For centuries, the Ryukyu Kingdom, which was annexed by Meiji Period Japan in 1879 and is today divided among Japan's Okinawa and Kagoshima Prefectures, formed an important linking bridge between China and Japan, East Asia's two dominant political entities. Based on a close reading and partial translation of relevant passages from several historical documents, most notably the kingdom's two official histories Chūzan Seikan and Chūzan Seifu, the thesis investigates the socio-political shift in succeeding conceptualisations of Ryukyuan kingship, the monarch's political legitimacy, and the country's state doctrine that occurred from the late fifteenth and early sixteenth to the seventeenth and eighteenth centuries.Show less

By taking the Stimmungsberichte (mood reports) written by the Wehrmacht, as ledgers of everyday actions performed by the silent majority of the Dutch population, this thesis assesses the fluctuation of nationalistic sentiment in terms of the commonly used repertoires of contention. This leads to a more dynamic perception of nationalism in the Netherlands during this unique time in the history of the nation-state.Show less

This longitudinal study examined whether early physical aggression could be predicted by stress regulation, inhibitory control, risk background, and sex. In addition, this study is among the first to investigate whether the four stress response patterns of the Adaptive Calibration Model (Del Giudice et al., 2011) could be generalized to 12-month-old children by studying: autonomic nervous system (ANS), sympathetic nervous system (SNS), parasympathetic nervous system (PNS), and hypothalamic pituitary adrenal (HPA) axis. ANS was indexed by heart rate, SNS by salivary alpha-amylase and pre-ejection period, PNS by respiratory sinus arrhythmia, and HPA axis by salivary cortisol. The sample consisted of 214 mother-child dyads (116 boys) with an equal number of high- and low-risk backgrounds. Physical aggression was assessed through maternal reports at 12, 20, and 30 months of age. At 12 months, children performed an inhibitory control task and the fear task (robot paradigm) was used to measure baseline, response, and recovery levels of the stress systems. Latent profile analysis revealed three profiles: (1) ANS Responders, (2) Moderate Arousal, and (3) Hormonal Responders. No significant differences were found between the profiles with regard to inhibitory control, average age of mother and child, number of boys and girls, and number of high- and low-risk children. Results showed that higher physical aggression scores were associated at 12 months with ANS Responders and lower inhibitory control, at 20 months with Hormonal Responders, boys and high-risk, and at 30 months with boys and high-risk. In addition, an interaction effect was found at 20 months: higher inhibitory control in girls was associated with lower physical aggression scores, but not in the Hormonal Responders. The discussion highlights the importance of using a multisystem approach to explain individual differences in early physical aggression.Show less

Instead, they break them when the conditions are right. Here we hypothesized that rule abidance behavior is determined by a) an individual choosing another for mutual benefit based on their reputation and b) the social-environmental incentives like fairness and dishonesty. We had three participants building a reputation for their willingness to abide by or break rules. A fourth participant used that information to choose one to three participants, then played several rounds of a dictator game and a die-roll task. Participants were chosen more often when their reputation was in line with environmental incentives, where merely transitioning from one environment to another strengthened that effect. Regulators should therefore ensure the consistency and kinds of environmental incentives that individuals in power positions face across environments for controlling resulting rule abidance behavior.Show less

In a largely separate body of work, psychophysiological predispositions towards threat sensitivity have been linked to ideological constructs. The current work integrates these two bodies of work by introducing a novel approach to measure implicit threat sensitivity and (theoretically) linking it to intergroup prejudice. Specifically, it was investigated whether individual differences in cognitively assessed sensitivity to threatening information were associated with a greater degree of implicit bias and explicit prejudice towards a stereotypically threatening minority-group (i.e., Muslims). While results did not support a relationship between threat sensitivity and intergroup prejudice, exploratory data, as well as limitations and implications of the current work, encourage future research.Show less

