Reproducing inequality through ambivalence, ignorance, and innocence – Revisiting practices of equality and human rights in Finnish teacher education

ABSTRACT Finland has repeatedly been presented as a “success story” of equality and education, promoter of human rights and included equality and human rights as part of national curricula. However, research has shown the slow progress of integrating topics of equality and human rights in teacher education despite hundreds of project-based interventions during the past 50 years. We used historically informed discursive reading drawing from the existent literature, human rights and equality policy documents, and data from student teachers (n = 311) about their perceptions. The theoretical framework in this article is grounded in critical and feminist theories. The aim is to analyse why student teachers still report receiving too little education in human rights and equality despite the improvements in human rights and equality education law and policy. We argue that Finnish teacher education has an ambivalent role of representing itself as “exceptional” while reproducing inequalities. Furthermore, this alleged “exceptionalism” does not enable a focus on equality and human rights policies goals. We constructed a general theoretical frame to re-examine critically the role of ambivalence, ignorance, and “innocence”, which reproduce inequalities. Our analysis describes several discursive realities of public narratives and student teachers’ experiences concerning equality and human rights education. This article provides a novel interpretation frame for the persisting inequalities in education in a country that profiles itself as a champion of human rights and equality. Based on our results, we suggest critical self-reflection for educational policy to advance continuous measures to affect structural inequalities.
Comparative study of wavelet methods in ground vehicle signature analysis

In this paper we make a comparison between wavelet transforms and the local cosine transform of various types of images. This builds on our previous work involving acoustic signals, where we found that the local cosine transform gave a more compact representation for certain types of signals and performed as well as wavelets for others. This held even for signals that were transient in nature, where one might expect the wavelets to do better. We are interested in determining if the same holds true for images, which tend to include many transients, such as edges. We are also investigating the extent to which the rms error can be used to evaluate the perceptual quality of the reconstructed images.
Effects of dietary supplementation of Amla, Chicory and Leek extracts on growth performance, immunity and blood biochemical parameters of broilers

Abstract The need for solutions to relieve heat stress and its undesirable effects on broiler production increased, especially in hot climatic areas. The antioxidant and immune stimulant effects of herbal extracts of Emblica officinalis (Amla), Cichorium intybus (Chicory) and Allium porrum (Leek) were examined against the adverse effects of heat stress in broilers. One thousand Cobb 500 one-day-old chicks were used for this experiment. Birds were divided into four equal groups. The first served as the control group. The second received Amla extract (3 g/kg diet), the third received Chicory extract (3 g/kg diet) and the last group received Leek extracts (3 g/kg diet). All groups were daily subjected to heat stress for 12 h by increasing house temperature to 8 ± 2 °C (10:00 am to 10:00 pm daily) using an electric heater, while relative humidity was kept at 47 ± 3%. Results revealed significant improvement in final body weight in treated groups, especially the Chicory and Amla-fed groups. Total weight gain was improved by dietary supplementation with herbal extracts, while feed intake, feed conversion ratio (FCR) and mortality percentage were reduced. The positive impact of the herbal extracts was also clear on carcase traits in the treated groups. Meat and serum lipids were significantly reduced in treated groups. White blood cells, phagocytic index and antioxidant enzyme levels were positively improved by dietary supplementations. In conclusion, using Amla, Chicory and Leek extracts positively improved broilers’ growth performance, immunity and oxidative stress status under heat stress conditions. Highlights Heat stress causes huge economic losses in livestock production worldwide. Herbal extracts are rich in antioxidants at low prices than other feed additives. Herbal extracts can enhance the defense system and reduce the negative effects of heat stress.
School-Class Co-Ethnic and Immigrant Density and Current Smoking among Immigrant Adolescents

