SYMPOSIUM: THE SUPREME COURT''S MICHIGAN DECISIONS

On 23 June 2003, the Supreme Court of the United States issued two rulings on the constitutionality of race preferences in university admissions. The cases in question both involved the University of Michigan and were designated Gratz v. Bollinger and Grutter v. Bollinger. Academic Questions' editors subsequently invited five scholars to address the meaning and significance of those decisions.     

Hybrid heuristic and mathematical programming in oil pipelines networks： Use of immigrants

We solve the problem of petroleum products distribution through oil pipelines networks. This problem is modelled and solved using two techniques: A heuristic method like a multiobjective evolutionary algorithm and Mathematical Programming. In the multiobjective evolutionary algorithm, several objective functions are defined to express the goals of the solutions as well as the preferences among them. Some constraints are included as hard objective functions and some are evaluated through a …     

Students as political actors? Similarities and differences across six European nations

Drawing on data from students, higher education staff and policymakers from six European countries, this article argues that it remains a relatively common assumption that students should be politically engaged. However, while students articulated a strong interest in a wide range of political issues, those working in higher education and influencing higher education policy tended to believe that students were considerably less politically active than their predecessors. Moreover, while staff and policy influencers typically conceived of political engagement in terms of collective action, articulated through common reference to the absence of a ‘student movement’ or unified student voice, students’ narratives tended not to valorise ‘student movements’ in the same way and many categorised as ‘political’ action they had taken alone and/or with a small number of other students. Alongside these broad commonalities across Europe, the article also evidences some key differences between nation-states, institutions and disciplines. In this way, it contributes to the comparative literature on young people’s political engagement specifically, as well as wider debates about the ways in which higher education students are understood.     

Teachers’ Emotion Minimizing Language and Toddlers’ Social Emotional Competence

Teachers in toddler classrooms are important agents of emotion socialization. The current study examined teachers’ use of emotion minimizing language in toddler classrooms and toddlers’ social emotional competence. Teachers’ emotion minimizing language is described as language that purposefully distances them from a child’s emotions and discourages children’s expression of their emotions. Research Findings: Results indicate a negative relationship between teachers’ emotion minimizing language and toddlers’ social emotional competence when program quality, child age, and child gender are controlled. Practice or Policy: Implications relevant to teacher preparation programs and professional development are discussed, with a primary focus on the methods by which teachers are trained to use language to respond to young children’s emotions.     

Assessing Quality in Toddler Classrooms Using the CLASS-Toddler and the ITERS-R

Many very young children attend early care and education programs, but current information about the quality of center-based care for toddlers is scarce. Using 2 observation instruments, the Infant/Toddler Environment Rating Scale–Revised (ITERS-R) and the Classroom Assessment Scoring System, Toddler Version (CLASS-Toddler), 93 child care classrooms for toddlers across the state of North Carolina, representing a range of quality, were assessed to determine overall quality, and associations between observed quality and teachers' ratings of child behavior problems and competence outcomes using the Brief Infant Toddler Social Emotional Assessment. Research Findings: Findings indicated that overall, toddler classrooms were rated as being of moderate quality. Associations between observed quality and teacher-reported child behavior problems and competence outcomes indicated that CLASS-Toddler ratings were positively associated with fewer behavior problems; specifically, children in classrooms with higher levels on the CLASS-Toddler domains of Emotional and Behavioral Support as well as Engaged Support for Learning were reported to have fewer behavior problems. Similarly, the ITERS-R subscales of Interaction and Listening and Talking were positively related to fewer reported behavior problems. Regression models showed that the CLASS-Toddler Emotional and Behavioral Support domain predicted differences in child behavior problems. Practice or Policy: Findings suggest the need for additional research related to very young children's experiences in center-based child care to examine associations between quality and child experiences and outcomes. Children's experiences over time need to be examined to understand how these early child care experiences are related to children's later school adjustment and performance. On a related note, professional development for teachers in toddler classrooms needs to be addressed in terms of preparing effective teachers for young children during the toddler developmental period.     

Examining Differences in Students’ Beliefs and Attitudes: An Important Element of Performance-Based Assessment Systems for Teacher Preparation Programs

The National Council for Accreditation of Teacher Education (NCATE) program review process increasingly emphasizes the importance of performance-based assessment of early childhood teacher preparation programs. As part of the effort to address performance-based assessment requirements, the teacher educator program described in this study examined students’ beliefs related to developmentally appropriate practice, attitudes toward children, and perceived competencies at different points in the program and upon graduation. One hundred eighteen students and 78 recent graduates participated. Results suggest that students’ beliefs are more consistent with developmentally appropriate practices and with a progressive or child-centered approach at later points in the program. In general, participants felt they were more competent in what they know about early childhood practices than in how they implement the practices. Students nearing completion of the program and those who had graduated reported that they knew more about early childhood practices than students enrolled in early courses in the program, and graduates felt they were more competent to implement early childhood practices than students not enrolled in the program. Results are discussed in terms of implications for examining teacher preparation programs.     

