    Dit artikel doet verslag van een beschrijvend onderzoek naar de burgerschapsdoelen die leraren in de beroepsgerichte vakken in de bovenbouw van het vmbo in hun lessen nastreven en de wijze waarop ze aan die doelen werken. Vijftien vakleraren, werkzaam in diverse sectoren werden geïnterviewd. De leraren zeggen weinig bezig te zijn met burgerschap als thema en doel. Tegelijkertijd besteden ze wel aandacht aan maatschappelijk verantwoord handelen en aan zelfkennis, vaardigheden en houdingen die te maken hebben met de relatie van de leerling tot anderen en de samenleving. In de context van het leren in levensechte beroepscontexten werken ze onder meer aan samenwerken, een goede werk- en beroepshouding en, met name in het geval van het technisch onderwijs, gezamenlijke zorg voor en reflectie op de kwaliteit van het werk. In de discussie gaan we in op de mogelijkheden voor een, in vergelijking tot algemene vormen van onderwijs, relatief eigen karakter van burgerschapsvorming in het vmbo en leggen een relatie met Sennetts visie op vakmanschap als burgerschap

    Citizenship in prevocational education: Professional pride as a source

    Get PDF
    The practice of citizenship education has predominantly been studied in general education. This article details an interview study of citizenship education of teachers in prevocational education in the Netherlands. We investigated whether and how vocational teachers reflected on their goals and teaching practices in citizenship education. Teachers did not perceive their teaching to be working on citizenship. However, they aimed at developing professional attitudes in their students, emphasising participation and ‘doing their work well’ in order to become respected and personally responsible workers/employees. In technical education, the development of pride in and shared responsibility for the quality of the students’ craftwork was emphasised. These findings are discussed in relation to Sennett’s views on the development of craftsmanship as citizenship. We see these views as strategic openings for an alternative to the dominant verbal, individualising and adaptation oriented approach of citizenship education

    Tachykinin receptors (version 2019.4) in the IUPHAR/BPS Guide to Pharmacology Database

    Get PDF
    Tachykinin receptors (provisional nomenclature as recommended by NC-IUPHAR [90]) are activated by the endogenous peptides substance P (SP), neurokinin A (NKA; previously known as substance K, neurokinin α, neuromedin L), neurokinin B (NKB; previously known as neurokinin β, neuromedin K), neuropeptide K and neuropeptide γ (N-terminally extended forms of neurokinin A). The neurokinins (A and B) are mammalian members of the tachykinin family, which includes peptides of mammalian and nonmammalian origin containing the consensus sequence: Phe-x-Gly-Leu-Met. Marked species differences in in vitro pharmacology exist for all three receptors, in the context of nonpeptide ligands. Antagonists such as aprepitant and fosaprepitant were approved by FDA and EMA, in combination with other antiemetic agents, for the prevention of nausea and vomiting associated with emetogenic cancer chemotherapy

    We present a detailed study of the critical properties of the 2-D XY model with maximal frustration in a square lattice. We use extensive Monte Carlo simulations to study the thermodynamics of the spin and chiral degrees of freedom, concentrating on their correlation functions. The gauge invariant spin-spin correlation functions are calculated close to the critical point for lattice sizes up to 240×240240\times 240; the chiral correlation functions are studied on lattices up to 96×9696\times 96. We find that the critical exponents of the spin phase transition are ν=0.3069\nu=0.3069, and η=0.1915\eta=0.1915, which are to be compared with the unfrustrated XY model exponents ν=1/2\nu=1/2 and η=0.25\eta=0.25. We also find that the critical exponents of the chiral transition are νχ=0.875\nu_{\chi}=0.875, 2β=0.19362\beta=0.1936, 2γ=1.822\gamma= 1.82, and 2γ=1.0252\gamma\>\prime=1.025, which are different from the expected 2-D Ising critical exponents. The spin-phase transition occurs at TU(1)=0.446T_{U(1)}=0.446 which is about 7\% above the estimated chiral critical temperature TZ2=0.4206T_{Z_{2}}= 0.4206. However, because of the size of the statistical errors, it is difficult to decide with certainty whether the transitions occur at the same or at slightly different temperatures. Finally, the jump in the helicity modulus in the fully frustrated system is found to be about 23\% below the unfrustrated universal value. The most important consequence of these results is that the fully frustrated XY model appears to be in a novel universality class. Recent successful comparisons of some of these results with experimental data are also briefly discussed. (TO APPEAR IN PRB)Comment: 47 pages (PHYZZX