Although the school-class is known to be an important setting for adolescent risk behavior, little is known about how the ethnic composition of a school-class impacts substance use among pupils with a migration background. Moreover, the few existing studies do not distinguish between co-ethnic density (i.e., the share of immigrants belonging to one’s own ethnic group) and immigrant density (the share of all immigrants). This is all the more surprising since a high co-ethnic density can be expected to protect against substance use by increasing levels of social support and decreasing acculturative stress, whereas a high immigrant density can be expected to do the opposite by facilitating inter-ethnic conflict and identity threat. This study analyses how co-ethnic density and immigrant density are correlated with smoking among pupils of Portuguese origin in Luxembourg. A multi-level analysis is used to analyze data from the Luxembourg Health Behavior in School-Aged Children study (N = 4268 pupils from 283 classes). High levels of co-ethnic density reduced current smoking. In contrast, high levels of immigrant density increased it. Thus, in research on the health of migrants, the distinction between co-ethnic density and immigrant density should be taken into account, as both may have opposite effects.
350.9 nm UV Laser Diode Grown on Low-Dislocation-Density AlGaN

We demonstrated a UV-laser diode grown on low-dislocation-density AlGaN. The combination of a low-temperature-deposited AlN interlayer technology and heteroepitaxial lateral overgrowth yielded crack-free and partially low-dislocation-density AlGaN on a grooved GaN substrate. A ridge waveguide was fabricated in the low-dislocation-density region. The lasing wavelength under pulsed current injection at room temperature was 350.9 nm, which is the shortest wavelength ever reported.
The intrinsic shape of NGC 3379

Photometric and kinematic data from the literature are combined with new dynamical models to derive the intrinsic shape of the 'standard' elliptical galaxy NGC 3379. The parameters that are best constrained are the dynamical triaxiality T (essentially the triaxiality of the total mass distribution) and the short-to long axis ratio of the light distribution c(sub L). The inferred shape is given by a Bayesian probability distribution in the (T, c(sub L) plane. Assuming a uniform prior, the most probable shape is oblate with a flattening of c(sub L) = 87. The distribution is strongly non-Gaussian, however, and the expectation values, (T) = . 31 (c(sub L) = . 75, imply a flatter and more triaxial figure. The 68% highest posterior density region allows more triaxial shapes as long as they are fairly round, or flatter shapes as long as they are nearly oblate. These results are essentially unchanged if the galaxy is assumed to rotate about its short axis, or if it is modeled as an S0 with a negligible-mass disk rather than as an elliptical. The suggestion of Capaccioli et al. (ApJ, 371, 535 (1991)) that NGC 3379 is a rather flat, triaxial S0 galaxy is found to be improbable at the 98% level; this conclusion is largely independent of the bulge-to-disk ratio or the relative rotation speeds of the two components.
No Sufficient Evidence for an Immediate Hypoalgesic Effect of Spinal Manual Therapy on Pressure Pain Thresholds in Asymptomatic and Chronic Pain Populations: A Systematic Review and Meta-Analysis.

OBJECTIVE Spinal manual therapy (SMT) is often used to treat patients with spinal disorders; however, the underlying mechanisms of SMT are not fully understood. This systematic review and meta-analysis investigates the effect of SMT compared with sham treatment or no intervention on local or remote (segmental or non-segmental) pressure pain thresholds (PPTs) in patients with chronic musculoskeletal conditions and people who are pain free. METHODS A systematic search was conducted in the PubMed, Cochrane Library, Web of Science, and CINAHL databases. Randomized controlled trials investigating the effect of SMT on PPTs in patients with chronic musculoskeletal conditions and in people who were pain free were included. Quality assessment and evidence synthesis were performed according to Cochrane Handbook recommendations. A meta-analysis was performed using standardized mean difference and 95% CIs. RESULTS Twenty-two reports were included in the present review. There were no significant results for an immediate effect of SMT on local (low certainty of evidence), remote (segmental) (low certainty of evidence), and remote (non-segmental) (low certainty of evidence) PPTs in patients with chronic pain as well as on local (moderate certainty of evidence) and remote (segmental) (low certainty of evidence) PPTs in people who were pain free. A small but significant effect (standardized mean difference = 0.26; 95% CI = 0.01 to 0.51; low certainty of evidence) was observed on remote (non-segmental) PPTs in people who were pain free, which was not considered a meaningful effect size. CONCLUSION No immediate, consistent, or meaningful hypoalgetic effect of SMT was shown on PPTs on various body areas. Involvement of spinal or supraspinal underlying mechanisms were, therefore, not confirmed via PPTs but should still be investigated using methods designed to assess central nervous pain processing. IMPACT No consistent and meaningful hypoalgesic effects of spinal manual therapy were demonstrated on PPTs in participants who were pain free and in patients with chronic musculoskeletal disorders.
Norm estimates relating polynomials and their derivatives