However, previous meta-analytic findings indicated that parenting accounted for only 5-11% of the variance in childhood depression, with varying effects for different types of parenting behaviors. Research Question: The current study aimed to investigate the association between observed negative/positive parenting behavior, childhood depression, and child gender, while controlling for the confounding effects of type of informant and assessment approach for childhood depression. Method: Two meta-analysis were conducted for the negative parenting – childhood depression and positive parenting – childhood depression association, while including moderating and confounding variables. The current study included thirty articles in total, with nineteen examining negative parenting behaviors and twenty-three examining positive parenting behaviors. Results: Observed negative parenting behavior was positively and observed positive parenting behavior was negatively related to childhood depression, with overall small effect sizes. Type of parenting behavior, child gender, and assessment approach for childhood depression did not moderate the associations. Type of informant for childhood depression explained some variance in the positive parenting – childhood depression association. Conclusions: Parenting interventions for childhood depression might aim to improve a broader range of parental behaviors. Future research is advised to compare actual to perceived parenting behaviors and investigate the direction of the parenting – childhood depression association, while adopting a multiple levels of analysis perspective. This could possibly contribute towards developing most effective personalized interventions for childhood depression, while lowering the high burden of depression.Show less

This may result in 47,XXY, 47,XXX, or 47,XYY. Previous research suggested that social attention to the eyes is reduced in (young) adults with SCT and that individuals with SCT have more autistic characteristics compared to typically developing (TD) controls. It was unknown whether the group differences were also present in early childhood. The current study aimed to explore social attention, autistic traits, and their relation in three subgroups of children with SCT (47,XXY, 47,XXX, and 47,XYY; N = 70), aged 3 to 7 years, in comparison to TD peers (N = 62). Social attention to the eyes was measured using three eye-tracking video paradigms: A single-face condition, a multiple-face condition and a social interaction condition. Autistic traits were measured using the Social Responsiveness Scale-Second Edition. Results showed a difference in social attention between children with SCT and TD children during the social interaction condition. There was no difference in social attention between the SCT subgroups. The SCT group showed more autistic traits than the TD group and the 47,XXX subgroup had more autistic traits than the 47,XXY subgroup. There was a significant relation between social attention during the single-face condition and autistic traits in the 47,XYY subgroup only. Implications of these findings are discussed in relation to the importance of monitoring socio-cognitive challenges related to SCT in early childhood.Show less

This study tested whether a high score on perceived discrimination is associated with a high score on social anxiety, whether there are gender differences in the non-western group in social anxiety and whether loneliness strengthens the relationship between perceived discrimination and social anxiety. Three classes from three different schools participated, there was a total of 22 participants. To test the hypotheses, the Social Anxiety Scale for Children (SASC-A), Adolescent Discrimination Distress Index (ADDI) and the Asher Loneliness Scale (ALS) have been used as measurements. The results show that there was only a significant difference in gender in social anxiety, girls scored higher in social anxiety than boys. However, this should be interpreted carefully. The other hypotheses were all not significant. Due to the sample size the reliability and validity of this study was not great, so the results are not a good reflection. It is advised to perform this study in a bigger sample size since this is an important matter to the non-western community.Show less

Desde el principio del siglo XX, diversos autores mapuches han producido un levantamiento literario debido al hueco que existe entre la historia enseñada en la escuela sobre tal pueblo y la tradición oral producido en el entorno familiar mapuche. La relación conflictiva entre el estado chileno y los mapuches y la lógica eurocentrista dentro del cual está producido el entorno escolar en Chile han causado que el currículo nacional chileno refleja narrativas históricas hegemónicas. Incluso son identificados como una colonización interna. Como respuesta, hay escritores que han tomado la autonomía para reescribir el pasado desde la perspectiva del pueblo originario. Este estudio explora cómo influye la elaboración de una perspectiva propia de la historia en la construcción de la identidad mapuche en base de dos objetivos. Por un lado, analiza la evolución identitaria e histórica del pueblo mapuche en los manuales escolares de historia desde el inicio de la república al principio del siglo XIX hasta las últimas reformas educacionales en el año 2009. Por otro lado, pone en diálogo el currículo nacional con los libros de historia escritos por autores mapuches: Recado confidencial a los chilenos (1999) de Elicura Chihuailaf, ¡…Escucha Wink…! Cuatro ensayos sobre la Historia Nacional Mapuche y un Epílogo sobre el futuro (2007) de Pablo Marimán et al. y Historia Secreta Mapuche (2017) por Pedro Cayuqueo. De aquí se ha evaluado que estamos frente a una posible narrativa decolonial en cuanto a la historia mapuche, lo cual conlleva un nuevo discurso identitario para el pueblo mapuche.Show less

