    Education is a part of society that affects everyone; it has to thrive in order for future generations to succeed in taking our place. For this reason, it is often debated how to best construct an education system that will be most effective. Through this debate comes the need for reform to morph education systems to fit the changing times and the fluctuating educational needs produced by the progression of time. By identifying Finland as a leading nation in the education world and as something to strive for, we can compare it to the underperforming education system of the United States to explore where the differences lie and how they impact student success rates as shown on the Programme for International Student Assessment. Before diving into educational variations, we look first at a whole picture view of the two countries to gain an idea of the societal context in which to analyze the dissimilarities in their education systems, as well as a background of the ideological fundamentals that form the foundation of their school structures. After gaining a deeper understanding of the social features and common beliefs surrounding education, the reform movements and current education systems of the two countries will be compared side by side, leading up to the identification of areas of Finnish success that can be modified to meet the needs of the United States

    Visual adaptation to thin and fat bodies transfers across identity

    Visual perception is highly variable and can be influenced by the surrounding world. Previous research has revealed that body perception can be biased due to adaptation to thin or fat body shapes. The aim of the present study was to show that adaptation to certain body shapes and the resulting perceptual biases transfer across different identities of adaptation and test stimuli. We designed two similar adaptation experiments in which healthy female participants adapted to pictures of either thin or fat bodies and subsequently compared more or less distorted pictures of their own body to their actual body shape. In the first experiment (n = 16) the same identity was used as adaptation and test stimuli (i.e. pictures of the participant’s own body) while in the second experiment (n = 16) we used pictures of unfamiliar thin or fat bodies as adaptation stimuli. We found comparable adaptation effects in both experiments: After adaptation to a thin body, participants rated a thinner than actual body picture to be the most realistic and vice versa. We therefore assume that adaptation to certain body shapes transfers across different identities. These results raise the questions of whether some type of natural adaptation occurs in everyday life. Natural and predominant exposure to certain bodily features like body shape – especially the thin ideal in Western societies – could bias perception for these features. In this regard, further research might shed light on aspects of body dissatisfaction and the development of body image disturbances in terms of eating disorders

    Monte Carlo Simulations of Star Clusters - IV. Calibration of the Monte Carlo Code and Comparison with Observations for the Open Cluster M67

    Full text link
    We outline the steps needed in order to incorporate the evolution of single and binary stars into a particular Monte Carlo code for the dynamical evolution of a star cluster. We calibrate the results against N-body simulations, and present models for the evolution of the old open cluster M67 (which has been studied thoroughly in the literature with N-body techniques). The calibration is done by choosing appropriate free code parameters. We describe in particular the evolution of the binary, white dwarf and blue straggler populations, though not all channels for blue straggler formation are represented yet in our simulations. Calibrated Monte Carlo runs show good agreement with results of N-body simulations not only for global cluster parameters, but also for e.g. binary fraction, luminosity function and surface brightness. Comparison of Monte Carlo simulations with observational data for M67 shows that is possible to get reasonably good agreement between them. Unfortunately, because of the large statistical fluctuations of the numerical data and uncertainties in the observational data the inferred conclusions about the cluster initial conditions are not firm.Comment: 15 pages, 24 figure

    Star Clusters

    Full text link
    This review concentrates almost entirely on globular star clusters. It emphasises the increasing realisation that few of the traditional problems of star cluster astronomy can be studied in isolation: the influence of the Galaxy affects dynamical evolution deep in the core, and the spectrum of stellar masses; in turn the evolution of the core determines the highest stellar densities, and the rate of encounters. In this way external tidal effects indirectly influence the formation and evolution of blue stragglers, binary pulsars, X-ray sources, etc. More controversially, the stellar density appears to influence the relative distribution of normal stars. In the opposite sense, the evolution of individual stars governs much of the early dynamics of a globular cluster, and the existence of large numbers of primordial binary stars has changed important details of our picture of the dynamical evolution. New computational tools which will become available in the next few years will help dynamical theorists to address these questions.Comment: 10 pages, 3 figures, Te

    The X-ray source population of the globular cluster M15: Chandra high resolution imaging

    Full text link
    The globular cluster M15 was observed on three occasions with the High Resolution Camera on board Chandra in 2001 in order to investigate the X-ray source population in the cluster centre. After subtraction of the two bright central sources, four faint sources were identified within 50 arcsec of the core. One of these sources is probably the planetary nebula, K648, making this the first positive detection of X-rays from a planetary nebula inside a globular cluster. Another two are identified with UV variables (one previously known), which we suggest are cataclysmic variables (CVs). The nature of the fourth source is more difficult to ascertain, and we discuss whether it is possibly a quiescent soft X-ray transient (qSXT) or also a CV.Comment: 9 pages, 6 figures, accepted for publication in MNRAS.