Inequalities bounding Lp (p > 0) norms of a polynomial by suitable norms of the derivative of the polynomial and an auxiliary function are obtained for the classes of polynomials whose zeros lie on the unit circumference or in the interior or the exterior of the unit disk. All the inequalities are best possible and generalize several known estimates in particular cases.
Clinical Stakes of Sexual Abuse in Adolescent Psychiatry

Background: The extent and nature of sexual abuse (SA) and its consequences in psychiatry are still poorly described in adolescence. Objective: This article describes the frequency of SA reported in an adolescent population hospitalized in psychiatry, and assesses its links with the severity of mental disorders and the medical issues of these adolescents. Methods: The study includes 100 patients for whom SA has been mentioned, among all patients aged 13 to 17 years old hospitalized for about 4 years. The characteristics of sexual abuse were correlated with the medical severity of the patients, as well as the number, the duration of their hospitalization(s), and the time until disclosure. Results: The results show the central place of SA in adolescent psychiatry, with a prevalence of 28.5% and a cumulative hospital stay which is five times longer than average. Correlations have been observed between the number of suicide attempts and the number of abuses reported. The medical severity of patients is significantly increased when the named aggressor is an adult. The number of hospitalizations is positively correlated with the number of reported abuses, as well as with the intrafamilial and adult status of the perpetrator. Finally, an early age of onset, repeated abuse, and the intrafamilial nature of the abuse are associated with a longer time to disclosure. Conclusions: The severity of adolescent psychiatric situation is statistically in favor of a history of SA, which should therefore be actively explored during care.
Calculation of Landé g factors for III-V nanowhisker quantum dots and comparison with experiment

The coupling between a magnetic field and the spin of an electron confined to a quantum dot is determined by the g factor, which is strongly affected by the structure of the dot. Uncertainties in a dot’s geometry and composition can obscure quantitative comparison of theory and experiment. Nanowhisker quantum dots NWQDs provide a well-controlled structure that is ideal for such comparison. We have performed detailed three-dimensional numerical calculations of the electronic properties of NWQDs consisting of an InP/ InAs/ InP quantum well embedded in a 111 oriented InAs nanowhisker. We have computed g factors, confinement energies, and wave functions for valence and conduction states as a function of dot size. The calculations are in excellent agreement with experiments and differ markedly from g factors obtained from extrapolation of bulk formulas, providing strong confirmation of the effect of angular momentum quenching. The closeness of our results to experiment enables us to identify critical well and barrier widths yielding g 0, which are important for technological applications. We also predict larger and more negative g factors for
Neurocognitive Endophenotypes for Eating Disorders: A Preliminary High-Risk Family Study

Eating disorders (EDs) are psychiatric disorders with a neurobiological basis. ED-specific neuropsychological and brain characteristics have been identified, but often in individuals in the acute phase or recovered from EDs, precluding an understanding of whether they are correlates and scars of EDs vs. predisposing factors. Although familial high-risk (FHR) studies are available across other disorders, this study design has not been used in EDs. We carried out the first FMH study in EDs, investigating healthy offspring of women with EDs and controls. We preliminarily aimed to investigate ED-related neurocognitive and brain markers that could point to predisposing factors for ED. Sixteen girls at FHR for EDs and twenty control girls (age range: 8–15), completed neuropsychological tests assessing executive functions. Girls also underwent a resting-state fMRI scan to quantify functional connectivity (FC) within resting-state networks. Girls at FHR for EDs performed worse on a cognitive flexibility task compared with controls (F = 5.53, p = 0.02). Moreover, they showed different FC compared with controls in several resting-state networks (p < 0.05 FDR-corrected). Differences identified in cognitive flexibility and in FC are in line with those identified in individuals with EDs, strongly pointing to a role as potential endophenotypes of EDs.
Voyager spectra of density turbulence from 1 AU to the outer heliosphere