However, this assumption has never been fully developed within Element Theory. When one attempts to represent complex tonal inventories, it immediately becomes apparent that there are fundamental representational issues. For example, it is unclear how to generate more than two tonal contrasts or how to represent contour tones on short vowels. In this thesis, I consider how these issues could be solved while maintaining Element Theory’s central principles. The two most crucial ideas developed in this thesis are that tone needs to be represented by unheaded elements and that information on the tonal tier is visible during phonetic implementation. With these assumptions, |H| and |L| can freely appear within the same elemental expression and tones do not necessarily need to be specified at the segmental level. The result is a flexible representational system for tone with a restricted but sufficient generative capacity.Show less

This task has therefore been used as a measure of self-directed executive functioning. Previous studies have found that SVF performance improves through childhood and adolescence. This developmentalimprovement has been observed both in the total number of words produced during the task and in switching between subcategories. The present online study tested the hypothesis that the agerelated improvement in SVF performance is partly driven by an improved ability to select between competing word representations. The study included three age groups: 8–10-year-olds (n=26), 12–14-year-olds (n=17), and young adults (n=31). The semantic blocking effect in the blocked cycling naming task was used as a measure of selection abilities. Measures of vocabulary and general processing speed were included as control variables. Age-related differences in SVF performance were only partly replicated: there were signs of age-related differences in the total word count but not in switching. The semantic blocking effect was replicated across age groups. However, there were no signs of age-related differences in the magnitude of this effect, suggesting that word selection abilities did not differ between age groups. Moreover, the magnitude of the semantic blocking effect did not predict SVF performance. Thus, although further research is needed, the present study does not support the hypothesis that the age-related improvement in SVF would be driven by an improvement in selection abilities.Show less

Emotion regulation is commonly impaired in victims of CEM, which can adversely impact broader socio-emotional functioning, such as the quality of child-parent interactions in adolescence. The current study examines to what extent maladaptive emotion regulation strategies (i.e., catastrophizing and rumination) mediate the association between experienced CEM and the quality of child-parent interactions as perceived by the adolescent. METHOD: The healthy control group of the larger RE-PAIR study (‘Unravelling the Impact of Emotional Maltreatment on the Developing Brain’) was included, incorporating adolescents (N = 80, age 11 to17) and their parents (N (Mothers) = 80, N (Fathers) = 76). Adolescent participants performed a reminiscence task with each parent and consecutively filled in a questionnaire to assess perceived parental interaction and communication behaviors during the task. CEM and emotion regulation were assessed through online versions of a Childhood Trauma Questionnaire and a Cognitive Emotion Regulation Questionnaire. RESULTS: Two underlying factors were formulated after performing Principal Component Analyses (PCAs) on the perceived behavior per parent, namely ‘perceived general satisfaction with the interaction’ and ‘perceived criticism’. CEM did not predict either formulated outcome, for parents together and mothers separately. However, CEM had a negative effect on perceived general satisfaction, (F(1,64) = 6.175, b = -.502, p = .016) and a positive effect on perceived criticism, (F(1,64) = 6.612, b = .127, p = .012) by the adolescent during the interaction with their father. No mediation effects were found for either catastrophizing or rumination. DISCUSSION: Suggestions for future research include comparisons between different childhood maltreatment and to assess emotion dysregulation on multiple levels of functioning.Show less

Linking test scores to T scores as a common metric might be a solution. Item response theory (IRT) is the preferred way to estimate T-scores. However, required software and a large dataset is needed for that. In this thesis, two methods were used to arrive at a common metric for often used questionnaires and their subversions: the BSI, BSI-18, the DASS-42 and the DASS-21. As one method, we used an IRT approach to estimate theta-based T-scores, leading to crosswalk tables. For the second approach, conversion formulas were estimated for raw scores to calculated T-scores based on the best-fitting regression equation between the raw scores and the previously estimated theta-based T-scores. Crosswalk tables and conversion formulas are both alternative ways to link individual scores to a common metric. It was investigated if conversion formulas are valid by comparing calculated T-scores with theta-based T-scores. The agreement between calculated T-scores and theta-based T-scores were high for all questionnaires except the DASS-42. The agreement was also lower at the extreme ends of the questionnaires (T= < 50 and T= >75). All in all, conversion formulas seem to be a good alternative for estimating a common metric. Offering different options to calculate common metrics can help in improving the communication between professionals in the clinical field. Increased involvement and better communication in ROM is able to increase the quality of mental health care.Show less
