The Dynamic Integrated Approach to teacher professional development: rationale and main characteristics

This paper refers to the Dynamic Integrated Approach towards teacher professional development which attempts to merge research findings on teacher effectiveness and teacher professional development. The theoretical framework and the major features of the DIA are presented. It is argued that the DIA can be effectively implemented through five steps: Establishing clarity and consensus about aims and objectives, identifying needs and priorities for improvement through empirical investigation, provision of improvement guidelines, reflection opportunities and coaching on effective teaching by the advisory and research team, establishing a formative evaluation mechanism and finally establishing a summative evaluation system. Results of empirical studies providing support to the basic elements and the overall effectiveness of the DIA are also presented. Implications of the findings are discussed and suggestions for further research, particularly in exploring the conditions under which the DIA could have a long lasting effect on teacher effectiveness, are finally drawn.This is the author accepted manuscript.

Conducting language production research online: A web-based study of semantic context and name agreement effects in multi-word production

Few web-based experiments have explored spoken language production, perhaps due to concerns of data quality, especially for measuring onset latencies. The present study highlights how speech production research can be done outside of the laboratory by measuring utterance durations and speech fluency in a multiple-object naming task when examining two effects related to lexical selection: semantic context and name agreement. A web-based modified blocked-cyclic naming paradigm was created, in which participants named a total of sixteen simultaneously presented pictures on each trial. The pictures were either four tokens from the same semantic category (homogeneous context), or four tokens from different semantic categories (heterogeneous context). Name agreement of the pictures was varied orthogonally (high, low). In addition to onset latency, five dependent variables were measured to index naming performance: accuracy, utterance duration, total pause time, the number of chunks (word groups pronounced without intervening pauses), and first chunk length. Bayesian analyses showed effects of semantic context and name agreement for some of the dependent measures, but no interaction. We discuss the methodological implications of the current study and make best practice recommendations for spoken language production research in an online environment

The impact of school policy and stakeholders' actions on student learning: A longitudinal study

This paper proposes and validates a theoretical framework on how school policy can promote student learning. School policy is considered to have an indirect effect on student achievement by changing school stakeholders’ actions toward improving the School Learning Environment (SLE) and teaching practice. A reciprocal relationship between school policy and stakeholders’ actions is also considered. A longitudinal study was conducted to test the framework’s main assumptions. A stratified sample of 64 primary schools was selected and students’ achievement in Mathematics at the beginning of Grade 4 and at the end of the next three consecutive school years was measured, alongside the school policy and teachers’ actions with regards to issues associated with teaching and the SLE. The results of Multilevel structural equation modelling analyses supported the main assumptions of the framework. Implications for the development of school policy are drawn and suggestions for further research are provided.This is the author accepted manuscript.

Resilience, well-being and informal and formal support in multi-problem families during the Covid-19 pandemic

BACKGROUND: The Covid-19 pandemic may have had negative effects on youth and parental mental health, especially in high-risk populations such as multi-problem families (i.e., families that experience problems in multiple domains, such as mental health and social network problems). Using one to four assessments during all phases of the Covid-19 pandemic up until January 2022, we examined the associations between pandemic-related stress and mental health (resilience and well-being) of youth and parents from multi-problem families. We also investigated whether experienced informal (i.e., youth informal mentoring) and formal support (i.e., therapist support) served as protective factors in this association. METHODS: A total of 92 youth aged 10–19 years (46.7% girls; mean age 16.00 years) and 78 parents (79.5% female; mean age 47.17 years) filled in one to four questionnaires between March 2020 and January 2022. Multi-level analyses were conducted to account for the nested structure of the data. RESULTS: For youth, pandemic-related stress was associated with lower well-being, but not with resilience. Perceived support from both mentors and therapists was positively associated with youth mental health. Furthermore, high perceived therapist support protected youth from the negative effect of pandemic-related stress on resilience. For parents, pandemic-related stress was not related to mental health, irrespective of therapist support. Yet, therapist support was directly and positively associated with parental mental health. CONCLUSIONS: Youth from multi-problem families who experience pandemic-related stress are at risk of (elevated) mental health problems during the pandemic, specifically if they have no or weak therapist support. The mental health of parents, however, was minimally affected by pandemic-related stress, indicating strength and flexibility. Youth and parents who experienced support during the pandemic reported higher levels of resilience and well-being, demonstrating the importance of support for individuals’ mental health during stressful times such as a pandemic.

Het recht van de eigenaar om de bestemming van de gond "zelf" te realiseren

In deze scriptie wordt nagegaan welke ruimte de Kroon en de rechter geven voor zelfrealisering in het kader van enerzijds de Onteigeningswet en anderzijds de Wet voorkeursrecht gemeenten. Daarbij worden de onderlinge verschillen in beeld gebracht en wordt nagegaan of afstemming mogelijk is. Tevens wordt aangegeven welke wijzigingen op het punt van het zelfrealisatierecht te verwachten zijn in verband met de invoering in 2008 van de nieuwe Wet ruimtelijke ordening en de daarin opgenomen Grondexploitatiewet. Tenslotte wordt aandacht besteed aan de achtergronden van het recht op zelfrealisatie en de relatie met het aanbestedingsrecht

Class 3 semaphorins expression and association with innervation and angiogenesis within the degenerate human intervertebral disc

Nerve and blood vessel ingrowth during intervertebral disc degeneration, is thought to be a major cause of low back pain, however the regulation of this process is poorly understood. Here, we investigated the expression and regulation of a subclass of axonal guidance molecules known as the class 3 semaphorins, and their receptors; plexins and neuropilins within human NP tissue and their regulation by pro-inflammatory cytokines. Importantly this determined whether semaphorin expression was associated with the presence of nerves and blood vessels in tissues from human intervertebral discs. The study demonstrated that semaphorin3A, 3C, 3D, 3E and 3F and their receptors were expressed by native NP cells and further demonstrated their expression was regulated by IL-1β but to a lesser extent by IL-6 and TNFα. This is the first study to identify sema3C, sema3D and their receptors within the nucleus pulposus of intervertebral discs. Immunopositivity shows significant increases in semaphorin3C, 3D and their receptor neuropilin-2 in degenerate samples which were shown to contain nerves and blood vessels, compared to non-degenerate samples without nerves and blood vessels. Therefore data presented here suggests that semaphorin3C may have a role in promoting innervation and vascularisation during degeneration, which may go on to cause low back pain