    Dynamic ordering and frustration of confined vortex rows studied by mode-locking experiments

    Get PDF
    The flow properties of confined vortex matter driven through disordered mesoscopic channels are investigated by mode locking (ML) experiments. The observed ML effects allow to trace the evolution of both the structure and the number of confined rows and their match to the channel width as function of magnetic field. From a detailed analysis of the ML behavior for the case of 3-rows we obtain ({\it i}) the pinning frequency fpf_p, ({\it ii}) the onset frequency fcf_c for ML (\propto ordering velocity) and ({\it iii}) the fraction LML/LL_{ML}/L of coherently moving 3-row regions in the channel. The field dependence of these quantities shows that, at matching, where LMLL_{ML} is maximum, the pinning strength is small and the ordering velocity is low, while at mismatch, where LMLL_{ML} is small, both the pinning force and the ordering velocity are enhanced. Further, we find that fcfp2f_c \propto f_p^2, consistent with the dynamic ordering theory of Koshelev and Vinokur. The microscopic nature of the flow and the ordering phenomena will also be discussed.Comment: 10 pages, 7 figure, submitted to PRB. Discussion has been improved and a figure has been adde

    Outcomes of multimodal therapy in a large series of patients with anaplastic thyroid cancer

    Background The role of radiotherapy (RT) in the treatment of patients with anaplastic thyroid cancer (ATC) for local tumor control is critical because mortality often is secondary to complications of tumor volume rather than metastatic disease. Herein, the authors report the long-term outcomes of RT for patients with ATC. Methods A total of 104 patients with histologically confirmed ATC were identified who presented to the study institution between 1984 and 2017 and who received curative-intent or postoperative RT. Locoregional progression-free survival (LPFS), overall survival (OS), and distant metastasis-free survival were assessed. Results The median age of the patients was 63.5 years. The median follow-up was 5.9 months (interquartile range, 2.7-17.0 months) for the entire cohort and 10.6 months (interquartile range, 5.3-40.0 months) for surviving patients. Thirty-one patients (29.8%) had metastatic disease prior to the initiation of RT. Concurrent chemoradiation was administered in 99 patients (95.2%) and 53 patients (51.0%) received trimodal therapy. Systemic therapy included doxorubicin (73.7%), paclitaxel with or without pazopanib (24.3%), and other systemic agents (2.0%). The 1-year OS and LPFS rates were 34.4% and 74.4%, respectively. On multivariate analysis, RT >= 60 Gy was associated with improved LPFS (hazard ratio [HR], 0.135; P = .001) and improved OS (HR, 0.487; P = .004), and trimodal therapy was associated with improved LPFS (HR, 0.060; P = .017). The most commonly observed acute grade 3 adverse events included dermatitis (20%) and mucositis (13%), with no grade 4 subacute or late adverse events noted (adverse events were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events [version 4.0]). Conclusions RT appears to demonstrate a dose-dependent, persistent LPFS and OS benefit in patients with locally advanced ATC with an acceptable toxicity profile. Aggressive RT should be strongly considered for the treatment of patients with ATC as part of a trimodal treatment approach

    Quantum Interference in Superconducting Wire Networks and Josephson Junction Arrays: Analytical Approach based on Multiple-Loop Aharonov-Bohm Feynman Path-Integrals