[1] Power spectral analyses of the plasma density measured by the Voyager 2 spacecraft are used to investigate the spectral characteristics and fluctuation level of density turbulence from 1 to 60 AU, corresponding to the period 1977 to 1999. Only periods without clear discontinuities, with less than 10% missing data, and at least 256 samples are selected, strongly limiting the number and coverage of intervals analyzed. Typically, the power spectra have a dual power law form, with a closely Kolmogorov component at higher frequencies and a steeper component (∝ f−2) at lower frequencies, consistent with observations inside 1 AU. The spectral indices remain approximately constant with heliocentric distance R ≲ 30 AU, with weak evidence for a decrease toward the Kraichnan index at larger R for the h component. For R ≲ 20 AU the fluctuation level (δn)2(R) decreases approximately as R−3±1 but then flattens out in the region 20–30 AU before increasing slowly for R ≳ 30 AU. This injection of energy into density turbulence beyond 20–30 AU is not a heliolatitude effect and is contrary to the R−4 behavior for (δn)2(R) predicted on the basis of observations inside 1 AU. It is interpreted as the result of charge-exchange and pickup of interstellar neutral atoms for R > 1 AU driving enhanced MHD turbulence and associated density variations. The results provide independent support that observations of proton heating and enhanced magnetic turbulence levels beyond about 20 AU are both real and associated with pickup ions. They also suggest that existing calculations of angular scattering of the 2–3 kHz radiation observed by the Voyagers in the outer heliosphere must be redone and provide opportunities to test turbulence theories by comparing density and magnetic turbulence as a function of R in the outer heliosphere. Owing to limitations on the coverage and quality of data, confirmation of these results using nonspectral methods is desirable.
Drosophila as a Model Organism to Understand the Effects during Development of TFIIH-Related Human Diseases

Human mutations in the transcription and nucleotide excision repair (NER) factor TFIIH are linked with three human syndromes: xeroderma pigmentosum (XP), trichothiodystrophy (TTD) and Cockayne syndrome (CS). In particular, different mutations in the XPB, XPD and p8 subunits of TFIIH may cause one or a combination of these syndromes, and some of these mutations are also related to cancer. The participation of TFIIH in NER and transcription makes it difficult to interpret the different manifestations observed in patients, particularly since some of these phenotypes may be related to problems during development. TFIIH is present in all eukaryotic cells, and its functions in transcription and DNA repair are conserved. Therefore, Drosophila has been a useful model organism for the interpretation of different phenotypes during development as well as the understanding of the dynamics of this complex. Interestingly, phenotypes similar to those observed in humans caused by mutations in the TFIIH subunits are present in mutant flies, allowing the study of TFIIH in different developmental processes. Furthermore, studies performed in Drosophila of mutations in different subunits of TFIIH that have not been linked to any human diseases, probably because they are more deleterious, have revealed its roles in differentiation and cell death. In this review, different achievements made through studies in the fly to understand the functions of TFIIH during development and its relationship with human diseases are analysed and discussed.
A Multi-Trait Association Analysis of Brain Disorders and Platelet Traits Identifies Novel Susceptibility Loci for Major Depression, Alzheimer’s and Parkinson’s Disease

