer lip. <i>Anterior canal</i> very short, bent slightly to the right viewed ventrally, open and unnotched. <i>Color</i> light to dark caramel; usually rib crests just white, but sometimes a continuous mid-whorl white band present, and rarely a second, thin white band on shell base.</p> <p> <b> Remarks. <i>Nomenclatural.</i></b> Some references site the year of authorship of this name as 1883, but Dall’s description was published in 1884 (Jan), not 1883, as stated on the original publication (Rosenberg, 2009). <i> <i>Taxonomy.</i> Cerodrillia thea</i> is typical for <i>Cerodrillia</i> in possessing ribs from suture-to-suture, a cup-handle-like varix, and spiral sculpture limited to the shell base. <i>Cerodrillia thea</i> was included in <i>Cerodrillia</i> by Bartsch & Rehder (1939: 128–129) in their original description. Some specimens do exhibit characteristics of <i>Douglassia</i>, namely the significant reduction of ribs in the sulcus, even absent on the last whorls of older specimens. <i>Variability.</i> The average length of 68 specimens is 11.28 mm (5.3–16.9 mm), and their average W/L is 0.390. <i>C. thea</i> is narrow for <i>Cerodrillia</i>, most members of the genus have a W/L> 0.40. Individual specimens are uniformly colored, ranging from very dark brown to fairly light (Plate 35, Fig. 4). The color of the syntype depicted in Plate 34, Fig. 1 is typical of the species. Geographic variation is exhibited by this species and may be due to population isolation and habitat influences. Specimens from the Bahama Is. have more angular varices; those from the Florida Keys are smaller and darker, and from the central western coast of Florida are largest and generally colored like the types. <i> <i>Identification.</i> Cerodrillia thea</i> has a shell that is high-spired and uniformly light to dark caramel in color with lighter ribs that are noticeably oblique, traits that distinguish it from species with which it is often confused. <i>C. thea</i> is most similar to <i>C. harryleei</i>, new species and <i>C. sanibelensis</i>, new species, both from W Florida. From <i>C. harryleei</i> it differs in possessing slightly more ribs that are more oblique and less nodulose (7–9 versus 5–6 on the penultimate whorl). Also, <i>C. harryleei</i> has a faint brown spiral stripe in specimens examined so far, which is absent in <i>C. thea</i>. From <i>C. sanibelensis</i> it differs in possessing a narrower shell (average W/ L ratio = 0.390 versus 0.405), slightly more ribs that are more oblique (7–9 versus 6–7 on the penultimate whorl of individuals with varices), and darker color (light to dark caramel versus white to light orange brown).</p>Published as part of <i>Fallon, Phillip J., 2016, Taxonomic review of tropical western Atlantic shallow water Drilliidae (Mollusca: Gastropoda: Conoidea) including descriptions of 100 new species, pp. 1-363 in Zootaxa 4090 (1)</i> on pages 80-84, DOI: 10.11646/zootaxa.4090.1.1, <a href="http://zenodo.org/record/263299">http://zenodo.org/record/263299</a>