    Get PDF
    We investigate analytically and numerically the mean-field superconducting-normal phase boundaries of two-dimensional superconducting wire networks and Josephson junction arrays immersed in a transverse magnetic field. The geometries we consider include square, honeycomb, triangular, and kagome' lattices. Our approach is based on an analytical study of multiple-loop Aharonov-Bohm effects: the quantum interference between different electron closed paths where each one of them encloses a net magnetic flux. Specifically, we compute exactly the sums of magnetic phase factors, i.e., the lattice path integrals, on all closed lattice paths of different lengths. A very large number, e.g., up to 108110^{81} for the square lattice, exact lattice path integrals are obtained. Analytic results of these lattice path integrals then enable us to obtain the resistive transition temperature as a continuous function of the field. In particular, we can analyze measurable effects on the superconducting transition temperature, Tc(B)T_c(B), as a function of the magnetic filed BB, originating from electron trajectories over loops of various lengths. In addition to systematically deriving previously observed features, and understanding the physical origin of the dips in Tc(B)T_c(B) as a result of multiple-loop quantum interference effects, we also find novel results. In particular, we explicitly derive the self-similarity in the phase diagram of square networks. Our approach allows us to analyze the complex structure present in the phase boundaries from the viewpoint of quantum interference effects due to the electron motion on the underlying lattices.Comment: 18 PRB-type pages, plus 8 large figure

    The Influence of Education and Socialization on Radicalization: An Exploration of Theoretical Presumptions and Empirical Research

    Get PDF
    Background and Objective: Research into radicalization does not pay much attention to education. This is remarkable and possibly misses an important influence on the process of radicalization. Therefore this article sets out to explore the relation between education on the one hand and the onset or prevention of radicalization on the other hand. Method: This article is a theoretical literature review. It has analyzed empirical studies-mainly from European countries-about the educational aims, content and style of Muslim parents and parents with (extreme) right-wing sympathies. Results: Research examining similarity in right-wing sympathies between parents and children yields mixed results, but studies among adolescents point to a significant concordance. Research also showed that authoritarian parenting may play a significant role. Similar research among Muslim families was not found. While raising children with distrust and an authoritarian style are prevalent, the impact on adolescents has not been investigated. The empirical literature we reviewed does not give sufficient evidence to conclude that democratic ideal in and an authoritative style of education are conducive to the development of a democratic attitude. Conclusion: There is a knowledge gap with regard to the influence of education on the onset or the prevention of radicalization. Schools and families are underappreciated sources of informal social control and social capital and therefore the gap should be closed. If there is a better understanding of the effect of education, policy as well as interventions can be developed to assist parents and teachers in preventing radicalization. © 2011 The Author(s)

    Altered orbitofrontal sulcogyral patterns in gambling disorder: a multicenter study

    Get PDF
    Gambling disorder is a serious psychiatric condition characterized by decision-making and reward processing impairments that are associated with dysfunctional brain activity in the orbitofrontal cortex (OFC). However, it remains unclear whether OFC functional abnormalities in gambling disorder are accompanied by structural abnormalities. We addressed this question by examining the organization of sulci and gyri in the OFC. This organization is in place very early and stable across life, such that OFC sulcogyral patterns (classified into Types I, II, and III) can be regarded as potential pre-morbid markers of pathological conditions. We gathered structural brain data from nine existing studies, reaching a total of 165 individuals with gambling disorder and 159 healthy controls. Our results, supported by both frequentist and Bayesian statistics, show that the distribution of OFC sulcogyral patterns is skewed in individuals with gambling disorder, with an increased prevalence of Type II pattern compared with healthy controls. Examination of gambling severity did not reveal any significant relationship between OFC sulcogyral patterns and disease severity. Altogether, our results provide evidence for a skewed distribution of OFC sulcogyral patterns in gambling disorder and suggest that pattern Type II might represent a pre-morbid structural brain marker of the disease. It will be important to investigate more closely the functional implications of these structural abnormalities in future work.Y.L. was supported by the National Natural Science Foundation of China (Grant No. 31600929) and the Fundamental Research Funds for the Central Universities (010914380002).