Among candidate neurodegenerative/neuropsychiatric risk-predictive biomarkers, platelet count, mean platelet volume and platelet distribution width have been associated with the risk of major depressive disorder (MDD), Alzheimer’s disease (AD) and Parkinson’s disease (PD) through epidemiological and genomic studies, suggesting partial co-heritability. We exploited these relationships for a multi-trait association analysis, using publicly available summary statistics of genome-wide association studies (GWASs) of all traits reported above. Gene-based enrichment tests were carried out, as well as a network analysis of significantly enriched genes. We analyzed 4,540,326 single nucleotide polymorphisms shared among the analyzed GWASs, observing 149 genome-wide significant multi-trait LD-independent associations (p < 5 × 10−8) for AD, 70 for PD and 139 for MDD. Among these, 27 novel associations were detected for AD, 34 for PD and 40 for MDD. Out of 18,781 genes with annotated variants within ±10 kb, 62 genes were enriched for associations with AD, 70 with PD and 125 with MDD (p < 2.7 × 10−6). Of these, seven genes were novel susceptibility loci for AD (EPPK1, TTLL1, PACSIN2, TPM4, PIF1, ZNF689, AZGP1P1), two for PD (SLC26A1, EFNA3) and two for MDD (HSPH1, TRMT61A). The resulting network showed a significant excess of interactions (enrichment p = 1.0 × 10−16). The novel genes that were identified are involved in the organization of cytoskeletal architecture (EPPK1, TTLL1, PACSIN2, TPM4), telomere shortening (PIF1), the regulation of cellular aging (ZNF689, AZGP1P1) and neurodevelopment (EFNA3), thus, providing novel insights into the shared underlying biology of brain disorders and platelet parameters.
On the stabilization of controllable systems

Conditions are obtained for the asymptotic stabilization of linear dynamical systems through the use of linear state-variable feedback. The procedures developed rely on uniform controllability of the given systems, and yield explicit expressions for the transition matrices of the stabilized systems. As a consequence of the treatment, explicit expressions are obtained for Liapunov transformations which reduce the stabilized systems to canonical (phase-variable) form. Results are given for time-varying multivariable (multi-input) systems.
A Consistent Test for a Unit Root

This article investigates several U.S. macroeconomic time series for the presence of a unit root using a newly developed test. This test has stationarity as its null hypothesis, and the alternative is a unit-root process. The test is shown to be consistent, and its asymptotic null distribution is determined. Our findings contrast sharply with those obtained via the standard unit-root tests.
HOXB9 Overexpression Confers Chemoresistance to Ovarian Cancer Cells by Inducing ERCC-1, MRP-2, and XIAP

The purpose of this study was to identify the role of HOXB9 and associated molecular mechanism in acquiring chemoresistance to ovarian cancer cells. After establishing HOXB9-overexpressing cells (HOXB9-OE/SKOV3), cisplatin resistance-induced cells (Cis-R/SKOV3), and an ovarian cancer xenograft mouse model, the effects of HOXB9 were evaluated in vitro and in vivo. Expression levels of ERCC-1, MRP-2, XIAP, and Bax/Bcl-2 were assessed as putative mechanisms mediating chemoresistance. Cisplatin-induced apoptosis was significantly decreased in HOXB9-OE/SKOV3 compared to SKOV3. Cisplatin treatment of SKOV3 strongly induced ERCC-1, MRP-2, and XIAP, and apoptosis was strongly induced through the inhibition of Bcl-2 and activation of Bax. ERCC-1, MRP-2, XIAP, and Bcl-2 were also strongly induced in HOXB9 OE/SKOV3. In contrast to SKOV3, cisplatin treatment alone of HOXB9 OE/SKOV3 did not affect the expression of Bcl-2 and Bax, and consequently, there was no increase in apoptosis. HOXB9 knockdown suppressed the expression of ERCC-1 and XIAP, but did not affect MRP-2 and Bcl-2/Bax expression in HOXB9 OE/SKOV3 and Cis-R/SKOV3, and caused a small increase in apoptosis. Treatment of SKOV3 with both cisplatin and siRNA_HOXB9 led to complete suppression of ERCC-1, MRP-2, and XIAP, and significantly increased apoptosis through inhibition of Bcl-2 expression and activation of Bax. The results observed in Cis-R/SKOV3 were similar to that in HOXB9 OE/SKOV3. Our data suggest that HOXB9 overexpression may cause chemoresistance in ovarian cancer cells by differential induction of ERCC-1, MRP-2, and XIAP depending on the strength of HOXB9 expression through inhibition of the mitochondrial pathway of apoptosis, including Bax/Bcl-2.