Education and colonial language policies in Latin America and the Caribbean

In Latin America governmental responses to the language issue have ranged from suppression of non-European languages to active promotion of at least a limited bilingualism. The thesis of this article is that the inconsistencies are primarily a function of economic and social struggles among contending national elites with the common goal of compelling subordinate groups to adapt to the behaviors and expectations of the elite groups. Not until the nineteenth century witnessed a shift to capital-intensive modes of production did the schools become a major locus for implementation of governmental policy. Then the schools were called upon in a direct and massive way to augment traditional forms of social control.

Zusammenfassung In Latein-Amerika reichte die Reaktion der Regierungen auf sprachliche Probleme von der Unterdrückung nicht-europäischer Sprachen bis zur aktiven Förderung wenigstens einer begrenzten Zweisprachigkeit. Dieser Artikel vertritt den Standpunkt, die Gegensätze seien hauptsächlich bedingt durch wirtschaftliche und soziale Kämpfe zwischen wetteifernden nationalen Führungsschichten, die alle das gleiche Ziel verfolgen, untergeordnete Gruppen zu zwingen, die Verhaltensweisen und Erwartungen der Führungsgruppen zu übernehmen. Erst als sich das 19. Jahrhundert allmählich auf kapital-intensive Produktionsweisen umstellte, wurden die Schulen in höherem Masse Zuchtstätten der Regierungspolitik. Danach wurden sie unmittelbar und massiv aufgerufen, traditionelle Formen der Gesellschaftskontrolle zu verstärken.

Résumé En Amérique Latine les réponses gouvernementales à la question du langage sont passées d'une suppression des langages non-européens à leur promotion active, ou du moins à un certain bilingualisme. La thèse de cet article est que ces inconséquences sont avant tout fonction des luttes économiques et sociales entre les élites nationales en présence dont le but commun est de contraindre les groupes subordonnés à s'adapter à leurs manières d'être et à leurs expectations. Ce n'est qu'après que le dixneuvième siècle ait été le témoin d'un glissement vers des méthodes de production à haute teneur en capitaux que les écoles sont devenues le locus principal de mise en oeuvre de la politique gouvernementale. On a eu, alors, recours aux écoles d'une façon directe et massive pour augmenter les formes traditionnelles de contrôle social.

     

Assessment Focus in Studio: What is Most Prominent in Architecture,Art and Design?

What can be learned about assessment from what educators in the creative practices focus their studio publications on? What should form the focus of assessment in architecture, art and design studios? In this article we draw on 118 journal articles on studio published over the last decade in three disciplines; architecture, art and design to inform the focus of studio assessment. We believe that what is published by educators themselves in these disciplines reveals what matters most to them. In addition, we argue that regardless of the primary emphasis placed in each discipline, assessment in studio should encompass a broad set of indicators. Within the wider literature including in architecture, art and design, a view of assessment is emerging that recognises the process and the person, beyond a view that positions the product or art/design arte‐fact above all else. Therefore, drawing on what educators in architecture, art and design mentioned most in the journal publications analysed, as well as the literature on good assessment, we offer a holistic model to guide and take studio assessment in the creative disciplines further.

Dominant edge direction based fast intra mode decision in the H.264/AVC encoder

The H.264/AVC video coding standard uses an intra prediction mode with 4×4 and 16×16 blocks for luma and 8×8 blocks for chroma. This standard uses the rate distortion optimization （RDO） method to determine the best coding mode based on the compression performance and video quality. This method offers a large improvement in coding efficiency compared to other compression standards, but the computational complexity is greater due to the various intra prediction modes. This paper proposes a fast intra mode decision algorithm for real-time encoding of H.264/AVC based on the dominant edge direction （DED）. The DED is extracted using pixel value summation and subtraction in the horizontal and vertical directions. By using the DED, three modes instead of nine are chosen for RDO calculation to decide on the best mode in the 4×4 luma block. For the 16×16 luma and the 8 × 8 chroma, only two modes are chosen instead of four. Experimental results show that the entire encoding time saving of the proposed algorithm is about 67% compared to the full intra search method with negligible loss of quality.