    Memories of shame experiences with others and depression symptoms: the mediating role of experiential avoidance

    Get PDF
    Background: Shame experiences have been suggested to be related with psychopathological symptoms and with self-relevant beliefs. Recent studies also suggest that avoidant-focused strategies (e.g., rumination, thought suppression and dissociation) mediate the impact of shame memories and depression symptoms. However, experiential avoidance has been found to mediate the relation between early experience of abuse and psychopathological symptoms. Our goal was to test the mediating effect of experiential avoidance in the relation between both the nature of shame experiences at the hands of caregivers and the centrality of shame memories with others, and depression symptoms. Method: Using structural equation modelling, we assessed the frequency and nature of recalled shame experiences at the hands of caregivers, the centrality of shame experiences with others throughout childhood and adolescence, experiential avoidance and depression symptomatology in 161 participants from general population. Results: Experiential avoidance mediates the impact of shame experiences with caregivers and depression symptoms. Experiential avoidance also mediated the association between the centrality of shame experiences with others and depression symptoms. Conclusion: Our results suggest that shame memories with others do not per se impact on depression symptoms, but rather the unwillingness to experience them and the attempts to control them. Hence, our results emphasize the importance of addressing affect regulation processes such as avoidance when dealing with shame memories, particularly with patients who experience depression symptoms

    Genotype-phenotype relationships of truncating mutations, p.E297G and p.D482G in bile salt export pump deficiency

    Background &amp; Aims: Bile salt export pump (BSEP) deficiency frequently necessitates liver transplantation in childhood. In contrast to two predicted protein truncating mutations (PPTMs), homozygous p.D482G or p.E297G mutations are associated with relatively mild phenotypes, responsive to surgical interruption of the enterohepatic circulation (siEHC). The phenotype of patients with a compound heterozygous genotype of one p.D482G or p.E297G mutation and one PPTM has remained unclear. We aimed to assess their genotype-phenotype relationship. Methods: From the NAPPED database, we selected patients with homozygous p.D482G or p.E297G mutations (BSEP1/1; n = 31), with one p.D482G or p.E297G, and one PPTM (BSEP1/3; n = 30), and with two PPTMs (BSEP3/3; n = 77). We compared clinical presentation, native liver survival (NLS), and the effect of siEHC on NLS. Results: The groups had a similar median age at presentation (0.7-1.3 years). Overall NLS at age 10 years was 21% in BSEP1/3 vs. 75% in BSEP1/1 and 23% in BSEP3/3 (p &lt;0.001). Without siEHC, NLS in the BSEP1/3 group was similar to that in BSEP3/3, but considerably lower than in BSEP1/1 (at age 10 years: 38%, 30%, and 71%, respectively; p = 0.003). After siEHC, BSEP1/3 and BSEP3/3 were associated with similarly low NLS, while NLS was much higher in BSEP1/1 (10 years after siEHC, 27%, 14%, and 92%, respectively; p &lt;0.001). Conclusions: Individuals with BSEP deficiency with one p.E297G or p.D482G mutation and one PPTM have a similarly severe disease course and low responsiveness to siEHC as those with two PPTMs. This identifies a considerable subgroup of patients who are unlikely to benefit from interruption of the enterohepatic circulation by either surgical or ileal bile acid transporter inhibitor treatment. Impact and implications: This manuscript defines the clinical features and prognosis of individuals with BSEP deficiency involving the combination of one relatively mild and one very severe BSEP deficiency mutation. Until now, it had always been assumed that the mild mutation would be enough to ensure a relatively good prognosis. However, our manuscript shows that the prognosis of these patients is just as poor as that of patients with two severe mutations. They do not respond to biliary diversion surgery and will likely not respond to the new IBAT (ileal bile acid transporter) inhibitors, which have recently been approved for use in BSEP deficiency.</p
