Maintaining and Improving Academic Achievement in the Midst of Significant Demographic Change: A Case Study Analysis
The research of Mei Jiun Wu (2013) indicates that demographic change greater than 1% has significant impact on the achievement performance of school districts. This study analyzes a single district that experienced an average of 1.25% demographic change per year consisting of an increase of non-White students from 2002 to 2015. Despite this compounding change, the district was able to maintain and improve academic achievement. This study utilizes Marzano and Waters\u27 (2009) framework for school leadership as well as Lindsey, Nuri-Robins, and Terrell\u27s (2009) Framework for cultural proficiency to better understand how the district was able to maintain and improve academic achievement in the midst of significant demographic change. The study identifies the educational practices suggested by these frameworks as active within the school district and highlights the positive impact of mission oriented collaborative goal setting, data driven needs assessment with corresponding intervention services, overlapping communication structures, and a communal expectation of culturally responsive behavior
School Discipline of Cyber-Bullies: A Proposed Threshold That Respects Constitutional Rights, 45 J. Marshall L. Rev. 85 (2011)
Phytophthora hotspots in het zetmeelaardappelgebied
In Agrobiokon is een eerste verkenning van regionale aspecten van de epidemiologie van de aardappelziekte uitgevoerd met een analyse naar het optreden van hotspots: plaatsen die bij herhaling geassocieerd worden met het optreden van primaire inoculumbronnen en die daarom extra aandacht in een bestrijdingsstrategie vragen. Uit het onderzoek is gebleken dat er geen sterke aanwijzingen zijn dat hotspots een belangrijke rol spelen in de (regionale) epidemiologie van de aardappelziekte in het zetmeelaardappelgebied
Effects of sublethal single, simultaneous and sequential abiotic stresses on phenotypic traits of Arabidopsis thaliana
Plant responses to abiotic stresses are complex and dynamic, and involve changes in different traits, either as the direct consequence of the stress, or as an active acclimatory response. Abiotic stresses frequently occur simultaneously or in succession, rather than in isolation. Despite this, most studies have focused on a single stress and single or few plant traits. To address this gap, our study comprehensively and categorically quantified the individual and combined effects of three major abiotic stresses associated with climate change (flooding, progressive drought and high temperature) on 12 phenotypic traits related to morphology, development, growth and fitness, at different developmental stages in four Arabidopsis thaliana accessions. Combined sublethal stresses were applied either simultaneously (high temperature and drought) or sequentially (flooding followed by drought). In total, we analysed the phenotypic responses of 1782 individuals across these stresses and different developmental stages. Overall, abiotic stresses and their combinations resulted in distinct patterns of effects across the traits analysed, with both quantitative and qualitative differences across accessions. Stress combinations had additive effects on some traits, whereas clear positive and negative interactions were observed for other traits: 9 out of 12 traits for high temperature and drought, 6 out of 12 traits for post-submergence and drought showed significant interactions. In many cases where the stresses interacted, the strength of interactions varied across accessions. Hence, our results indicated a general pattern of response in most phenotypic traits to the different stresses and stress combinations, but it also indicated a natural genetic variation in the strength of these responses. This includes novel results regarding the lack of a response to drought after submergence and a decoupling between leaf number and flowering time after submergence. Overall, our study provides a rich characterization of trait responses of Arabidopsis plants to sublethal abiotic stresses at the phenotypic level and can serve as starting point for further in-depth physiological research and plant modelling efforts

High-Income Child Support Guidelines: Harmonizing the Need for Limits with the Best Interests of the Child
Providing for the needs of children of separated parents lies at the heart of state child support laws. But what about providing for the special needs of children of high-income obligors and ensuring consistency in a system often marked by unpredictability and high emotions? This Note examines the manifold problems that discretionary high-income child support decisions can cause: inequitable settlement, increased litigation, injured family structures, and inconsistent decisions. This Note also proposes a solution: to set higher thresholds for triggering a high-income analysis and to require high-income parents to contribute to post-secondary educational trusts. Finally, this Note explains that, as a result of disparate parental resources and fixed costs concerns, the solution should also apply to parents who share physical custody of their children

Understanding MARC: Another Look
ç„¡<br>MARC format has been widely used and discussed in our profession. However, there appear to have a wide spread misunderstanding of its real structure and attributes. This article discuss the needs for us to understand it a little more. Also, it presents the general misconceptions about MARC, the compatibility of MARC, the structure of MARC, standardization and - data communication, and some major issues related to MARC format. In this library automation age, MARC is a key element in library services, and it deserves us to take another look
