Afro-Caribbean Immigrant Faculty Experiences in the American Academy: Voices of an Invisible Black Population

Afro-Caribbean immigrants have been an integral part of the history and shaping of the United States since the early 1900s. This current study explores the experiences of five Afro-Caribbean faculty members at traditionally White institutions of higher education. Despite the historical presence and influence of Afro-Caribbean communities and the efforts within education systems to address the needs of Afro-Caribbean constituents, Afro-Caribbean faculty members continue to be rendered indiscernible in higher education and to be frequently and erroneously perceived as African–Americans. The study examines the lived experiences of these individuals in the hegemonic White spaces they occupy at their institutions with both White and Black populations. Through their narratives, issues of stereotyping, microaggression, and isolation are addressed. The participants also offer solutions to address these issues by university administrators, department heads, faculty development professionals, diversity officers, policy makers, and other stakeholders. The voices in this study shed light on an overlooked, misunderstood, and under-researched population within our faculty ranks in the American Academy.     

Curriculum of Connection: What Does Sense8 Teach us About Love,Community and Responsibility in Days of Despair?

The TV show Sense8 tells the story of eight strangers from all around the world who realize they are connected to each other in a unique way. While taking their first steps of their quest to understand what bonds them and how they relate to one another, they are challenged by powerful people who want to capture them. Their individual journeys become a collective one, and through practicing a love ethic, they grow individually and collectively—an important lesson that can be taught in our classrooms. This article discusses what a love ethic entails and how it relates to restoring a sense of community within our schools and classrooms as a counteraction to neoliberal ideology and practices that harm our schools and atomize our communities.     

#Blackwomenatwork: Teaching and Retention in Urban Schools

Black female educators played a vital role in segregated schools prior to the 1954 landmark Supreme Court case Brown v. Board of Education of Topeka, Kansas. Despite their notable and historic presence in the field of public education, presently they are disproportionately underrepresented in the U.S. teacher workforce. Acknowledging the shortage of Black female teachers in K-12 classrooms, the purpose of this qualitative study is to explore why Black female educators teach in urban schools. By examining Black female educators’ initial draw to urban schools in what I conceptualized as the urban factor, I hope to reframe the implicit biases often surrounding urban schools. Concluding, three themes emerged about Black female teachers’ thoughts on and preferences for urban schools, with additional unexpected findings about their perceptions of student behavior and teacher retention.

An adaptive fuzzy filter for coding artifacts removal in video and image

This paper proposes a new adaptive post-filtering algorithm to remove coding artifacts in block-based video coder. The proposed method concentrates on blocking and ringing artifacts removal. For de-blocking, the blocking strength is identified to determine the filtering range, and the maximum quantization parameter of the image is used to adapt the 1D fuzzy filter. For de-ringing, besides the edge detection, a complementary ringing detection method is proposed to locate the neglected ringing blocks, and the gradient threshold is adopted to adjust the parameter of 2D fuzzy filter. Experiments are performed on the MPEG-4 sequences. Compared with other methods, the proposed one achieves better detail preservation and artifacts removal performance with lower computational cost.     

Simians in the Shape School: A comparative study of executive attention

Executive functions (EF) have been studied extensively in children and adults. However, EF tasks for young children can be difficult to administer and interpret. Espy (1997, Developmental Neuropsychology, 13, 495–499) designed the Shape School task to measure inhibition and switching in preschool-aged children. Shape School presents cartoon-like characters that children must flexibly name by their color, their shape, or both, depending on cues that indicate the appropriate rule. Shape School has been found to be age sensitive as well as predictive of performance on other EF tasks. We presented a computerized analogue of Shape School to seven rhesus macaques. Monkeys were trained to categorize characters by color or shape, or to inhibit this response, depending on whether the characters had eyes open, eyes closed, or wore hats. Monkeys performed above chance on the inhibition and switching components of the task. Long runs of a single classification rule and long runs of noninhibition trials had no significant impact on performance when the rule changed or inhibition was required. This nonverbal adaptation of Shape School can measure EF in nonhuman animals and could be used in conjunction with other EF tasks to provide a clearer picture of both human and nonhuman executive functions.

Effects of glucose and gibberellic acid on glucosinolate content and antioxidant properties of Chinese kale sprouts

Glucosinolates, anthocyanins, total phenols, and vitamin C, as well as antioxidant capacity, were investigated in Chinese kale sprouts treated with both glucose and gibberellic acid (GA₃). The combination of 3% (0.03 g/ml) glucose and 5 μol/L GA₃ treatment was effective in increasing glucosinolate content while glucose or GA3 treatment alone did not influence significantly almost all individual glucosinolates or total glucosinolates. The total phenolic content and antioxidant activity of Chinese kale sprouts were enhanced by combined treatment with glucose and GA₃, which could be useful in improving the main health-promoting compounds and antioxidant activity in Chinese kale sprouts.     

Der Mathematikunterricht der PISA-Schülerinnen und -Schüler

Der Beitrag besch?ftigt sich mit dem Mathematikunterricht der PISA-Schülerinnen und -Schüler in Deutschland und berichtet über Ergebnisse aus einer Zusatzstudie zu PISA 2003. Aufbauend auf der mathematik-didaktischen Rahmenkonzeption von PISA, die Unterricht als Gelegenheitsstruktur für verst?ndnisvolle Lernprozesse versteht, wurden Schülerinnen und Schüler und ihre Mathematiklehrkr?fte zu Merkmalen der Unterrichtsqualit?t befragt. Es zeigen sich schulformspezifische Unterrichtskulturen: Ein kognitiv aktivierender Umgang mit mathematischen Inhalten ist eher in Gymnasien zu beobachten, w?hrend vor allem in Hauptschulen die Unterrichtsform mit geringem kognitiven Gehalt und ausgepr?gter Unterstützung überwiegt. Dennoch wird die Angebotsstruktur des Mathematikunterrichts von Jugendlichen an Hauptschulen positiv beurteilt, w?hrend Gymnasiasten ihren Unterricht eher kritisch bewerten. Diese Differenzen sind vor allem durch Unterschiede in der individuellen Lernunterstützung durch die Lehrkr?fte zu erkl?ren, welche von Schülerinnen und Schülern an Hauptschulen als besonders ausgepr?gt, an Gymnasien eher als gering beschrieben wird.
